pancreatic juice
-found in duodenum
-hydrolyzes carbohydrates, proteins, and lipids
-optimum pH 8
-contains bicarboonate buffer which neutralizes acid chyme from the stomach
normal blood glucose levels
after meals: 130-150
too much insulin is produced so glucose levels drop to very low levels
low insulin levels cause high glucose levels to return to normal slowly
Type I diabetes
not enough insulin is produced
Type II diabetes
insulin is produced but the body does not respond to it so glucose levels remain relatively the same
what gases control respiratory rate and how?
CO2 and O2. an increase in CO2 or decrease in O2 is detected by chemoreceptors which stimulate the inspiratory center to increase breathing rate.
What does breathing into a bad, hyperventilating, breath holding, and exercise do to the amount of CO2 in the body and how do these changes affect respiratory rates?
Breathing into a bag and exercise increase breathing rate which increases carbon dioxide levels. hyperevntilating decreases breathing rate and decreases CO2 levels. as CO2 decreases, the ability to hold your breath increases
Expiratory reserve volume
breathe normally a few times and after normal expiration, exhale as much as possible
Vital capacity
breathe deeply a few times and and after inhaling as much as possible, exhale everything from lungs
inspiratory reserve volume
(tidal + expiratory) - vital
What are the components that blood seperates into when centrifuged?
top half-plasma
thin layer in the middle- WBC + platelets
bottom half-RBC
% of whole blood that is compised of RBC
Type A blood
RBC clump together in "a"
Type B blood
RBC clump together in "b"
Type O Blood
No clumping
