Cardiovascular efficiency - Recovery rate - 4How is blood pumped around the body?The blood is pumped around the body by the contractions of the heart.
The blood leaves the heart, via the arteries and capillaries.
Then the blood flows back to the heart via the veins. - 5Why is blood under pressure in arteries?Blood in the arteries is under pressure because of the contractions of the heart muscles. This allows the blood to reach all parts of the body.
- 6What unit is blood pressure measured in?Blood pressure is measured in millimeters of mercury, mmHg.
- 7What are the 2 measurements of blood pressure?systolic pressure - the higher measurement
diastolic pressure - the lower measurement - 8What blood pressure should a young, fit person have?A young, fit person should have a blood pressure of about 120 over 70.
- 9What are the causes and problems of high and low blood pressure?
- 10How does smoking increase blood pressure?Nicotine itself increases the heart rate. Carbon monoxide combines with haemoglobin, preventing oxygen combining with it. This causes an increase in blood pressure to compensate for the reduced amount of oxygen in the blood.
- 11How does saturated fats affect the heart?Cholesterol builds up forms plaque.
The hard outer layer of the plaque is cracked and the softer layer is exposed - causing platelets to stick to it - a thrombosis is formed.
This narrows arteries - restricting the flow of blood. The thrombosis could also detach and block smaller blood vessels.
This results in the heart muscle receiving no oxygen and dying. - 12What sticks to plaque and narrows arteries?Platelets
- 13What is a blood block called?Thrombosis
- 14How does salt increase the risk of getting a heart attack?Eating too much salt causes high blood pressure. This increases the risk of damaging the arteries - encouraging the build up of plaques.
