  • c

    Which receptor is primarily responsible for regulating heart rate?

    a) alpha 1

    b) alpha 2

    c) Beta 1

    d) Beta 2

  • heart; kidneys

    Beta 1 regulates ____ & _____.

  • lungs; blood vessels

    Beta 2 regulates _____ & ______.

  • adipose tissue; bladder

    Beta 3 regulates _____ & ____.

  • activation; inhibition

    Alpha 1 is responsible for ____ while Alpha 2 is responsible for _____.

  • blood vessels, neck of bladder, eye

    Alpha 1 regulates (3)

  • presynaptic nerve terminals

    Alpha 2 regulates

  • increase heart rate & vasoconstriction

    Epinephrine is an agonist of both alpha 1 & beta 1: how will it affect HR and vascular tone?

  • decrease

    Prazosin is an antagonist of alpha 1. What does it do to BP, increase or decrease?

  • decrease

    Clonidine is an agonist of the alpha 2 receptor, how would you expect bp to change, increase or decrease?

  • chronotropy

    -increased heart rate/ heart rate set by SA node

  • inotropy

    -force of contraction

  • dromotrope

    -speed of electrical conduction

  • carotid sinuses; aortic arch

    Where are Baroreceptors found? (2)

  • carotid aortic bodies; ventral surface of medulla

    Where are Chemoreceptors found? (2)

  • c

    Which organ releases Renin?

    a) heart

    b) liver

    d) spleen

  • c

    Which organ releases Angiotensinogen?

    a) adrenal cortex

    b) kidney

    c) liver

    d) hypothalamus

  • ADH

    -a peptide hormone that increases water permeability of the collecting duct; conserves water

  • aldosterone

    - a steroid hormone that increases active reabsorption of Na+ in the collecting duct in response to increase K+ or decreased Na+.

  • osmotic pressure; blood pressure/renin & angiotensin

    ADH is regulated by _______ while Aldosterone is regulated by ______.

  • renin; angiotensin 1

    Angiotensinogen is converted by _____ into ______.

  • ACE; angiotensin 2

    Angiotensin 1 is converted by _____ into ______.

  • d

    Which organ is responsible for producing ACE?

    a) heart

    b) liver

    c) kidney

    d) lungs

  • constrict blood vessels, stimulate adrenal cortex to release aldosterone, stimulate posterior pituitary to release ADH

    What are the three main functions of Angiotensin II?
