The system of the body that coordinates and controls its activities is known as the nervous system. The nervous system is a complex network of specialized cells called neurons that transmit electrical and chemical signals throughout the body. It is responsible for receiving sensory information, processing and integrating that information, and initiating appropriate responses or actions.
The nervous system is involved in controlling and coordinating various functions, including movement, sensation, perception, thinking, memory, and the regulation of vital bodily processes such as heart rate, breathing, digestion, and hormone release. It works in conjunction with other organ systems (option A), such as the muscular system (option B), to enable coordinated movement and bodily functions.
Nervous tissue (option C) is a component of the nervous system, consisting of specialized cells (neurons and glial cells) that make up the structure and function of the nervous system. However, the nervous system as a whole is responsible for coordinating and controlling the body's activities.
