Afferent dilation increases/decreases GFR
Efferent dilation increases/decreases GFR
Afferent dilation increases GFR

MOA of ADH
Vasopressin 2 (V2) receptors –> camp/PKA and aquaporin 2 insertion into luminal membrane
Nephritic syndrome
Glomerular leakage large enough to allow passage of RBCs
Seen hematuria and RBC casts
Somatic control of urethral sphincter
Pudendal nerve
Sympathetic control –> hypogastric nerve
Parasympathetic control –> pelvic nerve
