What main function of aorta?

• Blood flows into the right ventricle

• Blood flows into the left ventricle

• Transports oxygenated blood to whole body

• Transports deoxygenated blood from the heart

What function of pulmonary artery?

• Transports deoxygenated blood from heart to lungs

• Fibrinogen plays a role on blood clotting

• Albumin controls blood osmotic pressure

• Oxygen is required in the respiration of cells

It separates the left part of the heart from the right part of the heart and ensures that the oxygenated blood does not mix with the dexygenated blood. What is It?

• Vena cava

• Septum

• Semilunar valves

Why muscular wall of the left ventricle is much thicker than muscular wall of the right ventricle?

• Left ventricle has to generate greater pressure

• Right ventricle has to generate greater pressure

• Left ventricle has to pump blood to the lungs.

• Right ventricle has to pump blood to the lungs.

Coronary veins transport oxygenated blood for heart while coronary arteries transport deoxygenated blood.
