the alveoli are covered by

small aggregates of lymphatic tissue found in the mucosa of the ileum.

carries blood that is oxygen poor but rich in absorbed nutrients and other substances form digestive tract

longest part (3.5 m long) it absorbs any final nutrients, with major absorptive products being vitamin B12 and bile acids.

the ____ which contains pulp which consist of blood vessels

area artificially enlarged for illustrative purposes

wave of smooth muscle relaxation moves ahead of the bolus, allowing the digestive tract to expand.

the lips and cheeks are important in the process of mastification. the tounge is a large muscular organ that occupies most of the oral cavity.

produce saliva and regulated primarily by Autonomic nervous system with parasympathetic stimulation.

degrade DNA and RNA into nucleotides.

contains mucin that is stimulated by sympathetic

inactive form is pepsinogen breaks covalent bond of proteins to form smaller peptide chains chief cells

the childhood teeth is called

It extends from ileocecal junction to the anus. Chyme is converted into feces.

composed of acinar glands. Acini cells produce digestive enzymes that empties into the pancreatic duct.

small pouches of the peritoneum filled with fat

proximal end of the large intestines where it joins the small intestine in the ileocecal junction.

are saccules in the colon that give it its segmented appearance.

connects the greater curvature of the stomach to the transverse colon and posterior body wall

strong contractions

the soft palage is elevated, closing off the nasopharynx

0.5-1.5 L daily

the pharynx consist of 3 parts:

lipid digesting enzyme

complex alkaline solutions that contain bile salts, bile pigments, cholesterol, lipids, lipid soluble hormone, and lecithin( mixture of phospholipids).

how many teeth in adult

the breakdown of large organic molecules into smaller molecules. the addition of liquid, enzymes and mucus to the ingested food

Removal of the undigested material such as fiber from food, and other waste products from the body as feces

the last 2-3 cm of digestive tract. Begins at the inferior end of rectum and ends at the anal canal.

small pouches of the peritoneum filled with fat and situated along the colon and upper part of the rectum

Movement of molecules out of the digestive tract into the blood or lymphatic system.

Serous membrane that lines the Peritoneal cavity

a muscular hollow organ which temporarily stores ingested food and continue to process of mechanical digestion.

The major protein digesting enzyme (PROTEOLYTIC) are

pancreatic islets, or islets of Langerhans that produce the hormone insulin and glucagon.

described as a C-shaped located below the stomach that surrounds the pancreas

located below the mandible. Produce more serous than mucous secretions

serous gland located just anterior to each ear. Parotid ducts enter the oral cavity through the 2nd upper molar

how many teeth in childhood

anterior part that contains the bone

teach is held in place within pockets in the bone

A wave of contraction of the smooth muscle behind the bolus propels it through the digestive tract.

moist stratified squamous epithelium, that extends from the pharynx to the stomach. It is approx. 25 cm long and lies anterior to the vertebrae and posterior to the trachea.

binds with vit b12 and makes its more readily absorbed in the small intestine produced by parietal cells

composed of both endocrine and exocrine tissues

retroperitoneal and posterior to the stomach

General term referring to serous membranes attached to the abdominal organs.

connects the mouth to the esophagus.

Consumption of solid or liquid food through the mouth

the movement of food form one end of the digestive tract to the other. mixing is the movement of food back and forth in the digestive tract

kills microorganism and activates the enzyme, pepsin (produced by parietal cells)

in which food is crushed and mixed with saliva to form a bolus for swallowing Increases efficiency of digestion

weak contractions

the teeth of an adult is called

The liver produce and secretes about

(1)keeps oral cavity moist (2) protective functions (lysozyme antibacterial enzyme, neutralizes mouth ph (3)begins the process of digestion – 5 % of total carbohydrates.
