All of the following are wastes removed by the kidneys EXCEPT:

Water

All of the following are functions of the kidneys EXCEPT:

Removal of worn out RBC's and pathogens from the blood

Urine produced by thee kidneys is transported by the __________ to the urinary bladder where it is stored until being excreted from the body.

Ureters

Choose the organ of the urinary system and corresponding function that are matched INCORRECTLY.

The urinary bladder excretes waste in urine

Which is NOT a major function of the kidney?

Regulation of blood cell size

This is the formation of a new glucose molecule.

Gluconeogenesis

Which of the following is a waste product normally excreted by the kidneys?

Urea

The kidneys lie within the peritoneal membrane.

False

A nephron includes a:

1. Renal corpuscle

2. Renal tubule

3. Renal capsule

1 & 2 are correct

Which is NOT a function of the kidneys?

All of these choices are functions of the kidneys

Which of the following correctly lists the connective tissues surrounding the kidneys starting with the most superficial layer?

Renal fascia, adipose capsule, renal capsule

The renal __________ is part of the renal parenchyma.

cortex

Which of the following correctly traces the flow of blood through the kidney after entry through the renal arteries and prior to entry into the peritubular capillaries?

Segmental arteries, interlobar arteries, arcuate arteries, interlobular arteries, afferent arteriole, glomerulus, efferent arteriole

Juxtamedullary nephrons

Allows excretion of very dilute or concentrated urine

The kidneys lie within the ___________ membrane.

None of these

These blood vessels extend through the renal cortex and arise from arcuate arteries.

Cortical radiate artery

The middle layer of tissue surrounding the kidneys and protecting them from trauma.

Perirenal fat capsule

The kidneys produce two hormones, calcitriol and ___________.

erythropoietin

Why are the kidneys said to be retroperitoneal?

They are posterior to the peritoneum

Identify the three layers that surround the kidney from internal to external:

Renal capsule, adipose capsule, renal fascia

Renal pyramids occur in the __________ of the kidney.

Renal medulla

A drop of blood entering a renal artery would pass through a segmental artery, interloper artery and ___________ before reaching a cortisol radiate artery.

Arcuate artery

The two main parts of the nephron are the renal corpuscle and the renal tubule.

True

This is a smooth, transparent dense irregular connective tissue that is continuous with the out coat of the ureter.

Fibrous capsule

The portion of the kidney that extends between the renal pyramids is called the:

Renal columns

What is the correct order of blood flow through the kidneys?

Interlobar arteries > arcuate arteries > glomerular capillaries > arcuate veins

C

This is composed of dense irregular tissue that runs continuous with the ureter.

B

This layer's main function is to protect the kidney from trauma and hold it's place within the abdominal cavity.

A

This layer runs deep to the peritoneum on the anterior surface of the kidneys.

A

This can be divided into the cortical zone and the juxtamedullary zone.

F

This structure is the apex of the renal pyramid.

C

Which of the following labels correctly identifies the juxtaglomerular apparatus?

Filtered fluid leaving the glomerular capillaries immediately enters the:

Glomerular capsule

Which correctly associates structure with tissue type?

Descending limb and thin ascending limb of nephron loop > simple squamous epithelial cells

The renal corpuscle consists of the glomerulus and the glomerular capsule.

True

The juxtaglomerular apparatus consists partially of the:

Juxtaglomerular cells of an afferent arteriole

_____________ selectively removes material from the tubular fluid and returns to the blood while ___________ removes materials from the blood.

Tubular reabsorption; tubular secretion

Which is the correct order of filtrate flow?

Glomerular capsule, proximal convoluted tubule (PCT), loop of Henle, distal convoluted tubule (DCT), collecting duct
