Question 1 of 5
Is the following statement true: The anatomical position is lying down, as a cadaver would be positioned?
Correct Answer: B
Rationale: The correct answer is False. The anatomical position is a standardized way of describing the human body's orientation in a consistent manner. The anatomical position is standing upright, facing forward, with the arms at the sides and palms facing forward. This position serves as a reference point for anatomical descriptions and directional terms. Therefore, the statement that the anatomical position is lying down, as a cadaver would be positioned, is incorrect. Choice A is incorrect because the anatomical position is not lying down. Choices C and D are also incorrect as there is a definitive answer to the question.
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
The term 'physiology' is related to
Correct Answer: D
Rationale: The term 'physiology' originates from the Greek words 'physis' (meaning nature) and 'logos' (meaning study or relationship). Therefore, the correct answer is 'the Greek for 'relationship to nature.' Choice A is incorrect as it refers to the Latin meaning of 'physiology,' not the Greek origin. Choice B is incorrect as it is specific to the structure of internal organs, not the overall study of nature. Choice C is incorrect as it refers to a different term related to dissection or anatomy, not physiology.
Question 4 of 5
What causes wrinkled and sagging skin?
Correct Answer: C
Rationale: Wrinkled and sagging skin is primarily caused by the loss of subcutaneous fat and reduced levels of elastin and collagen in the skin. Choice A is incorrect as drinking too much water does not lead to wrinkled and sagging skin. Choice B is incorrect because heredity alone does not cause this condition. Excess subcutaneous fat, as mentioned in Choice D, can contribute to a different skin appearance, such as puffiness, but not wrinkled and sagging skin.
Question 5 of 5
Does the digestive system filter wastes from the blood?
Correct Answer: B
Rationale: The correct answer is False. The digestive system is responsible for breaking down food and absorbing nutrients, not filtering wastes from the blood. The excretory system, particularly the kidneys, filters wastes from the blood to form urine. Choices A, C, and D are incorrect because the digestive system's primary function is not waste filtration but rather digestion and absorption of nutrients.
