Causes of asthma
Airborne allergens, (dust, etc)
Respiratory infections, such as the common cold.
Physical activity.
Cold air.
Air pollutants and irritants, such as smoke.
Causes of emphysema
Long term exposure to irritating particle in the air taken into the lungs
Causes of obesity
Physical inactivity, Overeating, Genetics, A diet high in simple carbohydrates, Diseases such as: hypothyroidism, insulin resistance, polycystic ovary syndrome, and Cushing's syndrome
Causes of heart attack
One or more of your coronary arteries becomes blocked. Over time, a build-up of fatty deposits, including cholesterol, form substances called plaques, which can narrow the arteries (atherosclerosis).
Causes of stroke
A blocked artery (ischemic stroke) or leaking or bursting of a blood vessel (hemorrhagic stroke)
mechanics of asthma
Airway narrowing occurs in asthma due to the contraction of airways smooth muscle
mechanics of emphysema
An imbalance between protease and antiprotease activity in the lungs
mechanics of obesity
Obesity causes mechanical compression of the diaphragm, lungs, and chest cavity, which can lead to restrictive pulmonary damage. Furthermore, excess fat decreases total respiratory system compliance, increases pulmonary resistance, and reduces respiratory muscle strength.
mechanics of heart attack
A heart attack occurs when an artery supplying your heart with blood and oxygen becomes blocked. Fatty deposits build up over time, forming plaques in your heart’s arteries. If a plaque ruptures, a blood clot can form and block your arteries, causing a heart attack.
mechanics of stroke
A stroke occurs when there is an interruption of the blood supply to a particular area of the brain, ultimately leading to cell injury and cell death.
