Biology respiratory and digestive terms

how does bile help with the digestion of fats?

bile breaks fat droplets into smaller fat droplets

breathing is regulated by a center in the

brain

what is the role of peptidase

break peptides into amino acids

what is the role of pepsin

break proteins into small polypeptides

the pancreas secretes enzymes and bicarbonate into the

duodenum

which of the following is not a main type of digestive enzyme? enterokinase, lipase, nuclease, carbohydrase, protease

enterokinase

when rib muscled relax

exhalation begins

when you exhale as fully as you can, the extra air is called?

expiratory reserve volume

what is the role of lipase?

fat droplets break into glycerol and fatty acids

the epiglottis is

flap that covers windpipe when eating or drinking

air moves into the lungs when the diaphragm is

flattened down by contraction

digestion is defined as the process whereby

food is chemically and physically broken down

alveoli are

sacs at end of bronchioles

which of the following are absorbed by lacteals

starches

what is the max amount of air that can be forced in our out of the lungs called?

vital capacity

the removal of a large section of the colon is likely to affect the

water balance in the body

bronchus is

tube branching from trachea

the function of the gallbladder is to

store bile

the nutrients in food are broken down by enzymes so that they can be

absorbed

the trachea is

air tube that connects mouth to lungs

4 steps of digestion do not include: absorption, digestion, ingestion or alimentation

alimentation

proteins are made up of long chains of

amino acids

oxygen moves from alveoli to blood because

amount of oxygen in blood is low

the pharynx is

area in throat that is passageway for air and food

what do cells need oxygen for?

cellular respiration

which would you notice the change in in 6 hours? why ham, apple splice, bread, chocolate bar

macromolecules

out of the following which is not a macromolecule? metabolites, nucleic acids, lipids, carbs or proteins?

metabolites

digestion of nutrients start in

mouth

expiration is..

move air out of lungs

lipids act as energy molecules and

part of cell membranes

where in the digestive tract does the chemical digestion of protein begin

stomach

the function of the cardiac sphincter is to prevent back flow of acid chyme from the

stomach to esophagus

during exhalation, what structure does air pass through immediately after leaving the bronchioles?

the bronchi

when a person is breathing normally, the amount of air that is exhaled is called the

tidal volume

most oxygen is carried by the blood bound to hemoglobin. most carbon dioxide is transported by the blood dissolved in blood fluids. T OR F?
