Answer:
Water retention in tissue cells and intercellular spaces because of osmosis
Water retention in tissue cells and intercellular spaces because of osmosis is the correct answer. Let's understand why this is the case in detail.
Osmotic pressure and isotonic solutions:
- Osmotic pressure is commonly used to determine the molar masses of proteins and polymers.
- Two solutions that have the same osmotic pressure are called isotonic solutions.
- In an isotonic solution, the concentration of solute particles is the same inside and outside the cells.
Osmosis and water movement:
- Osmosis is the movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.
- In the context of the human body, osmosis plays a crucial role in maintaining the balance of fluids inside and outside the cells.
- When a solution is hypertonic (higher solute concentration) compared to the fluid inside the cells, water moves out of the cells, leading to cell shrinkage.
- On the other hand, when a solution is hypotonic (lower solute concentration) compared to the fluid inside the cells, water moves into the cells, causing them to swell.
Effects of excess salt intake:
- Excessive salt intake can lead to an increase in the concentration of solute particles in the extracellular fluid.
- This increased solute concentration in the extracellular fluid creates a hypertonic solution compared to the fluid inside the cells.
- As a result, water moves out of the cells through osmosis, leading to water retention in the tissue cells and intercellular spaces.
- This water retention causes puffiness or swelling of the body.
Other options:
- Option B: Water loss from the cells through skin tissues does not explain the puffiness or swelling experienced by people taking a lot of salt.
- Option C: Capillary action of water through skin pores does not directly relate to the water retention in tissue cells and intercellular spaces.
- Option D: Excessive thirst and drinking more water may help in diluting the extracellular fluid but does not directly explain the water retention and swelling.
Therefore, the correct answer is option A - Water retention in tissue cells and intercellular spaces because of osmosis.
