Body fluid - ANS - It is the largest single component of he body
- Flows in arteries, veins, and lymph vessels
-Have 3 compartments that is secreted into
3 specialized compartments for body fluid - ANS - Joints
-Cerebral ventricle
-Intestinal lumen
Functions of body fluid - ANS -Surrounds and permeates the cells
-Lubricant and solvent for metabolic chemical reaction
-Transports oxygen, nutrients, chemical messengers and waste products to their destination
- Important in regulating body temperature
Body fluid abnormalities can occur by? - ANS -Volume, concentration, electrolyte
composition
-result of pathological conditions
Homeostasis - ANS Maintain stable internal environment

Extracellular fluid - ANS All body fluid outside of the cells
(1/3) of total body water
- Vascular compartment
-interstitial compartment
Dense connective tissue and bones
Intracellular fluid - ANS Fluid inside the cells
(2/3 of total body water), rich in K+ and magnesium ions, organic and inorganic phosphates,
and proteins.
- Relatively low in sodium and chloride ions.
Total body weight in men - ANS 60%
Total body weight in women - ANS 50%
Total body water - ANS -Decreases with age
-more body fat means less % of body water
Vascular Compartment - ANS Located in blood vessels
Extracellular
-rich in protien
Interstitial Compartment - ANS Located between cells
Extracellular
-Rich in sodium, chloride, and bicarbonate ions
-relatively low in k+, magnesium, and phosphate ions

Four sub process of fluid homeostasis - ANS Intake,absorption, distribution, excretion
Fluid intake - ANS Entry of fluid into the body by any route
Fluid absorption - ANS Occurs mainly through the GI tract
abnormal: could also occur through prolonged submersion of water or through the lungs in
near drowning
Fluid distribution - ANS Occurs through the vasculature
-transfer to and between other compartments as a result of pressure and concentration
gradients
Fluid excretion - ANS Occurs primary through the urinary tract(2.5L)
could also occur through bowels, lungs, skin
Osmol - ANS unit of osmotic pressure
Osmolality - ANS osmotic pull exerted by all particles per kilogram of water
Osmolarity - ANS Osmotic pull per liter of solution
Normal osmolality - ANS 290 mOsm
Cell Membrane - ANS Primary barreier to the movement of solutes in the body
Pores allow water and small water soluble substances to pass; lipid soluble substances pass
directly through the membrane
Larger proteins can not pass through
