Question
Could you please answer questions with explanations.
Question: The inside of your blood vessels are separated from the interstitial space by membranes that are semi-permeable to water. Just after a salty meal, the osmolarity of your blood plasma increases as solutes are absorbed from the GI tract. 1) What will happen to blood hydrostatic pressure during this time?
A) Blood pressure will increase
B) Blood pressure will decrease
C) There should be no significant change to blood pressure
2) What will happen to blood volume during this time?
A) Blood volume will increase
B) Blood volume will decrease
C) There should be no significant change to blood volume
Explanation / Answer
1. What will happen to blood hydrostatic pressure during this time?
A) Blood pressure will increase
Explanation - The basic reason is Osmosis, Ingesting large amount of salt results in a high sodium concentration in the blood stream. This in turn causes water to enter the blood vessels by Osmosis. More water in the blood means a greater volume of liquid and therefore higher blood pressure.
2. What will happen to blood volume during this time?
A) Blood volume will increase
Explanation - If you have too much salt in blood vessels, that means water is going to enter your circulatory system and increase your blood volume.
As blood vessels have a fixed amount of space to contain blood, increasing blood volume will increase blood pressure
