Document Summary
The liver is one of the glands in the digestive system. It has both endocrine and exocrine properties: exocrine: secretes bile, which goes to the gall bladder and then the intestines, endocrine: secreted into the bloodstream. The liver is the largest gland in the body. Portal veins come from various areas including those mentioned above: chylomicrons from the digestive tract come in from the portal veins to be digested, they have a functional circulation rather than a typical nutritional circulation. Hepatic arteries are paired with the portal veins and just run in the opposite direction: they oxygenate the liver. The hepatic vein has a typical nutritional function: it takes carbon dioxide produced in the liver back to the heart, it drains directly into the inferior vena cava. The first is endocrine secretion into the blood stream. Lipids combined with proteins can travel in the aqueous cytoplasm. Cholesterol is necessary for growth of the pm, but it can be bad when.
