FAQs on Short Tricks: Excretory Products & their Elimination Video Lecture - Biology Class 11 - NEET
| 1. What are the excretory products in the human body? |  |
Ans. The excretory products in the human body include urea, uric acid, creatinine, ammonia, and carbon dioxide. These waste products are formed as a result of various metabolic processes in the body and need to be eliminated to maintain homeostasis.
| 2. How are excretory products eliminated from the body? | |
Ans. Excretory products are eliminated from the body through several organs and systems. The kidneys filter waste products from the blood and excrete them in the form of urine. The lungs eliminate carbon dioxide during exhalation. The skin excretes sweat, which contains metabolic waste products. The liver also plays a role in eliminating certain waste products through bile secretion.
| 3. What is the role of the kidneys in excretion? | |
Ans. The kidneys play a crucial role in the excretion of waste products. They filter the blood, removing metabolic waste products, excess water, and electrolytes. These filtered substances are then concentrated to form urine, which is excreted from the body. The kidneys also help regulate the pH and electrolyte balance in the body.
| 4. How does the urinary system eliminate waste products? | |
Ans. The urinary system, consisting of the kidneys, ureters, bladder, and urethra, eliminates waste products from the body. The kidneys filter waste products from the blood, which are then collected in the bladder as urine. When the bladder is full, urine is expelled from the body through the urethra during urination.
| 5. What happens if excretory products are not eliminated from the body? | |
Ans. If excretory products are not eliminated from the body, they can build up and lead to various health problems. Accumulation of waste products like urea and creatinine can cause kidney damage and renal failure. Retention of carbon dioxide can result in respiratory acidosis. Additionally, an imbalance in electrolytes and pH levels can disrupt normal bodily functions. Therefore, it is crucial for the excretory system to effectively eliminate waste products from the body.
