What are 3 treatments for people who have been exposed to CO?
|
Removal of CO source and administration of supplemental O2, a blood transfusion of blood containing hemoglobin unboud by CO, and hyperbaric oxygen therapy to drive oxygen into the blood.
|

|
How does capillary exchanges keep the composition of interstitial fluid (tissue fluid_) within normal limits?
|
O2>lungs and nutrients from digestive tract>tissues where exchange takes place. Picks up CO2 and other metabolic wastes and transports it away from the tissues to exchange surfaces in the lungs and kidneys
|
|
|
How can CO lead to death?
|
It binds to hemoglobin much better than O2 does
|
|
|
What are antibodies?

When an injury occurs, what does blood clotting involve? why is this function of the blood imporant?
|
fibrinogen (a plasma protein) produced by the liver and platelets, we'd bleed to death otherwise
|
|
|
Why could the liver be responsible for bleeding to death from a scrape b
|
If the liver disease caused fibrinogen to no longer be produced, you could easily bleed to death because fibrinogen is a plasma protein that helps in blood clotting.
|
|
|
What are the 3 main functions of the blood?
|
Primary transport medium
defends the body against invasion by pathogens has regulatory functions |
|
|
How does blood help regulate body temperature?
|
by picking up heat, mostly from active muscles, and transporting it about the body.
|
|
|
What components create osmotic pressure?
|
The salts and plasma proteins in blood to keep the liquid content of blood high
|
|
|
What are a few of the bloods regulatory functions?
|
help regulate body temperature by picking up heat, mostly from active muscles, and transporting it about the body.
|
|
|
What does the blood contain that are chemicals that stabilize the pH, and keep it relatively constant?
|
buffers
