The heart is a vital organ that pumps blood throughout the body, supplying oxygen and nutrients to tissues and organs.
What is the Function of the Heart?
The heart's primary functions include:
- Pumping blood: The heart contracts and relaxes to pump blood through the circulatory system.
- Oxygenation: The heart delivers oxygenated blood to the body's tissues.
- Nutrient delivery: The heart transports nutrients from the digestive system to the body's cells.
- Waste removal: The heart helps remove waste products from the body.
How Does the Heart Work?
The heart works through:
- Contraction and relaxation: The heart muscle contracts and relaxes to pump blood.
- Electrical conduction: The heart's electrical system regulates heartbeat.
- Valves: Heart valves ensure blood flows in one direction.
- Chambers: The heart's four chambers (left and right atria, ventricles) facilitate blood flow.
