Describe the coordination and regulations of the body?

In order to survive a wide range of environmental conditions, the human body must be able to detect and respond to changes

The maintenance of a constant internal environment within tolerable limits is called homeostasis and is regulated by negative feedback

Two main body systems coordinate homeostatic regulation - the nervous system and the endocrine system

The nervous system and the endocrine system regulate and coordinate body functions by sharing in a unique partnership. Jointly they maintain growth, maturation, reproduction, metabolism and human behavior.

The hypothalamus of the brain (a part of the nervous system) sends directions via chemical signals to the pituitary gland (a part of the endocrine system). The pituitary is occasionally referred to as the master gland of the system, because many of its hormones stimulate the other endocrine glands to secrete their hormones.

All these hormones along with signals from nervous system regulate our body homeostasis and functions.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
