Q1. Answer the following sub-questions:
- A) Define tissue and classify the four primary types of tissues found in the human body. (250-300 words)
- B) Explain intercellular junctions with suitable examples. (250-300 words)
- Tissue: Group of similar cells and matrix performing specific function.
- Four primary tissues: Epithelial, Connective, Muscle, Nervous.
- Epithelial tissue covers surfaces, lines organs; protection, secretion, absorption.
- Connective tissue supports, binds, protects; diverse matrix, widely distributed.
Answer: The human body is an intricate biological system where cells are organized into functional units called tissues, which in turn form organs and organ systems. Tissues are fundamental to physiological processes, providing structure, protection, movement, and communication. Their integrity and function are maintained through specialized structures like intercellular junctions. Sub-question A: Tissues are defined by their specific cellular composition and extracellular matrix, working cooperatively...
