Blood is composed of several different components, including red blood cells, white blood cells, platelets, and plasma.
Red blood cells, also known as erythrocytes, are responsible for carrying oxygen from the lungs to the rest of the body and removing carbon dioxide. They make up the majority of the cells in the blood.
White blood cells, or leukocytes, are part of the body's immune system and help to fight off infections and diseases. There are several different types of white blood cells, each with its own specific function.
Platelets are small cell fragments that help to form blood clots and stop bleeding when a blood vessel is damaged.
Plasma is the liquid component of blood and makes up about 55% of its total volume. It is mostly composed of water, but also contains proteins, electrolytes, hormones, and waste products.
Overall, blood is a complex and vital fluid that plays a crucial role in maintaining the body's overall health and functioning.

They contain hemoglobin, which binds to oxygen and carries it throughout the body. - White blood cells: White blood cells are a type of immune cell that helps to fight infection.
