Blood is the unique fluid connective tissue present in our body and it plays a significant role in transporting a wide variety of substances to different parts of the body. The main components of blood include Red blood cells, White blood cells, blood platelets and plasma. Blood is the main component of the human circulatory system, fulfilling many functions such as:
Regulating body temperature.
Regulates the water content of the cells.
Protects against excess blood loss through clotting.
Regulates the pH by interacting with acids and bases.
Involved in the transportation of hormones, nutrition, enzymes, respiratory gases and other molecules to the respective parts of the body.
Answer:
blood is made up of liquid and solids. The liquid part, called plasma, is made of water, salts, and protein. Over half of your blood is plasma. The solid part of your blood contains red blood cells, white blood cells, and platelets. Red blood cells (RBC) deliver oxygen from your lungs to your tissues and organs.
