Question 1 of 5
What is the main function of the digestive system?
Correct Answer: C
Rationale: The correct answer is C: Absorption of nutrients. The main function of the digestive system is to break down food into nutrients that can be absorbed by the body. Choice A, 'Formation of cells,' is incorrect as cell formation is not the primary function of the digestive system. Choice B, 'Movement of body parts,' is incorrect as this is more related to the muscular system. Choice D, 'Providing oxygen for the extraction of energy from nutrients,' is incorrect because providing oxygen is primarily the function of the respiratory system, not the digestive system.
Question 2 of 5
Paired organs, such as the kidneys or lungs, are said to be
Correct Answer: C
Rationale: The correct answer is C: 'bilateral.' Paired organs like the kidneys or lungs are described as bilateral because they occur in pairs on both sides of the body. Option A 'bisexual' refers to having both male and female reproductive organs, which is not the correct term for paired organs. Option B 'bilingual' refers to being able to speak two languages, which is not related to the description of paired organs. Option D 'bivalent' means having two valences, which is also unrelated to the context of paired organs.
Question 3 of 5
Do patterns of growth in preserved bones and tooth decay reflect the health of the people they were a part of?
Correct Answer: A
Rationale: Patterns of growth in preserved bones and tooth decay can indeed reflect the health of the individuals they belonged to. Growth patterns can indicate malnutrition or diseases during childhood, while tooth decay can signify dietary habits and overall health. Therefore, the correct answer is 'Yes.' 'No' is incorrect because these factors can provide valuable information about the health of individuals. 'Not enough information to determine' is incorrect as these indicators are commonly used in anthropological and archaeological studies to understand health conditions in past populations. 'Not applicable' is also incorrect as the information from bones and tooth decay is relevant to assessing the health of individuals.
Question 4 of 5
In the early days, healers transitioned from superstition and magic to using natural chemicals in the field of medicine.
Correct Answer: A
Rationale: The statement is true. The field of medicine evolved as early healers moved away from superstition and magic, instead focusing on natural chemicals to treat illnesses. This transition marked a shift towards a more scientific and evidence-based approach to healthcare. Choice B is incorrect because the statement accurately reflects the historical development of medicine. Choice C is incorrect as the historical transition from superstition to natural chemicals is a well-documented aspect of the evolution of medicine. Choice D is incorrect as the statement provided is true.
Question 5 of 5
The anatomy of a body part is closely related to its physiology.
Correct Answer: A
Rationale: The statement is true. Anatomy and physiology are interconnected fields. Anatomy focuses on the structure of body parts, while physiology deals with the functions of those parts. Understanding the structure (anatomy) of a body part is crucial in comprehending how it functions (physiology). This interrelation is essential for healthcare professionals to diagnose and treat medical conditions effectively. Choice B is incorrect because anatomy and physiology are indeed closely related. Choice C is incorrect as well because the relationship between anatomy and physiology is a fundamental concept in the study of the human body. Choice D is incorrect as the statement is true.
