3. Mouth/nose. Pharynx. Trachea. Bronchi. Bronchioles. Alveoli.

4. Veins have valves. Arteries carry Oxygenated blood. Veins carry deoxygenated blood.

5.plasma- transport the blood

Red blood cells -has hemoglobin which carries o2 from the lungs to the body. Then returns co2 from the body to the lungs

White blood cells -fight infection

Platelets- help with blood clotting

3. Air first enters your nose or mouth, then once inside the nasal cavity, the air passes through the nasal conchae. It is filtered, humidified, and warmed. It then goes to the pharynx, larynx, trachea, bronchi, bronchioles, then finally alveoli, where the oxygen is transferred into the blood in exchange for carbon dioxide.

4.
- Arteries carry blood away from the heart, veins carry blood to the heart.
- Veins are larger in diameter, which leads them to carry more blood than arteries.
- Veins are closer to the surface of the skin, whereas arteries are positioned more deeply in the body.

5.
1) Red blood cells: The transport oxygen from lungs to all living tissues of the body and carry carbon dioxide away.
2) White blood cells: Remove dead blood cells
3) Platelets: Clot blood
4) Plasma: Carries white cells, red cells, and platelets. Also provides nutrients.

Hope this helped! :)
