Glomerulus

Glomerular (Bowman’s ) capsule
The fluid produced when blood is filtered by the filtration membrane in the glomeruli of the kidneys.
Glomerular filtrate
Consists of the macula densa (cells of the distal convoluted tubule adjacent to the afferent and efferent arteriole) and juxtaglomerular cells (modified cells of the afferent and sometimes efferent arteriole); secretes renin when blood pressure starts to falls.
Juxtaglomerular apparatus (JGA)
