PHYSIOLOGY digestive system answers
correct.
DIGESTIVE SYSTEM - -digestion: chemical and mechanical breakdown of food
types of digestion - -chemical: breakdown of food particles into small molecules
-mechanical: phy. breakdown of food (ex. mastication/chewing)
process of digestion - mouth: beginning of mechanical break down and beginning of
chemical digestion (amylase)
pharynx
esophagus
stomach: peristalsis and hydrochloric acid & protease
small intestine: absorption and digestion
large intestine: absorption of water
rectum: storage for waste
anus: exit of waste (feces) aka egestion
accessory organs - -liver: production of bile (which goes in the gallbladder)
-gallbladder: bile is stored here; breakdown of fat
-pancreas: storage of digestive enzymes
nutrient, enzymes, result and location - -CARBOHYDRATES:
*enzymes: amylase, sucrase and maltase
*product: glucose
*fr. mouth to the end of the small intestine
-PROTEIN:
*enzymes: proteases
*product: amino acids
*stomach to the small intestine
-LIPIDS:
*enzymes: lipases
*product: fatty acids and glycerol
*small intestine

CIRCULATION SYSTEM: CARDIOVASCULAR AND LYMPHATIC - -circulation: internal
transport of fluid throughout the body; exchange of gases, absorption of nutrients and
disposal of wastes
-circulation consists of 2 paths:
1.cardiovascular
2.lymphatic
CIRCULATION SYS: CARDIOVASCULAR SYS (PATHWAY) - -consists of:
1.heart: 4 chambers - atRia(RECEIVE) & ventricleS(PUMPS OUT)
2.blood vessels
3.blood
cardiovascular pathway - sup/inf. V.C
right atrium
tricuspid valve(atrioventricular)
right ventricle
semilunar valve(pulmonary)
pulmonary arteries (gas exchange)
pulmonary veins (oxygenated blood)
left atrium
mitral valve(bicusid)
left ventricle
aortic seiluar valve
aorta
body
types of pressure - 1.systole: heart contracts = pressure inc.
2.diastole: heart relaxes = pressure dec.
types of circulation(blood) - -coronary: blood to heart
-pulmonary: blood to lungs
-systemic: blood to body
blood - connective tissue made up of variety of cells suspended in a liquid, plasma
% of blood - rbcs, wbs and platelets - 45%
plasma: proteins, ions, horones and gases - 55%
roles of the different components of blood - -rbcs: transportoxygen binded to
hemoglobin through diffusion and they dont have nuclei and mitochondria
-wbcs: less abundant than rbcs and related with immune defenses
-platelets: blood clotting; immune defenses
