Answer:

Perirenal fat capsules anchor the kidneys to the dorsal body will in a retroperitoneal position & cushion it against blow.Question 2: Explain the mechanism of tubular secretion, and explain its importance in the urine formation process.

Answer:

1) Blood plasma contains red-white blood cells, blood proteins, glucose, water, nitrogenious waste, and salts.2) Glomerular filtrate contains everything blood plasma does without most of the blood proteins.

Question 3: In the male the urethra is how long?

Answer:

20 centimeters long and transports both urine and sperm.

Question 4: cortex

Answer:

portion of the kidney containing the bulk of the nephron structures (Gross internal anatomy of the pig or sheep) Question 5: Urine is continuously formed by the structural and functional units of the kidneys, the...?

Answer:

nephron

Question 6: The bladder's voluntary sphincter is the....?

Answer:

external sphincter.

Question 7: Ptosis

Answer:

Kidneys are less securely anchored and drop to a more inferior position

Question 8: medulla

Answer:

portion of the kidney containing mostly collecting ducts (Gross internal anatomy of the pig or sheep) Question 9: The kikdney is referred to as an excretory organ because it excretes..?

Answer:

nitrogenous wastes.

Question 10: Micturation

Answer:

Voiding or emptying the bladder. Has both voluntar and involuntary components.

Question 11: Explain why the glomerulus is such a high-pressure capillary bed.

Answer:

1) The bed is fed and drained by arterioles (high resistant vessels) 2) The afferent arteriole (feeder) is larger in diameter than the efferent arteriole (draining)

Question 12: How does the high-pressure condition aid the glomerulus's function of filtrate formation?

Answer:

The higher the capillary pressure, the more filtrate will be formed.Question 13: What is important functionally about the specialized epithelium (transitional epithelium) in the bladder?

Answer:

They have ability to slide over one another, thus decreasing the thickness of the mucosal layer as the bladder fills stretches to accommodate the increased urine volume.Question 14: The kidney is a major homeostatic organ because it maintains the ....?

Question 16: minor calyx

Answer:

a cup-shaped extension of the pelvis that encircles the apex of a pyramid (Gross internal anatomy of the pig or sheep) Question 17: What structural modification of certain tubule cells enhances their ability to reabsorb substances from the filtrate?

Answer:

Their posession of dense microvilli, especially the PCT cells

Question 18: renal column

Answer:

area of cortical tissue running between the medullary pyramids (Gross internal anatomy of the pig or sheep)

Question 19: Define juxtaglomerular complex (apparatus)

Answer:

Region of nephron that plays an important role in forming concentrated urine. Consists of juxtaglomerular and macula densa cells of the DCT.

Question 20: renal pelvis

Answer:

basinlike area of the kidney, continuous with the ureter. (Gross internal anatomy of the pig or sheep)

Question 21: fibrous capsule

Answer:

smooth membrane, tightly adherent to the kidney surface. (Gross internl anatomy of the pig or sheep)

Question 22: incontinence

Answer:

the inability to control the external sphincter of the bladder.Question 23: From the nephron is routed down the ureter by the mechanism of ....?

Answer:

paristalsis
