FAQ: Which Of These Hormones Causes The Kidney To Increase The Body’S Content Of Sodium?

What is a mechanism the kidney uses to raise systemic blood pressure?

Aldosterone causes the tubules of the kidneys to increase the reabsorption of sodium and water into the blood. This increases the volume of fluid in the body, which also increases blood pressure.

Which section of the nephron performs most of the glucose and water reabsorption?

The proximal convoluted tubule is where a majority of reabsorption occurs. About 67 percent of the water, Na+, and K+ entering the nephron is reabsorbed in the proximal convoluted tubule and returned to the circulation.

Which section of the nephron filters blood plasma quizlet?

Nephrons are the functional units of the kidney! It consists of two parts: the renal corpuscle and the renal tubule. The renal corpuscle is where blood plasma is filtered.

Which of the following portions of the nephron filters blood plasma?

Filtration of the blood plasma takes place in the renal corpuscle. This is the proximal end of the nephron, which is expanded into an ovoid structure. The renal corpuscles are always found in the renal cortex.

How do hormones vessels and the kidneys affect blood pressure?

As blood passes through your kidneys, special cells “measure” blood pressure in the blood vessels leading to your kidneys (renal arteries) and adjust the amount of the hormone renin that they secrete. Renin controls the production of two other hormones, angiotensin and aldosterone.

Does the kidney produce hormones that assist in digestion?

The gastrointestinal tract produces various hormones that aid in digestion. The kidneys produce renin, calcitriol, and erythropoietin. Adipose tissue produces leptin, which promotes satiety signals in the brain.

What is reabsorbed in the nephron?

In renal physiology, reabsorption or tubular reabsorption is the process by which the nephron removes water and solutes from the tubular fluid (pre-urine) and returns them to the circulating blood. Thus, the glomerular filtrate becomes more concentrated, which is one of the steps in forming urine.

What substances are reabsorbed in the nephron?

Most of the Ca++, Na+, glucose, and amino acids must be reabsorbed by the nephron to maintain homeostatic plasma concentrations. Other substances, such as urea, K+, ammonia (NH3), creatinine, and some drugs are secreted into the filtrate as waste products.

What are the two main subdivisions of the nephron?

Key Points

  • Kidneys contain two types of nephrons, each located in different parts of the renal cortex: cortical nephrons and juxtamedullary nephrons.
  • A nephron comprises a renal corpuscle, a renal tubule, and the associated capillary network.

Where does the ureter penetrate the kidney quizlet?

Where does the ureter penetrate the kidney? The ureter, blood vessels, and nerves penetrate the kidney on its medial surface. The fibrous capsule is a layer of adipose tissue that surrounds the kidney.

What causes filtration in a nephron quizlet?

The main force that causes filtration in a nephron is glomerular hydrostatic pressure.

What are the 4 parts of the renal tubules?

It contains four segments: the pars recta (the straight descending limb of proximal tubule), the thin descending limb, the thin ascending limb, and the thick ascending limb.

Where is the nephron found?

The nephrons found in the kidneys (mesonephros) of amphibians and most fish, and in the late embryonic development of more advanced vertebrates, are only slightly more advanced in structure. The most advanced nephrons occur in the adult kidneys, or metanephros, of land vertebrates, such as reptiles, birds, and mammals.

What is a nephron and name five main components of a nephron?

The major parts of the nephron are the renal corpuscle, the proximal convoluted tubule, the loop of Henle, and the distal convoluted tubule. Each part has a significant, distinct function in urine production. The loop of Henle is a critical region where the filtrate is further adjusted for water and solute balance.
