Question

how is your heart pumping and where it it is located​

Answer 1

$\huge\bold{Answer}$

$\boxed{\textbf{Heart}}$

Heart is a muscular organ that pumps out the blood into the vessels.

It's the size of our own fist.

It is situated between the lungs slightly tilted towards the left.

Human heart is four chambered.

Its four different chambers are meant to prevent the mixing of oxygenated or oxygen rich and deoxygenated or carbon dioxide rich blood.

The chambers are right atrium, left atrium, right ventricle, left ventricle.

$\boxed{\textbf{Working}}$

Left atrium recieves oxygenated blood from the lungs via pulmonary vein.

The left atrium during this process relaxes.

It contracts while left ventricle expands, so blood is transferred to it.

As the left ventricle contracts, the blood is then pumped out for circulation in the body.

Deoxygenated blood enters to the right atrium as it expands.

When the right atrium contracts the corresponding lower chamber i.e., The right ventricle dilates.

Deoxygenated blood thus, enters in it which inturn is pumped to lungs for oxygenation.

●Valves are the muscular flaps that prevent the back-flow of blood.

●Septum is a muscular wall that prevents mixing of oxygenated and deoxygenated blood.

Answer 2

The human heart is an important muscular organ involved in pumping blood to different parts of the body with the help of three segments of the circulatory system:

The pulmonary circulation ( heart and lungs ),

The systemic circulation (body systems) and

The coronary circulation (blood vessels of the heart).

The coronary circulation is an essential system to the heart as it circulates blood from the main artery – that comes from the heart. It also plays a vital role in supplying oxygen, nutrients and removing carbon dioxide and other wastes through the circulatory system.
