What is the function of the bladder?
The bladder is the organ that holds urine until it is ready to be released and then helps to expel it from the body. Ureters bring urine to the bladder from the kidneys, passing through an opening to the bladder called the ureterovesical junction. As the bladder fills with urine, nerves send signals to the central nervous system.
Could sperm get into the male bladder?
When the bladder sphincter does not work correctly, the bladder may not close completely, which can cause ejaculate to travel into the bladder rather than coming out of the penis. Most men ejaculate more than 1.5 milliliters (ml) of semen. Men with retrograde ejaculation may ejaculate nothing at all.
What does the ureter do in the male reproductive system?
What does the ureter do in the male reproductive system? It transports and stores sperm cells that are produced in the testes. It also is the job of the epididymis to bring the sperm to maturity, since the sperm that emerge from the testes are immature and incapable of fertilization.

What is the role of LH in testosterone production?
FSH is needed for the production of sperm (spermatogenesis), and LH stimulates the production of testosterone in the testicles. Testosterone plays a role in the development of many male traits, such as muscle strength and mass, bone mass, distribution of fat, and sex drive.

How many ml of urine does the bladder hold?
The bladder is lined by layers of muscle tissue that stretch to hold urine. The normal capacity of the bladder is 400-600 mL. During urination, the bladder muscles squeeze, and two sphincters (valves) open to allow urine to flow out. Urine exits the bladder into the urethra, which carries urine out of the body.

What system filters blood?
The urinary system filters all blood that passes through it. All parts of the blood, except the blood cells themselves are emptied into the kidneys. The kidney then picks out things that it wants to keep, like glucose and proteins. It’s a strange way to clean the blood. It’s sort of like cleaning the fridge by taking everything out first.

What are the layers of the bladder?
The urinary bladder consists of different layers of tissue: 1 Mucosa layer forms the innermost layer lining the hollow organ. The mucosa lining the urinary bladder is additionally lined with transitional epithelial tissue that can stretch to store large volumes of urine. This tissue also protects the bladder from alkaline or acidic urine. 2 Next comes the submucoal lining which is actually a connective tissue layer consisting of nervous tissue and blood vessels which control and support the other surrounding layers. 3 The submucosa is next lined with a layer of visceral muscles which provide the bladder the ability to contract and expand. This visceral muscle layer is called as muscularis and is also called detrusor muscle. The muscularis form the internal urethral sphincter surrounding the urethral opening. It holds the urine in the bladder and relaxes to allow the outflow of urine. 4 Due to the positioning of the urinary bladder in the abdominopelvic cavity, its outermost layer consists of serous membrane which protects the bladder against friction between organs in the cavity. 5 The inferior and lateral sides of the bladder has a layer of a loose connective tissue namely adventitia. This tissue connects the bladder to the tissues surrounding the pelvis.
