Regulation of Kidney
1. What do you mean by Kidneys ?
Answer:
There are two Kidneys in a human body which are located in the either side of the spine below the rib cage which are used to filter the waste materials out of the blood and then pass them out of the body in the form of urine.
2. What is the role of Hypothalamus in the regulation kidney function?
Answer:
Whenever there is the change in the volume of blood or in the ionic concentration or if there is loss of excessive fluids the hypothalamus is activated and releases ADH which further stimulates reabsorption of water.
3. Which hormones are used for the regulation of Kidneys function ?
Answer:
The regulation is done by some hormones such as – the hypothalamus regulation which includes ADH and ANP, the Juxtaglomerular Apparatus (JGA) and to some extent, the heart.
4. What is the role of Renin-Angiotensin mechanism in kidney function ?
Answer:
Whenever the blood flow in the glomerulus decreases, renin is released from the juxtaglomerular cells which causes increase in the glomerular blood pressure of GFR. Therefore, the regulation of Juxtaglomerular Apparatus is called as Renin-Angiotensin mechanism.
5. What is the role of kidney in excretion ?
Answer:
Kidneys are the excretory organs in human body which are used for the excretion of urea in the form of urine. The function of kidneys are monitored and regulated by feedback mechanism.
6. What are the main hormone which controls the kidney ?
Answer:
The three main hormones which controls the kidney are- Antidiuretic hormone, Atrial natriuretic peptide and the renin aldosterone.
Regulation of Kidney Function Notes Class 11
The Kidneys which are present in the human body are responsible for multiple functions in humans which include the formation of urine, water metabolism, ionic balance, and regulation of blood pressure. Therefore with the help of these kidneys, the wastes are being removed from human body. These kidneys are responsible for regulating water balance in human beings and also filtering waste and excess of these fluids from the blood.
