Answer 1

Answer:

✯HEART ✯

As a central part of the circulatory system, the heart is primarily responsible for pumping blood and distributing oxygen and nutrients throughout the body. Because of this task, the heart may be considered one of the most important organs of the body, such that even small dysfunctions or abnormalities may cause drastic changes or effects in the human organism.

✯Structure of the heart ✯

The heart can be found at the chest's center, underneath the sternum in a thoracic compartment. It comprises four chambers and several valves that regulate the normal flow of blood within the body.Two chambers called atria are located in the upper portion of the heart with the left atrium receiving oxygen-rich blood and the right receiving oxygen-free blood. The valves that separate these chambers are called atrioventricular valves, composed of the tricuspid valve on the left and the mitral valve on the right.On the other hand, ventricles are chambers found on the lower portion of the heart; they pump oxygen-enriched blood into the body's organs, reaching even the smallest cells. Similar to the atria, valves also separate the ventricular chambers. Collectively-termed as semilunar valves, these are comprised of the pulmonary and aortic valves.

✯Function of the heart ✯

The heart is the main organ in the circulatory system, the structure is primarily responsible for delivering blood circulation and transportation of nutrients in all parts of the body. This continuous task uplifts the heart's role as a vital organ whose normal operation is constantly required.The heart’s blood-pumping cycle, called the cardiac cycle, ensures that blood is distributed throughout the body.

Answer 2

Answer:

( HEART )

The heart works as two pumps, one on the right and one on the left, working simultaneously. Blood flows from the right atrium to the right ventricle, and then is pumped to the lungs to receive oxygen. From the lungs, the blood flows to the left atrium, then to the left ventricle.

◍What are the four main functions of the heart:

◕Pumping oxygenated blood to the other body parts.

◕Pumping hormones and other vital substances to different parts of the body.

◕Receiving deoxygenated blood and carrying metabolic waste products from the body and pumping it to the lungs for oxygenation.

◕Maintaining blood pressure.
