Is richly supplied with blood vessels?

∙The alveoli are richly supplied with blood capillaries. Alveoli and capillaries both have very thin walls, which allow the exchange of oxygen and carbon dioxide to take place.

Why is small intestine richly supplied with blood capillaries?

This is called absorption. Absorption is what makes the small intestine such an important part of the digestive system. The small intestine has a rich blood supply so that these nutrients, which have been absorbed by the small intestine, can be carried away.

Which part of the respiratory system is most richly supplied with blood vessels?

The gill consists of branched or feathery tissue richly supplied with blood vessels, especially near the gill surface, facilitating the exchange of oxygen and carbon dioxide with the surrounding water.

Why are alveoli supplied with capillaries Class 7?

Alveoli are covered with blood capillaries so that the exchange of gases can take place between the membranes of the alveoli and the surrounding capillaries. This allows oxygen to diffuse into the blood and carbon dioxide to diffuse out of the blood.

Why does blood vessels 3 join the small intestine to the liver?

The portal vein brings venous blood from the spleen, pancreas, and small intestine so that the liver can process the nutrients and byproducts of food digestion.

Why are there so many blood vessels in the intestines?

The blood supply to the intestines involves three major arteries and many smaller arteries, which fan out throughout the abdominal region. These arteries work together to supply the intestines with a vital supply of oxygenated blood.

What are the lungs richly supplied with?

The walls of the alveoli are supplied with an extensive network of blood vessels. So lungs maximise the area for gaseous exchange through the presence of large number of alveoli which are richly supplied with blood.

What is common between extensive network of blood vessels around walls of alveoli and in glomerulus?

The common thing between the extensive network of blood vessels around the walls of the alveoli and in the glomerulus of nephron is the thin walled capillaries richly supplied with blood.

Are nephrons richly supplied with blood vessels?

Which part of the respiratory system is richly supplied with blood vessels?

What provides access for blood vessels entering and leaving the liver?

The liver is supplied by two main blood vessels on its right lobe: the hepatic artery and the portal vein. The portal vein brings venous blood from the spleen, pancreas, and small intestine so that the liver can process the nutrients and byproducts of food digestion.

Why is the blood in hepatic portal vein deoxygenated?

Your blood supplies oxygen and nutrients to all the tissues of your body. By the time the blood reaches the liver, a lot of its oxygen is gone. Doctors call this deoxygenated blood. The job of the hepatic veins is to move this blood out of your liver.
