-
in the cardiovascular system, diffusion occurs in the:
capillaries
-
very slow and only works over short distances
diffusion
-
steps to Bohr Effect
- 1. tissues use O2
- 2. produce CO2
- 3. lowers pH
- 4. causes a right shift in dissociation curve
- 5. HbO2 gives up O2 more readily
-
Bohr Effect (right shift)*
-
oxygen dissociation left shifted curve
- gives up O2 less at high pO2
- able to take up O2 at lower pressures a lot more easily
- take up more readily at low pO2
-
B cells
B lymphocytes are specialized antigens that produce antibodies (lock and key type) attaches to phagocytize it, interfere with its vital functions and lyse it
-
PO2
partial pressure of oxygen
-
partia pressure of oxygen
.21 at sea level
-
immunization
conferring immunity (through prior exposure)
-
immune
resistance to or protection from disease causing pathogens
-
basis of immunization
resistance to or protection from disease causing pathogens
-
clonal selection
once an antibody recognizes an antigen, the body selectively makes copies of antibody
-
wall effects
slowing of fluid by contact of the fluid with the cells wall
-
circulatory system in amphibian
- very simple gass*
- usually supplemented by skin breathing
- lungs arent good enough to take in O2
- restricted to moist enviroments
-
circulatory system of reptiles, birds, and mammals*
- lungs only
- flow moves across pressure gradients from high to low
- ****
-
circulatory system of fish*
