Answer #1

Ans.A)oxygenated blood comes in to the hearts left atrium, is pumped into the left ventricle, then pushed throughout the body.

Heart is divided into four chambers- two atria and two ventricles.

Right atrium receives deoxygenated blood from superior and inferior vena cava and from coronary sinus.

Blood then moves to right ventricle and then to lungs for oxygenation.

Now oxygenated blood from lungs enters the left atrium and then pumped to left ventricle and finally it is pumped into aorta for distribution to various body parts and organs.

Oxygen-rich blood bound for the body tissues leaves the heart through the aorta, the major blood vessel emerging from the heart. It branches out to the arteries, which in turn branch into smaller vessels called arterioles (little arteries). These then branch into tiny, thin-walled capillaries. Blood travels slowly as the red blood cells squeeze through tiny capillaries. The radius of the aorta is approximately 9.8 mm and the speed of the blood there is 30 cm/s. A typical capillary has...
