Unit 2 Lab 4 Flashcards
where are antigens found
on surface of erythrocytes
what do antigens do?
produce an immune response
where are antibodies found
in plasma
what do antibodies do?
inhibit or strop the antigen and its cell
if you have type A blood what antibody do you have?
anti-B antibody
if you have type B blood what antibody do you have?
anti-A antibody
if you have type AB blood what antibody do you have?
none
if you have type O blood what antibody do you have?
both anti-A and anti-B antibodies
what is an Rh antigen?
another surface membrane molecule on erythrocyes
If you are Rh+ what does that mean?
there are Rh antigens on erythrocytes but the blood DOES NOT contain anti-Rh antibodies
if you are Rh- what does that mean?
you don’t have Rh antigen on erythrocyte and blood does not contain anti-Rh antibodies unless person is exposed to Rh antigen
how can a person be exposed to the Rh antigen?
childbirth, blood transfusions, sharing needles
what is RhoGAM?
given before and after delivery to prevent mother from making Rh antibodies
what are some functions of the respiratory system?
- provides for gas exchange and works with the cardiovascular system
- regulates blood pH -contains receptors for sense of smell
- filters air
- produces sounds
- rids the body of some water and heat through expired air
what are the main organs of the respiratory system
- nose
- pharynx
- larynx
- trachea
- bronchi
- lungs
what are the two parts to anatomical distinction?
upper and lower respiratory system
what Is in the upper respiratory system
nose, nasal cavity, pharynx, associated structures
what is in the lower respiratory system
larynx, trachea, bronchi, lungs
what are the two parts to physiological distinction?
the conducting zone and the respiratory zone
what happens in the conduction zone?
- filters, warms, and moistens air
- conducts that air into the lungs
what structures are in the conducting zone?
-nose, nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles, terminal bronchioles
what happens in the respiratory zone?
site of gas exchange
what structures are in the respiratory zone
respiratory bronchioles, alveolar ducts, alveolar sacs, alveoli
what is the function of the nose
warms, humidifies and filters air
