and special sense organs such as eyes and ears
Functions:
1.) generates action potentials to regulate body internal an external environments
2.) interprets change

Functions and components of the ENDOCRINE system - ✔✔Components: hormone-producing glands
(pineal gland, hypothalamus, pituitary gland, thymus, thyroid gland, parathyroid gland, adrenal
glands, pancreas, ovaries, testes) and hormone-producing cells in several organs
Functions: Regulates body activities by releasing hormones (chemical messengers transported in
blood from endocrine gland or tissue to target organ
,Functions and components of the CARDIOVASCULAR system - ✔✔Components: blood, heart, and
blood vessels
Functions:
