Summary Introduction
Introduction:
Nephrons are the “functional unit” of the kidney. The nephron is a Greek word which means for a kidney. Nephrons filter the blood and regulate water and soluble substances. It reabsorbs the water and excretes the rest in the form of urine.

Number the following structures in order of function (1 to 13) during urine formation.
________afferent arteriole
________ascending limb of loop
________collecting duct
________descending limb of loop
________distal convoluted tubule
________efferent arteriole
________glomerular (Bowman’s) capsule & glomerulus (glomerular capillaries)
________nephron loop
________papillary duct
________proximal convoluted tubule
________renal corpuscle
________thick segment of loop
________thin segment of loop
Bladder infections occur when bacteria from outside of the body enter through the urethra and colonize the bladder. Based on the anatomical differences between the sexes, explain why women are more susceptible to bladder infections than men.
Make a sketch of ONE complete Nephron in the kidney and label to show the blood flow (mark with red) and urine flow in this nephron (you can also use arrow to indicate flow direction).
Remember only ONE nephron in your kidney. show the correct location of this nephron (Cortical vs. Juxtamedullary Nephrons) in the entire kidney.
show the correct blood tubings within the nephron (I should be able to tell afferent and efferent arteriole from your sketch; also your nephron is closely associated with two capillary bed )
If sympathetic nervous system stimulation to the kidney decreases __________________ dilate, glomerular filtration rate ____________________ , ____________________ increase, resulting in ____________________ in blood volume and blood pressure
A) Glomeruli; goes up; potassium ion and water output; decrease
B) Afferent arterioles; goes up; sodium ion and water output; decrease
C) Efferent arterioles; goes down, sodium ion and water output; increase
D) Collecting ducts; goes down; ammonium ion and sodium ion outputs; increase
E) None of these answers is correct
