Exam 11 Flashcards
why are type 1 alveolar cells important
bc they exchange gases in lungs so the lungs can supply body with more oxygen
a patient taking oral anticoagulants would
would not take Vitamin K,
would be more susceptible to internal bleeding,
NOT have decreased platelet aggregation,
be less likely to have a stroke
To make Teflon-covered o-rings for her experiments, one of your TAs covers a rubber o-ring with a white stretchy tape-like material (Teflon). She pinches the center of the o-ring to ensure the Teflon sticks to itself and stays in place. This experimental device is most similar to what
a red blood cell
Carmen is saddened to learn that a friend has hypertension and further saddened to learn that she does not understand the diagnosis. Therefore, Carmen correctly tells her what
that it is often due to a problem with the kidneys,
it leads to lowering of the expiratory reserve volume,
and the cause is often NOT what is treated for in most patients
Hemophilia is a condition in which at least one protein necessary for clot formation is either not produced or does not function properly. If the protein is thrombin, aside from clotting issues, the additional symptoms we would expect to observe
would be elevated levels of fibrinogen and bruising more easily
when the diaphragm is contracted the pressure inside the lungs is _____ and air flows ____ the lungs
decreased and air flows into the lungs
the surface _____ provided by the _____ allows for existence of the tidal volume
surface tension
pleural cavity
A friend has been very tired lately and quite often dizzy. You correctly conclude that he is anemic. A report from his doctor’s office show normal levels of iron, vitamin B12, and erythropoietin. What type of anemia is this
hemolytic
red blood cells are made in the ____ due to erythropoietin made in the _____
made in bone marrow
EPO made in kidney
which of the following are symptoms of kidney failure
increasing iron levels, difficulty adapting to altitude, chronic high BP, and altered viscosity of the blood
During _____ cytosolic calcium levels in the ____ muscle of the diaphragm are _____
expiration,
skeletal muscle,
are decreasing
A sanguivorous alien from the planet Desmodontidae feeds on the blood of its prey. Its saliva has components that limit clotting thereby maximizing the bleeding of its victim, including humans. A correct method by which the saliva could work would what
that it lowers the level of vitamin K, solubilizes fibrin, and contains agonists for nitric oxide
Your friend’s baby was born well ahead of her due date (i.e., arrived early). Unfortunately, the premature bundle of joy is having respiratory complications because why
the rounder type of alveolar cells are not fully developed,
the flatter type of alveolar cells are not able to function properly,
the alveoli are not remaining open
Brutus’ endurance was not lasting sufficiently to the end of games. Being the good Buckeye, Julie used her physiology knowledge to develop a drug to help him. What are correct statements about the drug
it improves his ability to transport CO2,
caused increased endocrine release from the kidney,
is an agonist for receptors in the bone marrow
during the hemostasis process what happens
platelets participate in a positive feedback,
and prostacyclin is released to limit the process
