25 . C low blood pressure and secrete renin
Juxtaglomerular cells in distal convoluted tube helps in filteration rate of glomerulus
Decrease in blood pressure causes renin to secrete and maintain blood pressure
25. The juxtaglomerular cells sense a. low blood pressure in the carotid body and activate renin-angiotensin-aldosterone....
Drugs that block the renin-angiotensin-aldosterone system lower blood pressure by constricting arteries. increasing excretion of water. constricting veins. increasing excretion of potassium.
12. Both ADH and aldosterone act to a. increase urine volume. b. increase blood volume C. increase total peripheral resistance. d. produce all of these effects 13. Blood pressure is lowest in a. arteries b. arterioles C. capillaries d. venules e. veins 14. Angiotensin 11 a. stimulates vasoconstriction b. stimulates the adrenal cortex to secrete aldosterone. C. inhibits the action of bradykinin. d. does all of these 15. Stretch receptors in the aortic arch and carotid sinus a stimulate secretion...
D Question 18 1 pts Which statement is true about the renin-angiotensin-aldosterone system (RAAS). RAAS is a mechanism that increases blood volume in response to increased renal perfusion RAAS is a mechanism that regulates arterial blood pressure. RAAS is a mechanism that decreases blood pressure. RAAS is a mechanism with detrimental effects that decrease workload for the left ventricle.
Activation of the Renin-Angiotensin System in response to a decrease in blood pressure stimulates the release of vasopressin from the posterior pituitary which produces an increase in water reabsorption but not an increase in plasma volume. Is this true or false? Why?
The mechanisms regulating sodium and water balance help maintain blood pressure homeostasis. These mechanisms include the renin-angiotensin II mechanism, neural regulation, and ADH. Drag each item to the appropriate category. Keep in mind relationships may be direct or indirect. Categories are Angiotensin II. Sympathetic Nervous System, or both a. stimulates ADH release b. stimulates renin release c. stimuates aldosterone release d. increases sodium uptake e. increases water reabsorption f. stimulates vasoconstriction g. increases peripheral resistance h. stimulated by baroreceptors in...
Renin is secreted by ____ in response to ___ concentration of sodium ions in blood a) adrenal cortex... low b) the hypothalamus .. low c) granular cells.. low d) granular cells.. high e) the macula densa.. low
Compre hewsion. 1. List the order of events to restore low blood pressure to normal. Use the list below. This substance acts as a vasoconstrictor and stimulate aldosterone a. Rennin is released and converts angiotensinogen to angiotensin I b. Angiotensin I is converted into angiotensin II c. Decrease in blood pressure or sympathetic nerves stimulate juztaglomerular cells d. Under influence of this hormone, Na' and H,O reabsorption occurs e. Increased blood volume raises blood pressure f. 2. Joyce, an accident...
What is the reason for a low blood pressure, despite always having high blood pressure (HTN), and high cholesterol? A) Blood vessels have become bigger, so there is less pressure on the wall and less pressure overall. B) At this time, the heart muscles are not contracting correctly because there is tissue death and therefore, less blood is being pumped out of the ventricles to the body. C) Blood vessels have dilated to have more perfusion to his organs.
27. Which of the following statements is most accurate statement regarding the role kidneys play in heart failure? a. They believe there isn't enough fluid volume in the body, deactivate RAAS, and increase blood volume and pressure. b. They believe there isn't enough fluid volume in the body, activate RAAS, and decrease blood volume and pressure. c. They believe there isn't enough fluid volume in the body, deactivate RAAS, and decrease blood volume and pressure. d. They believe there isn't...

Choose the best answer 1. As filtrate moves through the mammals, it generally undergoes a dramatic decrease in osmolarity. A. Distal convoluted tubule B. Bowman's capsule C) Descending segment of the loop of Henle D. Proximal convoluted tubule E. Ascending segment of the loop of Henle 2. If a person is taking a drug that completely inhibits angiotensin-converting enzyme (ACE), what will happen to aldosterone secretion when the person goes on a low sodium diet?...
