Science 5

• 1. Moves oxygen from the outside into the body
• 2. Moves carbon dioxide and water from the body

Glucose is broken down using oxygen to produce energy.

Movement of hair into and out of lungs.

• Digestive system-absorbs glucose from food
• Circulatory system-carries oxygen from your lungs and glucose from your food to your cells

Only 21% is air and the rest is nitregin.

• Nicitine
• Carbon Minoxide

• Nose
• Pharinx
• Tracea
• Bronci

It helps remove the trapped particles.

• It warms and moistens the air you breath in.
• Traps the particles

Air moves from nose into throat which is also used for food.

• Leads from the pharinx to the lungs
• Rings of cartlige keep it open
• Epiglottis keeps food from getting into the tracea

• Air enters alviolis
• Oxygen passes through the wall of the aviolis
• And then through the capillary wall into the blood
• Carbin Dioxide and water pass from the blood into the avioli.

• The bronchi directs air into the lungs
• It divides into smaller tubes like tree branches
• At the end of the tubes are alveoli, which look like grapes
• Part of each bronchus is outside the lung and part is inside

Tiny sacs of lung tissue specialized for the movement of gases between air and blood. They are surrounded by capillaries where the blood picks up oxygen from the air..

Large surface area of alveoli. 300 million in an adult

• The Rib Muscles
• Diaphragm

• 2 vocal cords in your larninx
• When the vocal cords vibrite
• Shorter=higher voice
• Longer=lower voice

The chest cavity becomes larger making more room for air and decreasing the air pressure inside the lungs. Because of the difference in air pressure, air rushes into your chest.

• Sneezes occur in the nose
• Coughs occur in the trachea
• They act to remove irritating paricles

• Increase in breathing and heart rate due to carbon monoxide in smoke
• Damage to protetctive cilia and risk of cancer due to tar
• Addiction and increase in blood pressure due to nicotine
• Risk of chronic bronchitis, emphysema, lung cancer and atherosclerosis

• Tar
• Carbon Monoxide
• Nicotine

• Chronic bronchitis - irritation of breathing passages
• Emphysema - destroys lung tissue, cannot get enough oxygen or eliminate enough carbon dioxide
• Lung cancer - chemicals cause tumors

• Atherosclerosis - chemicals get into blood vessels and cause buildup
• Smokers are twice as likely to have a heart attack
• If either the circulatory or respiratory system is damaged, the other one has to work even harder.

Causes respiratory problems from breathing in smoke from other people.

• Collects waste produced by cells and removes the wastes from the body.
• Helps maintain homeostasis by removing harmful materials that would make you sick if they stay in the body.

• Water
• Carbon dioxide
• Urea - peeeeee!

• Kidney
• Ureter
• Bladder
• Urethra

Nephrons - filter the blood

• Waste and glucose are removed from blood
• Glucose is returned to blood
• Wastes move into capsule
• Urine remains in the capsule

Regulate amount of water in your body

• Skin - sweat
• Lungs - exhale Carbon dioxide and water
• Liver - breaks down proteins
