The human heart is a remarkable organ, playing a central role in sustaining life. It functions as the engine of the circulatory system, responsible for pumping blood throughout the body to supply oxygen and essential nutrients to tissues and organs.
Structure and Function of the Heart
Chambers of the Heart
The heart has four chambers: two upper chambers called atria and two lower chambers called ventricles.
-
The right atrium receives oxygen-poor blood from the body and sends it to the right ventricle, which then pumps it to the lungs for oxygenation.
-
The left atrium receives oxygen-rich blood from the lungs and passes it to the left ventricle, which pumps it to the rest of the body.
Heart Valves
The heart has valves that ensure blood flows in one direction and prevent any backflow. These valves play a critical role in the efficiency of blood circulation.
Blood Circulation
The heart circulates blood through a closed system of arteries and veins. This continuous flow supports every cell in the body, ensuring they receive the oxygen and nutrients needed to function properly.
Size and Location
The human heart is about the size of a closed fist and is located in the center of the chest, slightly to the left, nestled between the lungs.
Key Facts About the Heart
-
The heart beats approximately 100,000 times a day.
-
It pumps around 7,500 liters (or about 2,000 gallons) of blood daily.
-
The heart’s rhythmic contractions are what produce the familiar heartbeat sound.
Common Heart Conditions
Heart Disease
