Which of the following labels corresponds to the collecting duct? B A B Oc D E F G H

Why is it important that individuals calculate their own target heart rate zone when creating an exercise routine and why should that target zone be re-evaluated over time? The action potential of the squid neuron is an example of how membrane potential in cells are used. true or false

someone has profusely bled and her blood pressure dropped what mechanisms in her body will help compensate? select all that apply vasoconstriction increased adh increased heart rate  vasodilation

Could you help me with this question? All info has been provided.

The following medications are used to treat an exacerbation of congestive heart failure.  Each one of them is actually used to counteract mechanisms the body has naturally set in place in response to a drop in blood pressure and presumed drop in tissue perfusion.  For each medication, explain its affect(s) on A, B, and C.  If you feel it has no effect on a particular parameter, then say "no effect".  Specifically for each:  A)  affect on TPR (total peripheral resistance) and how/why it changes it  B)  affect on cardiac output (contractility, heart rate, stroke volume) and how/why it changes it  C)  blood volume/pressure and how/why it changes it  ACEIs (ACE inhibitors) Beta blockers Digoxin Nitrates (nitroglycerin, isosorbide) Diuretics like Lasix

Anatomic relationships to the sector image are orientated so that ______-sided structures such as the RA and RV are seen at the _____ of the image while ______-sided structures such as the LA and LV are seen towards the __________ of the image; ____________ structures such as the apices of both ventricles appear towards the __________ of the image while ____________ structures such as the atria appear towards the _________ of the image.

If epinephrine binds to an alpha1 adrenergic receptor on smooth muscle of a blood vessel, the vessel will_______. If epinephrine binds to a beta2 receptor on smooth muscle of a blood vessel, the vessel will _______.  Question options: A constrict; constricts B constrict; dilates C dilate; constricts D dilate; dilates

During the late phases (plateau) of the action potential of fast myocardium (e.g. ventricle) which is not true of the sodium channel? OA. Defects in inactivation can prolong the action potential and lead to long QT syndrome. OB. It is refractory. OC.A slower inactivation gate keeps the channel shut in response to sustained depolarization. OD. It fires transiently early on in the action potential and is not active during the late plateau. O E. All are true.
