Ch. 19 Long term Control of BP Flashcards
Long term control of BO is related to? And is based on?
maintaining homeostasis of body fluid volume.
Maintaining a balance b/t intake/output of fluid
What is the bodies response to: Increase in extracellular fluid results in increased blood volume and arterial pressure
kidneys excrete excess extracellular fluid and returns the pressure to normal
Determinants of Net Fluid Movement Across the Kidney Capillaries
- > capillary BP
- > Colloid ossmotic pressure
- > Capsular pressure
Glomerular Filtration rate:
Increased renal blood flow: ______
Decreased Plasma Protien: ___
Hemorrhage: _____
Increased GFR inmcreased GFR -> Causes Edema Decreased Cap BF -> Decreased GFR
GFR is regulated by?
Hormonal Reg
Neural Reg
Renal Auto regulation
-> All three mechanism adjust renal blood pressure and resulting blood flow
diuresis is?
The effect of pressure to increase water excretion is called pressure
The effect of pressure to increase Na excretion is called pressure is called
natriuresis
What plays a dominant role in long term pressure control?
Renal Body Fluid System for Arterial Pressure Control
As extracellular fluid volume increases arterial pressure _____
Increases
The increase in arterial pressure causes the kidneys to lose ___ and _____ which returns _____ fluid volume to normal
Na and water
Extracellular
