Water Content of the Body’s Organs and Tissues The body is about 60% water; main sources of water are ingestion and metabolism Fluids consist of water and dissolved substances

Fluid Compartments in the Human Body The intracellular fluid (ICF) is the fluid within cells. The interstitial fluid (IF) is part of the extracellular fluid (ECF) between the cells. Blood plasma is the second part of the ECF. Materials travel between cells and the plasma in capillaries through the IF.

FLUID COMPARTMENTS Intracellular fluid (ICF) – fluid inside the cell About 2/3 of the body’s water is in the ICF High concentration of potassium, phosphate, magnesium, protein Extracellular fluid (ECF) – fluid outside the cell; includes interstitial fluid and blood plasma 1/3 of the body’s water is in the ECF Interstitial fluid (IF) – fluid between cells, not in the vessels Gases, nutrients, and wastes can travel from cells to the capillaries through the IF High concentration of sodium, chloride, bicarbonate; less protein that plasma Plasma – transports, via the vessels, nutrients, gases, wastes, proteins, clotting factors High concentration of sodium, chloride, bicarbonate, proteins

A Pie Graph Showing the Proportion of Total Body Fluid in Each of the Body’s Fluid Compartments Most of the water in the body is intracellular fluid. The second largest volume is the interstitial fluid, which surrounds cells that are not blood cells.

FLUID MOVEMENT BETWEEN COMPARTMENTS Osmosis – passive movement of water from high water concentration to low water concentration Osmotic pressure – pressure exerted due to solute content (mostly Na + ) in the vessels. The ICF and IF have the same osmotic pressure so that cells are in an iso-osmotic environment Hydrostatic pressure – pressure exerted by a fluid against a vessel Colloid osmotic pressure – pressure exerted due to protein content in the vessels (primarily albumin); draws water toward into the circulatory system Water moves toward the higher concentration of protein in the vessels Hydrostatic pressure and colloid osmotic pressure are opposing forces
Image of page 6
Capillary Exchange Net filtration occurs near the arterial end of the capillary since capillary hydrostatic pressure (CHP) is greater than blood colloidal osmotic pressure (BCOP). There is no net movement of fluid near the midpoint of the capillary since CHP = BCOP. Net reabsorption occurs near the venous end of the capillary since BCOP is greater than CHP.

PROBLEMS WITH FLUID BALANCE - EDEMA Edema – build up fluid in the interstitial space Several conditions can cause edema. Some are described below: Weakened heart Less force of contraction in myocardial contractile cells can compromise the movement of blood through the circulatory system

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
