Q. Consider the following statements regarding Lymph:
1.It is a colorless fluid containing specialized lymphocytes responsible for immune responses.
2.It acts as a carrier for nutrients and hormones, returning interstitial fluid to the major veins.
3.Fats are absorbed directly into the blood capillaries of the intestinal villi rather than the lymphatic system.
Which of the statements given above is/are incorrect?
Answer: B
Notes:
Explanation:
- Statement 1 is correct: Lymph is a colorless fluid because it lacks red blood cells and hemoglobin. It contains specialized lymphocytes (B cells and T cells), which are central to the body’s immune responses by identifying and fighting foreign pathogens like bacteria and viruses.
- Statement 2 is correct: Lymph serves as a vital carrier for nutrients and hormones. It plays a key role in maintaining fluid balance by collecting interstitial fluid (the fluid that leaks out of blood capillaries into tissue spaces) and returning it to the major veins near the heart, thus preventing tissue swelling.
- Statement 3 is incorrect. Fats are too large to enter blood capillaries; they are absorbed through lacteals, which are specialized lymph vessels in the intestinal villi.
