Acute Renal Failure (ARF) Lecture 4 Quiz

Bladder Capacity

• The adult bladder can typically hold around 400 to 600 milliliters (mL) of urine before the urge to urinate becomes strong.
• This capacity can vary depending on factors like age, gender, and overall health.

Nephrons in the Kidneys

• Each kidney contains approximately one million nephrons, the functional units responsible for filtering waste products from the blood and producing urine.

Kidney Location

• The kidneys are located in the retroperitoneal space, which is the space behind the abdominal cavity, on either side of the vertebral column.
• They are typically positioned at about the level of the 12th thoracic vertebra to the 3rd lumbar vertebra.

Ureter Function

• The ureters are two narrow tubes that transport urine from the kidneys to the bladder.
• They have peristaltic contractions, which are rhythmic muscle movements that help propel urine downward.

Male Urethra

• The prostate gland surrounds the urethra posteriorly and laterally in males.
• This gland contributes to the production of seminal fluid and plays a role in male reproductive health.
