Homeostatic Mechanisms
Biology ⇒ Biological Systems and Homeostasis
Homeostatic Mechanisms starts at 7 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Homeostatic Mechanisms.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 8
A person is exposed to cold weather and starts to shiver. What is the purpose of shivering in this context?
Describe how sweating helps maintain homeostasis.
Describe how the body maintains blood pressure within a normal range.
Describe the role of the kidneys in homeostasis.
Explain how the body responds when blood sugar levels rise after eating.
A person eats a salty meal. How does the body respond to maintain water balance? (1) Increases urine output (2) Decreases urine output (3) Increases sweating (4) Decreases breathing rate

Fill in the blank: The __________ is the part of the brain that acts as the main control center for homeostasis.
Fill in the blank: The __________ system transports hormones and nutrients to help maintain homeostasis.
Fill in the blank: The __________ system works with the nervous system to regulate homeostasis by releasing hormones.
Fill in the blank: The hormone __________ is released when blood sugar is too low.
Homeostasis helps organisms survive in changing environments. True or False?
True or False: Homeostasis only involves the nervous system.
True or False: Homeostatic mechanisms can involve both behavioral and physiological responses.
True or False: Homeostatic mechanisms only occur in animals, not in plants.
