Question

Write RAS sastem ? (Human anatomy and physiology)​

Answer 1

Answer:

The renin–angiotensin system (RAS), or renin–angiotensin–aldosterone system (RAAS), is a hormone system that regulates blood pressure and fluid and electrolyte balance, as well as systemic vascular resistance. ... This increases the volume of extracellular fluid in the body, which also increases blood pressure.

Answer 2

• ❒ Let the two digits be x and y respectively. The number is (10x + y). After, reversing the digits obtained number is (10y + x).

⠀⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━⠀⠀⠀⠀⠀⠀⠀⠀

$\underline{\boldsymbol{According\: to \:the\: Question :}}$

• The sum of the digits of two digit number is 12.

$:\implies\sf x + y = 12 \qquad\bigg\lgroup\bf Equation (I)\bigg\rgroup$

$\sf{ \frac{31} {\frac{21 \times \textit{x}}{21 \times \beta}} \times{20} + 1 - 0}$

⠀

Now,

⠀⠀⠀⠀

$:\implies\sf 10y + x - 10x - y = 54 \\\\\\:\implies\sf 9y - 9x = 54 \\\\\\:\implies\sf y - x = \cancel\dfrac{54}{9}\\\\\\:\implies\sf y - x = 6\\\\\\:\implies\sf y = 6 + x$

⠀

$\underline{\bf{\dag} \:\mathfrak{From\: equation (I)\: :}}$

⠀

⠀⠀⠀

$:\implies\sf x + y = 12 \\\\\\:\implies\sf x + 6 + x = 12 \qquad\bigg\lgroup\bf y = 6 + x \bigg\rgroup \\\\\\:\implies\sf 2x + 6 = 12\\\\\\:\implies\sf 2x = 12 - 6\\\\\\:\implies\sf 2x = 6\\\\\\:\implies\sf x = \cancel\dfrac{6\:^{3}}{2}\\\\\\:\implies{\underline{\boxed{\sf{\pink{ x = 3}}}}}$

⠀⠀⠀

$\underline{\bf{\dag} \:\mathfrak{Substituting \; value \: of \: x \: :}}$

⠀⠀⠀⠀

⠀

⠀Therefore,

⠀

$\implies\sf y = 6 + x \\\\\\:\implies\sf y = 6 + 3\\\\\\:\implies{\underline{\boxed{\sf{\pink{y = 9}}}}}$

⠀

$\therefore{\underline{\sf{Hence, \; the \: original \; number \; is \; \bf{ 39}}}}$
