Kidney Anatomy/ Physiology
Glomerulus
Network of capillaries at the beginning of a nephron. First
stage in the filtering process of the blood (plasma) to produce
urine. Surrounded by cup-like sac, Bowman’s capsule.
Receives blood supply from afferent arteriole of renal
circulation. 20% of blood that passes through glomeruli is
filtered into the nephrons = 180L/ day
Renin
A hormone made in glomeruli, secreted by juxtaglomerular
apparatus, and involved in the control of arterial BP
