These tiny projections are villi.
Villi are the thin walls in the small intestine that help food particles pass through by absorbing nutrients into the bloodstream. These tiny finger-like projections increase the surface area of the intestine for efficient absorption of nutrients.
Absorption of nutrients primarily occurs in the small intestine, specifically in the villi. The villi are finger-like projections that line the walls of the small intestine and help increase the surface area for absorption. Nutrients are absorbed into the bloodstream through the villi to be distributed throughout the body.
The Bronchus in the lungs provide a larger area for Oxygen and Carbon Dioxide to transfer into and out of the blood stream
it goes trough the bloodstream
absorption
Food molecules are primarily absorbed into the bloodstream in the small intestine. The inner lining of the small intestine is covered in finger-like projections called villi, which increase the surface area available for absorption. Nutrients from food pass through the walls of the small intestine and into the bloodstream, where they are transported to cells throughout the body.
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.
intestine called villi. Villi increase the surface area for absorption of nutrients like vitamins, minerals, and other essential compounds. From the villi, nutrients pass into tiny blood vessels called capillaries and then enter the bloodstream, where they are transported throughout the body to support various functions.
Nutrients enter the blood primarily through the small intestine. After food is broken down in the stomach, nutrients are absorbed through the lining of the small intestine and into the bloodstream. From there, the blood carries these nutrients to different parts of the body where they are used for energy and growth.
bloodstream through the walls of the small intestine. Here, nutrients are absorbed into the bloodstream and transported to cells throughout the body where they are used for various metabolic functions. Any remaining waste is passed out of the body through the large intestine.
Nutrients are absorbed into the bloodstream through the lining of the small intestine. This process involves breaking down food into smaller molecules, which are then transported across the intestinal wall and into the bloodstream for distribution to the rest of the body.
In a perch, food is primarily digested in the stomach and intestine. The nutrients released during digestion are then absorbed into the bloodstream through the walls of the intestine.
