Question

describe the blood flow around the circulartory system?

what is the oxygen content in the major area of the circulatory system?

Answer 1

Blood flow around the circulatory system

• Blood circulation begin when the heart relaxes between heart beat.
• They are two types of circulation in the circulatory system

1. Pulmonary circulation

• In pulmonary circulation the right ventricle which contains little oxygen and which in carbon dioxide which pumps blood into the pulmonary artery and branches into little capillaries which surrounds tiny vesicles called air sacs this is where carbon dioxide is droped and oxygen is picked up.
• When we breath out the CO2 that was removed from the blood is exhaled and fresh O2 is brought into the lungs.oxygen rich blood is return to the heart via the pulmonary vein in to the left atrium and to the left ventricle. After this systemic circulation begins

2. Systemic circulation

• In systemic circulation the left ventricle which contains the oxygenated blood enters the aorta and pump to various part of the body.

The major areas where oxygenated blood is present pulmonary vein, left atrium, left ventricle, aorta, arteries, arterioles and capillaries.
