What does the respiratory system to the circulatory system?

Answer 1

IN THE RESPIRATORY SYSTEM;

• The cilia are killed bcoz tar is present in smoke. This combines with the mucus layer and the place which produce mucus will be blocked because they can't be moved (cilia moves them). This may cause breathing difficulty.
• Smoke damages the walls of the alveoli, which breakdown and fuse together again. This reduces the surface area for gas exchange and gases can't easily pass through these damaged walls. This causes lung diseases - Emphysema.

THE CIRCULATORY SYSTEM;

• CO2 combines with hemoglobin and forms carboxyhemoglobin which reduces the ability for oxygen to combine with hemoglobin. Therefore, the tissues become starved of oxygen.

Note By; Nicotine vapor affects the nervous system, causing the rising of blood pressure. This may also cause lung cancer and heart attack.
