FAQs on Structure and Function of kidney Video Lecture - Class 9

1. What is the structure of the kidney?

Ans. The kidney is a bean-shaped organ located in the lower back of the body. It is made up of millions of tiny structures called nephrons, which filter waste products from the blood and produce urine.

2. What is the function of the kidney?

Ans. The main function of the kidney is to filter waste products and excess water from the blood to produce urine. It also helps regulate the levels of various substances in the body, such as electrolytes, pH, and blood pressure.

3. How does the kidney filter waste products?

Ans. The kidney filters waste products through a process called filtration. Blood enters the kidney through the renal artery, which then branches out into smaller blood vessels called capillaries. These capillaries surround the nephrons, and as blood passes through them, waste products are filtered out and collected in tiny tubules. The filtered blood is then returned to circulation, while the waste products are eventually excreted as urine.

4. What are the common kidney disorders?

Ans. Some common kidney disorders include kidney stones, urinary tract infections, kidney infections, kidney failure, and chronic kidney disease. These conditions can affect the normal functioning of the kidneys and may require medical intervention.

5. How can one maintain kidney health?

Ans. To maintain kidney health, it is important to stay hydrated by drinking plenty of water, maintain a balanced and healthy diet, limit the intake of salt and processed foods, exercise regularly, avoid smoking and excessive alcohol consumption, and manage chronic conditions such as diabetes and high blood pressure, as they can negatively impact kidney function. Regular check-ups with a healthcare professional are also recommended to monitor kidney health.
