Intestinal Cell 1 ● The small intestine is the part of the digestive tube connecting the stomach to the large intestine. It is an elastic and soft tube made of muscles and membranes, tightly folded in the abdominal cavity.

Intestinal Cell 2 “ ● The intestine's walls are thin, but they are folded, so that their surface is large. ● The folds on the surface have small folds on their surface, to increasing the absorption surface. ● This allows the body to absorb as many nutrients as possible from the food that passes through the intestine.

Location “ - The small intestine is the longest organ in our body, and it is where the most important part of digestion takes place. - Intestine cell is locate in intestine and small intestine cell is stay on villi. - Small Intestine cell help to absorb nutrient and role digest.

Shape of the intestine cell - It is a half oval and at the top of the cell have a villi that the shape look like circular fold.

Circular fold ‘are large valvularflaps projecting into thelumen of the small intestine. ’ Its function is to slow the passage of the food along the intestines, and afford an increased surface for absorption.

Structure & Function of organelle - Circular fold (villi) - Villi and Microvilli (special organelle) - mitochondria - Cell membrane/plasma membrane - Golgi Apparatus - Nucleolus - Rough ER, Smooth ER

Villi and Microvilli (special organelle) Villi and microvilli are responsible for the “brush border” appearance of the lumen of the small intestine. Microvilli also contain enzymes to help in digestion.

Mitochondria produce the energy currency of the cell, through respiration, and to regulate cellular metabolism.

Golgi Apparatus modifying, sorting and packaging of proteins for secretion and also transport of lipids around the cell, and the creation of lysosomes.

Nucleus The nucleus is an organelle found in the center of a cell that serves In nucleus to control the cell's function. It’s contains the majority of the cell's genetic material ex. DNA

Rough ER has ribosomes attached to its surface. Itsis an organelle that produces proteins and helps them fold properly.

oles Centri -The main function of the centriole is to create spindle while process of divided cell in animal cell.

Beneficial bacteria & others part - The blue one is good bacteria (same as when you eat lactobacillus), it help to catch bad bacteria and help to digest sometimes. - It help to support the digestive process to break down food. Produces vitamins, short chain fatty acids and proteins. - The purple part (Pathogens)pathogens are agents that cause diseases or illnesses, include all types of organisms

Function of intestine cell ◎ It absorb helpful substance and pass it through to blood vessel, then it go to various body cell. ◎ providing a barrier against harmful substances. Compare to other cell ◎ The organelle inside the intestine epithelial cell has the same as animal cell, but it has some things different. ◎ The different is microvilli and shape.

Disease - Inflammatory bowel disease (IBD) is a group of inflammatory conditions of the colon and small intestine. Crohn's disease and ulcerative colitis are the principal types of inflammatory bowel disease. - This disease is a medical term that describes a group of conditions in which the intestines become inflamed (red and swollen). Two major types of IBD are

Symptom’s symptoms can range from soft to serious For example: 1. 2. 3. 4. 5. Severe or chronic abdominal pain. Diarrhea, often bloody. weight loss. Lack of appetite. Rectal bleeding.

Causes The exact cause of inflammatory bowel disease remains unknown. They can’t solve it yet, Previously, diet and stress were suspected, but now doctors know that these factors cause worsen but don't cause IBD.

Treatment - They have 3 steps, each step is depend on how serious the disease is.
