Complete the following questions regarding your observations of the web of the frog's foot: How did you distinguish arterioles and venules when you observed the vessels in the web of the frog's foot? How did you recognize capillaries in the web? What differences did you note in the rate of blood flow through the arterioles, capillaries, and venules?

What constituents would you expect to be in the blood that enters the liver? The blood that enters the liver through the hepatic portal system would contain nutrients, such as glucose, amino acids, and fatty acids, that were absorbed from the digestive tract. It Show more…

After you eat, blood passing through the GI tract travels through the __________ to a capillary bed in the __________. a. aorta; liver b. hepatic portal vein; liver c. hepatic vein; spleen d. renal arteries; kidneys
The liver has a portal vein as well as a hepatic vein. It also has unique blood vessels called "sinusoids" that function similarly to capillaries. How do these unique structures determine the function of the organ?

Another view of blood circulation You are already aware of the difference between Pulmonary circulation and Systemic circulation. Additionally the Systemic Circuit can be further divided into the Renal Circuit which takes blood through the kidneys and the Hepatic Portal Circuit which takes all the blood which is full of freshly digested food from the intestines directly to the liver. The kidneys constantly cleanse blood, removing nitrogenous wastes, etc. The renal circuit directs blood through the kidneys constantly. The Hepatic Portal Circuit takes blood directly from the intestines to the liver. The liver, an accessory organ of the digestive system, cleanses blood of toxins before it can be sent to other tissues in the body.
