FAQs on 4 Days Study Plan: Excretory Products and their Elimination - Biology Class 11 - NEET
| 1. What are nitrogenous wastes and why do they need to be eliminated from the body? |  |
Ans. Nitrogenous wastes are metabolic by-products that contain nitrogen, such as urea and ammonia. They are formed from the breakdown of proteins and nucleic acids in the body. These wastes are toxic and can disrupt normal cellular functions if they accumulate in the body. Therefore, it is essential to eliminate nitrogenous wastes to maintain proper physiological balance and prevent toxicity.
| 2. What is the counter current mechanism in the excretory system and how does it aid in urine formation? | |
Ans. The counter current mechanism is a process that occurs in the nephrons of the excretory system. It involves the flow of filtrate and blood in opposite directions within the nephron tubules. This mechanism plays a crucial role in urine formation by facilitating the reabsorption of water and important solutes, such as glucose and ions, back into the bloodstream.
| 3. How does the human excretory system work to eliminate waste products from the body? | |
Ans. The human excretory system consists of the kidneys, ureters, urinary bladder, and urethra. It functions to filter the blood and remove waste products, excess water, and toxins from the body. The kidneys filter the blood and produce urine, which is then transported to the urinary bladder through the ureters. The urinary bladder stores urine until it is eliminated from the body through the urethra during urination.
| 4. What are nephrons and what is their role in urine formation? | |
Ans. Nephrons are the functional units of the kidneys. They are responsible for the filtration, reabsorption, and secretion processes involved in urine formation. Each kidney contains millions of nephrons, which consist of a glomerulus, renal tubules, and associated blood vessels. The nephrons filter the blood, reabsorb essential substances, such as water and nutrients, and excrete waste products to generate urine.
| 5. What is the mechanism of urine formation in the nephrons of the human excretory system? | |
Ans. The mechanism of urine formation in the nephrons involves three main processes: filtration, reabsorption, and secretion. Filtration occurs at the glomerulus, where blood pressure forces water, ions, and small molecules to pass through the filtration membrane into the renal tubules. Reabsorption takes place in the renal tubules, where substances like water, glucose, amino acids, and ions are transported back into the bloodstream. Secretion involves the active transport of waste products, such as urea and drugs, from the bloodstream into the renal tubules for elimination in urine. These processes collectively contribute to the formation of urine in the nephrons.
