To Be Able To List Diseases Caused By Smoking And To Be Able To Define Diffusion
What is Diffusion?
Diffusion is the net movement of molecules or ions. It is the movement from a high concentration to a low concentration. Until dynamic equilibrium is reached. This is a passive process.
Describe the gas exchange at the alveolus in terms of Diffusion.
In the alveoli there is a high amount of Oxygen concentration than in the blood due to Oxygen being used by body tissues so the Oxygen diffuses into the blood where its concentration is the lowest however Carbon Dioxide has a higher concentration in the blood due to cellular respiration so Carbon Dioxide diffuses into the alveoli’s and both gases will diffuse until dynamic equilibrium is reached.
What are some of the diseases caused by Smoking?
Some of the diseases caused by Smoking are Lung Cancer, Heart Disease, Type Two Diabetes, Stroke, and Emphysema.
What are the Chemicals in Cigarette Smoke?
The Chemicals in Cigarette Smoke are Nicotine, Tar, Carbon Monoxide, Lead, Arsenic, and Ammonia.
What are the effects of the Chemicals in cigarette smoke on the body?
Nicotine is an addictive substance that stimulates the central nervous system, Tar has a mixture of various chemicals that can cause lung damage and cancer, Carbon Monoxide is a poisonous gas that reduces the Oxygen carrying capacity of the blood, Lead is a heavy metal that can accumulate in the body and cause neurological damage, Arsenic is a toxic element that increases the risk of cancer and other health problems, and Ammonia is a chemical used in cleaning products that can irritate the respiratory system.
