Smoking Effects on Health

assignment 3


COPD is a collection of lung diseases. People with COPD have difficulties breathing, primarily due to the narrowing of their airways, this is called airflow obstruction. Some symptoms of COPD is Increased breathlessness, Frequent coughing, Wheezing,Tightness in the chest. COPD is caused by cigarette smoke, Pipe, cigar, and other types of tobacco smoke also can cause COPD, especially if the smoke is inhaled. these are diseases than are caused by COPD, bronchitis' and 'emphysema'

Heart Disease

Smoking increases the risk of developing cardiovascular diseases, which includes coronary heart disease and stroke. Smoking damages your lining of your arteries and leading to a build up of fatty material atheroma which narrows the artery. This can cause angina, a heart attack or a stroke. The carbon monoxide in tobacco smoke reduces the amount of oxygen in your blood. The heart has to work much harder to pump blood around the body. Some symptoms are discomfort, pressure, heaviness, or pain in the chest, arm, or below the breastbone.

Yellow Fingers and Nails

First the tar and nicotine found in cigarettes stain the fingernails as the smoker holds the cigarette. Not only is the nail itself stained, but the smoke also stains the skin surrounding the nail bed. Second, smoking blocks oxygen to the fingernails. nicotine found in cigarette smoke cause yellow nail stains.

Oral Cancer

Smoking or using products that contain tobacco. Tobacco is carcinogenic, which means they contain chemicals that can damage the DNA in cells and lead to cancer. these are symptoms are oral cancer a lump or thickening in the oral soft tissues, soreness or a feeling that something is caught in the throat, difficulty chewing or swallowing, ear pain, difficulty moving the jaw or tongue.

Affects of Smoking on Sports Performance

Lack of Blood Oxygen and Narrowed Blood Vessels

Generally the faster your heart rate is the more oxygen your muscles needs. Cigarettes contain carbon monoxide, which binds to the hemoglobin in your blood more effectively than even oxygen, which means that your muscles are unable to get the oxygen that they require during exercise. This makes your heart work even harder. we need oxygen in are bodies to create mitochondria cells, we need oxygen to

Smoking will narrow your blood vessels, this makes blood getting pumped throughout your body a slower and more difficult process while playing sports. It also puts extra strain on your heart every time it pumps, because it has to work harder in order to supply your body with the blood oxygen it needs to function.

Increased Resting Heart Rate and Airway Resistance

Your resting heart rate is also increased by smoking, it is greatly increased in smokers because of their extra work your heart must do in order to meet all physiological demands of your body. This also means that when exercising, your heart rate could possibly rise to dangerous levels in order to meet the physical demands you're requesting of it.

Airway resistance refers to the rate at which air enters and exits your lungs. One inhalation of a cigarette can increase this resistance by up to three times. Other factors such as tar build up, inflamed mucous membranes and reduced air capacity will also increase airway resistance, making it more and more difficult to produce the oxygen your body needs when playing sports.
