- minor Calyx
- Collecting Tubule
- Nephron
- Collecting Duct
- Urethra
- Major Calyx
- Bladder
- Papillary duct
- Renal Pelvis
- Ureters

Answer 1

Answer:

Nephron-- Collecting Tubule-Collecting Duct- Papillary duct- minor Calyx- Major Calyx- Renal Pelvis- Ureters- Bladder- Urethra

Explanation:

Nephron is a basic unit of kidney,in which urine is formed through the process of filtration (it occurs in glomerulus of the nephron). Nephrons are connected with the collecting duct system of the kidney  to a minor calyx. The collecting duct system consists of  connecting tubule, medullary collecting duct  and papillary duct. The whole  collecting duct system has a role in reabsorption and excretion.

Papillary ducts open at minor calyx, later in major calyx. Calyces open in pelvis , which is located inside hilum of kidney. Ureters  travel out of kidney through hilum and pour urine into the urinary bladder. Urethra is a tube with the role to tranport the urine from the bladder when the bladder is full.
