Exam 1: Chapter 13 Vocab

Question 1

Acidosis

Answer 1

An acid-base inbalance characterized by an increase in H+ concentration (decreased blood pH)

Question 2

Ascites

Answer 2

A type of edema in which fluid accumulates in the 0peritoneal cavity

Question 3

Active Transport

Answer 3

Physiologic pump that moves fluid from an area fo lower concentration to one of higher concentration; an active transport requires ATP for energy

Question 4

Alkalosis

Answer 4

An acid-base inbalance characterized by a reduction in H+ concentration (increased blood pH)

Question 5

Diffusion

Answer 5

The process by which solutes move from an area of higher concentration to one of lower concentration, does not require expenditure of energy

Question 6

Homeostasis

Answer 6

Maintenance of a constant internal equilibrium in a biologic system that involves positive and negative feedback mechanisms

Question 7

Hydrostatic Pressure

Answer 7

The pressure created by teh weight of lfuid against the wall that contains it. In the body, hydrostatic pressure in blodo vessels results from teh weight of the fluid itself adn the force resulting from cardiac co ntraction

Question 8

Hypertonic Solution

Answer 8

A solution with a osmolality higher than that of the serum

Question 9

Hypotonic Solution

Answer 9

A solution with an osmolality lwoer than that of the serum

Question 10

Isotonic Solution

Answer 10

A solution with the same osmolaity as serum and other body fluids

Question 11

Osmolality

Answer 11

The numebr of milliosmoles per kg of solvent;

Question 12

Osmolarity

Answer 12

The numebr of millisomes per liter of solution

Question 13

Osmosis

Answer 13

the process by which fluid moves across a semipermeable membrane from an area of low solute cocnentration to an area of high solute concentration

Question 14

Tonicity

Answer 14

Fluid tension or the effect that osmotic presure of a solution with impermeable solutes exerts on cell size because of water move across the cell of the membrane
