Fluid Compartments and Body Fluid Regulation
Body fluids Tutorial
Fluids Compartments:
•
What are the different fluid compartments of the body?
•
What is the size of each compartment of the total body fluids?
•
What is the percentage of each compartment of the total body
weight?
•
How are body fluid compartments in a 75 kg man distributed?

Thank you!!
Different fluid compartments of the body, their sizes, distribution, water intake and output sources, composition of body fluids, and the effects of various infusions on ECF, ICF, and cellular size. Learn about the factors regulated to maintain balance among body fluid compartments and understand the importance of ECF volume and osmolarity regulation.
