Quiz Questions Preview
Question 1
What is the primary focus of physiology?
Explanation
Physiology primarily focuses on understanding how living organisms and their components function.
Question 2
Which approach to physiology explains biological functions in terms of purpose?
Explanation
The teleological approach explains biological functions by focusing on their purpose or end goals.
Question 3
What does homeostasis refer to?
Explanation
Homeostasis refers to the processes that organisms use to maintain stable internal environments despite external changes.
Question 4
Who is credited with the concept of 'milieu intérieur' which relates to homeostasis?
Explanation
Claude Bernard is known for introducing the concept of 'milieu intérieur', which is foundational to the understanding of homeostasis.
Question 5
Which of the following is an example of a negative feedback control mechanism?
Explanation
Thermoregulation involving sweating is an example of negative feedback, as it helps lower body temperature when it rises.
Question 6
What does an intrinsic control mechanism refer to?
Explanation
An intrinsic control mechanism operates within an organ or system to regulate its functions without external influence.
Question 7
Which of the following is true about positive feedback control?
Explanation
Positive feedback control amplifies effects to achieve a specific outcome, such as the escalating contractions during childbirth.
Question 8
What best describes the role of feedback mechanisms in homeostasis?
Explanation
Feedback mechanisms play a crucial role in monitoring and adjusting physiological functions to uphold homeostasis.
Question 9
What is a major consequence of disruptions in homeostasis?
Explanation
Disruptions in homeostasis can lead to illness or disease as the body's systems are unable to function optimally.
Question 10
Which of the following best describes a negative feedback control mechanism in homeostasis?
Explanation
A negative feedback control mechanism stabilizes a system by counteracting deviations from a desired set point, helping to maintain homeostasis. In contrast, positive feedback amplifies changes, leading to further deviation.
