The <u>proximal convoluted tubule</u> of the nephron allows the selective reabsorption of useful substances like glucose, amino acids, salts, and water into the blood capillaries.
In the nephron, the proximal convoluted tubule is located between the loop of Henle and Bowman's capsule.
It is the key part of the kidney. The most prominent function of this structure is to reabsorb water, sugar molecules, chloride, and sodium ions from the glomerular filtrate.
The reabsorption of fluids takes place when bulk volumes of sugar and water are transported from PCT to the bloodstream.

Question options:
1. Placing a red blood cell in distilled water
2. Placing a red blood cell into an isotonic solution
3. Placing a red blood cell into a hypotonic solution
4. Placing a red blood cell into a hypertonic solution.
5. Placing a red blood cell with a concentration of 0.9% NaCl into a solution of 1.5% NaCl
6. Placing a red blood cell with an ICF concentration of 0.9% NaCl into a solution with 0.1% NaCl.
Answer:
Crenation (shrinking):
-Placing a red blood cell into a hypertonic solution.
-Placing a red blood cell with a concentration of 0.9% NaCl into a solution. of 1.5% NaCl
Hemolysis (swelling):
-Placing a red blood cell in distilled water.
-Placing a red blood cell into a hypotonic solution.
-Placing a red blood cell with an ICF concentration of 0.9% NaCl into a solution with 0.1% NaCl.
No change:
-Placing a red blood cell into an isotonic solution.
Explanation:
Crenation is an osmotic process in which blood cells shrink while placing <u>hypertonic</u> or alkaline solutions. Hemolysis is the destruction of red blood cells in which cells bloat up and may explode while placing in a<u> hypotonic</u> or acidic solution. The blood cells have no change In an <u>isotonic</u> environment because the relative concentrations of solute and water are equal on both sides of the membrane.
Tell the child that it might fell like a pinch, and have someone hold their arm to comfort them, also tell the child that it will be over quick. This will make the child less scared.
