Question 23

Roles of Platelets

Answer 23

Produces clotting substances and prevents harmful blood loss when vessel is damaged

Question 24

What does the Heart do

Answer 24

Circulates blood byt contracting rhythmically through the cardiac cycle (Diastole: filling, Systole: pumping)

Question 25

Describe the cycle

Answer 25

Deoxygenated blood into the heart (Vena cava) to Right atrium to ventricle into the lungs (Pulmonary artery). Gaseous exchange in the lungs. Now the oxygenated blood back to the hear (Pulmonary vein) into the left atrium and ventricle, out into the body (Aorta) to assist in energy production. In the body, 02 into muscles, C02 back into blood cells
