This Exam contains:
-Guarantee passing score -60 Questions and Answers -format set of multiple-choice -Expert-Verified Explanation Question 1: Voiding has both voluntary and involuntary components. The voluntary sphincter is the ________
Answer:
External uretral sphincter
Question 2: site of filtration formation
Answer:
glomerulus Question 3: What structural modifications of certain tubule cells enhances their ability to reabsorb substances from the filtrate?
Answer:
Microvilli..increases surface area
Question 4: Explain why the glomerulus is such a high pressure capillary bed
Answer:
arterioles are high-resistance vessels and the afferent arteriole has a larger diameter than the efferent, the blood pressure in the glomerulus is high for a capillary bed and easily forces fluid and solutes out of the blood into the golmerular capsule
Question 5: it's inner (visceral)membrane forms part of he filtration membrane
Answer:
glomerular capsule
Question 6: Name a condition/s associated with glucose in urine
Answer:
diabetes insipidus & mellitus, and eating a 5lb box of candy
Question 7: Presence of glucose in the urine is indicative of
Answer:
glucosoria
Question 8: Presence of erythrocytes in the urine is indicative of;
Answer:
hematuria Question 9: Explain the relationship between color; specific gravity; and volume of urine
Answer:
Generally, the smaller the volume, the greater the specific gravity (more solutes) and the deeper the color.
Question 10: Name a condition/s associated with albumin in the urine
Answer:
glomerulonephritis and pregnancy, exertion
Question 11: How does a urinary tract infection influence urine pH?
Answer:
High protein diet, increased acidity; vegetarian diet, increases alkalinity
Question 12: Area of cortical tissue running between the medullary pyramids
Answer:
renal column
Question 13: What is the function of the fat cushion that surrounds the kidneys in life?
Answer:
They hold the kidneys in place
Question 14: What are renal calculi, and what conditions favor their formation?
Answer:
Typically clled kidney stones, when urine gecomes excessively concentrated, some of it's solutes begin to crystallize.Question 15: The kidney is a major homeostatic organ because it maintains the (1,2,3)balance of the blood
Answer:
electrolyte, acid base and fluid Question 16: Explain the mechanism of tubular secretion & it's importance iin urine formation process
Answer:
It is the reverse of tubular absobtion and is important for the disposal of substances not in filtrate & is a device for controlling blood ph
Question 17: primary site of tubular reabsorption
Answer:
promximal convoluted tube
Question 18: Smooth membran, tightly adharent to the kidney surface
Answer:
fibrous capsule
Question 19: Define ptosis
Answer:
When the fatty material surrounding the kidneys is reduced the kidneys are less securely anchored and may drop to a more inferior position
Question 20: Name a condition/s associated w/ketone bodies in the urine
Answer:
cystitis, starvation, diabetes mellitus Question 21: Urine is continually formed by the ______ and is routed down the _____ by the mechanism of ______to a storage organ called the ______.
Answer:
kidney's, ureters, circulatory drainage, bladder Question 22: How does the high pressure condition in the glomerulus aid its function of filtrate formation?
Answer:
It forces fluid out & blood comp sm than proteins fr the glomerulus Question 23: What substance is responsible for the normal yellow color of urine?
Answer:
urochrome Question 24: structure that conveys the processed filtrate (urine) to the renal pelvis
Answer:
collecting duct
Question 25: Eventually the urine is conducted to the body _____ by the urethra
Answer:
exterior
Question 26: Portion of the kidney containing mostly collecting ducts
Answer:
minor calyx
Question 27: Name three major nitrogenous wastes found in the urine.
Answer:
Urea, Uric Acid, Creatine
