Small intestine

1. The honey possum has a long pointed snout, a brush-tipped tongue, reduced jawbones and muscles, and pointed incisors and canines but small peg-like teeth. It also has ridges across the roof of its mouth. Explain how these adaptations relate to the animal’s diet, which is usually a mixture of nectar and pollen. 
 Answer The honey possum’s adaptations relate to its diet because they do not need massive jawbones and muscles to eat the pollen and nectar. Their long pointed snout and brush-tipped…

still suckling from their mothers. The secondary chamber is the rumen. As they grow older, and start eating leaves and shoots, the rumen grows to allow the stomach to be more efficient in breaking down the fibrous material. Unborn giraffes have a small gall bladder that disappears by the time it is born…

up the intestine -- including muscle cells and the cells that line the inside, known as epithelial cells. They were then placed in a scaffold, The results were new, engineered small intestines grew and had all of the cell types found in native intestine. The new organs contained the most essential components of the originals. Using this same technique, the same was done using human tissues grown from stem cells contained in the intestine and the results were the same--a fully functional small…

Pathophysiology: Small Bowel Obstruction The effect of small bowel obstruction is connected to its start and location. The start, location, and length of the intestinal tract nearest to the obstruction and the existence and severity of ischemia. The cause of small bowel obstruction include hernias, adhesions within the abdomen and tumors. The lumen near the obstruction fills with a massive amount of fluid and gas. The obstruction keeps water and electrolytes from properly absorbing. As a…

This tube is called the alimentary canal or gastrointestinal tract. There are three main functions to the digestive system. The first is digestion. Digestion is where food is changed in the mouth, stomach, and intestines by chemical, mechanical and physical actions, so the body can absorb it, second is absorption which is where nutrient material is taken into the bloodstream or lymph and travels to all cells of the body. Elimination is the last functions. This is…

together; it gives them substance and helps them to maintain their shape (Celiac Disease Foundation). Those with Celiac disease have immune systems that create antibodies to attack this gluten protein. As a result, the intestines are inflamed and the villi that line the intestines are damaged. Villi are very important to absorption of nutrients in the digestive tract. This includes fats,…

Bullfrog Dissection Background The American bullfrog, Lithobates catesbeianus, is an amphibian about the size of a teacup.(National Geographic, “American Bullfrog”). This dissection explored the anatomy of a bullfrog that had been pithed. Pithing is a technique used to prevent the frog from experiencing any cruel or unusual pain during the dissection. A pithed frog has had its nervous tissue in its brain severed thus allowing it to maintain normal bodily function during the dissection without…

via facillitated diffusion while in the small intestine. Chylomicrons are absorbed in two ways; they are combined with proteins to creat lipoproteins which are then used to transport cholesterol in the blood and are absorbed into lymph. Dietary vitamins, pentose, sugars, phosphate ions, iron, calcium, and most electrolytes are absorbed in the duodenum and transported across the epithelium and enter the blood.The journey of food through the small intestine takes three to six hours. Most of the…

probiotic bacterium found in the body of mammals. This popularity of this pathogen is probably due to its digestion aiding abilities. Bifidobacterium bifidum is rod shaped and commonly found in the intestines of mammals, including humans. The pathogen is beneficial to the body and can be found in intestines mainly but also, breast milk and the vaginal area. The amount of Bifidobacterium Bifidum in your system can be increased by taking certain probiotics. Bifidobacterium Bifidum is…
