The ureters are responsible for storing urine until it is expelled from the body.

Answer

The ureters transport urine from the kidneys to the bladder, where it is stored and later eliminated.

The ureters propel urine from the kidneys to the bladder through peristaltic contractions.

Answer

The ureters prevent the backflow of urine into the kidneys by means of specialized valves.

Question 43

Approximately what is the normal bladder capacity in an adult human?

Accepted Answer

The average bladder capacity in adults ranges from 300 to 500 milliliters (mL).

Answer

The bladder can typically hold 900 to 1200 mL of urine before triggering the urge to urinate.

A normal bladder capacity is usually around 100 to 200 mL, which is sufficient for temporary urine storage.

Epinephrine, a hormone released in response to stress, can have indirect effects on bladder function but is not the primary stimulator of bladder contraction.

Answer

Progesterone, a female sex hormone, is involved in preparing the uterus for pregnancy and does not have a primary role in bladder function.

Answer

Testosterone, a sex hormone, is primarily involved in male reproductive functions and does not directly influence bladder contraction.

The urethra serves as a passageway for the transportation of urine from the bladder to the exterior of the body during urination.

Answer

The urethra functions as a storage site for urine, holding it until the bladder is full.

Answer

The urethra is involved in the filtration of urine, removing impurities and concentrating the waste products.

Answer

The urethra is responsible for the production of urine by filtering waste products from the blood.

Transitional epithelium, characterized by its ability to stretch and contract, is the type of tissue that lines the lumen of the ureters.

Answer

Cuboidal epithelium, consisting of cube-shaped cells, is found in various glands and ducts but not in the lining of the ureters.

Answer

Squamous epithelium, made up of thin, flattened cells, is typically found in areas subjected to friction, such as the skin, but not in the ureters.

Answer

Columnar epithelium, composed of tall, column-shaped cells, is commonly found in the digestive tract but not in the ureters.

Question 47

The vesical artery, a branch of the internal iliac artery, is the primary blood vessel that supplies the bladder with blood.

Answer

The umbilical artery, which is essential for fetal circulation, is not connected to the bladder in adults.

Answer

Accepted Answer

The trigone is the triangular-shaped area at the base of the bladder where the two ureteric orifices, where the ureters enter the bladder, and the internal urethral orifice, where the urethra exits the bladder, are located.

Answer

The bladder neck is the narrow, muscular region where the bladder connects to the urethra, not the triangular region at the base.
