These are the functions:
1. Carries carbon dioxide and oxygen. Carbon dioxide are found in the veins while oxygen are found in the blood that passes in the artery.
2. Carries nutrients to the different tissues and cells of the body.
3. Helps dispose waste materials; the blood carries waste products of metabolism so that the body will be able to dispose of them properly.
4. It helps fight infection, for the WBC that are found in the blood are the ones who eat foreign body and they increase in number if there is an infection.
5. Carries hormones to the different target tissues.
6. Platelets in blood will prevent hemorrhage for they will then gather at the site of the cut or wound and harden or produce a clotting factor thus preventing further blood loss.

M$• Blood flows everywhere through the human body.
• We cannot live without it.
• The heart pumps blood to all our body cells, supplying them with
oxygen and food.
• Blood also carries proteins and cell fragments called platelets that let blood clot where there has been an injury.

Overall, blood performs the following functions:
1. Transports oxygen from the lungs to body tissues and transports the waste products of cellular metabolism and nutrients, hormones and enzymes.
2. Regulates blood clotting, body temperature, acid-base balance, water and electrolytes.
3. Protects against harmful organisms through white cells and antibodies.

Blood performs many important functions within the body including:
*Supply of oxygen to tissues (bound to hemoglobin, which is carried in red cells)
*Supply of nutrients such as glucose, amino acids, and fatty acids (dissolved in the blood or bound to plasma proteins (e.g., blood lipids)
*Removal of waste such as carbon dioxide, urea, and lactic acid
Immunological functions, including circulation of white blood cells, and detection of foreign material by antibodies
*Coagulation, which is one part of the body's self-repair mechanism
*Messenger functions, including the transport of hormones and the signaling of tissue damage
*Regulation of body pH (the normal pH of blood is in the range of 7.35–7.45)3 (covering only 0.1 pH unit)
*Regulation of core body temperature
*Hydraulic functions
