What are the components of blood?

Blood is made up of four main components: plasma, red blood cells, white blood cells, and platelets. Each component performs a specific function in the body.

Plasma is the yellowish liquid part of blood that transports nutrients, hormones, proteins, and waste materials.

Red blood cells (RBCs) contain hemoglobin and are responsible for carrying oxygen from the lungs to body tissues and transporting carbon dioxide back to the lungs.

White blood cells (WBCs) help protect the body against infections and diseases by fighting harmful microorganisms.

Platelets are small cell fragments that help in blood clotting and prevent excessive bleeding when injuries occur.

Together, these components maintain circulation, immunity, and overall body functioning.
