Which of the following will occur if the concentration of membrane-impermeable solutes in the intracellular fluid of a cell is h
igher than the concentration in the extracellular fluid? (Check all that apply.) • ____ a. There will be a net movement of water INTO the cell.
• ____ b. There will be a net movement of water OUT OF the cell.
• ____ c. There will be a net movement of solutes INTO the cell.
• ____ d. There will be a net movement of solutes OUT OF the cell.
• ____ e. There will be a net movement of solutes OUT OF the cell and water INTO the cell.
• ____ f. There will be a net movement of solutes INTO the cell and water OUT OF the cell.
Answer: a. There will be a net movement of water INTO the cell.
Explanation: Since the concentration of the solute in the intracellular fluid is higher than its concentration in the extracellular fluid, and because these solutes are impermeable through the membrane, therefore they can not pass through the membrane rather water molecules will move from the extracellular fluid into the intracellular fluid of the cell. This means that there will be movement of water from a region of higher water concentration to a region of lower water concentration through the membrane. This process is known as osmosis. That is there will be movement of solvent particles (water) from a dilute solution (extracellular fluid) to a more concentrated solution (intracellular fluid) through a selectively permeable membrane.
The volume of blood is reduced as the vessels are more narrow due to the contraction, so less blood reaches the respiring tissues, causing the force of blood flow to increase as there is less space for normal blood flow to occur. This means that blood pressure increases.
