1. a. Short term mechanisms for modulating blood force per unit area include modulating what three things?
1. Vessel diameter
3. Heart Rate
B. Long term mechanisms will modulate ____blood volume_______ . 2. Two major arterial baroreceptors are located where?
a. Carotid Sinus
b. Aortic Arch
3. Using up and down pointers. demo the consequence of increased blood force per unit area ( BP ) on the urges sent to the encephalon. the consequence on the parasympathetic ( PNS ) and sympathetic ( SNS ) nervous systems and the ensuing alteration in blood force per unit area.
?BP ? __?__ urges ?__?__ PNS and __? __ SNS ? __? __ BP 4. As a consequence of these alterations in the PNS and SNS. list two effects on the bosom and one on blood vass.
Heart: Decreases cardiac end product and decreases bosom rate.
Blood vass: Vasodilation.
5. Similar to oppugn 3. show the consequence of diminishing blood force per unit area.
?BP ? _? _ impulses ? __? __ PNS and __?___ SNS ? __?___ BP 6. In add-on to effects on the bosom and blood vass. what endocrines were released from the adrenal secretory organ? __Epinephrine_______________________________ and ________norepinephrine_________________________
7. a. What cells in the kidney proctor low blood force per unit area? __Juxtaglomerular_______________ B. What enzyme is released as a consequence of low blood force per unit area? ___Renin__________ c. What does this enzyme act on in the blood? ___Angiotensinogen______________ 8. Name two effects of Angiotensin II.
B. ____increase aldosterone release____________________________ 9. a. The chief consequence of aldosterone is: __To addition Na and H2O resorption in the __kidneys. ___________________________
B. How does this addition blood volume? ___An addition in sodium leads to an addition in H2O which leads to an addition in extracellular fluid and in bend additions blood volume. 10. a. What other endocrine will increase H2O resorption from the kidney? __Antidiuretic Hormone_______________
B. What is the major stimulation for this endocrine? __An addition in plasma osmolarity is the major stimulation for ADH. ____________________
