What is the correct sequence of blood flow
Answers
Correct Question:
Which of the following is a correct sequence of the flow of blood in a systemic circulation?
A) Heart →aorta →arteries →arterioles →capillaries → tissues →venules →veins →superior and inferior vena cava →heart
B) Heart → pulmonary artery → lungs →pulmonary veins → Heart
C) Heart → pulmonary veins → lungs →pulmonary artery →Heart
D) Heart →venules →veins →capillaries →tissues →Aorta →arteries →arterioles →superior and inferior vena cava →heart
Answer:
Option A) is the correct
Heart →aorta →arteries →arterioles →capillaries → tissues →venules →veins →superior and inferior vena cava →heart
Pulmonary circulation is the movement of blood through the pulmonary artery and vein between the heart and lungs.
Whole process:
- The flow of blood between the heart and various bodily components is known as systemic circulation.
- All regions of the body receive oxygen-rich blood through the aorta, an artery that emerges from the left ventricle of the heart.
- A network of arteries that further divides into arterioles and capillaries carries the oxygenated blood into the aorta.
- The tissues receive oxygen through the capillaries.
- Carbon dioxide diffuses into the blood from the tissues.
- The venules subsequently gather the deoxygenated blood, which is then transported by the veins and vena cava.
- Deoxygenated blood is collected from the upper and lower halves of the body via the superior vena cava and the inferior vena cava, respectively.
- The right atrium of the heart subsequently receives this deoxygenated blood.
