How do digested nutrients get in the blood stream?
After food get digested, there are enzymes that break down larger molecules such as proteins and carbohydrates into smaller molecules before it can pass into the blood stream. Mainly in the small intestine, nutrients pass into the blood stream. Depending on the type of "nutrient" that get passed through, some just diffuse through by difference in concentration gradient. Some require active pumps in the lining of the small intestine to pump the "nutrient" into the cell or blood stream. Hope I didn't confuse you too much. In short, some molecule just pass through. Some needs to be pumped across the cell membrane.
Where does excess cerebrospinal fluid go?
Excess cerebrospinal fluid is usually absorbed by the bloodstream through a system of channels called arachnoid villi. These villi allow the fluid to be reabsorbed back into the circulatory system, maintaining the balance of fluid within the brain and spinal cord.
How do osmosis and villi play a role in feeding cells the glucose they need?
Osmosis occurs in the small intestines which contain the villi. There are blood vessels connected to the villi so nutrients/glucose in the small intestines diffuses through the semi-permeable membrane of the cells in the blood vessel.
True nutrients are absorbed into the bloodstream through villi into the large intestine?
The Bronchus in the lungs provide a larger area for Oxygen and Carbon Dioxide to transfer into and out of the blood stream
Why is the surface of the placenta covered in villi?
The villi on the surface of the placenta increase the surface area available for nutrient and gas exchange between the mother and fetus through the blood vessels. This increased surface area helps ensure efficient transfer of oxygen and nutrients to the fetus and removes waste products from the fetal circulation.
How does the composition of blood changes as it flows through the villi?
The blood flow in through the villi changes in an increase as the intestine near the villi is wide to go through.
What drains cerebrospinal fluid in to venous blood in the dural sinus?
Cerebrospinal fluid is drained into venous blood in the dural sinuses through structures called arachnoid granulations (also known as arachnoid villi or pacchionian bodies). These specialized projections of the arachnoid mater penetrate through the dura mater into the superior sagittal sinus and other dural sinuses, where they allow for the reabsorption of cerebrospinal fluid into the bloodstream.
What is the function of blood vessels in villi?
The nutrients that are absorbed through the villi are transfered to the blood stream where it can be transfered to other parts of the body. So the vessels enable the villi to transfer nutrients to the blood system. = 0
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.
Nutrients in the small intestine enter the bloodstream by passing through?
some one help me
Do Nutrient molecules pass from the small intestine into the blood stream through the villi?
Yes.
How does nutrients enter your blood stream?
through cells in the villi of the small intestine
What does villi do in the human body?
Villi are small, finger-like projections in the small intestine that increase the surface area for nutrient absorption. They contain capillaries and lacteals to help absorb and transport nutrients into the bloodstream.
What were does the nutrients go to after going through villi?
Villi are finger-like projections on the lining of the small intestine. After digestion is finished off, the nutrients and digested food goes to the villi, then from the villi to blood capillaries. Blood capillaries are small blood vessels that contain tiny holes through with tissue fluid leaks out. Then, the nutrients go from the blood capillaries to the tissue fluid. The tissue fluid is mainly water, it surrounds the tissues in our body and it forms a continuous link between the blood plasma (liquid part of the blood that helps the blood to circulate) and the cells. After going to the tissue fluid, the nutrients go to the blood plasma and then to the cells where it is used up (oxygen and chemicals from our food is separated from waste materials and carbon dioxide) Arteries carry oxygen from the blood cells to the body cells and veins carry carbon dioxide. After going to the cells, the nutrients go to the tissues. Hope this helped. I was also confused first but then my teacher explained it to me. :)
How is the blood that leaves the villi different from the blood that enters them?
Villi in the intestinal tract absorb nutrients from food matter passing by them and "gives" those nutrients to the blood entering them. Therefore, blood exiting the villi have much more nutrients, vitamins, minerals, etc. than blood entering them.
What function reabsorbs cerebral spinal fluid back into the blood?
The function that reabsorbs cerebral spinal fluid back into the blood is called arachnoid villi or arachnoid granulations. These structures are responsible for draining CSF from the subarachnoid space into the bloodstream, helping to maintain the fluid balance in the brain.
Where does digested food move into the blood?
In villi
