Question

Explain how the nervous and urinary systems interact to increase blood pressure.

Answer 1

nervous system and urinary system interact to increase a blood pressure by long term regulation.

blood pressure is regulated so gets increased when required by these two systems through one of the very important system of the body tha is (RAAS) RENIN - ANGIOTENSIN - ALDOSTERONE - SYSTEM of the body.

In this nervous system and urinary system works together to increase the blood pressure.

when the blood flow is decreased in body , or the sodium chloride delivery is decreased or due to symoathetIc stimuations due to any of these the juxtaglomerular apparatus of the kidney use to release a petide hormome called renin.

1. first the release of peptide hormone renin takes place by the kidney
2. It then converts the angiotensinogen into angiotensin 1 which is turn gets converted into angiotensinozen 2 by the help of ACE ( angiotensin converting enzyme)
3. angiotensin 2 is known for its vasoconstrictor effects it works on the kidneys proximal convulated tubule to increase the sodium reabsoprtion.
4. its then promotes the release of aldosterone.
5. aldosterone is helpful is promoting the salt and water retention by acting on the distal convulated tubule and which in turn increases the electrochemical potential for sodium ions movements.
6. the sodium collection increases in the kidney and so the water excretion is decreased and which increases the blood flow and blood pressure finally.

so this is the process by which these two systems works together and increases the blood pressure.
