3. The purpose of this research was not to test the functionality of the transplanted kidneys, but whether or not the human body would reject them. Why are the researchers excited that the kidneys produced ‘robust’ urine and were able to withstand the higher human blood pressure exerted on kidneys in a human body
The macula densa is/are: present in the renal medulla dense tissue present in the outer layer of the kidney cells present in the DCT and collecting tubules present in blood capillaries.
The color of urine is determined mainly by ________. diet filtration rate byproducts of red blood cell breakdown filtration efficiency
Fatty tissue holds the kidneys in place. Extremely rapid weight loss may cause this tissue to shrink so that the kidneys slip from their normal position. On rare occasions, the slippage can put a kink in one or both ureters and block urine flow. Suggest what might then happen to the kidneys.
Which of the following is an example of autoregulation of kidney function? a. The RAAS regulates Na1 by secreting renin when blood pressure or blood volume decreases. b. The ADH system regulates water balance by decreasing water reabsorption and increasing excretion of salt. c. Receptors in the juxtaglomerular apparatus detect a higher salt concentration in the distal convoluted tubule and trigger constriction of the afferent arteriole to reduce glomerular filtration rate. d. ANF is released by the kidney to increase renin release. e. Angiotensin II lowers blood pressure by constricting arterioles.
30, With respect to renal autoregulation, myogenic mechanism refers to Multiple Choice both glomerulus increase of blood flow and macula densa secreting renin are correct ability of macula densa to sense a increase in Na+ content in tubular fluid and secrete renin in response ability of a muscle to contract reflexively without nervous stimulation to adjust blood vessel diameter ability of glomerulus to increase blood flow and increase filtration rate
Minimal change glomerulopathy results in proteinuria and is a major cause of nephrotic syndrome. Briefly explain (make sense of) this statement and outline the changes occurring in the filtration barrier which permit proteins to enter the renal tubules, and explain two consequences of losing plasma proteins from the body.
1. What is gluconeogenesis?2. Explain the biochemical effects underlying the metabolic functions of the renal system in gluconeogenesis as well as insulin metabolism3. What is the relevance of the above in the management of a patient with Chronic kidney disease and diabetes mellitus4. How does renal tubular disease or renal parenchyma disease affect the excretory and haemodynamic regulatory functions of the kidneys
The presence of either protein or glucose in a urinalysis is abnormal, but these two molecules end up in the urine for different reasons. For each of these molecules, briefly describe where in the urine production process (i.e., glomerular filtration, tubular reabsorption or tubular secretion) the problem occurs, and why it might happen.
Please explain this in the most simple way. Explain the kidney's role in water conservation. How much water is reabsorbed (by following other reabsorbed substances) by osmosis? How much water does the nephron loop and collecting duct have to be "tricked" into reabsorbing? How exactly does that work? How do hormones control this process? What effect does alcohol have?
Base your answer off of the information provided: Draw a schematic diagram showing how the osmolarity of the “lumen” solution changes as it moves through Bowman’s capsule, then the proximal tubule, the descending loop of Henle, the bottom portion of the loop of Henle, the ascending portion of Henle, the distal tubule and the collecting duct. Do this both in the presence and absence of antidiuretic hormone (two separate diagrams). Be sure to put numbers indicating osmotic values at appropriate portions of the lumen. Also show the osmotic gradient that exists in the extracellular matrix of the kidney, going from the top of the cortex to the bottom of the medulla; be sure to put in numbers. In a third diagram, draw an “aberrant” kidney in which at the top of the medulla, the extracellular osmotic gradient was 1400 mosm and at the very end of the loop of Henle the osmolarity was 300. Draw the direction of the flow of water and salts as they move through the loop of Henle in this…
2. A patient suffering from a tumor in the hypothalamus produces excessive amounts of ADH, a condition called syndrome of inappropriate ADH (SIADH) production. For this patient, the excessive ADH production is chronic and has persisted for many months. A student nurse keeps a fluid intake-output record on the patient. She is surprised to find that fluid intake and urinary output are normal. What effect was she expecting? Can you explain why urinary output is normal? 3. As part of a physiology experiment, Hardy Breath, an anatomy and physiology student, is asked to breathe through a 3-foot long glass tube. What effect does this action have on his blood pH, urine pH, and respiratory rate?
