The pathway of urine drainage from the kidney begins at the ❌, then to the ❌ calyx, the ❌ calyces, the ❌, exits via the ❌ and enters the ❌ to reach the bladder.

Blood enters the kidney in the left or right ❌, which comes from the ❌ artery. From there it branches into the ❌ arteries which branch into the ❌ arteries to travel to the lobes. There it become the ❌ arteries, which lie in the cortex.
❌ arterioles travel into the glomerulus to the ❌ capillaries, and then blood exits in the ❌ arterioles. It then goes into the ❌ capillaries, the interlobar vein, the segmental vein, and exits via the hilum in the right or left renal vein.

The renal corpuscle is the ❌ capillaries and the Bowman's ❌. The Bowman's capsule's parietal layer is ❌ epithelium while its visceral layer are specialised epithelial cells called ❌. Between these layer's is the Bowman's space. It also contains ❌ cells which are regulatory.
The podocytes are part of the filtration barrier and attach to the ❌ that surrounds the glomerular capillaries. They have foot like processes called ❌ and inbetween are the ❌ which small molecules can move through.

The internal urinary sphinctre is at the junction of the ❌. The detrusor muscle which controls it is stimulated by the ❌ and so is under ❌ control.
The external urinary sphinctre is where the urethra passes through the ❌ (pelvic floor). This is ❌ controlled skeletal muscle.
