What else can I help you with?
The small intestine is covered in millions of villi what are villi and what is their job?
Villi are fingerlike projection from a surface and in the intestine they are one cell thick with blood vessels and lacteal. The funciton is to increase the surface area of the intestine and so increasing the ammount of absorption.
Where cell has the largest surface area?
Cells with the largest surface area are typically found in specialized structures like the small intestine. The cells lining the small intestine have microvilli, which greatly increase the surface area for absorption of nutrients. These cells are specifically adapted to maximize their contact with nutrients in the digestive system.
What is the function of Parietal cell?
Parietal cells are found in the lining of the stomach and secrete hydrochloric acid and intrinsic factor. Hydrochloric acid helps with digestion by breaking down food and killing bacteria, while intrinsic factor is important for the absorption of vitamin B12 in the small intestine.
What are folds of the cell membrane on the free surface?
The folds on the free surface of a cell membrane are called microvilli. They increase the surface area of the cell membrane, allowing for greater absorption of nutrients and molecules. Microvilli are commonly found in cells that are involved in absorption, such as in the lining of the small intestine.
Mention two structural features of small intestine which add to the absorptive capacity?
Four features of the small intestine make it efficient at absorption of digested food: 1. The small intestine is LONG- this ensures food remains in the small intestine long enough for the products of digestion to be fully absorbed into the bloodstrem. 2. The Small intestine is HIGHLY FOLDED into villi (s. villus)- This gives a greater surface area for more efficient diffusion of products into the bloodstream. 3. The small intestine has a RICH BLOOD SUPPLY - Each villus has a network of capillaries so that the products of digestion are carried away from the small intestine efficiently. 4. The epithelium of the small intestine in the villi is only ONE CELL THICK - for easier diffusion of the products of digestion into the bloodstream. The walls of the capillaries are only one cell thick as well!!
What cell is cell lining the small intestine?
the cell lining of the small intestine is called villi and are small, finger-like projections that are used to increase surface area.
What is a lining if the small intestine?
the lining of the small intestine has folds, and are covered with finger-like projections called villi, which are covered with thousands of micro-villi
The small intestine is covered in millions of villi what are villi and what is their job?
Villi are fingerlike projection from a surface and in the intestine they are one cell thick with blood vessels and lacteal. The funciton is to increase the surface area of the intestine and so increasing the ammount of absorption.
Why does the cell from the inner lining of the intestine has the folded mebrance?
The inner lining of the intestine has folds in it so as to increase the surface are. This greater aids in the absorption of nutrients from the gut. The larger the surface area, the greater the rate of absorption.
Is the small intestine a cell tissue or organ?
it is an organ!
What is the function of the intestinal cell?
Those cells have microvilli, which helps to absorb nutrients from the small intestine.
Where cell has the largest surface area?
Cells with the largest surface area are typically found in specialized structures like the small intestine. The cells lining the small intestine have microvilli, which greatly increase the surface area for absorption of nutrients. These cells are specifically adapted to maximize their contact with nutrients in the digestive system.
Is ileum a tissue or a cell?
The ileum refers to the last part of the small intestine, and is composed of many cells.
What is the Function of the small cell intestine?
to keep you eating healthy because that is what makes you hungry if there were no cells do you know what would happen we would all be dead yes dead
What is the function of Parietal cell?
Parietal cells are found in the lining of the stomach and secrete hydrochloric acid and intrinsic factor. Hydrochloric acid helps with digestion by breaking down food and killing bacteria, while intrinsic factor is important for the absorption of vitamin B12 in the small intestine.
What is the basic function of a cell?
The basic function of a Mesothelial cell is to act as a lining for body cavities. This type of cell helps seal fluids in these cavities and keep unwanted materials away.
What organ produces nuclease enzymes?
At the centre of a cell ---- ---- ----
