another endocrine glands , the thyroid gland ,secretes a hormone called thyroxine.This regulates the rate of many basic cell activities or metabolism.One way of determining the rate of metabolic activity is by measuring the amount of oxygen that the cells use.

Hormonal (endocrine) system
Endocrine glands make chemicals called hormones and pass them straight into the bloodstream. (Glands that pass their secretions down tubes or ducts to particular places are called 'exocrine glands'.) Hormones can be thought of as chemical messages. They communicate with the body and bring about changes. Usually, hormones take effect quite slowly. The endocrine system works with the nervous system and the immune system to help the body cope with different events and stresses.
A range of functions
Some of the roles of the endocrine system include:
How hormones work
A hormone will only act on a part of the body if it 'fits'. A hormone can be thought of as a 'key', and its target site (such as an organ) has specially shaped 'locks' on the cell walls. If the key (hormone) fits the lock (on the cell wall), then the hormone will work. The endocrine glands get feedback from the body so they can adjust the hormones and keep them at the right levels.
The glands
The glands of the endocrine system include:
Examples of exocrine glands
Glands that secrete straight to a target site via ducts or tubes are called exocrine glands. Some examples include:
Common problems

The nervous system and endocrine system work very much hand in hand.

The endocrine system works with all of the other systems, including the nervous system, digestive system, and circulatory system. In the nervous system, the endocrine system sends hormones to cells.
Endocrine system and nervous system work along with each other and they control each other.
The endocrine and excretory systems work together.

The endocrine system releases cortisol with can make substances that increase your immunity.
Hormones.
Tissue function is regulated by hormones and the endocrine system is in charge of all the hormones in your body.
The endocrine system works with all of the other systems, including the nervous system, digestive system, and circulatory system. In the nervous system, the endocrine system sends hormones to cells.
The endocrine system causes the release of digestive hormones. The digestive tract also signals the endocrine system as to the presence of food.
Endocrine system and nervous system work along with each other and they control each other.
The Endocrine system consists of the glands such as the pituitary gland, thyroid gland, the adrenal glands, and the testes and the ovaries, which all secrete hormones. The thyroid gland does not work with the endocrine system, this system is simply a title of the glands named above.
the diestive system provides the energy and nutrition that the endocrine system uses and regulates. the endocrine system in turn regulates the digestive system by producing hormones such as insulin that help metabalize foods and nutrients.
