3 ways to get water in the body? |
Liquids Solid foods Cell metabolism |
|
|
#1 way to loss water? |
Urine |
|
|
How much water is loss through insensible loss? |
Lungs 400mL Skin 500mL |
|
|
4 ways the body controls water balance? |
Thirst receptor Antidiuretic Hormone (ADH) Aldosterone Atrial natriuretic peptide (ANP) and T-type |
|
|
What does ADH do? |
Stop the body from releasing water |
|
|
If you increase ADH what will happen? |
The body will retain water. |
|
|
What is the function of Aldosterone? |
Increase sodium, thus increasing water levels. |
|
|
ANP and ANT function? |
regulates fluid, sodium, and potassium |
|
|
An increase in ANP and ANT will do what? |
Increase fluid levels. |
|
|
Hydrostatic Pressure More fluid in the vascular space will do? |
High hydrostatic pressure |
|
|
Hydrostatic Pressure Less fluid in the vascular space? |
Low hydrostatic pressure |
|
|
Where does Hydrostatic pressure move fluids? |
Into the interstitial space |
|
|
The atrial system is has what kind of pressure? |
High Hydrostatic pressure |
|
|
Veins system has what kind of pressure? |
Low hydrostatic pressure |
|
|
A very small vein? |
Venule |
|
|
What connects the artery to the vein? |
Capillaries |
|
|
Where does gas exchange take place in the cellular system? |
The capillaries |
|
|
What factor does particles play in water movement? |
The more present the greater the pull of water. |
|
|
What pulls what pushes? |
Osmotic pressure pulls Hydrostatic pressure pushes |
|
|
What is the function of osmotic pressure? |
Move water from low concentration to high concentration. |
|
|
Edema results in _____ capillary hydrostatic pressure. |
increased |
|
|
What are two causes of edema? |
Higher BP Increased blood volume |
|
|
How does plasma proteins effect edema? |
Loss of albumin results in decreased plasma osmotic pressure causing fluids to stay in the ECF. |
|
|
Give a cause for localized edema? |
Obstructed lymphatic circulation |
|
|
Describe lymph edema. |
Excessive fluid and protein not returned to circulation through loss of lymph capillaries |
|
|
A burn will result in what type of edema? |
localized edema |
|
|

Vomiting Diarrhea Excessive sweating Insufficient intake in older adults Too much formula in infants milk |
|
|
Osmotic diuresis may lead to ? |
Diabetic ketoacidosis |
|
|
Explain how diabetic ketoacidosis can lead to cellular dehydration? |
The higher the amount of particles can lead to fluid loss in the ICF causing dehydration. |
|

|
|
2nd spacing term? |
Edema |
|
|
Define 3rd spacing? |
Fluid shifts from blood into a body cavity or tissue and can't return to vascular compartment. |
