Blood is a vital bodily fluid that is responsible for transporting nutrients, oxygen, and waste products throughout the body. It is made up of plasma, red blood cells, white blood cells, and platelets. In this article, we will explore the functions of blood, its components, and potential health issues related to blood.
Components of Blood
- Blood is composed of several components, including:
- Plasma: Plasma is the liquid portion of blood that carries nutrients, hormones, and waste products throughout the body.
- Red blood cells: Red blood cells, or erythrocytes, are responsible for carrying oxygen from the lungs to the rest of the body.
- White blood cells: White blood cells, or leukocytes, are responsible for fighting infections and foreign invaders in the body.
- Platelets: Platelets are responsible for blood clotting and the formation of scabs.
