The cardiovascular system, also known as the circulatory system, is composed of the heart, blood vessels, and blood. Its primary role is to transport oxygen, nutrients, and hormones to the body's cells and remove waste products like carbon dioxide. The heart pumps blood through arteries, which carry it away from the heart, and veins, which return it to the heart. This circulation is vital for maintaining overall body function and health.
Components of the cardiovascular system
Heart: A muscular organ that pumps blood throughout the body.
Blood vessels: A network of tubes that transport blood. They include arteries, veins, and capillaries.
Blood: The fluid that carries oxygen, nutrients, hormones, and waste products.
How it works
The heart pumps blood, which carries oxygen and nutrients, to all the body's cells via arteries.
In the capillaries, the blood exchanges oxygen and nutrients for carbon dioxide and waste products.
Deoxygenated blood returns to the heart through veins.
The heart then pumps this deoxygenated blood to the lungs to pick up oxygen and release carbon dioxide.
The oxygenated blood returns to the heart, which then pumps it back out to the rest of the body.
The heart's chambers and valves ensure blood flows in the correct direction.
Key functions
Transport: Delivers oxygen and nutrients to tissues and organs.
Waste removal: Carries carbon dioxide and other metabolic wastes away from the body's cells for disposal.
Hormone distribution: Transports hormones from endocrine glands to their target organs.
Immune support: Carries immune cells throughout the body.
Homeostasis: Helps regulate body temperature, fluid balance, and other physiological states.
