The brain is responsible for
- thinking
- regulating the heart beat
- balancing the body
- all of the above
The Correct Option is D
Solution and Explanation
The human brain functions as the central command center of the nervous system, receiving information from the body's sensory organs and transmitting signals to the muscles. While sharing a basic structure with other animal brains, the human brain is comparatively larger than those of many mammals such as dolphins, whales, and elephants in relation to body size.
The brain, a complex organ, governs various functions including thought, memory, emotion, touch, motor skills, vision, breathing, temperature regulation, and hunger. It plays a multifaceted role in maintaining our ability to walk, talk, eat, as well as controlling essential physiological processes like breathing, blood circulation, and heart rate.
In summary, the brain is responsible for cognition, heartbeat regulation, and overall bodily balance.

Concepts Used:
Human Nervous System
The human nervous system is responsible for controlling and coordinating all the activities of the human body.
The three major functions of the human nervous system are:
- Gathering or assembling sensory information from the body and external environment.
- Processing and interpreting the sensory information acquired.
- Conveying or transferring appropriate response to the sensory information acquired.
The nervous system is mainly divided into two, namely:
The Central Nervous System (CNS) comprises the brain and spinal cord.
- The brain is majorly involved in the perception and processing of sensory input. It also regulates or manages voluntary motor responses and homeostatic mechanisms.
- The spinal cord act as a pathway for the transmission of information between the brain and the peripheral nervous system. It also takes action on reflex actions.
The Peripheral Nervous System (PNS) comprises sensory/motor neurons and ganglion.
Nervous System
The nervous system, often known as the neural system, is a sophisticated network of neurons dedicated to the transmission of messages. As we progress up the food chain, the neurological system becomes more sophisticated.
Functions of Nervous System:
The nervous system's most basic job is to govern the organism's movement and to influence the environment (e.g., through pheromones). This is accomplished by transmitting signals from one cell to another, or from one body component to another. Signals that travel to muscle cells cause muscles to contract, and signals that travel to endocrine cells cause hormones to be released into the circulation or other internal fluids to cause the nervous system's output.
