1. The circulatory system is made up of the age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes and the blood vessels. The heart is a age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes organ that age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes blood around the body. 2. The three main types of blood vessels are arteries, veins and age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes . Blood is carried away from the heart in age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes and back to the heart in age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes . Capillaries are tiny blood vessels found in body tissues. They form a age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes allowing blood to flow from arteries to veins. 3. Blood carries age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes , oxygen, age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes and waste round the body. Capillaries are thin-walled and therefore allow nutrients and age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes in the blood out to the tissues and carbon dioxide and age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes to pass from the tissues into the blood. 4. Each time the heart beats, it pushes blood into the arteries making them swell. This movement is called age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes . It can be measured using high-tech instruments such as a age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes or a heart rate monitor or low-tech instruments such as a stethoscope and a age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes . 5. A person’s pulse rate depends on several factors such as their size, age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes , age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes and level of fitness. A high resting pulse rate may lead to heart age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes . 6. The time taken for pulse rate to return to normal after exercise is called age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes time. A combination of age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes resting pulse rate and age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes recovery time may indicate high level of fitness. Resting pulse rate and recovery time can be reduced by age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes regularly. 7. Blood that has been pumped into arteries is under pressure. This blood age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes can be measured using low-tech instruments called age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes and mercury age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes or a high-tech instrument called a age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes sphygmomanometer. A normal average upper value for blood pressure would be 120 and a lower value would be 80 (written as 120/80 for short). Readings over 160/90 indicate age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes blood pressure. 8. High blood pressure can be caused by : being age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes , not taking enough exercise, eating a diet containing too much age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes or salt or drinking alcohol to age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes . High blood pressure can lead to age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes , heart attacks and age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes . Low blood pressure can indicate heart age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes . 9. Blood can be tested to detect several medical conditions. Infection is indicated by the presence of age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes . age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes is indicated by a low iron content, diabetes by a high level of age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes and age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes by an abnormally high white blood cell count. 10. Before being used for a blood transfusion, blood has to be tested to find out its blood age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes since some blood groups clump in the presence of others instead of mixing freely. Blood is also tested for age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes concentration in cases of suspected drunk driving.age alcohol Anaemia angina antibodies arteries capillaries digital disease excess exercising failure fat group heart high leukaemia link low manometer muscular nutrients overweight oxygen pressure pulse pulsometer pumps recovery sex short stethoscope stopwatch strokes sugar veins wastes
