what is the function of heart?
Answers
Arterial blood (red, oxygen-rich blood) flows from the heart to each part of the body to provide oxygen and nutrients. The venous blood (blue, oxygen-poor blood) returns from the body to the heart. The blood then travels through the lungs to exchange carbon dioxide for new oxygen. The heart is a pump, which moves the blood. The arteries and veins are the pipes through which the blood flows. The lungs provide a place to exchange carbon dioxide for oxygen.
HUMAN HEART :
》Human Heart is mesodermal in origin.
》It is located in the thoracic cavity between the lungs.
》It is protected by pericardium which is a double walled membrane enclosing pericardial fluid.
》Our heart consists of four chambers - two upper chambers called atria and two lower chambers called ventricles.
》A thick walled septum called the inter-ventricular septum separates the left and right ventricles.
》A thin septum called inter-atrial septum separates right and left atria.
》Atrioventricular septum separates the atria and the ventricle of the same side.
》Bicuspid Valve regulates the opening between the left atrium and left ventricle.
》Tricuspid Valve regulates the opening between the right atrium and right ventricle.
FUNCTION :
● The function of Heart is to pump oxygenated blood to all the parts of our body and also to pump the deoxygenated blood from lungs to heart.
