BIO 181 ASU CAPCO EXAM 3 PRACTICE
ASSESSMENT 2026 COMPLETE SOLVED
QUESTIONS AND MODEL RESPONSES
◉ Where do fats in the body play a role in balance between glucose
and glycogen? Fats have stored glycogen in them that can be
converted back to glucose for other cells to use, when our blood
glucose levels are low.
◉ T/F Surfactants is one of the later components made in the fetus
(prior to birth). True
◉ What does carbonic anhydrase do? carbonic anhydrase, aids
in the conversion of carbon dioxide to carbonic acid and bicarbonate
ions. When red blood cells reach the lungs, the same enzyme helps
to convert the bicarbonate ions back to carbon dioxide, which we
breathe out.
◉ T/F Red blood cells carry CO2 back to the lungs. False
◉ T/F The slow flow of blood in the capillaries facilitates the
production of bicarbonates in the blood. True
, ◉ T/F Veins and venueles have valves in them, but arteries and
arterioles do not. True
◉ There are two factors that cause the release of oxygen from
hemoglobin- list them. Drop in pO2 (Partial pressure)
Drop in PH (Bohr effect)
◉ T/F The two circuits in the heart and the cardiovascular system
have the same blood pressure. False
◉ Once inside the circulatory system __________________ is the molecule
that binds oxygen. Hemoglobin
◉ T/F The lungs have increased surface area to increase the
movement of oxygen into the circulatory system. True
◉ When arterial blood pressure falls the body compensates to raise
the blood pressure. Explain this process. 1) kidney releases renin
2) renin activates angiotensin
3) angiotensin causes vessels to constrict
4) arterial pressure rises
◉ To prevent back flow of blood in the heart there are
