©BRAINBARTER 2024/2025 NURB 3150: Antihypertensives (CHP 26) Exam Study Guide. BP Regulation - answerArterial BP: - force exerted on arterial walls by blood flow Response to Hypotension: - SNS is stimulated (increase HR, BP, force of contraction, vasconstriction and renin release) - Adrenal Medulla secretes epi & non-epi (increases BP/HR) - Kidney's retain fluid (causes increase in volume thus increasing BP) Response to HTN: - increase renal secretion - fluid loss decreases circulat...

(in this particular order) - ANS: leukocytes; platelets; erythrocytes what are the major functions of blood? - ANS: - plays a role in immune function - temperature regulation - pH regulation - gas/nutrients/ w...

principal determinants of BP - arterial pressures (CO X peripheral resistances) and Cardiac outputs (heart rate, myocardial contractility, blood volumes and venous returns) life style modifications available to tx hypertension - weight loss, sodium regulations, DASH diets, alcohol restriction, aerobic exercises and smoking cessation consequences of hypertension - myocardial infarction, heart failure and angina development, kidney disease risk, stroke and arterial pressure rising hypertensi...

What is the RAAS system pathway? Ans: Kidney's detect low BP and release renin- which turns into angiotensinogin which is produced by the liver-this leads to angiotensin 1 and this goes to the lungs where angiotensin 1 converting enzyme turns it into angiotensin 2. A2 causes vasoconstriction which helps to increase BP. The angiotensin 2 also affects the brain causing the hypothalamus to stimulate a thirst response by stimulating the secretion of vasopressin (ADH) to help increase water...

What is systolic pressure? Ans: pressure the blood is exerting against the artery walls when the heart beats What is diastolic pressure? Ans: pressure the blood is exerting against the artery walls while the heart is resting between beats What is blood pressure determined by? Ans: volume & viscosity of circulating blood cardiac output: amount of blood pumped ea. min elasticity (compliance) of blood vessels peripheral vascular resistance What is the regulation of BP in nerual? Ans: s...

What is a hormone and how does it act? Hormones are chemical messengers that are responsible for regulation. They are secreted into body fluids, mainly blood. It has specific actions on target tissues, which are any tissue that has specific receptors for that particular hormone. What is a paracrine gland? a secretion that enters interstitial fluid but affects only neighboring cells What is an autocrine gland? A secretion that only affects the secreting cell. What is an en...
