Question

Which of the following is a transporting tube leading from the bladder which brings urine outside the body via penis?
A. Ureter
B. Epididymis
C. Ejaculatory duct
D. Urethral meatus

Answer 1

Hint: The liquid waste that is expelled from our bodies through metabolism is called urine. It is created by the kidney's filtration and reabsorption process. The bladder holds the prepared pee, which is afterwards expelled outside through tubes.

Complete Step by Step Answer:
An organ with the shape of a bean, the human kidney grows in pairs. By way of metabolism, it creates urine, which is a nitrogenous waste that is rich in urea as well as other excretory products including water, salts, glucose, and electrolytes, among others, and is released into the environment.
The nephrons filter blood, resulting in the formation of urine. Filtration, reabsorption, secretion, and excretion from the blood are carried out by the glomerulus, convoluted tubules, and collecting ducts, which also create urine. The tubes known as the ureter are used to pass the prepared urine and collect it in the bladder-like urinary cavity. The accompanying urinary system diagram shows that there are two of these tubes, one coming out of each kidney.
A tube known as the urethra emerges from the urinary bladder and transports urine to the outside. The urethra is a short, muscular tube that is different in length in men and women. The urethra in a guy travels through the penis. The length is tiny and can be found between the clitoris and the vagina in females.
Hence, the correct option is D. Urethral meatus.

Note: Urination is the process of passing urine. The brain sends a signal to the bladder's muscles to contract. As a result, the body's urine is forced out through the urethra. The vas deferens and the urethra are linked in males. It acts as a conduit for sperm ejaculation.
