It's too bad that you have not put the descriptions and the functions, but I will anyway explain to you the role of each one so that you can answer the question for yourself.
The urinary system consists of the kidneys, ureters, bladder, urethra and urinary meatus. It is formed and begins to function before birth. When the bladder contains 250 mL of urine, the urge to urinate is felt.
The kidney, in the urinary system, has a secretory function (filtration of blood in the glomeruli) and excretory from the pyelon, origin of the ureter.
The ureters are an extension of the kidneys. Their role is to collect urine in the pelvis.
The bladder collects the urine that reaches it through the ureters. Its capacity is about 300 to 600 ml. Urine is evacuated from the urethra during urination.
The urethra is the canal that goes from the bladder to the urinary meatus serving the flow of urine.
Muscular ducts that connect the kidneys and bladder.
Transports urine by peristaltic action from the kidney to the bladder.
Hollow, saclike organ connected to the kidneys.
Narrow duct that connects to the bladder.
Transports urine from the bladder to outside of the body.
Kidneys : helps in forming urine
Ureter : They are connected to kidney and by peristaltic action transports urine from kidneys to bladder .
Urinary bladder : It is an hollow sac that holds the urine .
Urethra : transports urine from the bladder to outside of the body .
The human excretory system consists of : Kidney ,ureter ,urinary bladder and urethra .The figure is shown below .
Now , as far as functions are concerned we have :
Kidneys : They have excretory units called nephrons that further consist of :Bowman's capsulePCT (Proximal convoluted tubule )DCT (Distal convoluted tubule)CT (collecting tubule )
In nephrons urine is formed and via ureter it is transported to a hollow sac like structure called urinary bladder .
This bladder has muscles that cant remain contracted up to longer period )and then voluntary and involuntary it is excreted through urethra .
The process of passing urine is called Micturition .
the kidneys are connected to the urinary bladder by the Ureter
hope this helped pls mark brainliest if possible :)
Urinary bladder - a. Holds urine.
b. hollow sac-like organ connected to the kidneys.
Ureter - a. muscular ducts that connect the kidneys and bladder.
b. narrow duct that connects with the bladder.
c. Transports urine by peristaltic action from the kidney to bladder.
Urethra - a.transports urine from bladder to outside of the body.
Hope it helps.
