Blood is what kind of solution?
None
Hypertonic
Isotonic
Hypotonic
The Correct Answer is C
Rationale-Blood is considered an isotonic solution because its solute concentration is similar to that of the cells in the body, allowing for free movement of water across cell membranes without causing a net influx or efflux of water. This isotonic nature is crucial for maintaining cell integrity and function.
Isotonic solutions have the same osmotic pressure as body’s plasma
B-Hypertonic solution like 3% saline have higher osmotic pressure compared to plasma. This type of solutions draw water from the cells causing shrinkage
D-Hypotonic solution like 0.45% saline have lower osmotic pressure as compared to plasma. They cause swelling of cells with eventual damage
