|
Constricts afferent & efferent arterioles
|
Epinephrine
Norepinephrine Endothelin |
|
|
Constricts efferent arteriole
|
Angiotensin II
|
|
|
Dilates afferent & efferent arterioles
|
Decreased NaCl to the macula densa
Endothelial-derived NO Prostaglandins Bradykinin |
|
|
PTH's effect on Vit. D
|
Activates Vit. D to increase intestinal Ca++ absorption
|
|
|
What accumulates in the serum in Addison's Disease?
|
Adrenal malfunction -> Aldosterone deficiency -> K+ accumulation
|
|
|
Increases in the urine in Addison's Disease
|
Na+
|
|
|
Effect of NSAIDs on GFR
|
Inhibit synthesis of prostaglandins -> prevents arteriole dilation -> cannot dampen the effects of the constrictors
|
|
|
What causes the increase in GFR with high-protein diet and increased blood glucose?
|
When amino acids and glucose are absorbed in the PCT they drag Na+ across -> decrease NaCl reaching the macula densa -> decrease afferent arteriole resistance.
|
|
|
Effect of PCT damage on arteriole tone
|
Increases amount of NaCl reaching the macula densa -> constriction to prevent volume depletion
|
|
|
Accumulates in the body in Conn's Syndrome
|
Adrenal Tumor -> increased aldosterone -> Na+ retention
|
|
|
Increases in the urine in Conn's Syndrome
|
K+
|
|
|
Release triggered by increased atrial filling
|
Atrial natriuretic peptide
|
|
|
Activation triggered by pressure receptors in the aorta and carotid sinuses
|
Sympathetic Nervous System
|
|
|
Effect of Atrial natriuretic peptide
|
Increased Na+ excretion
|
|
|
Effect of sympathetic nervous system on Na+
|
Increased Na+ retention
|
