FAQs on Excretory System Video Lecture - Class 6 All Subjects (Old NCERT)

1. What are the main organs involved in the excretory system?
Ans. The main organs involved in the excretory system include the kidneys, ureters, bladder, and urethra. The kidneys filter blood to produce urine, which is then transported through the ureters to the bladder, where it is stored until excretion through the urethra.
2. How do the kidneys function in the excretory system?
Ans. The kidneys function by filtering blood to remove waste products and excess substances, such as water, salts, and toxins. They perform this filtration through nephrons, which are the functional units of the kidneys. The filtered waste forms urine, which is then excreted from the body.
3. What is the role of the bladder in the excretory system?
Ans. The bladder's role in the excretory system is to store urine until it is ready to be excreted from the body. It has elastic walls that expand as it fills with urine and contract during urination to release urine through the urethra.
4. What are common disorders related to the excretory system?
Ans. Common disorders related to the excretory system include urinary tract infections (UTIs), kidney stones, chronic kidney disease, and bladder infections. These conditions can affect the functioning of the excretory organs and lead to various symptoms, such as pain, frequent urination, or blood in the urine.
5. How can one maintain a healthy excretory system?
Ans. To maintain a healthy excretory system, it is important to stay hydrated, eat a balanced diet rich in fruits and vegetables, limit salt intake, and avoid excessive consumption of alcohol and caffeine. Regular exercise and practicing good hygiene can also support overall urinary health.
