PLAY
Kidney (Left)
E
Function: removing waste products from the blood and regulating the water fluid levels
Inferior Vena Cava
A
Function: return oxygen poor blood to heart
Renal Artery
B
Function: supply oxygen rich blood to kidneys
Renal Vein
D
Function: return oxygen poor and filtered blood to the inferior vena cava
Hilus of kidneys
C
Function:transmits the vessels, nerves, and ureter
Ureter
F
Function: move urine from collecting tubule to urinary bladder
Urinary bladder
G
Function: hold urine
Urethra
H
Function: allow urine to exit the body
Cortex (of Kidney)
A
Function: filter blood and to remove the waste products
Medulla (of Kidney)
B
Function: contains the structures of the nephrons responsible for maintaining the salt and water balance of the blood
major renal calyx
C
Function:provides a channel for urine to flow through to the ureter
renal papillae
D
Function: drain urine into the minor calyxes and thence to the ureters
Renal pelvis
E
Function: drain urine into ureters
Minor renal calyx
F
Function: drain urine from renal papillae and pass it on to the major renal calyx
renal pyramids
G
Function: part of the medulla of the kidney that contains the structures of the nephrons responsible for maintaining the salt and water balance of the blood
Capsule of kidney
I
Function: cover and protect kidney
Mucosa (of urinary bladder)
A
Function: maintain water-proofing of internal bladder; expand to hold urine
Rugae (of urinary bladder)
B
Function: allow bladder to expand to hold urine
Trigone (of urinary bladder)
C
Function: signal the brain when the bladder is full
Cortex (of kidneys, histology)
B
Function:filter blood and to remove the waste products
Medulla (of kidneys, histology)
A
Function: maintain salt and water balance of blood
Glomeruli (of kidneys, histology)
A
Function: first site of filtration of blood in kidneys
Glomerulus (of kidneys, histology, 400x)
D
Function: first site of filtration of blood in kidneys
Bowman's Capsule (glomerular capsule, kidneys, histology 400x)
E
Function: contain filtrate from glomerular capillaries)
distal convoluted tubule (of kidneys, histology, 400x)
A
Function: acts as a site for selective secretion and reabsorption as water and ions pass between the blood and the filtrate across the tubule membrane
proximal convoluted tubule (of kidneys, histology, 400x)
B
Function: regulates the pH of the filtrate by exchanging hydrogen ions in the interstitium for bicarbonate ions in the filtrate; responsible for secreting organic acids, such as creatinine and other bases, into the filtrate
Simple squamous epithelium (of kidneys, histology, 400x)
C
Function: external layer of glomerular capsule
Simple cuboidal epithelium (of kidneys, histology, 400x)
F
Function: form the tubules of the nephron
Transitional Epithelium (urinary bladder, histology, 100x)
A
Function: allow for expansion of the lumen of the bladder
Smooth Muscle (urinary bladder, histology, 100x)
B
Function: control micturition
Renal corpuscle
D
Function: contains glomerulus and bowman's capsule; first site of blood filtration
Glomerular capsule (Bowman's capsule)
H
Function: contain filtrate from glomerular capillaries
Parietal Layer of Glomerular Capsule
E
Function: outer layer of Glomerular capsule
Visceral Layer of Glomerular Capsule
G
Function: cover glomerular capillaries and allow filtrate into Glomerular capsule
glomerular capillaries
F
Function: bring blood into glomerulus to allow filtrate into Glomerular capsule
afferent arteriole
B
Function: bring blood into the glomereulus
efferent arteriole
C
Function: Carry blood out of glomerulus
juxtaglomerular apparatus
A
Function: regulates the function of each nephron
proximal convoluted tubule
C
Function: regulates the pH of the filtrate by exchanging hydrogen ions in the interstitium for bicarbonate ions in the filtrate; responsible for secreting organic acids, such as creatinine and other bases, into the filtrate
loop of Henle
H
Function:to create a concentration gradient in the medulla of the kidney
distal convoluted tubule
D
Function: acts as a site for selective secretion and reabsorption as water and ions pass between the blood and the filtrate across the tubule membrane
Collecting tubule
A
Function: to collect urine from distal convoluted tubule of nephron
peritubular capillaries
F
Function: supply the blood for reabsorption and secretion in medulla of kidneys
Vasa Recta
G
Location: surround the loop of Henle in a nephron
Function: maintenance of countercurrent exchange that prevent washout of the concentration gradients established in the renal medulla
Cortical radiate vein
A
Function: take deoxygenated blood from peritubular capillaries/vasa recta
Cortical radiate artery
B
Function: take blood to afferent arteriole that enters glomerulus
Arcuate vein
C
Function: take deoxygenated blood from cortical radiate vein and convey it to interlobar vein
Arcuate Artery
D
Function: take oxygenated blood from interlobar artery to the cortical radiate artery
Interlobar vein
E
Function: move deoxygenated blood from arcuate vein to renal vein
