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 organ produces nuclease enzymes?

Why is intracellular digestion unsuitable?
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!!
Is our Small intestine an organ?
It's an organ. The organ system it belongs to is the digestive system, and it is made up of several types of tissues (epithelial, muscle, etc.), so it can't be a system or tissue in itself.
What is the absorptive surface area of the small intestine?
The absorptive surface area of the small intestine is actually about 250 square meters (almost 2,700 square feet) – the size of a tennis court! How is this possible? The small intestine has three features which allow it to have such a huge absorptive surface area packed into a relatively small space:1. Mucosal folds: The inner surface of the small intestine is not flat, but thrown into circular folds. This not only increases the surface area, but helps regulate the flow of digested food through your intestine.2. Villi: The folds form numerous tiny projections which stick out into the open space inside your small intestine (or lumen), and are covered with cells that help absorb nutrients from the food that passes through.3. Microvilli: The cells on the villi are packed full of tiny hair like structures called microvilli. This helps increase the surface of each individual cell, meaning that each cell can absorb more nutrients.
What cell lines the small intestine assembles fats?
Smooth Endoplasmic Reticulum (organelles) cells are responsible for absorption, synthesis, and transport of fats (in intestinal cells). They catalyze reactions involved in these processes.
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.
Is the small intestine a cell tissue or organ?
it is an organ!
What assembles protein in a cell?
the ribsomes
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 organ produces nuclease enzymes?

What inside the cell nucleus assembles ribosomes?
nucleoli
What is one way that the small intestine is modified to increase the surface area for digestoin and absorption?
The cell surface which lines the intestines have villi and microvilli. These are finger-like protrusions which increase the surface vastly.
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
What is Cellular work is carried out by?
The different types of molecules that the cell assembles
What represents the correct pathway of the nutrients in an apple after you take a bite?
Digestive System-Circulatory System-Cell
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!!
