Cilia: tiny hairs that help clean out dirt particles out ofthe lungs.
If the cilia stop functioning because of smoking they willnot be able to fight infections.

• Mimics neurotransmitters
• Decreases some reflex actions
• Activates the brain’s“reward pathway”
Cardiovascular System
• Increases heart rate and theforce of contractions
• Increases blood pressure
• Reduces blood flow to skin
• Increases risk ofblood clotting
Digestive System
• Increases saliva production
• Decreases the amount ofinsulin released from thepancreas
• Increases bowel activity
Respiratory System
• Increases mucusproduction
• Decreases muscle actionin the lungs’ airways
• Causes breathing tobecome more shallow
