describe the working of human heart?
Answers
The human heart is an organ that pumps blood throughout the body via the circulatory system, supplying oxygen and nutrients to the tissues and removing carbon dioxide and other wastes. ... "If [the heart] is not able to supply blood to the organs and tissues, they'll die."
Human heart:
THE HEART IS A MUSCULAR ORGAN AS BIG AS OUR FIST.
HUMAN HEART HAS DIFFERENT CHAMBER TO PREVENT OXYGEN RICH BLOOD FROM MIXING WITH THE BLOOD CONTAINING CARBON DIOXIDE.
the circulation part in human heart:
Heart has two upper receiver chamber called atria. it has two lower chamber called ventricles which can push blood out of the heart.
in left chamber:
1. Oxygen rich blood from the lungs comes to the thin walled upper left Chamber of the heart that means left Atrium through pulmonary veins.
2. the left Atrium relax when it is collecting this blood.
3. Now, left Atrium contract, while left ventricle relaxes.
4. So, that the blood is transferred to left ventricle.
5. When the muscular left ventricle contract the blood is pumped through aorta and supply to the whole body.
in right chamber:
1. Deoxygenated blood come from the body to the upper right chamber that means right atrium as it relaxes.
2. As the right atrium contract the corresponding lower chamber the right ventricle dilates.
3. This transfer deoxygenated blood to the right ventricle, which turn pump it through pulmonary artery to the lungs for oxygenation.
notes:
Values ensure that blood does not flow backwards when the artery or ventricle contract.
Since ventricle have to pump blood into various organ, they have thicker muscular walls, than the atria do.
Hope this help you!!!!!
