hepatic portal vein.
Blood vessels are the tubes through which blood travels. They include veins, capillaries, and arteries.
Can be veins, can be arteries, can be capillaries, can be the aorta..
Blood vessels - arteries, capillaries and veins.
Nutrients pass through the capillaries (a type of blood vessel) in the small intestine.
Your body digests some and it is picked up when blood runs through capillaries next to the small intestine.
As red blood cells travel through capillaries oxygen is released (disassociated) with hemoglobin. The oxygen then diffuses down it's concentration gradient into the tissues.
Unoxygenated blood travels to the heart though the veins to be pumped to your lung capillaries. At you lung capillaries the blood becomes oxygenated and then goes back to the heart to pump oxygenated blood to the rest of your body. the capillaries blood travels though you arteries.
Blood passes through capillaries as a means of either passing products to the cells or picking up things from the cells. The small intestine is where most digestion takes place so the capillaries pick up digested material to take to the liver via the portal system. The digested fat is picked up by the lymph capillaries, lacteals, which returns to the blood when the lymph connects to the right and left subclavians.
The alveoli of the lungs are surrounded by capillaries. As the blood travels through the capillaries, the red blood cells become oxygenated and give up their load of CO2
Blood does not move faster through the capillaries. Blood flow is slowest in the capillaries.
In the small intestine, the epithelial cells lining the intestinal villi receive oxygen primarily through diffusion from the blood in the capillaries that surround them. These capillaries are part of the mesenteric blood supply, which is rich in oxygenated blood delivered from the superior mesenteric artery. The close proximity of the capillaries to the epithelial cells facilitates the exchange of gases and nutrients. Additionally, the small intestine's extensive surface area enhances this oxygen delivery process.
The small and large intestines. The small intestine contains blood capillaries and lymph vessels.
