Which of the following Does not describe the juxtaglomerular com Its granular cells produce rennin It helps control systemic blood pressure Its macula densa cells produce aldosterone It regulates the rate of filtrate formation

After the glomerulus, blood travels through the:   Question 45 options:   Efferent arteriole   Afferent arteriole   Peritubular capillaries   Connecting ducts

What is the difference between the glomerular capillaries and the peritubular capillaries? How do these relate to afferent and efferent arterioles?  Why do the efferent arterioles have oxygenated blood? (The answer isn’t “they are called arterioles, therefore they have oxygenated blood.)

Which of the following is TRUE about how water is handled by che nephron? Vasopressin inserts pumps in the collecting duct membrane that move water against its concentration gradient. Water is actively reabsorbed from the proximal tubule, and Na+ follows down its diffusion gradient. Water is actively secreted into the descending loop of Henle. Water reaborption depends on activity of active transport mechanisms related to Na+ The permeability of the ascending limb of the loop of Henle is modified by vasopressin

Can you help me fill in the following blanks with the correct terms with the word bank below?

Changes in blood pressure ( MAP ) have the potential to alter glomerular filtration rate ( GFR ) by directly changing which of the following factors below ? glomerular capillary hydrostatic pressure Bowman's capsule hydrostatic pressure glomerular osmotic pressure Bowman's capsule osmotic pressure

The forces that oppose glomerular filtration are:   W. osmotic force of proteins in the glomerular capillariesX. blood pressure in the glomerular capillariesY. fluid pressure in Bowman’s capsuleZ. ATP-dependent processes in the nephron Select one: a. if only W, X and Y are correct b. if only W and Y are correct c. if only X and Z are correct d. if only Z is correct e.   if all are correct

Renal Physiology (human)     The foot processes of podocytes surround the peritubular capillaries of both cortical and juxtamedullary nephrons.   Vasa recta are long, straight blood vessels associated with juxtamedullary nephrons.   Canagliflozin is a therapeutic drug that acts on the collecting duct to decrease glucose reabsorption.

A patient arrives in the ER after suffering a fall from a third floor window. He has multiple obvious fractures, is unconscious and unresponsive, and has a blood pressure of 50/0 and pulse that is very rapid and thready.  One of the many “first things” to be done for him is insertion of a foley catheter into his urinary bladder to determine if his glomerular filtration pressure is greater than 10mmHg.  Why? A) If his blood pressure is adequate to give him a glomerular filtration pressure greater than 10mmHg, he will make at least 50cc/hr of urine and thus will be able to regulate his electrolytes pH, and measuring urine output, thus glomerular filtration pressure, tells the medical staff whether their resuscitation efforts are working and adequate B) None of these answers is correct C) Measuring urine output, thus glomerular filtration pressure, tells the medical staff whether their resuscitation efforts are working and adequate D) Inserting a foley catheter is actually not an…

Is this statement true or false:  The juxtagomerular apparatus also pays a role in controlling the net glomerular filtration rate. If the GFR is high macula densa cells detect increase blood pressure. These cells respond by decreasing releasing of water which results in vasoconstriction of afferent. This decreases the GFR.
