Overview of Cardiovascular System in Health and Disease Flashcards
Heart & Blood Vessels
Functions to circulate blood throughout body
Pulmonary circulation
Deoxygenated blood from RHS of heart to lungs and returns oxygenated blood to LHS of Heart
Systemic Circulation
Oxygenated blood from LHS of heart to body cells and tissues & returns deoxygenated blood to RHS of heart
Main Functions of CV system
Circulate Blood
Bring O2 and other molecules to cells and tissues
Remove waste
Regulate body temp
Components of CV System
Heart
Arteries
Arterioles
Capillaries
Venules
Veins
Arterial Disease
High BP
Clogging of arteries with atheroma plaques - block blood flow eventually
Clinical effects
Risk factors for CV Disease
Modifiable - smoking, high BP, dyslipidemia, diabetes melitus, diet, obesity, physical inactivity
alcohol, stress
Non-modifiable- family history, age, genders
Coronary Artery Disease
Hearts need blood supply from coronary arteries
Can be blocked
Damage of caridac muscle and impairment of heart function
Other Non-Ischaemic Heart Disease
Heart Valve disease
COngenital Heart Disease
Intrinsic Disease of Cardiac Muscle
Cardiac infections
Symptoms of Heart Disease
No symptoms
Sudden death
Chest pain
Shortness of breath
Swollen lower limbs
Palpitations
Dizziness
Loss of consciousness
Some diseases of CV System
Arterial disease
Venous disease
Structural abnormalities of heart
Infections
