Physiology Questions and Answers
2024 Edition.
When the shape of a curve is sigmoidal this indicates what? -
✔️Cooperative binding
Fetal hemoglobin has a higher affinity for Oxygen then maternal hemoglobin. Which
direction will this shift the Oxygen dissociation curve? -
✔️To the left
Oxygen moves from the _____________ to the ________________, which is from
high concentration to low concentration -
✔️Alveoli, pulmonary capillaries
When temperature is increased this ____________ the affinity of hemoglobin for
Oxygen and the curve shifts to the _________. -
✔️decreases; right
With decreased carbon dioxide in the blood, the oxygen dissociation curve would
shift to the left. -
✔️True
In tissues, CO2 will get converted into ___________ through carbonic anhydrase. In
the lungs, the carbonic anhydrase coverts that into _____________ which then
diffuses into the lungs. -
✔️H+ and HCO3-, H2O and CO2
While climbing a 14er, you realize that the urge to breath has increased. What
compound is responsible for driving a circuit to activate LMNs innervating the
diaphragm? -
✔️H+
Chemoreceptors in the periphery that monitor oxygen and carbon dioxide are located
in: -
✔️Carotid body; aortic body
About 70% (most) of the carbon dioxide in the blood is transported as: -
✔️HCO3-
The three major functions of the renal system are: -
✔️Regulate blood pH
Regulate salt and water balance
Remove nitrogenous waste
, Which of the following is the correct order of blood flow through the renal corpuscle?
-
✔️Afferent arteriole, glomerulus, efferent arteriole
The epithelial cells of Boman's capsule are called __________________. -
✔️podocytes
The glomerulus is a tuft of capillaries in the renal compartment and Bowman's
capsule is part of the blood vascular compartment. -
✔️False.
The glomerulus is a tuft of capillaries in the blood vascular compartment.
Bowman's capsule is part of the renal compartment.
Water moves from Bowman's capsule into the glomerular capillaries because the: -
✔️c. osmotic pressure generated by plasma proteins is higher in the capillaries than
in Bowman's capsule
The peritubular capillary is an extension of the efferent arteriole which wraps around
the ______________. -
✔️Proximal convoluted tubule
Urine has a ____________ ion concentration in the cortex of the kidney when it is in
the ____________________________. -
✔️Low, proximal convoluted tubule
In the proximal convoluted tubule water and most ions follow a
___________________ route, meaning they leave the lumen by passing between
the tight junctions of the epithelial cells. -
✔️Paracellular
When Na+, glucose and amino acids move in across the epithelial cells of the
proximal convoluted tubule, they are reabsorbed by the ________________. -
✔️Peritubular capillary
GLUT 2 is a glucose transporter that permits glucose transport by facilitated
diffusion. You would expect to
find this protein in: -
✔️d. basilar membranes of epithelial cells in the proximal convoluted tubule
What is the difference between the conducting and respiratory zones? -
✔️The conducting zone is the respiratory tract leading up to the alveoli. The
respiratory zone is where the gas exchange happens in the alveoli.
What are the functions of the respiratory system? -
✔️Gas exchange with oxygen entering the pulmonary capillaries from the alveoli and
carbon dioxide entering the alveoli from the pulmonary capillaries.
