Kidney Study Flashcards

Each afferent arteriole supplies one functional unit of the kidney called

a nephron

Each afferent arteriole leads to a ball of capillaries

called

glomerulus

Where is the glomerulus enclosed?

in a sphere called the glomerular capsule

The glomerular capsule has

an outer parietal layer (simple

squamous epithelium) and inner visceral layer (podocytes)

Between the parietal and visceral layers is

the filtrate-collecting capsular

space.

The efferent arteriole leaves

the glomerular capsule and gives rise to the peritubular capillaries or the vasa recta

A nephron consists of two principal parts called

the renal corpuscle (glomerulus plus the glomerular capsule) and the renal tubule (proximal

convoluted tubule, nephron loop, distal convoluted tubule, and collecting duct.)

he proximal convoluted tubule is the ..

longest and most

coiled part of the nephron.

What does the proximal convoluted tubule have?

a simple cuboidal epithelium with prominent microvilli, which attests to the great deal of absorption

that occurs here.

The collecting duct receives fluid from..

the distal convoluted tubules of several nephrons as it passes back into the

medulla.

the flow of fluid from the point where the glomerular filtrate is formed to the point where urine leaves the body is:

glomerular

capsuleproximal convoluted tubulenephron loopdistal convoluted tubulecollecting ductpapillary ductminor calyxmajor

calyxrenal pelvisureterurinary bladderurethra.

How many layers of connective tissue protect the kidneys?

3

The most superfical layer of kidney

renal fascia

Middle layer of kidney

perirenal fat capsule

Deepest layer of kidney

fibrous (renal) capsule.

From superficial to deep they are the.. (kidney)

renal fascia, perirenal fat capsule, and

the fibrous (renal) capsule.
