Question

Which of the following is the correct sequence in the development of hypertension?

(A) Systemic vasoconstriction along with sodium and water retention.
(B) Release of renin causes the activation of the RAAS.
(C) Blood pressure increases leading to hypertension.
(D) Angiotensin II produced, and aldosterone is released.
(E) Decreased blood flow to the kidney.
1. A>B−>D−>E−>C
2. E−>B−>D−>A−>C
3. C−>B−>E>D−>A
4. E−>A−>D>B−>C

Answer 1

The correct sequence for the development of hypertension starts with decreased blood flow to the kidneys, activating the renin-angiotensin-aldosterone system, resulting in vasoconstriction and water retention, and finally increasing blood pressure.

Step-by-step explanation:

The correct sequence in the development of hypertension involves several physiological steps beginning with a decrease in blood pressure. This decrease is detected by the kidneys, leading to a series of reactions.

1. Decreased blood flow to the kidney.
2. Release of renin causes the activation of the RAAS.
3. Angiotensin II produced, and aldosterone is released.
4. Systemic vasoconstriction along with sodium and water retention.
5. Blood pressure increases leading to hypertension.

Therefore, the correct sequence is E (Decreased blood flow to the kidney), followed by B (Release of renin), then D (Production of Angiotensin II and release of aldosterone), followed by A (Systemic vasoconstriction and sodium and water retention), and finally C (Increase in blood pressure leading to hypertension).
