Nutrition Chapter 7 (Jersey College 2024)
Minerals, such as salt, that dissolve in water are called - answerElectolytes
-A substance that flows freely. - Have the ability to conform to the shape of the container that holds them. - answerFluids
functions of electrolytes - answer1)help regulate fluid balance (osmosis)
2)help nerves respond to stimuli (Action Potential)
3)signal our muscles to contract
Liquid portion of blood is called _____ it is a fluid, but it is not the same as water. - answerplasma
Two-thirds, most of our water, of body's fluid is - answerIntracellular fluid
The remaining one-third of body's fluid is called - answerExtracellular fluid
intra - answerwithin, inside
inter - answerbetween
extra - answeroutside
Solute - answerA substance that is dissolved in a solution. (A powder)
Solvent - answerIn a solution, the substance in which the solute dissolves.
(The water)
Potassium in blood is called - answerKalemia
Sodium in blood is called - answerNatrium
extracellular fluid include - answer-Tissue fluid (interstitial fluid)
-Intravascular fluid (plasma) Fluid found between the cells within tissues and organs of the body. - answerTissue fluid
The fluid portion of blood that carries the blood cells - answerPlasma
lean tissue - answer-non-fat body tissue such as muscle, bone, and internal organs
The body fluid composition of tissue varies by - answer-Tissue type
lean tissues (muscle) have higher fluid content than fat tissues
-Gender
males have more lean tissue and therefore more body fluid
-Age
as we get older, we lose water.
HPO4 2- - answer-Phosphorus in form of hydrogen phosphate
K+ - answerPotassium
Na+ - answerSodium
CL- - answerChloride
In intracellular fluid, ___ and ___ are the predominant elestrolytes - answerK+ and HPO4 2-
In extracellular fluid, ___ and ___ predominate. - answerNa+ and CL-
Water follows what? - answersalt
if someone has not water, we will give them ____ - answerElectrolytes
Water is an excellent ____ because it can dissolve many different substances - answersolvent
The dissolved materials, or ____, include ions, carbohydrates, amino acids, vitamins and minerals. - answerSolute
The amount of fluid in the blood is called - answerBlood volume
increased blood volume can cause blood pressure to rise = - answerhypertension
Because water has a ____ capacity, the temperature of our body fluid remains stable - answerhigh heat How sweat cools the body - answerSweating releases heat as the evaporation of water from skin cools the skin and blood
(Heat comes out, cold come in)
amount of fluid = - answer-amount of pressure (more fluid = more pressure)
What protects and lubricate our tissues? - answerFluid
fluid protects the brain and spinal column - answerCerebrospinal
Moderate consumption of beverages with caffeine is - answersafe and potentially healthful
fluid that lubricates around joints - answerSynovial fluid
Digestive secretions allow for - answereasy passage of material
fluid covering the lungs allows friction-free expansion and retraction - answerPleural
Fluids help to: - answer-Carry nutrition
-distribute heat
-Protects and Lubricates
What osmosis? - answermovement of water from an area where solutes are low concentrated to areas where solutes are high concentrated.
______ governs the movement of fluid into and out of cells. - answerOsmosis
action potential - answerthe change in electrical potential associated with the passage of an impulse along the membrane of a muscle cell or nerve cell.
___ Enables our nerves to respond to stimuli - answerElectrolytes
Movement of ___ and ___ across the membranes of nerve cells changes the electrical charge across the membrane. This change in electrical charge carries the nerve impulse along the nerve cell - answer-
sodium (Na+)
-potassium (K+)
Electrolytes signal our muscles to - answercontract
