Urinary System Basic Facts Quiz: Trivia!

2.

Slender tubes that carry urine from the kidneys to the urinary bladder for temporary storage.

Urethra
Ureters
Tubular reabsorption
Renal tubule

Correct Answer

A. Ureters

Explanation

The correct answer is Ureters. The ureters are slender tubes that carry urine from the kidneys to the urinary bladder for temporary storage. They play a vital role in the urinary system by transporting urine from the kidneys, where it is produced, to the bladder, where it is stored before being eliminated from the body.

3.

Bean shaped organs located on each side of the vertebral column and against the upper, posterior wall of the abdominal cavity.

Ureters
Spleen
Gallbladder
Kidneys

Correct Answer

A. Kidneys

Explanation

The correct answer is kidneys. The kidneys are bean-shaped organs located on each side of the vertebral column and against the upper, posterior wall of the abdominal cavity. They are responsible for filtering waste products from the blood and producing urine.

4.

Blood vessels, lymphatic vessels, nerves, and the ureter enter or exit through this.

Renal corpuscles
Hilum
Glomerular
Nephrons

Correct Answer

A. Hilum

Explanation

The correct answer is Hilum. The hilum is a depression on the surface of an organ where blood vessels, lymphatic vessels, nerves, and the ureter enter or exit. In the context of the given options, renal corpuscles, glomerular, and nephrons are all related to the structure and function of the kidney, but they do not specifically refer to the site where these vessels and structures enter or exit the kidney. Therefore, the correct answer is hilum.

5.

The three regions of the kidney are the cortex, medulla, and pelvis.

True
False

Correct Answer

A. True

Explanation

The explanation for the given correct answer is that the kidney is indeed divided into three main regions: the cortex, medulla, and pelvis. The cortex is the outermost layer of the kidney, where the majority of the filtration process takes place. The medulla is the middle layer, consisting of renal pyramids that help transport urine to the pelvis. The pelvis is the innermost region, collecting urine from the medulla and directing it towards the ureter. Therefore, the statement "The three regions of the kidney are the cortex, medulla, and pelvis" is true.

6.

Thin, outermost layer of the kidney.

Renal medulla
Renal cortex
Renal corpuscles
Both A and C

Correct Answer

A. Renal cortex

Explanation

The renal cortex is the correct answer because it is the thin, outermost layer of the kidney. It contains the renal corpuscles, which are responsible for filtering the blood and producing urine. The renal medulla, on the other hand, is the inner region of the kidney that contains the renal pyramids and renal tubules. Therefore, the renal cortex is the most appropriate option as it accurately describes the location and structure of the outer layer of the kidney.

7.

Interior to the cortex

Renal corpuscles
Renal medulla
Renal Cortex
All the above

Correct Answer

A. Renal medulla

Explanation

The renal medulla is the correct answer because it is located interior to the renal cortex. The renal medulla is the innermost part of the kidney and is responsible for filtering and concentrating urine. It contains structures called renal pyramids, which are made up of tubules and blood vessels. The renal cortex, on the other hand, is the outer part of the kidney and contains the renal corpuscles, which are responsible for filtering blood and producing urine. Therefore, the renal medulla is the correct choice as it is the part of the kidney that is located interior to the cortex.

8.

Microscopic tubules

Nephrons
Renal Artery
Proximal convoluted tubule
Both B and C

Correct Answer

A. Nephrons

Explanation

Nephrons are the functional units of the kidneys responsible for filtering waste products and excess water from the blood. They consist of microscopic tubules, including the proximal convoluted tubule, which is involved in reabsorbing important substances back into the bloodstream. The renal artery supplies blood to the nephrons, allowing them to perform their filtration and excretion functions. Therefore, the correct answer is "Nephrons" because they are the structures that contain the microscopic tubules and are supplied by the renal artery.
