Function of heart explain
Answers
Answer:
Explanation:
Knowing the functions of the cardiovascular system and the parts of the body that are part of it is critical in understanding the physiology of the human body. With its complex pathways of veins, arteries, and capillaries, the cardiovascular system keeps life pumping through you. The heart, blood vessels, and blood help to transport vital nutrients throughout the body as well as remove metabolic waste. They also help to protect the body and regulate body temperature.
The cardiovascular system consists of the heart, blood vessels, and blood. This system has three main functions:
Transport of nutrients, oxygen, and hormones to cells throughout the body and removal of metabolic wastes (carbon dioxide, nitrogenous wastes).
Protection of the body by white blood cells, antibodies, and complement proteins that circulate in the blood and defend the body against foreign microbes and toxins. Clotting mechanisms are also present that protect the body from blood loss after injuries.
Regulation of body temperature, fluid pH, and water content of cells.
Hey looking nice in the picture
follow of blood
- during the diastolic stage , the deoxygenated blood from various organ passes through superior and inferior vena cava and reaches the right atrium
- when the right artium is full of blood ,it contrasts, and the valve opens under prespressure, then the blood is forced into the right ventricle
-the right ventricle contract and the blood is pumped into the artery (the only artery which carries co² with blood ),which take it to the lungs from diffusion and change of gases
-the oxygenated blood returns to the heart through the permanently veins (the only veins which carries oxygenated rich blood )
and post it into the left Atrium
-when the left Atrium is full of blood, the valve open and lets the blood flow into the left ventricle
-
on the contraction of the left ventricle, the blood is taken to the largest artery i.ethe Eritrea which carries the blood all over to the body
