Question

Difference between crystalloid and colloid is of :

• A. particle size
• B. solute size
• C. diffusion through a membrane
• D. none of the above

Answer 1

Answer: (A), (B), (C)

particle size
solute size
diffusion through a membrane

Difference between Crystalloid and Colloid:
1. Colloids contain much larger molecules than crystalloids do.

2. Crystalloid solutions can be stored in room temperature but colloidal solutions cannot be stored in room temperature. They need to be stored in the refrigerator and there is a limited time period for it too.

3. The crystalloid solutions can escape the vascular system and distribute throughout the body but colloids cannot. They are restricted to the vascular system.

So, crystalloid particles are smaller, escape through membrane where as colloidal are larger particles and do not escape through membrane.

Hence, option A, B and C are correct.
