What are some of the roles of the central nervous system? Select all correct answers. A. Receives Information from outside the body through the senses B. Controls heart rate C. Helps fight infection from pathogens D. Reacts to the environment by activating an appropriate response

## Step 1<br />The central nervous system (CNS) is a part of the nervous system that includes the brain and spinal cord. It is responsible for receiving information from the outside world through the senses, controlling heart rate, and reacting to the environment by activating an appropriate response.<br /><br />## Step 2<br />Option A states that the CNS receives information from outside the body through the senses. This is correct as the CNS receives sensory information from the body and processes it.<br /><br />## Step 3<br />Option B states that the CNS controls heart rate. This is also correct as the CNS regulates the heart rate.<br /><br />## Step 4<br />Option C states that the CNS helps fight infection from pathogens. This is not correct as the immune system, not the CNS, is responsible for fighting infections.<br /><br />## Step 5<br />Option D states that the CNS reacts to the environment by activating an appropriate response. This is correct as the CNS processes sensory information and initiates appropriate responses.
