Module 1: Problem Set Question 1 0/0pts 1. There six levels of organization of the body- what are they? 2. The necessary life function that protects our internal environment from our external environment is provided by what system? 3. The function of movement is provided by what system? 4. The function of responsiveness is provided by what system? 5. The function of digestion is provided by what system? Your Answer: 1) Chemical, cellular, tissue, organ, organ system, organism level 2) Integumentary system. 3) Muscular system. 4) Nervous system. 5) Digestive system. 1. chemical level, cellular level, tissue level, organ level, organ system level, organism level. 2. Integumentary 3. muscular 4. Nervous 5. Digestive
Question 2 0/0 pts 6. What is anabolism? 7. What is catabolism? 8. Excretion involves what systems? 9. The reproductive system is controlled by what other system? 10. Which tissue covers the body surface and lines the cavities of the body. Your Answer: 6) The synthesis in living organisms of more complex substances from simpler ones. 7) Catabolism is the part of the metabolism responsible for breaking complex molecules down into smaller molecules. 8) Digestive, Respiratory system and Urinary system. 9) It is controlled from the Endocrine system by hormones. 10) Epithelial tissue. 6. making more complex cellular structures from simpler ones 7. Break down of complex cellular structures into simpler ones 8. digestive, respiratory and urinary 9. the endocrine system 10.Epithelium
Question 3 0/0 pts 11. Name the three steps in cellular respiration. 12. What is the purpose of ATP? 13. Epithelial cells perform what types of functions? 14. What are the four basic tissue types? 15. Review the figures in this lecture to recognize the major body systems. Your Answer: 11) Glycolysis, the Kreb's Cycle and the Electron Transport Chain. 12) ATP is typically main source of energy for almost most cellular processes. 13) Secretion, absorption and skin protection. 14) Epithelium, muscle, connective and nervous tissue. 11. Glycolysis, Citric Acid Cycle, Electron transport system 12. ATP is a very energy rich molecule the powers the cellular activities allowing cells to have the energy needed to carry out their functions. 13. The cells that make up epithelial tissue are specialized for tasks such as secretion and absorption. These cells are under constant cell division to replace dead cells that shed away. 14. The four basic tissue types in the human body are epithelium, muscle, connective and nervous tissue, each of which is made up of specific cell types that perform specific functions. 15. See module
Question 4 0/0pts 16. Toward or at the body surface is known as what direction? 17. Away from the body surface is what direction? 18. Between a more medial and more lateral structure is what orientation? 19. Toward or at the midline of the body or on the inner side of is what direction? 20. Away from the head end or toward the lower part of a structure of the body, is what direction? Your Answer: 16) Superficial. 17) Deep. 18) Intermediate. 19) Medial. 20) Inferior. 16.superficial 17. deep 18. intermediate 19. medial 20. inferior
Question 5 0/0pts 21. Toward the head end or upper part of a structure (above) is what direction? 22. Toward or at the front of the body is what direction? 23. Is the knee proximal or distal to the pelvis? 24. Is the elbow proximal or distal to the hand? 25. Toward or at the back of the body is what direction? Your Answer: 21) Superrior. 22) Ventral. 23) Distal. 24) Proximal. 25) Dorsal. 21. superior 22. ventral (anterior) 23. distal 24. proximal 25. Dorsal (posterior)
Question 6 0/0pts 26. Closing of a joint is which action? 27. Opening of a joint is which action? 28. In anatomical position are the hands in pronation or supination? 29. Why are the hands in this position (answer from #28/above)? 30. Define elevation and depression: Your Answer: 26) Flexion. 27) Extension. 28) Supination. 29) Because the radius and ulna are crossed when the arm is pronated and parallel when the arm is supinated. 30) The upward movement of the scapula and shoulder is elevation, while a downward movement is depression. 26. Flexion 27. Extension 28. Supination 29. Because the bones of the forearm (radius/ulna) are uncrossed in the supinated position 30. Elevation- upward movement of a structure Depression- downward movement of a structure
