Terms in this set (50)
An individual that has tested positive (+) for covid19 but is asymptomatic (no symptoms) will
not transmit the virus to others.
In anatomical position, the left lung consists of two (s) lobes and the cardiac notch.
The Heimlich maneuver is a procedure in which residual air in the alveoli/lungs is used to
expel a piece of food that may be obstructing airflow through the trachea.
The right and left main bronchioles are the actual sites of gas exchange within the lungs.
The alveoli are located between the pharynx and the larynx within the respiratory system.
Antibodies are not capable of directly destroying an antigen themselves. They require the
assistance or binding of other biological products after forming an antigen-antibody complex.
A decrease in the rate and depth of respiration may be the result of hypercapnia or an
elevation in the concentration of carbon dioxide in the blood.
Fever is a component of the inflammatory response which can potentially denature proteins.
With all types of vaccines, the body is left with a population of memory T-lymphocytes for the corona virus.
T-lymphocytes are responsible for recognizing self and nonself cells in the body.
Labored or difficulty in breathing is termed "apnea".
The visceral pleura lines the external lung surface.
B-lymphocytes are associated with the cell-mediated division of the immune system,
responding primarily to viral antigens in the body.
The lymph nodes are the only lymphoid organs which do not directly fight antigens.
When an individual becomes classified as an "AIDS patient" they are now showing the
symptomatic effects of the HIV antigen.
During the exhalation process, the goal is to ____ the thoracic and intrapulmonary volume.
B lymphocytes become immunocompetent in the __.
Which of the choices below is not correct regarding the Pfizer and Moderna vaccines?
The Pfizer and Moderna vaccines have an efficacy (effectiveness) of approximately 80-85%
The histological tissue(s) which makes up a part of the trachea includes which of these?
Ciliated columnar cells
Among the organs and systems of the body that are particularly susceptible to the corona virus are the heart, kidneys, GI tract, and respiratory system. What is it that they all have in common which makes them prone to non-homeostasis from the virus? (according to your notes and study guide)
They all have an abundance of ACE2 and ACE2 receptors within them
In the anatomy of the lymph nodes, there are more afferent vessels feeding in to the node compared to the number of vessels draining the node. What is the physiological reason for this, if any?
It will allow for more time for the fluid to be filtered and cleansed inside the node before
it is drained and sent on its way
The primary "antibody" mediated mechanism which triggers cell lysis and amplifies the inflammatory response is known as ....
The mechanics of "inhalation" depends on which of the following events to occur?
A negative (-) intrapulmonary pressure relative to the atmospheric pressure
Which of the following choices is not listed in your notes as a site where we would expect to find superficial lymph nodes?
For the corona virus to enter into a host cell for replication, it uses this process below.
The spike (corona) portion of the virus attaches to Angiotensin Converting Enzyme (ACE) 2 and then ACE2 receptors for entry
The destructive nature of the Human Immunodeficiency Virus (HIV) is in binding to and the progressive loss of which particular cell?
Which is the best definition or description of Convalescent Plasma?
This is plasma containing antibodies taken from patients that have had covid19, and given to
patients being treated for an ongoing infection
Gas exchange between the lungs and the blood vessels is the process known as....
The first encounter between an antigen and a naïve immunocompetent lymphocyte is .....
The actual site of gas exchange (O2 & CO2) into and out of the vascular system occurs within which anatomical structure(s) of the respiratory system?
Which "T cell" can lead to antibody production from the humoral or antibody producing division of the immune system?
T helper (TH)
The primary difference between cancer-infiltrated lymph nodes and those diagnosed as being Buboes, is which of your choices below?
Cancer-infiltrated nodes are not tender or painful
The center for respiration which determines the rate of breathing and stimulates the muscles involved in inspiration resides in the ....
Medulla of the Brain
It is primarily the concentration of which gas that regulates the rate and depth of respiration through the respiratory center in the brainstem.
Carbon Dioxide (CO2)
A common function of all components and divisions of our immune system is to enhance....
Oxygen and carbon dioxide are exchanged in the lungs and through all cell membranes by ____.
Which of the following types of tissue transplants is "most" likely to be rejected by the immune system of the recipient?
A premature baby's lungs are generally developed well enough to survive by the ___ of gestation
Complement, is a biochemical product which is a part of which line(s) of defense in our immune systems.
B & C (2nd & 3rd)
Select the correct statement about lymphocytes.
B cells produce and secrete antibodies into the blood.
We stated in class, that without these cells there would eventually be no immune system.
Which of the following is considered a "primary lymphoid organ" in the body?
The tonsils which are also referred to as the "adenoids" are the ____.
Blocks modification of the ACE2 receptors and inhibits them from becoming functional
Steroid often given in combination with other drugs to prevent over amplification of the
Anti-viral drug that inhibits viral replication through early termination of viral transcription.
Originally an anti-malarial drug that can prevent the binding of the corona virus to ACE2 receptors
This antibody binds to MAST cells & Basophils during allergic responses to increase the release
Which antibody crosses the placental barrier to confer immune protection from mother to the
embryo/fetus during the gestational term.
We have an antibody that is typically found in the sweat secretions on the surface of the skin
and in saliva. Which is it?
