Question: What two factors directly affect cardiac output?




(a) stroke volume and resistance

(b) stroke volume and heart rate

(c) heart rate and mean arterial pressure

(d) heart rate and total peripheral resistance - CORRECT ANSWER✔✔b- stroke volume and heart
rate

Question: What is heart block? - CORRECT ANSWER✔✔Impaired transmission of impulses from
atrium to ventricle resulting in slower heart rhythms, and pacemaker would be implanted

and less time around hydrogen thus conferring a partial positive charge on the hydrogen.




Question: In what form and in what location(s) do humans store the majority of their
carbohydrates? - CORRECT ANSWER✔✔Humans store their carbohydrates as glycogen in the
liver and in skeletal muscles.




Question: How can the Na+/K+ pump relate to the process of secondary active transport? -
CORRECT ANSWER✔✔The ATP-driven Na+/K+ pump stores energy by creating a steep
concentration gradient for Na+ entry unto the cell. As Na+ diffuses back across the membrane
through a membrane co-transporter protein, it drives glucose against its concentration gradient
into the cell.

Question: What two hormones control bone remodeling? - CORRECT ANSWER✔✔Parathyroid
hormone and calcitonin




Question: The Frank-Starling law of the heart indicates that the stretching of cardiac cells lead
to: - CORRECT ANSWER✔✔Increased contractile force, which increases stroke volume




Question: Explain the negative feedback mechanism that occurs when blood calcium levels
become too low - CORRECT ANSWER✔✔Parathyroid hormone is released and it (1) increases
osteoclast activity activity (2) increases calcium absorption from food (requires vitamin D) , and
(3) increases calcium reabsorption at the kidneys. These three responses cause blood calcium
levels to return to normal.




Question: Phagocytosis and pinocytosis are both specific types of which vesicular transport? -
CORRECT ANSWER✔✔Endocytosis




Question: Depolarization opens more sodium channels, which leads to increased
depolarization, which increases sodium permeability . This is an example of




(a) negative feedback

(b) positive feedback

(c) homeostasis
