Heart

Question 1

What are the two systems in the circulatory system

Answer 1

Systemic system which will supply oxygenated blood to restoring cells all across the body and the pulmonary system which will be connecting the lungs to the heart

Question 2

Name the two types of valves

Answer 2

Atrioventricular valve (bicuspid and tricuspid cables), 
Semi lunar valves (aortic valve and pulmonary valve)

Question 3

Equation to find the cardiac output

Answer 3

Cardiac output= stroke volume x heart rate

Question 4

Formation of atheroma from atherosclerosis

Answer 4

LDL build up in the blood vessel which will cause an immune responce which will cause the fatty cells (foam cells) to get bigger and a fiberous cap may form to make it ridged until it bursts to form a thrombosis

Question 5

What causes the lub in the heart?

Answer 5

The closing of the atrioventricular valve

Question 6

What causes the dub sound of the heart?

Answer 6

The closing of the semi lunar valves in both the aortic valve and the pulmonary artery valve

Question 7

Explain how blood circulates in the pulmonary system

Answer 7

Right atrium will contract to increase pressure to push deoxygenated blood into the right ventricle. Once filled the AV valve will close fro the chordae tendineae when the right ventricle contracts. The increase in pressure I the right ventricle will push deoxygenated blood through the pulmonary semi lunar valve into the pulmonary artery, this leads to both lungs to be oxygenated then move into the pulmonary vein to the left atrium.
