Quick Answer: What Controls The Distal Convoluted Tubule?

What is the process of the distal tubule?

The distal convoluted tubule passes near to the original corpuscle (at the juxtaglomerular apparatus), then leads to a collecting duct.

A collecting duct receives fluid from several distal tubules, then passes through the medulla and drains into the pelvis..

Which structure does the distal convoluted lead to?

The distal convoluted tubule then leads to the collecting duct. What is the correct term for the foot processes on podocytes? The inner layer of Bowman’s capsule is the visceral layer. It consists of cells called podocytes.

What is the effect aldosterone has on the distal convoluted tubule?

Aldosterone acts on the distal tubule to retain sodium and excrete potassium by inhibition of sodium-potassium exchange (see Fig. 5-4). Water is retained with sodium. In heart failure, plasma aldosterone rises up to 20 times normal in response to increased angiotensin II coupled with decreased hepatic clearance.

Where does the filtrate go from the distal convoluted tubule?

Once the filtrate passes through the thick ascending limb of Henle, it enters the distal convoluted tubule, which is a duct of the renal tubule located in the kidney’s cortex that reabsorbs calcium, sodium, and chloride and regulates the pH of urine by secreting protons and absorbing bicarbonate.

Which hormone inhibits the reabsorption of sodium and water at the distal convoluted tubule?

atrial natriuretic peptide (ANP)This hormone, called atrial natriuretic peptide (ANP), exerts a vasodilator effect on the kidney and also reduces tubular reabsorption of sodium. Both actions result in increased urinary elimination of salt and water and tend to restore atrial pressure toward the normal.

Which hormone causes the decrease in the water content in the distal convoluted tubule?

ADHWhich hormone causes the decrease in the water content in the distal convoluted tubule? ADH; (ADH constantly regulates and balances the amount of water in your blood.It tells your kidneys how much water to conserve.)

What is the main function of distal convoluted tubule?

A distal convoluted tubule connects to the collecting duct system that fine-tunes salt and water reabsorption and plays a major role in acid–base balance. The initial segment of the collecting duct, the cortical collecting duct, takes off from the distal convoluted tubule in the cortex.

How reabsorption occurs in the distal convoluted tubule?

Reabsorption in the distal tubule and collecting duct: The tubular fluid now enters the distal tubule and collecting duct, or terminal nephron. … Sodium reabsorption in the late distal tubule and collecting duct is regulated by hormones, which stimulate or inhibit sodium reabsorption as necessary.

What is the primary function of the distal convoluted tubule and collecting duct?

The distal convoluted tubule (DCT) and collecting duct (CD) are the final two segments of the kidney nephron. They have an important role in the absorption of many ions, and in water reabsorption.

Where is the distal convoluted tubule located?

Section of cortex of human kidney. The distal convoluted tubule (DCT) is a portion of kidney nephron between the loop of Henle and the collecting tubule.

Why is the distal convoluted tubule convoluted?

The distal convoluted tubule is the nephron segment that lies immediately downstream of the macula densa. Although short in length, the distal convoluted tubule plays a critical role in sodium, potassium, and divalent cation homeostasis.

What is the function of the distal convoluted tubule quizlet?

Freely permeable to water. Thick segment of ascending limb. What is the Distal Convoluted Tubule? DCT – Functions more in secretion than reabsorption.
