A&P2 Lecture Unit 5 Quiz

The portion of the nephron that empties into the collecting duct is the

Distal Convoluted Tubule

Urine is transported by the ________, stored within the ________, and eliminated through the ________. (Module 24.16A)

ureters; urinary bladder; urethra

From deep to superficial, put the following layers of the kidney in order: 1) renal capsule 2) perinephric fat 3) cortex 4) renal fascia

3,1,2,4

A glomerulus is

A knot of capillaries within the Renal corpuscle

Each of the following organs is part of the urinary system except the

Adrenal glands.

Substances larger than ________ do not pass through the filtration membrane.

Albumin

Renal columns are

Bundles of tissue that extend between pyramids from the cortex

The afferent arteriole in the kidney

Carries blood to the glomerulus

Eighty-five percent of nephrons in the human kidney are located in the ________ and have short nephron loops.

Cortex

The condition called ________ is characterized by painful or difficult urination. This condition can be due to pathologic or benign causes.

Dysuria

What effect would increased amounts of aldosterone have on the K+ concentration in urine? (Module 24.10B)

It would increase the K+ concentration in urine because Na+ is retained.

Identify the three distinct processes of urine formation in the kidney. (Module 24.7A)

Filtration, Reabsorption, and Secretion

The process of filtration is driven by

Glomerular hydrostatic pressure

The process of filtration occurs at the

Glomerulus

What effect does an increase in ADH levels have on the DCT? (Module 24.12C)

Increased ADH will increase the number of aquaporins in the DCT which increases water reabsorption and reduces urine volume.

In French, it's "faire de pipi," in Spanish, it's "hacer pipí," in English, it's "I have to pee." What's the medical term for this universal urge to pass urine?

Micturition

Which segment of the nephron is solely involved in the reabsorption of water and sodium and chloride ions? (Module 24.7C)

Nephron Loop

The ________ delivers urine to a minor calyx.

Papillary duct

Where does most nutrient reabsorption occur?

Proximal Convoluted Tubule

The glomerular capsule and the glomerulus make up the

Renal Corpuscle

The cavity of the kidney that receives urine from the calyces is called the

Renal Pelvis

Describe filtrate. (Module 24.4A)

Similar to blood plasma without proteins

The inability to urinate is termed

Urinary Retention

In response to increased levels of aldosterone, the kidneys produce

Urine with a lower concentration of sodium ions.

Regarding kidney function, in reabsorption,

Water and solutes are transported from the tubular fluid, across the tubular epithelium, and into the peritubular fluid.
