- 7. TYPE TRUE OR TYPE FALSE (SPELLING MATTERS): - - - Connective tissue supports and links other parts of the body. It includes bone, cartilage, tendons, ligaments, and blood. These tissues provide strength, structure, and flexibility where the body needs it most. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - True or False: Blood is classified as a type of connective tissue.
- 8. TYPE TRUE OR TYPE FALSE (SPELLING MATTERS): - - - Muscle tissue is made of long fibers that can contract and relax. This tissue allows you to move your arms, legs, and even your heart. There are three types: skeletal, smooth, and cardiac muscle. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - True or False: There is only one kind of muscle tissue in the human body.
- 9. TYPE TRUE OR TYPE FALSE (SPELLING MATTERS): - - - Nerve tissue controls communication in the body. It includes the brain, spinal cord, and nerves. This tissue uses electrical and chemical signals to carry information throughout your body. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - True or False: Nervous tissue helps the body send and receive information
- 10. TYPE TRUE OR TYPE FALSE (SPELLING MATTERS): - - - No single tissue can do all the work of life. When two or more tissues join together, they create an organ—a structure that performs a special task. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - True or False: An organ is made from only one kind of tissue.
- 11. TYPE TRUE OR TYPE FALSE (SPELLING MATTERS): - - -The heart is an organ made of several tissue types. Muscle tissue makes it pump blood. Connective tissue strengthens its walls. Nervous tissue controls its rhythm, and epithelial tissue lines the inner chambers. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - True or False: The heart is made only of muscle tissue.
- 12. TYPE TRUE OR TYPE FALSE (SPELLING MATTERS): - - - Each organ in your body has a specific function that contributes to keeping you alive. Your stomach digests food, your lungs exchange gases, and your kidneys filter waste. Together, these organs make up complete systems. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - True or False: All organs in the body perform the same type of job
- 13. TYPE TRUE OR TYPE FALSE (SPELLING MATTERS): - - -When organs work together to perform related tasks, they form an organ system. For example, the cardiovascular system includes the heart, blood, and blood vessels. These organs cooperate to circulate blood throughout the body. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - True or False: The heart and blood vessels are part of the cardiovascular system.
- 14. TYPE TRUE OR TYPE FALSE (SPELLING MATTERS): - - -Each organ system has a specific job that helps the body stay balanced. The digestive system breaks down food, the respiratory system brings in oxygen, and the urinary system removes waste. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - True or False: The urinary system’s main job is to transport oxygen to the brain.
- 15. TYPE TRUE OR TYPE FALSE (SPELLING MATTERS): - - -All of your body’s organ systems work together to keep your health. If even one system fails, other systems are affected and that would affect your health. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - True or False: The human body can function perfectly even if one major organ system fails.
- 16. TYPE TRUE OR TYPE FALSE (SPELLING MATTERS): - - -The levels of organization in the human body are: cell → tissue → organ → organ system → organism. Each level builds upon the one before it, forming the structure of life. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - True or False: The correct order of organization in the body ends with the cell
- 17. TYPE TRUE OR TYPE FALSE (SPELLING MATTERS): - - -There are four major types of tissue—epithelial, connective, muscle, and nervous. Together, they form the organs and systems that keep you alive and healthy. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - True or False: Muscle tissue helps move the body and even pumps the heart
- 18. TYPE TRUE OR TYPE FALSE (SPELLING MATTERS): - - -All of your systems must work together as one unified organism. This constant teamwork keeps every part of your body functioning in balance. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - True or False: The systems of the human body function independently without needing each other.
