Study Notes
Functions of Blood
- Transports oxygen from the lungs to cells and carbon dioxide from cells back to the lungs.
- Delivers essential nutrients and hormones throughout the body.
Excretory Function of Blood
- Blood aids in the removal of waste products from metabolism.
- Transports waste to excretory organs like the kidneys for filtration and excretion.
Homeostasis Maintenance
- The body primarily maintains homeostasis through feedback mechanisms.
- Blood plays a crucial role in regulating temperature, pH levels, and fluid balance.
Nutrient Transport Post-Absorption
- Most nutrients absorbed from food travel to the liver via the hepatic portal vein.
- The liver processes, stores, and distributes nutrients to other parts of the body.
Role of Blood in Respiratory Function
- Blood carries oxygen from the lungs to tissues and organs.
- Facilitates the transport of carbon dioxide from cells to the lungs for exhalation.
