Anatomy of human heart:-

Video of human heart anatomy, 😍👇

The heart is a muscular organ that serves to collect deoxygenated blood from all parts of the body, carries it to lungs it to the lungs and release carbon dioxide. then it transports oxygenated blood from lungs and distributes it to the body parts.

• the heart pumps around 72000 liters of blood in a day throughout the body.
• The heart is situated at the center of the chest and points slightly towards the left.
• on average, the heart beats about 100,000 times a day, around 3 billion beats in a lifetime.

• An adult heart beats about 60 to 80 per minutes, and new born baby heart beat 70 to 190 beats per minute.

• ANATOMY::-

• the heart is conical hollow muscular organ situated int he middle mediastinum and is enclosed with in the pericardium.

Layers of the heart wall:

The heart  wall consists of three layers enclosed in the pericardium.

1. Epicardium
2. Myocardium
3. Endocardium

CHAMBERS OF  THE HAERT

• Right atrium
• Right ventricle
• Left atrium
• left ventricle
• The two atria are thin walled chambers that receive blood from veins. The two ventricles are thick walled chambers that forcefully pump blood out of the heart.

The right  atrium  receives deoxygenated blood from systemic veins , the left atrium receives oxygenated blood from the pulmonary veins.

Valves of the heart:-

Pumps need a set of valves to keep the fluid flowing in one direction and the heart is no exception. the heart has two types of valves that keep the blood flowing in the correct direction. 

the valves between the atria and ventricles are called atrioventricular valves, while those at the bases of tge large vessels leaving the ventricles are called semilunar valves.
