Study Notes
Basic Functions of Blood
- Transports oxygen and carbon dioxide between the lungs and tissues.
- Transports nutrients to various tissues.
- Removes metabolic waste for excretion through kidneys, lungs, skin, and intestines.
- Regulates acid-base balance
- Maintains osmotic balance with oncotic pressure of plasma proteins.
- Regulates core temperature through blood-heating and -cooling.
- Provides immune defense against infections using leukocytes and antibodies.
- Activates coagulation factors to protect against traumatic bleeding.
- Transports various hormones and metabolites.
Composition of Whole Blood
- Plasma: Constitutes 55% of whole blood and acts as a liquid medium.
- Buffy Coat: Contains leukocytes and platelets, which contribute to the remaining 45% of the whole blood volume.
