Question

solute concentrations are not only important for red blood cells, but also for the organs of the body, like the brain.
the nutrients for the brain are delivered by the blood vessels. the wall of the blood vessels are semi - permeable membranes that allow free water to move between the blood and the matrix of the brain.
in the image, is the blood hypertonic, isotonic, or hypotonic compared to the matrix of the brain?
hypertonic
isotonic
hypotonic
brain matrix
blood
solute

Explanation:

Observando la imagen, se puede ver que la concentración de solutos es la misma en la sangre y en la matriz cerebral. En una solución isotónica, la concentración de solutos es igual en ambos lados de una membrana semipermeable.

Answer:

Isotonic
