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.
The organ where nutrients are absorbed is Small intestine
They are located in the small intestine and help with absorption of nutrients from digested food. They also increase a cells surface area
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!!
Yes, the epithelial cell from the small intestine is a eukaryotic cell. It contains a nucleus and membrane-bound organelles, e.g. mitochondria and lysosomes.
the cell lining of the small intestine is called villi and are small, finger-like projections that are used to increase surface area.
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
A ciliated epithelial cell is can be found in the esophagus, trachea, or even lining the inner wall of the intestine
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.
Those cells have microvilli, which helps to absorb nutrients from the small intestine.
it is an organ!
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
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.
