Body fluid balance

Question 1

Describe the distribution and composition of body fluids.

Answer 1

60% water in males, varies inversely with fat content. 50% in females. 40% located in ICF, 15% in interstitial fluid, 5% in blood plasma.
consists of mainly electrolytes, small amounts of aa’s and glucose

Question 2

Describe the distribution and composition of body fluids.

Answer 2

60% water in males, varies inversely with fat content. 50% in females. 40% located in ICF, 15% in interstitial fluid, 5% in blood plasma.
consists of mainly electrolytes, small amounts of aa’s and glucose

Question 3

Discuss how the composition of body fluids is maintained at a constant level.

Answer 3

ECF maintined by homeostasis, ICF is mainly maintained by mechanisms which the cells possess.

Question 4

Explain how the osmotic pressure of body fluids is determined.

Answer 4

The number of particles per unit volume of fluid not by the mass of the particles

Question 5

Osmolarity units.

Answer 5

osmol/L

Question 6

Describe the effects of water balance disturbances.

Answer 6

Dehydration: water content of plasma and interstitial fluid

Question 7

Explain how the tonicity of solutions is determined.

Answer 7

Relative concentrations of solutes inside vs outside a membrane

Question 8

Discuss the clinical use of IV solutions.

Answer 8

Can be isotonic, hypertonic, or hypotonic depending on what is being treated.

Question 9

Osmolality units.

Answer 9

Osmol/kg
