Hello dear steemian friends,

Best wishing to all.
I hope you are best

Now I want to share with you"System Human Anatomy"

Let's get started,

Introduction-

Circulatory System Of Human Anatomy,
The human blood circulation system is a complex process that continues from the mother's womb to the moment before death.

It is also called the cardiovascular system of human.

In a word, it refers to the systematic functioning of all the organs associated with the human heart.

What we will learn in today's article is-

1.What is Circulatory System?
2.What is a heart?
3.The structure of the heart.
4.Heart or heart layer.
5.Heart's blood nerve supply.
6.Blood circulation of the heart.
7.Heart sound and pump.
Conclusion.

1.Circulatory System-

Circulatory System Human Anatomy refers to the circulatory system of the human body such as the heart, lungs, arteries, aorta, veins, sub-veins.
I understand all the activities.

2.What is the heart?

Circulatory System The main organ of human anatomy is the heart.

The heart is a moving device that looks like a corner of the human body shaped like a hollow muscular bean seed. Base on top and Apex on the bottom.

The location of this heart in the human body is where there is a large hole or notch in the left side of the chest.

Moreover, it is located 1/2 (half) inch below the nipple on the left side of the chest. It is behind the sternum and ribs.

3.The structure of the heart: -

The shape of a heart is the size of a full-grown man when he closes his fist or fist in his hand. It weighs 8 to 9 ounces.

This heart has four chambers. They are-
(1) Right Atrium
(2) Right ventricle
(3) Left atrium or Left Atrium
and
(4) Left ventricle*

There is a gap or opening between the atrium and the ventricle on both sides. Here it is blocked by a valve. Here blood can go down from the top but cannot go up.

The name of the right side is Tricuspid Valve.
The one on the left is Bicuspid or Mitral Valve

4.Heart Layer: -

In Circulatory System Human Anatomy we will learn about the layer of the heart.
The tissue that covers the inside of the heart is called the endocardium vessel.

The total layer of the heart is three. E.g.

(i) Upper lining or Pericardium
(ii) Myocardium
and
(iii) Endocardium

5.Heart's blood nerve supply: -

The coronary arteries nourish the heart muscles. It first comes out of the aorta. It supplies blood to all the muscles of the heart. It then sends contaminated blood into the coronary veins.

From here the blood goes straight back to the right atrium. Coronary disease is when blood gets stuck in these arteries or veins. Which is a deadly disease. This disease can lead to death.

The heart has two nerves on each side.
Vegas nerve and sympathetic nerve.

6.Blood circulation in the heart: -

Heart function or cardiac cycle is a fun thing. The neck, head and all the veins of the hand end in Superio vana cava.

They carry unclean blood. Blood from other parts of the body, such as the legs, reaches the inferior vena cava.

These two Vena Cava bring impure blood from different parts of the body to the Right Atrium. There, through the Tricuspid Valve, this impure blood enters the Right Ventricle. This blood is then pumped through the pulmonary artery and goes straight to the lungs.

Here the blood is purified and fed to the four pulmonary veins in the Left Arium. Pure blood is pumped to the left ventricle and spread to different parts of the body through the aortar.

7.Heart sound and pump: -

There are two types of heart. These two words are "lab" and "dub". The first term is made for the valve between the atrium and the ventricle.

And the second word is for Aortic and Pulmonary Velve. The heart pumps blood 72 to 80 times per minute and sends it to different parts of the body.

Conclusion: -

In conclusion, it can be said that the heart is a very important organ in the human body without which human beings could not survive. The heart is the main component of the body. Which governs the whole body.
