Which salts are found in plasma? Give their functions.

(N/A) The plasma contains various inorganic salts,primarily $Na^{+}$,$Ca^{2+}$,$Mg^{2+}$,$HCO_{3}^{-}$,and $Cl^{-}$.
$1$. $Na^{+}$ and $Cl^{-}$: These ions are crucial for maintaining the osmotic pressure of the blood and regulating the water balance in the body.
$2$. $Ca^{2+}$: This ion plays a vital role in blood coagulation (clotting) and muscle contraction.
$3$. $HCO_{3}^{-}$: This ion acts as a buffer,helping to maintain the $pH$ of the blood within a narrow range (approximately $7.4$).
