Which system releases hormones to regulate body functions in homeostasis?

• Endocrine system

• Nervous system

• Digestive system

• Respiratory system

What role does the pancreas play in maintaining homeostasis?

• Secretes insulin to lower blood sugar levels and glucagon to increase them.

• Regulates body temperature through vasodilation and vasoconstriction.

• Sends signals to organs to adjust their activities.

How do humans regulate body temperature when it becomes too hot?

• Vasodilation and sweating

• Vasoconstriction and shivering

• Releasing insulin and glucagon

• Opening and closing stomata

What is an example of homeostasis in plants?

• Regulating water loss through opening and closing stomata.

• Maintaining salt balance through specialized cells in gills.

• Generating heat to maintain body temperature.

• Releasing hormones to regulate body functions.
