Exam 3

dominant method of carbon dioxide transport

point where the trachea divides into right and left primary bronchi is a ridge called

accessory organs stores bile

pancreatic enzymes acts on glycogen and starches

function of smooth muscle layer of the digestive system

primary gas exchange site

composed of prominent lymphatic nodules that function in the immune response

portion of the peritoneum drapes over the transverse colon and coils of the small intestine

deciduous molars are replaced by

heaviest gland of the body

processes is the primary function of the mouth

pancreatic enzyme acts on peptide bonds

primary function of villi

prevents food or water from entering the trachea

mouth and tooth are lined with

structure regulates the flow of material into the colon

direction of diffusion of gases at capillaries near systemic cells

layer functions by secreting a lubricating fluid

portion of the peritoneumattaches the liver to the anterior abdominal wall and diaphragm

not a primary function of the large intestine

brunner's gland

accessory organs produces a fluid to soften food

pitch is controlled by

conducting zone

passageway for air, food and water

lungs and chest wall expand easily

hormone function to counteract the effect of gastric acid in the small intestine

principle bile pigment

cells of the aveoli that produces surfactine

hormone is stimulated by high levels of dietary fat in the small intestine

forms the exchange surfaces of the alveolus

layer of the GI tract is composed of areolar connective tissue that binds the mucosa to the muscularis

opening to the pharynx from the mouth

capability of the gi tract to move material along its length

contains skeletal muscle

small intestine cells secrete lysozyme

pancreatic enzyme that digest lipids

located anterior to esophagus and carries air to bronchi

maintains open airways in the lower respiratory system

cell secretes the hormone that promotes production of hydrochloric acid

structure of the stomach allows greater distension for food storage

conducting airways with the air that does not undergo respiratory exchange are known as

digestive acid, produced by the stomach, begins digestion by denaturing proteins

accessory organs produces a fluid that functions to emulsify dietary fats

direction of diffusion of gases at the alveoli of the lungs

secrete hydrochloric acid

not part of the upper respiratory system
