Answer:

Capillaries are generally arranged in networks called capillary beds. The blood that passes through the capillaries of the small intestine flows through the hepatic portal vein. This arrangement allows the blood to pick up glucose and other substances absorbed from the gut and deliver them to the liver.

In the small intestine,

 

  • Glucose is absorbed by cotransport. Hence, the concentration of glucose at the venous end would be more than at the arterial end.
  • pO2 or partial pressure of oxygen would be high at the arterial end as compared to the venous end.
  • pCO2 or partial pressure of carbon dioxide would be low at the arterial end as compared to the venous end.
  • Hydrostatic pressure and osmotic pressure would decrease from the arterial to the venous end because substances or fluids need to be pushed out as well as absorbed into the capillaries.
