Blood is a vital fluid in the circulatory system, comprising red and white blood cells, platelets, and plasma. Red blood cells transport oxygen, white blood cells defend against infections, and platelets aid in clotting.
Plasma, a liquid component, carries nutrients, hormones, and waste products. Blood maintains homeostasis, regulates body temperature, and supports overall health by facilitating oxygen and nutrient distribution while removing metabolic waste.
- Red Blood Cells: Transport oxygen from the lungs to the body tissues, thanks to the hemoglobin they contain.
- White Blood Cells: Cells of the immune system that fight infections and diseases, defending the body against bacteria and viruses.
- Platelets: Cellular fragments that play an essential role in blood clotting. When there is a wound, they form a clot.
- Plasma: It is the liquid component of the blood, transporting nutrients, hormones, and waste throughout the body.
