unit 25(quiz 10) urinary system

The normal pH for urine ranges between

4.5 and 8.0.

What is the correct sequence of organs for the formation and elimination of urine?

Kidney, ureter, bladder, urethra

Which of the following are primary organs of the urinary system?

Kidneys,Ureters,Urinary bladder,Urethra

Explain the order of kidney structures (and thus urine flow) leaving the renal papilla until reaching the urinary bladder.

Minor calyces,Major calyces,Renal pelvis,Ureter

Which of the following choices lists structures in the order in which urine flows through them?

Minor calyx, major calyx, renal pelvis

Where are the renal pyramids located within the kidney?

Renal medulla

Both the proximal convoluted tubule and the distal convoluted tubule reside in the cortex of the kidney.(true or false)

True

Collecting ducts are larger than collecting tubules.(true or false)

True

The specific gravity of urine is its density compared to that of water, and the more solutes urine has, the higher its specific gravity.(true or false)

True

Typically pH is regulated by both reabsorption of bicarbonate and secretion of H+.(true or false)

True

Upon leaving the renal pelvis, urine passes directly into a ureter.(true or false)

True

Usually the urine of someone with a high-protein diet does not contain any bicarbonate ions, as all of it that is filtered is reclaimed from the tubules.(true or false)

True

Where in the urinary tract is transitional epithelium found?

Ureters,urinary bladder,prostatic urethra

The fibrous capsule of the kidney is composed of___connective tissue.

dense irregular

The ____________ is part of the ____________ layer of the bladder. This tissue contracts to help expel urine from the bladder.

detrusor muscle,muscularis externa

What is the value of transitional epithelium in the urinary system?

distension.

The thick tangle of capillary loops found within a corpuscle is known as the

glomerulus.

Normal urine has a specific gravity that is ________ than the specific gravity of pure water; dehydration leads to a __________ in the specific gravity of urine.

higher,increase

The concave medial border of the kidney is called the __________.

hilum

The muscularis layer of the urinary bladder is formed by three layers of smooth muscle that includes the

internal urethral sphincter.

The ____________ of the bladder is the deepest part of the mucosa. It is a layer of loose fibroelastic tissue that contains many lymphoid elements.

lamina propria

The expulsion of urine from the bladder is referred to as

micturition.

The first structure in the kidney to collect newly formed urine is the

minor calyx.

The kidneys are located ___________to the peritoneum.

posterior

The renal corpuscle is located within the

renal cortex.

The ____________ of the urinary bladder is a layer of connective tissue that contains blood vessels and nerves.

submucosa

The ____________ of the urinary bladder lines the lumen and prevents urine from diffusing from the lumen.

transitional epithelium

The ___________ transfer urine from the kidneys to the urinary bladder.

ureters

The ____________ is a hollow organ that functions to store urine.

urinary bladder
