The Urinary Bladder
The correct answer to the question is option 'B' - the urinary bladder. The urinary bladder is a small muscular balloon-like organ that plays a crucial role in the storage and elimination of urine from the body. It is located in the pelvic cavity, just behind the pubic bone.
Function
The urinary bladder serves as a temporary storage reservoir for urine before it is expelled from the body through the process of urination. It can expand and contract depending on the volume of urine it contains.
Structure
The urinary bladder is made up of smooth muscle tissue known as the detrusor muscle. It is composed of several layers, including an inner mucous membrane, a submucosal layer, a muscular layer, and an outer serous layer.
Urinary Bladder and Urine Storage
When the bladder is empty, it appears small and collapsed. However, as urine is produced by the kidneys and travels through the ureters, it gradually fills up the bladder. The bladder walls stretch and expand to accommodate the increasing volume of urine, similar to a balloon filling up with air. This stretching is made possible by the elasticity of the detrusor muscle.
Urination and Bladder Contraction
When the bladder is full and it is time to empty the urine, a complex process called urination or micturition occurs. Nerve signals from the brain and spinal cord stimulate the detrusor muscle to contract while simultaneously relaxing the urinary sphincter muscles. This coordinated contraction and relaxation allow the bladder to forcefully expel urine through the urethra.
Conclusion
In summary, the small muscular balloon-like organ that swells up when it is full of urine and shrinks in size again after urine has been emptied out of it is the urinary bladder. It plays a vital role in the storage and elimination of urine from the body.
