CARDIOVASCULAR SYSTEM
मानव हृदय की संरचना सीखे सरल भाषा में

CARDIOVASCULAR SYSTEM (CVS)
It is one of the major organ system of body associate with the supply of blood to different parts of the body.
Also called The blood circulatory system
Its main function to delivers nutrients and oxygen to all cells in the body.
The main organ of CVS is heart
It have large collection of blood vessels

CARDIOVASCULAR SYSTEM (CVS)
The essential components of human cardiovascular system
1. The heart,
2. The blood
3. The blood vessels
It Circulate and transport nutrients, amino acids electrolytes, oxygen, carbon dioxide, hormones, blood cells.

CARDIOVASCULAR SYSTEM (CVS)
Circulatory system help us in following way
Provide nourishment
help in fighting diseases,
stabilize temperature & pH,
maintain homeostasis.
During disease condition also transport drug molecules and help to treat that condition

THE HUMAN HEART: NATURAL PUMP
The heart is a muscular organ in most animals, which pumps blood through the blood vessels of the circulatory system.
The pumped blood carries oxygen and nutrients to the body, while carrying metabolic waste such as carbon dioxide to the lungs.

FACTS ABOUT HUMAN HEART
The heart beats around 100,000 times a day
Pumping approximately 4,500 to 5,700 ml of blood of body throughout the body.
It pumps about 55-80 ml (1/3 cup) of blood with each beat for adults
Around 25-85 ml per beat for children.
A normal resting heart rate for adults ranges from 60 to 100 beats per minute.
Heart sound like “lub dub”

FUNCTIONS OF HEART
The four main functions of the heart are:
1. Pumping oxygenated blood to the other body parts.
2. Pumping hormones and other vital substances to different parts of the body.
3. Receiving deoxygenated blood and carrying metabolic waste products from the body and pumping it to the lungs for oxygenation.
4. Maintaining blood pressure.

HEART SCHEMATIC DIAGRAM

The heart consists of four chambers:
The atria: These are the two upper chambers, which receive blood.
The ventricles: These are the two lower chambers, which discharge blood.

Two pathways come from the heart:
The pulmonary circulation is a short loop from the heart to the lungs and back again.
The systemic circulation carries blood from the heart to all the other parts of the body and back again.
