Gas exchange between air and blood occurs across the walls of what structure? Gas exchange between ISF and the blood occurs in the:

Alveoli Capillaries

100

Which type of surface marker is present on every nucleated cell in your body?

Class I MHC

100

What causes O2 and CO2 diffuse across the capillary beds? 

The partial pressures are different causeing a gradient. High partial pressure to low partial presure.

Consider a husband and wife sharing a bed, with each one having and electric blanket. Their controls become switched. When the husband feels cold, he turns up the control. This warms up his partner, who turns down the control. This chills the husband who turns up his control even more. The process continues. For both the wife and the husband this would be an example of
Positive feedback

Some nutrients are considered “essential” in the diets of certain animals because

they cannot be synthesized by the organism

200

If a molecule of CO2 released into the blood in your left toe travels out of your nose it must pass through all of the following structures EXCEPT the 1. alveolus 2. pulmonary vein 3. trachea 4. right ventricle 5. right atrium

2. pulmonary vein

What is the function of helper T-cells?

They promote B-cell and T-cell activity

200

What cells use MHC II, and what is its function?

Helper T cells use MHC II to identify APC and cause a cell-mediated response.
