What Are The Two Main Factors That Control Distribution Of Water In The Vascular And Interstitial Compartments Of The Extracellular Fluid?

What is the distribution of water in the major fluid compartments of the body?

Assuming that the total body water is about 60% of their body weight, roughly 2/3 of that, or 40% is intracellular fluid, and the other 1/3 or 20% is extracellular fluid.

This is also known as the 60-40-20 rule..

What is the distribution of water in the major fluid compartments of the body quizlet?

The intracellular compartment contains the most water, then the interstitial fluid, and then the plasma.

Which mechanism is the main regulator of water intake?

ThirstThirst is the primary regulator of water intake. The thirst center is in the hypothalamus of the brain. As the body loses water, the thirst center in the hypothalamus is stimulated, thus causing you to drink. The kidneys are the primary regulator of water output.

How do kidneys regulate fluid level?

The kidneys can adjust the concentration of the urine to reflect the body’s water needs, conserving water if the body is dehydrated or making urine more dilute to expel excess water when necessary. ADH is a hormone that helps the body to retain water by increasing water reabsorption by the kidneys.

What is the approximate osmolarity of the extracellular fluid of the intracellular fluid?

about 300 mOsm14. What is the approximate osmolarity of the extracellular fluid? Of the intracellular fluid? Extracellular fluid has an osmolarity of about 300 mOsm.

What are the 3 fluid compartments?

There are three major fluid compartments; intravascular, interstitial, and intracellular. Fluid movement from the intravascular to interstitial and intracellular compartments occurs in the capillaries.

What are the two extracellular fluid compartments in the body quizlet?

The extracellular fluid compartment can be divided into several subcompartments. The two major ones are interstitial fluid and plasma. Interstitial (in-ter-stish′ăl) fluid occupies the extracellular spaces outside the blood vessels, and plasma (plaz′mă) occupies the extracellular spaces within blood vessels.

What are the two major fluid compartments in the body?

The body’s fluid separates into two main compartments: Intracellular fluid volume (ICFV) and extracellular fluid volume (ECFV). Of the 42L of water found in the body, two-thirds of it is within the intracellular fluid (ICF) space, which equates to 28L.

What is the difference between interstitial fluid and extracellular fluid?

The interstitial fluid (IF) is part of the extracellular fluid (ECF) between the cells. … Extracellular fluid (ECF) surrounds all cells in the body. Extracellular fluid has two primary constituents: the fluid component of the blood (called plasma) and the interstitial fluid (IF) that surrounds all cells not in the blood.
