What would happen if capsular hydrostatic pressure was increased?

What would happen if the capsular hydrostatic pressure were increased above normal? A) Net filtration would increase above normal. Net filtration would decrease. C) Filtration would increase in proportion to the increase in capsular pressure.

All this is further explained here. Consequently, what would happen if the capsular hydrostatic pressure CHP were increased above normal?

Net filtration would decrease.

Furthermore, why glomerular hydrostatic pressure is high? The hydrostatic pressure in the glomerular capillaries is essentially the blood pressure in the glomerulus. This, then, causes the glomerular filtration rate to decrease as higher hydrostatic pressure in the Bowman’s space counteracts the hydrostatic pressure in the glomerulus that favors the filtration of blood.

Keeping this in view, what is capsular hydrostatic pressure?

Capsular hydrostatic pressure (CHP) is the pressure exerted against the filtration membrane by the filtrate in Bowman’s capsule during filtration.

Which part of the brain controls the micturition reflex?

The micturition reflex is a bladder-to-bladder contraction reflex for which the reflex center is located in the rostral pontine tegmentum (pontine micturition center: PMC). There are two afferent pathways from the bladder to the brain.

Which structure is incorrectly matched with a function?

Which structure is INCORRECTLY matched with a function? -Cortical nephrons form the majority of nephrons in the kidney. -The efferent arteriole of the cortical nephrons supplies the peritubular capillaries.

Why is the fatty tissue surrounding the kidneys important?

Kidneys. Each kidney is held in place by connective tissue, called renal fascia, and is surrounded by a thick layer of adipose tissue, called perirenal fat, which helps to protect it. A tough, fibrous, connective tissue renal capsule closely envelopes each kidney and provides support for the soft tissue that is inside.

Where in the nephron does most solute reabsorption occur?

Reabsorption. Reabsorption takes place mainly in the proximal convoluted tubule of the nephron . Nearly all of the water, glucose, potassium, and amino acids lost during glomerular filtration reenter the blood from the renal tubules.

What is the largest component of urine by weight other than water?

Urea

What is the function of the nephron loop?

Loop of Henle. Loop of Henle, long, U-shaped portion of the tubule that conducts urine within each nephron (q.v.) of the kidney of reptiles, birds, and mammals. The principal function of the loop of Henle appears to be the recovery of water and sodium chloride from the urine.

Which hormones are the most important hormone regulators of electrolyte reabsorption and secretion?

Aldosterone, often called the “salt-retaining hormone,” is released from the adrenal cortex in response to angiotensin II or directly in response to increased plasma K+. It promotes Na+ reabsorption by the nephron, promoting the retention of water. It is also important in regulating K+, promoting its excretion.

What is the mechanism of water reabsorption by the renal tubules?

The Role of Aquaporins in the Kidneys

The majority of water reabsorption that occurs in the nephron is facilitated by the AQPs. Most of the fluid that is filtered at the glomerulus is then reabsorbed in the proximal tubule and the descending limb of the loop of Henle.

What is the cause of capsular hydrostatic pressure?

Capsular hydrostatic pressure is the pressure exerted by fluid in the glomerular capsule against the fluids coming out of the glomerulus. All of the following would stimulate the release of renin from granular cells, EXCEPT inhibition by the macula densa cells.

How is NFP calculated in anatomy?

Or: NFP = 55 – [15 + 30] = 10 mm Hg (Figure 25.4. 1). Figure 25.4. 1 – Net Filtration Pressure: The NFP is the sum of osmotic and hydrostatic pressures.

What are the three main waste products in urine?

Urine is about 95% water and 5% waste products. Nitrogenous wastes excreted in urine include urea, creatinine, ammonia, and uric acid. Ions such as sodium, potassium, hydrogen, and calcium are also excreted.

What increases NFP?

Increased permeability and NFP are directly proportional. As permeability increases, NFP increases; as permeability decreases, NFP decreases. NFP and GFR are directly proportional. As NFP increases, GFR increases; as NFP decreases, GFR decreases.

What is blood osmotic pressure?

Osmotic pressure is a measure of the concentration of solutions. It does not cause actual, physical pressure. High osmotic pressure in the blood will cause water to be taken out of the cells. The kidneys usually maintain osmotic pressure under very tight control, so elevated osmotic pressure usually is abnormal.
