During osmosis across a capillary wall, if the blood has a higher solute concentration than the surrounding matrix, which way will free water molecules move?
A
From the blood to the matrix
B
Equally in both directions
C
From the matrix to the blood
D
There will be no net movement of water
Verified step by step guidance1
Understand the concept of osmosis: Osmosis is the movement of water molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.
Identify the solute concentration in the problem: The blood has a higher solute concentration compared to the surrounding matrix.
Determine the direction of water movement: Since water moves toward the area with higher solute concentration, free water molecules will move from the matrix (lower solute concentration) to the blood (higher solute concentration).
Consider the semipermeable nature of the capillary wall: The capillary wall allows water molecules to pass through but restricts the movement of solutes, facilitating osmosis.
Conclude the net movement: Based on the principles of osmosis, the net movement of water will be from the matrix to the blood due to the difference in solute concentration.
