Chapter 2 - Fluid, Electrolyte, and Acid-Base Imbalances Flashcards
aldosterone
a hormone whose main role is to regulate salt and water in the body, thus having an effect on blood pressure
anion
a negatively charged ion
approximate percentage of water weight
an adult is approximately 60% water and an infant is approximately 70% water
ascites
the accumulation of fluid in the peritoneal cavity, causing abdominal swelling
buffer system
The general category name for a variety of systems in the body that help the body to maintain normal blood pH
Each buffer system is made up of two compounds, together referred to as a buffer pair.
capillary permeability
the property or capability of capillary walls to allow the selective flow of substances and cells into and out of the capillary
cardiac dysrhythmia
a problem with the rate or rhythm of your heartbeat caused by changes in your heart’s normal sequence of electrical impulses
carpopedal spasms
frequent and involuntary muscle contractions in the hands and feet
cation
a positively charged ion
cerebrospinal fluid
a clear, colorless body fluid found within the tissue that surrounds the brain and spinal cord of all vertebrates; it acts as a cushion
chloride
an electrolyte that helps the body maintain its fluid balance. It also helps make the digestive enzymes that help the body metabolize food.
dependent area of the body
an area of the body affected by gravity (such as the buttocks)
dependent edema
a term that doctors use to describe gravity-related swelling, found most often in the legs and feet
diabetic ketoacidosis
a serious complication of diabetes that occurs when your body produces high levels of blood acids called ketones
diffusion
the net movement of anything (for example, atoms, ions, molecules, energy) from a region of higher concentration to a region of lower concentration
edema
swelling caused by excess fluid trapped in your body’s tissues
edematous
(adjective) relating to or affected with edema
electrocardiogram
also called ECG: a record or display of a person’s heartbeat
electrocardiography
the process of producing an electrocardiogram
extracellular compartment
the space outside the organism’s cells
extracellular fluid
all body fluid outside the cells of any multicellular organism; it includes intravascular fluid and interstitial fluid
hematocrit
the volume percentage (vol%) of red blood cells (RBC) in blood, measured as part of a blood test; there are other names for the hematocrit, such as: packed cell volume (PCV), volume of packed red cells (VPRC), or erythrocyte volume fraction (EVF)
homeothermic
(adjective) maintaining a relatively constant body temperature that is independent of the temperature of the surrounding environment
hydrostatic pressure
the pressure that any fluid in a confined space exerts (for example, if fluid is in a container, there will be some pressure on the wall of that container)
hypercalcemia
a condition in which the blood has too much calcium
hyperchloremia
an abnormally high level of chloride in your blood
