Orthostatic changes in hemodynamics Flashcard Deck - 10 Cards

Flashcard 1: Arteriolar resistance is regulated by the _____ nervous system

Answer: sympathetic

Flashcard 2: How does increased efferent sympathetic firing (e.g. baroreceptor reflex) affect TPR?_____

Answer: Increased TPR (via increased arteriolar vasoconstriction)

Flashcard 3: The _____ is a fast, neurally mediated mechanism of regulating arterial pressure

Answer: baroreceptor reflex

Flashcard 4: What effect may adenosine have on blood pressure?_____

Answer: Decreased (hypotension)

Flashcard 5: Vasodilation (e.g., following antihypertensive therapy) reduces _____-load

Answer: after

Flashcard 6: What type of receptor acts as a pressure sensor?_____

Answer: Baroreceptor

Flashcard 7: How does increased efferent sympathetic firing (e.g. baroreceptor reflex) affect venoconstriction?_____

Answer: Increased venoconstriction

Flashcard 8: What is the major factor determining blood flow to resting skeletal muscle?

Answer: Sympathetic innervation (α1 receptors)

Extra: At rest, skeletal muscle blood flow is primarily controlled by **sympathetic innervation** (extrinsic control). During exercise, blood flow is dominated by **local metabolic factors** (intrinsic control/autoregulation) such as lactate, adenosine, and K+.

Flashcard 9: The rate at which blood is pumped from either ventricle is called the _____

Answer: cardiac output

Flashcard 10: Both ADH and oxytocin are neuropeptides, synthesized in hypothalamic neurons and secreted from nerve terminals in the _____
