Cardiovascular disease:
- Coronary Heart disease
- Narrowing: Coronary arteries that supply blood &oxygen to heart.
- Usually: from the build up of LDL cholestrol in walls of arteries
- Usually: from the build up of LDL cholestrol in walls of arteries
- Symptoms: Angina, shortness of breath, myocardial infarction.
- Loss of elasticity of arteries involved
- Narrowing: Coronary arteries that supply blood &oxygen to heart.
- Myocardial Infarction
- Areas of myocardium (heart muscle) die due to an interruption of blood flow
- Usually: from a blockage from atherosclerosis
- Symptoms: Angina, shortness of breath
- Areas of myocardium (heart muscle) die due to an interruption of blood flow
- Atheroma (Atherosclerosis)
- Plaque causes obstruction (atheromatous plaque)
- Combination of cholestrol, triglycerides & blood components
- -> Atheroma formation -> Fat deposits become invaded by fibrous tissue & then calcified
- -> Atheroma formation -> Fat deposits become invaded by fibrous tissue & then calcified
- Combination of cholestrol, triglycerides & blood components
- Symptoms: Angina, shortness of breath
- Plaque causes obstruction (atheromatous plaque)
- Aneurysm (Aortic)
- Dilation of a portion of the aorta, usually at site of weakness in the aortic wall.
- Can rupture -> dissecting aneurysm & can cause blood loss, circulatory shock, rapid death.
- Increased risk: Smoking, inheritence
- Dilation of a portion of the aorta, usually at site of weakness in the aortic wall.
- Asthma
- Allergens: -->
- Lining of airways -> inflamed
- Epethelial cells secrete more mucus
- Fluid leaves capillaries & enters airway
- Constriction of bronchi
- Lining of airways -> inflamed
- Symptoms:
- Breathing difficulty
- Wheezing (when breathing)
- Tight feeling in chest
- Coughing (reflex response to the obstructed bronchi & bronchioles - effort to clear them)
- Breathing difficulty
- Allergens: -->
- Emphysema
- Smoking: causes alveoli in lungs to collapse & reduce SA & elastacity in the lungs
- Symptoms:
- Shortness of breath
- Chronic cough
- Oxygen deficiency = blue skin
- Tight chest
- Shortness of breath
- Smoking: causes alveoli in lungs to collapse & reduce SA & elastacity in the lungs
- Fibrosis
- Scars form on the epithelium & thicken
- Gas diffusion = Harder
- Oxygen's unable to diffuse
- Lung elasticity = reduced
- Lung elasticity = reduced
- Oxygen's unable to diffuse
- Gas diffusion = Harder
- Symptoms:
- Shortness of breath (lungs fill up with fibrous tissue)
- Chronic cough (breathing difficulty)
- Chronic cough (breathing difficulty)
- Pain & discomfort
- Weakness & fatigue
- Shortness of breath (lungs fill up with fibrous tissue)
- Scars form on the epithelium & thicken
- Tuberculosis
- Inhalation of droplets to the upper region of lungs:
- Bacteria grows & divides
- White blood cells form at the infection site
- Innflamation of lymphoctus
- Bacteria's able to sit dorment
- Bacteria's able to sit dorment
- Innflamation of lymphoctus
- White blood cells form at the infection site
- Bacteria grows & divides
- Symptoms:
- Persistent cough
- Coughing blood & fever
- Loss of appetite
- Fatigue
- Persistent cough
- Treatment:
- Vaccination, medication, improving housing, health facilities, nutrition -> strong immune system
- Vaccination, medication, improving housing, health facilities, nutrition -> strong immune system
- Inhalation of droplets to the upper region of lungs:
