IB SEHS TEST EVALUATION QUESTIONS AND
ANSWERS SET A+
✔✔Stroke Volume - ✔✔Amount of blood pumped by each ventricle in each contraction.
✔✔Basal Heart Rate - ✔✔Minimum Heart Rate
✔✔Venous Return - ✔✔Amount of blood returning back to the heart
✔✔Diastolic - ✔✔The period of time when the heart refills with blood after contraction
✔✔Chemical Digestion - ✔✔Occurs in the mouth, stomach, and small intestine
✔✔Mechanical Digestion - ✔✔occurs in the mouth and stomach (peristalsis in the
digestive tract could also count for this)
✔✔Chyme - ✔✔a pulpy fluid in the stomach (mixture of hydrochloric acid and partially
broken down food)
✔✔Digestive Track - ✔✔mouth, epiglottis, esophagus, stomach, small intestine, large
intestine, rectum, anus
✔✔Rugae - ✔✔The folds or ridges in the stomach and small intestine (expand to
accommodate for extra space)
✔✔Mucosa - ✔✔The mucus like lining of the digestive track
✔✔Villi - ✔✔Small tentacle like things that increase the surface area of the small
intestine to allow for more enzyme action
✔✔Organs that secrete juices - ✔✔Stomach, small intestine, liver, and pancreas
✔✔Liver - ✔✔Produces bile and stores glycogen
, ✔✔Pancreas - ✔✔Secretes digestive enzymes and the hormone that triggers the
release of insulin and glucagon
✔✔Metabolism - ✔✔Set of chemical reactions that occur in living organisms in order to
maintain life.
✔✔Regulation of "energy" - ✔✔High glucose levels--->hormones--->Insulin---
>enzymes--->conversion of glucose to glycogen--->into cells (out of blood)--->(When
glucose levels are low) glucagon--->hormones--->enzymes--->breakdown of glycogen
to glucose via hydrolyse
✔✔Glucagon - ✔✔Peptide hormone produced by the pancreas which raises blood
glucose levels. Causes stored glycogen to be converted into glucose and then releases
the glucose into the bloodstream.
✔✔Insulin - ✔✔Hormone produced by the pancreas that lowers blood glucose levels by
converting glucose into glucagon and storing it in the liver.
✔✔Glycogenolysis - ✔✔The breakdown of glycogen to glucose
✔✔Lipolysis - ✔✔The breakdown of fat stored in fat cells
✔✔tidal volume (TV) - ✔✔volume of air breathed in and out in any one breath
✔✔expiratory reserve volume - ✔✔volume of air in excess of tidal volume that can be
exhaled forcibly
✔✔inspiratory reserve volume - ✔✔additional inspired air over and above tidal volume
✔✔residual volume - ✔✔volume of air still contained in the lungs after a maximal
exhalation
✔✔larynx - ✔✔connects the pharynx (chamber) to the trachea (pipe to the lungs), also
referred to as the voice box with the epiglottis as a cover
✔✔nose - ✔✔provides an airway for respiration, lined with hairs and mucus to take out
smaller and larger particles of dirt and dust
✔✔mouth - ✔✔a main airway for respiration, also used for mechanical digestion,
contains teeth
✔✔trachea - ✔✔the windpipe, connects to lungs, upper part of this is referred to as the
larynx or voice box
