PAT 201 W10 - final | Questions with 100% Verified
Answers | Latest Update 2026/2027
Question: Baroreceptors
Answer: Stretch-sensitive receptors in the aorta and carotid sinus that adjust HR, SV, and
vessel
tone to maintain BP.
Question: Chemoreceptors
Answer: Receptors that detect changes in O2, CO2, and pH and increase BP by stimulating HR
and vasoconstriction.
Question: Sympathetic Nervous System (SNS)
Answer: Increases BP by raising HR, contractility, and causing vasoconstriction. (fight/flight)
Question: Parasympathetic Nervous System (PNS)
Answer: Lowers BP by decreasing heart rate. (rest/digest)
Question: Renin-Angiotensin-Aldosterone System (RAAS)
Answer: Long-term BP regulator; increases vasoconstriction and blood volume to raise BP.
Question: Antidiuretic Hormone (ADH)
Answer: Hormone that increases water reabsorption, raising blood volume and BP.
Question: Aldosterone
Answer: Aldosterone
Question: Natriuretic Peptides (ANP/BNP/CNP/Urodilatin)
Answer: Hormones that cause vasodilation and promote sodium/water excretion to lower BP.
Question: Primary (Essential) Hypertension
Answer: Most common type caused by genetic and environmental interactions without an
identifiable disease.
