Study Notes
Basic Functions of Blood
- Respiration: Transport of oxygen (O2) from the lungs to tissues and carbon dioxide (CO2) from tissues to the lungs
- Alimentation: Transports absorbed nutrients from the digestive system to tissues
- Removal of Waste: Delivers metabolic waste products from body cells to organs like kidneys, lungs, skin, and intestines for excretion
- Buffering: Regulates acid-base balance in the body
- Osmotic Balance: Maintains the osmolality (concentration of solutes) and oncotic pressure (pressure exerted by plasma proteins) of plasma
- Body Temperature: Plays a role in regulating core body temperature through blood-heating and -cooling mechanisms
- Immunologic: Provides defense against infections through leukocytes (white blood cells) and antibodies
- Coagulation: Protects against traumatic bleeding by using clotting factors (thrombocytes or platelets)
- Transport: Carries hormones and other metabolites throughout the body
Composition of Whole Blood
- Plasma: Constitutes 55% of whole blood and serves as the liquid medium
- Buffy Coat: Contains leukocytes (white blood cells) and platelets, which are responsible for defending the body against infection and clotting the blood, respectively.
Basic Functions of Blood
- Respiration: Transports oxygen (O2) from lungs to tissues and carbon dioxide (CO2) from tissues to lungs.
- Alimentation: Transports absorbed nutrients from the digestive system to tissues.
- Removal of Waste: Carries metabolic waste products to kidneys, lungs, skin, and intestines for excretion.
- Buffering: Plays a crucial role in regulating the acid-base balance of the body's fluids.
- Osmotic Balance: Maintains osmotic pressure and the oncotic pressure of plasma proteins, helping regulate fluid balance within the body.
- Body Temperature: Helps regulate core body temperature by circulating heat to and from different parts of the body.
- Immunologic: Defends against infection through white blood cells (leukocytes) and antibodies.
- Coagulation: Essential for blood clotting, using coagulation factors to protect against traumatic bleeding.
- Transport: Carries hormones, metabolites, and other substances throughout the body.
Composition of Whole Blood
- Whole blood is composed of plasma, leukocytes, and platelets.
- Plasma makes up approximately 55% of whole blood and serves as the liquid medium.
- Buffy Coat: A thin layer between plasma and red blood cells, composed of leukocytes and platelets.
Basic Functions of Blood
