Bio 322 Final Exam with complete solutions
If Claire has a hematocrit of 24 and a plasma glucose concentration
of 80 mg/dl, how much glucose does she have in her plasma? -
🔹CORRECT ANSWERS ✔✔96 mg
Calculate the amount of K+ in plasma. Assume that the hematocrit
is 50 and that there are 5 L of blood in your patient. The MW of K+
is 35 g/mol. - 🔹CORRECT ANSWERS ✔✔12.5 mmol
During the flu season and during allergy season some physicians
recommend using a nasal rinse. These solutions are made with a
buffer to regulate pH, and are hyper-tonic. Why would rinsing
mucous membranes in your nose help to reduce symptoms like a
runny nose? - 🔹CORRECT ANSWERS ✔✔A hyper-tonic solution
shrinks cells in the nasal membranes and reduce symptoms.
What are the main neurotransmitters for the sympathetic and
parasympathetic nervous systems? - 🔹CORRECT ANSWERS
✔✔Sympathetic = fight or flight = epinephrine. Parasympathetic
=rest and digest = acetylcholine.
,Where is an interstitial cell in males and what does it do? -
🔹CORRECT ANSWERS ✔✔It is located in the wall of the
seminiferous tubule and it secrets testosterone.
What is a nurse cell in males? - 🔹CORRECT ANSWERS ✔✔These
cells surround and support developing spermatocytes in the wall of
the seminiferous tubules.
Where does a spermatozoon develop and how does it leave the
body? - 🔹CORRECT ANSWERS ✔✔Spermatids develop
throughout life in the testes and epididymis. Sperm move through
the ductus deferens (vas deferens), and leave the body via the
urethra.
Isotonic saline contains 150 mM NaCl. What is the concentration of
Na+ and Cl- in this solution? - 🔹CORRECT ANSWERS ✔✔Na+
= 150 mM and Cl- = 150 mM
What is meiosis and mitosis? - 🔹CORRECT ANSWERS
✔✔Meiosis is called a reduction division since it reduces the
, number of chromosomes. It occurs during production of gametes.
Mitosis is part of the process of somatic cell division.
What is the blood testes barrier? - 🔹CORRECT ANSWERS ✔✔It
is formed by nurse cells and it isolates the seminiferous tubules
from the general circulation.
The decline in levels of progesterone and estrogen that accompany
degeneration of the corpus luteum - 🔹CORRECT ANSWERS
✔✔Results in menses or destruction of the functional zone of the
endometrium.
Oocytes - 🔹CORRECT ANSWERS ✔✔Are produced in the ovary
and enter uterine tube via the infundibulum, and implant in the
uterine wall if fertilization occurs.
What statement is correct? - 🔹CORRECT ANSWERS ✔✔1. The
follicular phase of the ovarian cycle overlaps with the luteal phase
of the uterine cycle.
2. The two phases of the uterine cycle include follicular and luteal.
3. The three uterine phases include menses, proliferative, and
