CIRCULATORY SYSTEM
CIRCULATORY SYSTEM
The body system that is responsible for oxygen and nutrient transport to every cell of the body. Moreover, it is also responsible for removing carbon dioxide and other wastes from the cells.
PARTS of the CIRCULATORY SYSTEM
BLOOD CELLS
BLOOD CELLS
Red blood cells (RBC) / Erythrocytes - are mainly involved in transporting oxygen, nutrients, and other substances to various parts of the body. These blood cells also remove waste from the body.
White blood cells (WBC) / Leukocytes - are specialized cells, which function as a body’s defense system. They provide immunity by fending off pathogens and harmful microorganisms.
Platelets / Thrombocytes - are cells that help to form clots and stop bleeding. They act on the site of an injury or a wound.
BLOOD VESSELS
Arteries - are blood vessels that transport oxygenated blood from the heart to various parts of the body. They are thick, elastic and are divided into a small network of blood vessels called capillaries.
Veins - are blood vessels that carry deoxygenated blood towards the heart from various parts of the body. They are thin, elastic and are present closer to the surface of the skin.
