What part of the gastrointestinal tract is responsible for 90 percent of nutrient absorption?
The lining of the small intestine is covered with tiny projections with many capillaries. The projections are called villi. Nutrients pass into the capillaries of the villi and then to other organs of the body.
Where are villi present in the human body and what are their functions?
Villi are largely present in the lower digestive tract. Their function is not only to absorb the digested foodstuffs but also they greatly increase the surface area for absorption.
What drains cerebrospinal fluid in to venous blood in the dural sinus?
The Cerebrospinal Fluid is absorbed into the venous blood in the dural sinuses through the arachnoid villi. Arachnoid villi connect the subarachnoid space to the superior sagittal sinus.
What nephron structures are involved with absorption?
The small and large intestines. The small intestine contains blood capillaries and lymph vessels.
What body system is the lacteal found?
The lacteal is found in the small intestine. It serves the purpose of absorbing fats from the gut into the bloodstream.
Why are capillaries and not arteries or veins found in alveoli nephrons and villi?
vessel walls must be thin to allow ease to transfer of molecules to these tissues i had this on a test and i got it right :)
The intestinal villi contain capillaries and lacteals important chemical digestion?
Is it true that intestinal villi contains capillaries and lacteals important for chemical digestion?
Where is the food absorbed in the capillaries?
Villi (Sing. Villus)
What part is the digestive system villi found?
the villi are small finger-like creases on the small and large intestines. they are used to increase the area for absorption.
What is the villi of the intestinal mucosa containing lymphatic capillaries called?
Lacteals.
What part of the human body acts a the visking tubing?
capillaries in the villi
What is the placental barrier made up of?
Chorionic Villi with Fetal capillaries Intervillous Spaces Decidua basalis with maternal capillaries
What are the function of villi?
the villi are tiny finger-like protrusions lining the small intestines. Digested food passes the villi and broken-down food molecules are absorbed through a wall of cells, and into tiny blood vessels inside the villi called capillaries. Nutrient filled blood from the capillaries joins the main bloodstream in veins around the intestines, ready to be used in other parts of the body. Having villi lining the intestines ensures maximum absorption of nutrients through a huge surface area.
What do the alveoli of the lungs the microvilli and villi in the intestine and the gill lamellae in fishes gills have in common?
The microvilli and villi in the intestine increase the absorbent surface where nutrients are transported into the blood. The alveoli in the lungs and gill lamellae bring oxygen in the air and water to the bloodstream,
From the maternal capillaries nutrients diffuse into the capillaries of the chorionic villi and go to the fetus via the?
Umbilical cord or if old enough put on a mirror and snort it

What do blood capillaries absorb?
Capillaries in Villi absorb all other nutrients except fat.
