Quick Answer: Which Of These Hormones Causes The Kidney To Increase The Body’s Content Of Sodium?

Which of hormone causes the kidney to increase the body’s content of sodium?

Aldosterone is a steroid hormone that causes an increase in sodium reabsorption and potassium excretion at the distal tubule and collecting duct of the nephron.

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. If the renin-angiotensin-aldosterone system is too active, blood pressure will be too high.

Which of the following structures consist of specialized cells that secrete renin when glomerular blood pressure falls?

Juxtaglomerular cells (JG cells), also known as granular cells are cells in the kidney that synthesize, store, and secrete the enzyme renin. They are specialized smooth muscle cells mainly in the walls of the afferent arterioles (and some in the efferent arterioles) that deliver blood to the glomerulus.

Which section of the nephron filters blood plasma quizlet?

– this is the part of a nephron where blood plasma is filtered. * Glomerular (Bowman’s) Capsule – which is a dead end tube that surrounds the glomerular capillaries in the form of a double walled cup that recieves filtrate from the capillaries. – this is the part of the nephron into which filtered fluid passes.

What hormones regulate sodium and potassium levels?

aldosterone: A mineralocorticoid hormone that is secreted by the adrenal cortex and regulates the balance of sodium and potassium in the body.

What hormones regulate the balance of sodium and potassium levels?

aldosterone: A mineralocorticoid hormone that is secreted by the adrenal cortex and regulates the balance of sodium and potassium in the body.

Which of the following brings oxygenated blood into the kidney?

Blood comes to the kidneys from the abdominal aorta and inferior vena cava, the large arteries and veins that are part of the ascending aorta. Oxygenated blood is brought to the kidneys from a small branch called the renal artery.

What percentage is reabsorbed and returned to the circulation?

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 area is sensitive to the hormone ADH?

ADH is stored in neurons within the hypothalamus. These neurons express osmoreceptors that are exquisitely responsive to blood osmolarity and respond to changes as little as two mOsm/L.

What is JGA?

juxtaglomerular apparatus (JGA) A region of tissue found in each nephron in the kidney that is important is regulating blood pressure and body fluid and electrolytes. The JGA also includes chemoreceptor cells of the adjacent region of the distal tubule, which form a tightly packed array called the macula densa.

What is the function of Juxtaglomerular cells?

The juxtaglomerular apparatus functions to maintain blood pressure and to act as a quality control mechanism to ensure proper glomerular flow rate and efficient sodium reabsorption. The urethra extends from the bladder to the surface of the body. It consists of an epithelium-lined lumen and a smooth muscle layer.

What is the significance of JGA in kidney function?

The juxtaglomerular apparatus is a specialized structure formed by the distal convoluted tubule and the glomerular afferent arteriole. It is located near the vascular pole of the glomerulus and its main function is to regulate blood pressure and the filtration rate of the glomerulus.

What are the two main divisions of the nephron?

A nephron is made of two parts:

  • a renal corpuscle, which is the initial filtering component, and.
  • a renal tubule that processes and carries away the filtered fluid.

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 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.
