ATI Anatomy and Physiology Online Practice
1. Specialized cell types organized in a way that provides a specific function form
- A. tissues, which build organs.
- B. organs, which build tissues.
- C. organ systems, which build tissues.
- D. atoms, which comprise tissues.
Correct answer: A
Rationale: The correct answer is 'tissues, which build organs.' Specialized cell types organize to form tissues, which in turn build organs. Tissues are groups of cells that work together to perform a specific function. Option B is incorrect because organs are composed of tissues, not the other way around. Option C is incorrect as organ systems consist of multiple organs working together, not building tissues. Option D is incorrect as atoms are the basic building blocks of matter and are not directly involved in forming tissues.
2. Metabolism refers to all of the chemical reactions in an organism that support life. Is this statement true?
- A. True
- B. False
- C. Not Sure
- D. None of the above
Correct answer: A
Rationale: The statement is true. Metabolism indeed refers to all of the chemical reactions in an organism that support life. It is essential for various processes in the body, including converting food into energy, building and repairing tissues, and eliminating waste products. Choice B is incorrect because metabolism does encompass all chemical reactions that sustain life. Choice C is incorrect as the definition of metabolism is clear. Choice D is incorrect as the statement provided is true.
3. Is the parietal pleura a visceral membrane?
- A. TRUE
- B. FALSE
- C. Not Sure
- D. None of the above
Correct answer: B
Rationale: The statement that the parietal pleura is a visceral membrane is false. The parietal pleura is actually a membrane that lines the thoracic cavity and is responsible for protecting and cushioning the lungs. Visceral pleura, on the other hand, is the membrane that covers the surface of the lungs. Therefore, the parietal pleura is not a visceral membrane, making the correct answer 'False.' Choices C and D are not relevant as the question is asking for a true/false statement.
4. The origin of the term 'anatomy' is related to
- A. the Greek word for 'function.'
- B. the name of the first anatomist.
- C. the Greek word for 'cutting up.'
- D. the function of internal organs.
Correct answer: C
Rationale: The correct answer is C: the Greek word for 'cutting up.' The term 'anatomy' originates from the Greek words 'ana' (up) and 'temnein' (to cut), which means 'cutting up' or 'dissection.' This term refers to the process of dissecting bodies to study their structure. Choices A, B, and D are incorrect because 'anatomy' is not related to the Greek word for 'function,' the name of the first anatomist, or the function of internal organs, but rather to the act of cutting up for study and examination.
5. Which of the following lists best illustrates the idea of increasing levels of complexity?
- A. Cells, tissues, organelles, organs, organ systems
- B. Tissues, cells, organs, organelles, organ systems
- C. Organs, organelles, organ systems, cells, tissues
- D. Organelles, cells, tissues, organs, organ systems
Correct answer: D
Rationale: The correct answer is D: Organelles, cells, tissues, organs, organ systems. This list correctly depicts the increasing levels of complexity in biological organization. It starts with organelles, which are subunits within cells, followed by cells, then tissues (groups of cells working together), organs (comprised of different tissues), and finally organ systems (multiple organs working together). Choices A, B, and C are incorrect as they do not follow the logical progression of complexity from smaller units to larger, more complex structures.
