What’s cardiovascular system
Closed system that circulate blood throughout the body
3 major function of cardiovascular system
Transportation of materials
-blood
- remove wastes/co²
-hormones
Protect from pathogens
-wbc (fight pathogens)
-platelets (clotting blood)
Regulation of the body’s homeostasis
-blood vessels ( maintain body temperature)
What’s the structure of heart
Cone shape, size of a fost
Explain about heart
Anterior to the vertebral column and slightly left to midline (mediastinum)
Three distinct layers
Muscular pumping organ
What’s the function of heart
Generate blood pressure
Routing blood
Ensuring one way blood flow
Regulate blood supply
What’s 3 layers of the heart explain
Endocardium-
Inner surface
Form valve that separate atrium and ventricle
Myocardium-
Thickest layer
Interlocking layers of cardiac muscle
Epicardium -
External surface, thin layer
What’s pericardium?
Serous membrane that lining the pericardial cavity
Two types; visceral and parietal
What’s coronary circulation
Blood flow within heart
What’s pulmonary circulation
Blood flow between heart- lungs
What’s systemic circulation
Blood flow between heart- cells
Explain about systemic circulation
Superior inferior vena kava- right atrium- tricuspid valve - right ventricle - pulmonary semilunar valves - pulmonary artery - lungs- pulmonary veins- left atrium- bicuspid valve/mitral valve- left ventricle - aortic semilunar valves - aorta- systemic circulation
