Homeostasis Flashcards
What is homeostasis?
Homeostasis is the body’s ability to maintain a stable internal environment in response to changing external conditions.
What is the role of homeostasis in the body?
Homeostasis is essential for maintaining the body’s normal physiological processes, such as temperature, respiration, digestion, and metabolism.
What are the components of homeostasis?
The components of homeostasis include inputs, control mechanisms, outputs, and feedback loops.
What is the difference between homeostasis and equilibrium?
Homeostasis is the maintenance of a relatively constant internal environment, while equilibrium is the state of balance between opposing forces.
What is the role of feedback in homeostasis?
Feedback is essential for homeostasis, as it allows the body to detect and respond to changes in the internal environment.
What is negative feedback?
Negative feedback is a mechanism in which a change in the output of a system triggers a response in the input of the system that reverses the direction of the change.
What is positive feedback?
Positive feedback is a mechanism in which a change in the output of a system triggers a response in the input of the system that amplifies the direction of the change.
What is the role of the endocrine system in homeostasis?
The endocrine system is responsible for secreting hormones that regulate the body’s physiological processes, such as metabolism, growth, and reproduction.
How does the hypothalamus regulate homeostasis?
The hypothalamus regulates homeostasis by sensing changes in the body’s internal environment and triggering responses in the endocrine system to maintain a stable internal environment.
What are the hormones involved in homeostasis?
The hormones involved in homeostasis include adrenaline, cortisol, thyroid hormones, and antidiuretic hormone.
What is the role of glucose in homeostasis?
Glucose is necessary for the body to maintain its internal environment, as it is the primary source of energy for the body’s cells.
What is the role of electrolytes in homeostasis?
Electrolytes are necessary for the body to maintain its internal environment, as they are involved in the regulation of body fluids.
What is the role of temperature in homeostasis?
Temperature is necessary for the body to maintain its internal environment, as it affects the body’s metabolic processes.
Why is the maintenance of pH important for homeostasis?
The maintenance of pH is important for homeostasis, as it affects the body’s biochemical processes.
What are the body’s mechanisms for maintaining homeostasis?
The body’s mechanisms for maintaining homeostasis include negative and positive feedback loops, hormones, and enzymes.
