If someone runs a marathon through a desert while eating pretzels and not drinking water, their plasma osmolarity: a) rises and becomes hypertonic to the interstitial and intracellular fluid compartments. b) rises and becomes hypotonic to the interstitial and intracellular fluid compartments. c) decreases and becomes hypertonic to the interstitial and intracellular fluid compartments. d) decreases and becomes hypotonic to the interstitial and intracellular fluid compartments.

Respuesta :

Answer:

a) rises and becomes hypertonic to the interstitial and intracellular fluid compartments.

Explanation:

The plasma osmolarity of a human body is the determination of the balance of electrolytes in the body as well as the balance of water present in the body.

The weather conditions in the desert is very high causing the temperature to be very hot. When a person runs in the desert they tend to sweat and lose water and when they eat pretezels without drinking water, they became seriously thirsty and very dehydrated.

This causes the plasma osmolarity of their body to increase and becomes hypertonic to the interstitial and intracellular fluid compartments. This causes the body cells to shrink or reduce in size and they lose water( in humans , they begin to sweat).

Answer: The correct answer to the question is option A

RISES AND BECOMES HYPERTONIC TO THE INTERSTITIAL AND INTRACELLULAR FLUID COMPARTMENTS.

Explanation: Pretzels is a type of snack that is baked in a signature moulded form.

It contains quite alot minerals but most especially sodium because of its high salt content.

The intracellular fluid is the fluid that is found inside the cell and it is sorrounded by plasma membranes while interstitial fluid is the fluid that sorrounds all the cells that are not in the blood.

Marathon race is a long one that requires alot of energy and endurance, without taking water,the body's electrolyte-water balance is meant to reduce but because of the intake of pretzels which is high in sodium, sodium being water loving will make the body's electrolyte-water balance to rise and attain an osmotic pressure rate that is higher than the interstitial and intracellular fluid compartments thereby helping to regulate and supplement the water, endurance and energy loss due to the marathon.
