____ is a vital link between blood and tissues by which essential substances pass from blood to cells and excretory products from cells to blood.
- Lymph
- Heart
- Arteries
- Veins
The Correct Option is A
Solution and Explanation
To solve this question, we need to identify the structure that serves as a vital link between blood and tissues for the exchange of essential substances and excretory products.
1. Understanding the Given Options:
- Lymph: A fluid similar to plasma that transports substances between blood and tissues, and helps in removal of waste and immunity.
- Heart: Pumps blood through vessels but does not directly exchange substances with tissues.
- Arteries: Carry oxygenated blood from the heart to tissues but do not directly exchange substances at tissue level.
- Veins: Carry deoxygenated blood back to the heart but also do not directly exchange substances at tissue level.
2. Identifying the Correct Answer:
The structure described, acting as a crucial link between blood and tissues and facilitating exchange of nutrients, oxygen, and waste products, is the lymph.
Final Answer:
Option (A) Lymph is correct.
