| Question | Answer |
|---|---|
| What is the primary function of epithelial tissue in the body? | Epithelial tissue covers and lines body surfaces, cavities, and organs. It acts as a protective barrier and is involved in absorption, secretion, and sensation. |
| How do organs and organ systems work together in the human body? | Organs work together within organ systems to perform specific functions, like digestion (digestive system), circulation (circulatory system), and respiration (respiratory system), helping maintain homeostasis and overall body function. |
| What are the four major types of macromolecules essential for life? | Carbohydrates Lipids Proteins Nucleic Acids |
| What is the role of enzymes in biochemical reactions | Enzymes act as catalysts, speeding up chemical reactions by lowering the activation energy required, allowing vital biochemical processes to occur efficiently in the body. |
| What is the function of the mitochondria in a cell? | The mitochondria are the cell's powerhouses, converting nutrients into energy in the form of ATP, which is used to fuel cellular activities. |
| What is the main role of the cell membrane? | The cell membrane controls what enters and exits the cell, providing protection and maintaining homeostasis by regulating the movement of substances. |
| What are the four main tissue types in the human body? | The four main tissue types are: Epithelial tissue Connective tissue Muscle tissue Nervous tissue |
| What are the primary functions of the skin? | The skin provides protection from environmental damage, helps regulate body temperature, allows sensory perception, and plays a key role in vitamin D synthesis and immune defense. |
| What are the main types of skeletal tissues in the human body? | The main types of skeletal tissues are: Bone tissue (hard and supportive) Cartilage (flexible and smooth) Ligaments (connect bone to bone) Tendons (connect muscle to bone) |
| What are the two main parts of the human skeleton? | The two main parts of the human skeleton are: Axial skeleton (includes the skull, vertebral column, and rib cage) Appendicular skeleton (includes limbs and girdles) |
| What is the primary function of axial muscles? | Axial muscles primarily support and move the head, neck, and trunk, and help stabilize the vertebral column. |
| What is the primary function of appendicular muscles? | Appendicular muscles control the movement of the limbs and the girdles (shoulder and pelvic) that support the limbs, enabling actions like walking, running, and lifting. |
