What actions occur do to the sympathetic nervous system? decrease blood pressure Increase heart rate speed up digestion rest and digest

## Step 1<br />The sympathetic nervous system is a part of the autonomic nervous system, which is responsible for involuntary body functions. It is often referred to as the "fight or flight" system because it prepares the body for stressful or emergency situations.<br /><br />## Step 2<br />When the sympathetic nervous system is activated, it increases heart rate. This is because the heart needs to pump more blood to the muscles and other vital organs during stressful situations.<br /><br />## Step 3<br />The sympathetic nervous system also causes vasoconstriction, which is the narrowing of blood vessels. This leads to an increase in blood pressure, not a decrease.<br /><br />## Step 4<br />The sympathetic nervous system does not speed up digestion. In fact, it slows down digestion. This is because digestion is not a priority during stressful situations.<br /><br />## Step 5<br />The "rest and digest" functions are controlled by the parasympathetic nervous system, not the sympathetic nervous system. The parasympathetic nervous system is often referred to as the "rest and digest" system because it helps the body relax and recover after stressful situations.
