FAQs on Human Excretory System Video Lecture - NEET
| 1. What is the function of the human excretory system? |  |
Ans. The human excretory system is responsible for removing waste products from the body. Its main functions include filtering blood to remove waste substances, regulating the balance of electrolytes and fluids, and producing urine to eliminate excess water, toxins, and metabolic byproducts.
| 2. How does the human excretory system maintain electrolyte balance? | |
Ans. The human excretory system maintains electrolyte balance through the kidneys, which filter blood and regulate the reabsorption and excretion of electrolytes such as sodium, potassium, calcium, and chloride. The kidneys ensure that the proper levels of these electrolytes are maintained in the bloodstream, which is essential for various bodily functions.
| 3. What is the role of the kidneys in the human excretory system? | |
Ans. The kidneys play a crucial role in the human excretory system. They filter waste products and excess water from the blood, regulate electrolyte balance, and help control blood pressure. Additionally, the kidneys produce hormones like erythropoietin, which stimulates red blood cell production, and renin, which helps regulate blood pressure.
| 4. How does the human excretory system eliminate waste products? | |
Ans. The human excretory system eliminates waste products primarily through urine formation and excretion. The kidneys filter waste substances, such as urea and uric acid, from the blood and convert them into urine. The urine then travels through the ureters to the bladder, where it is stored until it is eliminated from the body through the urethra.
| 5. How does the human excretory system help maintain fluid balance? | |
Ans. The human excretory system helps maintain fluid balance by regulating the amount of water reabsorbed by the kidneys. When the body needs to conserve water, the kidneys decrease urine production and reabsorb more water back into the bloodstream. Conversely, when the body needs to eliminate excess water, the kidneys increase urine production, thus helping to maintain fluid balance.
