Control and coordination are important processes for living organisms that are brought about by the nervous system and the endocrine system. Control refers to the power of restraining and regulating a process, while coordination refers to the working together of different systems of an organism to produce an appropriate reaction to stimuli.

In humans, control and coordination take place through the nervous system and the endocrine system, which produce and secrete hormones. The nervous system consists of the brain, spinal cord, and nerves, and controls all the actions of the body. The five sense organs in the human body, eyes, ears, nose, tongue, and skin, are called receptors and function by receiving information from the environment around us. The response and coordination in both humans and animals involve the sense organs, the nervous system, and hormones.

In multicellular organisms, specialized tissue is used for control and coordination activities. Control and coordination in animals are provided by nervous and muscular tissues, while chemical coordination is seen in both plants and animals. The nervous system is the system of conducting tissues that receives the stimulus and transmits it to other parts of the body forming a network. Hormonal control in animals is provided by hormones, which are biogenetic organic materials of low molecular weight secreted directly into the blood in very little amount showing distant effect acting indirectly through either cell organelles or the enzyme system.

In summary, control and coordination are essential for the proper functioning of an organism and the regulation of different functions of different systems. They are important for an organism to adapt to changes and perform important functions like metabolism, homeostasis, and more.
