NLN- Anatomy & Physiology Exam
Questions & Answers8
gas exchange in lungs - ANSWERS-capillaries and alveoli
via avleolar membrane
via diffusion
diaphragm - ANSWERS-muscular partition that separates the thoracic cavity from the abdominal
cavity and aids in respiration by moving up and down
cellular respiration - ANSWERS-the metabolic processes whereby certain organisms obtain
energy from organic moelcules
aerobic or anareobic
aerobic respiration - ANSWERS-cellular respiration that uses oxygen, sequentially releasing
energy and storing it in ATP
begins in cytoplasm--ends in mitochondria
anaerobic respiration - ANSWERS-less efficient, produce less ATP
produces lactic acid
fermentation - ANSWERS-anaerobic respiration in yeast--produces ethanol
, Digestion - ANSWERS-Breaking down of nutrients into small, soluable molecules that can be
absorbed into the blood
mechanical digestion - ANSWERS-the physical breakdown of food into smaller pieces (chewing
increases surface area-easier to swallow)
chemical digestion - ANSWERS-the digestion process in which enzymes are used to break foods
into their smaller chemical buiding blocks
hydrolysis - ANSWERS-Breaking down complex molecules by the chemical addition of water
(essential part of chemical digestion)
hydrolases - ANSWERS-Enzymes that carry out digestion by hydrolosis, uses H2O to breakdown
polymers to monomers
alimentary canal - ANSWERS-a long, muscular tube that begins at teh mouth and includes the
mouth, pharynx, esophagus, stomcah, small intestine, large intestine, and anus
accessory organs - ANSWERS-Liver, Gallbladder, Pancreas
amalyse - ANSWERS-saliva contains this enzyme; begins the process of chemical digestion by
breaking down starches
(carbohydrates--glucose)
Covers windpipe while swallowing? - ANSWERS-eppiglotti
peristalsis - ANSWERS-rhythmic muscular contractions that squeeze food through the
esophagus into the stomach
