Term
|
Definition
| receives blood from the capillaries of the gastrointestinal organs and spleen and delivers it to the sinusoids of the liver. this allows the liver to store and modify nutrients absorbed from the gastrointestinal tract before they are passed into the general circulation. additionally, the blood draining from the spleen (where most aged and defective RBCs are extracted and broken down) is carrying bilirubin that must be removed from the blood and excreted by hepatocytes |
