Ileum Hallow muscular tube‚ mainly to absorb vitamin B12 and bile salts and whatever products of digestion that were not absorbed; terminal portion joining large intestine at the ileocecal valve.

prevent food from clogging these airways. 16. During digestion‚ enzymes such as amylase break chemical bonds between the sugar monomers in starches. Digestive enzymes also break down foods and make the nutrients available to the body. 17. Mechanical digestion includes the muscles of the stomach contracting to mix stomach fluids and food which produces a mixture known as chyme. Chemical digestion includes the production of acids that aid the digestion and absorption of food. 18. In the stomach‚ hydrochloric

Case Study 1: Zachary’s Story Mike Myers A&P Instructor: Dr. Lok 7-26-15 A) If an ulcer starts eroding the mucosa of the GI track absorption would not happen correctly and some of the ingested and secreted products may seep out of the lumen. When the ulcer makes its way through the muscularis mucosa this would create a way for pathogens to enter. He could also loss control of defecation. B) The condition known as peritonitis is when an ulcer eats a hole in the wall of the stomach and

What Are Apocrine Glands? Apocrine glands are located in the skin‚ breasts‚ eyelids‚ and ears. They are a type of exocrine gland‚ which are glands that secrete hormones into a duct. Counterparts of exocrine glands are endocrine glands that secrete their hormones directly into the bloodstream. Certain endocrine glands also release hormones called pancrines that affect only specifically targeted cells very close to where they are released. Examples of endocrine glands are the pituitary gland‚ pancreas

cells to absorbs nutrients -One fungus makes traps for nematode worms while another fungus has sticky knobs to hold them in place while hyphae penetrate into nematode worm’s body with digestive enzyme and extracellular digestion takes place. -Protoza does intracellular digestion by initially absorbing the food using endocytosis or phagocytosis. The plasma membrane surrounds the food and ingests it. Then it moves the compound to lysosome to break it down. - white blood cells also use phagocytosis

Zachary’s Story Unit 6 Case Study 1 AP2630 Rhonda Carter July 27‚ 2015 A. An ulcer starts by eroding the mucosa of the G.I. tract wall. What functions of digestion and/or reabsorption might be lost if this layer is no longer functional? What functions will be compromised if the ulcer eats through the submucosa and then the muscularis? Absorption would not happen correctly some of the ingested and secreted may seep out of the lumen. This also could create a pathway of entry for pathogens
