Autonomic Nervous System (ANS) Controls __ functions like heart rate and blood pressure Has two parts: 1. __ nervous system (SNS): speeds things up 2. __ nervous system (PNS): slows things down

## Step 1<br />The Autonomic Nervous System (ANS) is a part of the nervous system that controls involuntary body functions. These functions include heart rate and blood pressure, which are not consciously controlled but are essential for the body's functioning.<br /><br />## Step 2<br />The ANS is divided into two parts: the Sympathetic Nervous System (SNS) and the Parasympathetic Nervous System (PNS). <br /><br />## Step 3<br />The Sympathetic Nervous System (SNS) is responsible for speeding things up. This means it increases the heart rate and blood pressure, preparing the body for action.<br /><br />## Step 4<br />The Parasympathetic Nervous System (PNS), on the other hand, slows things down. This means it decreases the heart rate and blood pressure, helping the body to relax and recover.
