Q1-Write down the functions of all chambers of heart?​

Answer 1

$\huge \red{answer}$

Heart chamber is a general term used to refer to any chambers of the mammalian heart. The heart consists of four chambers: the right and left atrium and the right and left ventricle. The top chambers are connected to the bottom chambers by valves and are separated by the coronary sulcus. The left and right side of the heart are separated by the posterior interventricular sulcus.

Answer 2

Explanation:

The heart is the main organ in the circulatory system, the structure primarily responsible for delivering the circulation of blood and transportation of nutrients in all parts of the body. This continuous task uplifts the role of the heart as a vital organ whose normal operation is constantly required.

The heart’s blood-pumping cycle, called cardiac cycle, ensures that blood is distributed throughout the body. The oxygen distribution process begins when oxygen-free blood enters into the heart through the right atrium, goes into the right ventricle, enters the lungs for oxygen refill and release of carbon dioxide, and transfers into the left chambers, ready for redistribution. About 5.6 liters of blood circulate the body and three cardiac cycles are completed per minute.

The performance of the heart could now be easily monitored when any cardiovascular problem or disorder is suspected. For instance, a regularly abnormal heartbeat or beats per minute are characteristic of a heart-related illness. This is because a heartbeat is a manifestation of the oxygen-reloading process in the heart that is made up of two phases.

The systole is a short period that occurs when the tricuspid and mitral valves close; the diastole is a relatively longer period when the aortic and pulmonary valves close. The systole-diastole relationship is the reference in measuring blood pressure. Other ways of physically determining the regular functioning of the heart is through examining the pulse rate (beats per minute). A normal heart rate of an adult is at 72 beats per minute, while children normally yield higher heart rates.
