Answer #1

Autonomic nervous system classified into sympathetic and parasympathetic nervous system.

Under sympathetic:

1. Heart- Increases heart rate and force of contraction

2. Blood vessels- vasoconstriction

3. Lung- bronchodilation

4. GIT- reduces motility and secretions, cause sphincter contraction.

5. Pupils- dilates

6. Muscle- Increases blood flow to skeletal muscles.

Under parasympathetic:

1. Heart- reduces heart rate and force of contraction

2. No effect on blood vessels

3. Bronchoconstriction

4. Increases motility and secretions, sphincter relaxation.

5. Constricts pupils.

6. Reduces blood flow to skeletal muscle
