Human endocrine System and Homeostasis

What is the human endocrine system?

The human endocrine system is a collection of glands that produce hormones, which regulate various bodily functions such as metabolism, growth and development, tissue function, sleep, and mood.

Name some major endocrine glands in the human body.

Major endocrine glands include the pituitary gland, thyroid gland, parathyroid glands, adrenal glands, pancreas, ovaries (in females), and testes (in males).

What are hormones and how do they function?

Hormones are chemical messengers produced by endocrine glands that travel through the bloodstream to target cells or organs, where they elicit specific responses. They regulate various physiological processes.

Define homeostasis.

Homeostasis is the ability of an organism to maintain a stable internal environment despite changes in external conditions. It involves a dynamic equilibrium of various physiological processes.

How does the endocrine system contribute to homeostasis?

The endocrine system plays a crucial role in maintaining homeostasis by producing and releasing hormones that regulate key physiological variables, such as blood glucose levels, blood pressure, body temperature, and electrolyte balance.
