Study Notes
Functions of Blood
- Gas Exchange: Oxygen is transported from lungs to tissues by erythrocytes; carbon dioxide is carried back to lungs by both erythrocytes and plasma.
- Solute Distribution: Plasma carries nutrients, hormones, waste products, and ions, regulating their concentrations in tissues.
- Immune Functions: Blood serves as a transport medium for leukocytes and immune proteins, allowing them to reach various tissues for defense against pathogens.
- Blood Clotting: Upon vessel injury, platelets and specific proteins aggregate to form clots, crucial for sealing wounds and preventing blood loss.
- Temperature Regulation: Blood dissipates heat produced by metabolic activities, aiding in the maintenance of a stable body temperature.
- Acid-Base Homeostasis: Blood pH is maintained between 7.35 and 7.45 through buffering systems and plasma proteins, ensuring a stable internal environment.
- Blood Pressure Stability: Blood volume is a key determinant of blood pressure, with sufficient blood volume essential to maintain pressure in circulation.
