Multiple Choice

Which of the following statements is true regarding the role of homeostasis in the human body?

Homeostasis is the process by which the body increases its internal temperature in response to cold environments.

Homeostasis involves maintaining a stable internal environment despite external changes.

Homeostasis is primarily responsible for the digestion of food in the gastrointestinal tract.

Homeostasis only occurs in the nervous system and is unrelated to other body systems.

Verified step by step guidance

Understand the concept of homeostasis: Homeostasis is the process by which the body maintains a stable internal environment despite changes in external conditions. This involves various physiological mechanisms that regulate factors such as temperature, pH, and electrolyte balance.

Evaluate the first statement: 'Homeostasis is the process by which the body increases its internal temperature in response to cold environments.' This statement is partially true as it describes a specific response (thermoregulation) but does not encompass the full scope of homeostasis.

Evaluate the second statement: 'Homeostasis involves maintaining a stable internal environment despite external changes.' This statement accurately describes the overall role of homeostasis in the human body.

Evaluate the third statement: 'Homeostasis is primarily responsible for the digestion of food in the gastrointestinal tract.' This statement is incorrect as digestion is a specific physiological process, while homeostasis refers to the broader regulation of the body's internal environment.

Evaluate the fourth statement: 'Homeostasis only occurs in the nervous system and is unrelated to other body systems.' This statement is incorrect because homeostasis involves multiple body systems, including the endocrine, respiratory, and circulatory systems, working together to maintain balance.
