Anatomy & Physiology Mrs. Halkuff
Accessory organs produce secretions that aid the organs of the alimentary canal. Include: Salivary Glands Pancreas Liver Gall Bladder
Located in the mouth 2 types of cells Serous: Produces thin, watery amalyse Mucus: Produces mucus that binds food particles together and lubricates them for swallowing. Amalyse + Mucus = Saliva
Parotid Submandibular Sublingual
Large, elongated gland that lies posterior to the stomach. Belongs to the endocrine & digestive systems. Produces digestive juices that travel from the pancreatic duct to the duodenum. Amalyse: Breaks down carbs. Proteinase: Breaks down proteins. Lipase: Breaks down lipids.
The largest gland in the body. Right side of the body Produces bile to break down fats. Breaks down nutrients & drugs in the blood. Stores iron Produces urea
Pear-shaped sac containing dark green bile. Located on the underside of the liver. Bile travels from the bile duct to the duodenum.
Hormones are produced and released by mucosa cells of the stomach and small intestines. Control Digestion: Gastrin: Causes the stomach to produce digestive acids. Secretin: Stimulates the pancreas and livers bile. CCK: Causes pancreas to release pancreatic juice and the gallbladder to empty. Control Appetite: Ghrelin: Stimulates appetite when theres lack of food in the digestive tract. Peptide YY: Inhibits appetite when the digestive system is full.
Incisors: Used for clipping or cutting off bites of food. 8 teeth front & center of mouth (4T, 4B) Canines: Used for tearing & ripping food. 4 corner teeth (2 T, 2 B) 1 st & 2 nd Premolars (Bicuspids): Used for chewing & grinding food. 8 teeth behind canines (4 t, 4 B) 1 st & 2 nd Molars: Used for chewing & grinding food. 8 teeth behind premolars (4 T, 4 B) 3 rd Molars: Used for chewing & grinding food. Wisdom Teeth 4 teeth behind 3 rd molars (2 T, 2 B)
A tooth has 2 divisions: Crown: White, visible part of tooth above the gumline. Root: Below the gumline and anchors the tooth in place.
Enamel: Hard substance that covers the crown and protects from decay. Dentin: Calcified layer beneath the enamel. Cementum: Covers the root and cements it into place in the jaw bone. Pulp: Center of the tooth that contains blood vessels & nerves.
