covering of the heart, helps pump blood ng maayos, a thin walled structure na parang supot

most superficial layer of the pericardium

hold the heart in place, also protects it from infections, lubrication and has two parts

two parts of serous pericardium

outermost layer of the wall of the heart

middle, nagkakaroon ng contraction ang heart

inner layer of the wall of the heart, prevents blood clotting and ensures smooth flow

looks like meaty ridges, rounded columns, helps heart to have good ventricles and will project from the inner surface ng heart from right to left

presence of cell shape

aka myocardium, striated, intercalated disks, contraction is also possible due to calcium ions and atp

most important proteins found in our muscles

major veins found in the heart, carries deoxygenated blood from the upper body to the heart

largest artery in the body, responsible for transporting oxygenated blood from the heart to the rest of the body, maintain and regulates blood pressure and responsible also for the supply of oxygen

carry oxygenated blood from the lungs to the heart

carries deoxygenated blood from the heart to the left lung

carry oxygenated blood

carrying deoxygenated blood from the heart to the lungs

first chamber to receive oxygenpoor blood from the body, and ipa-pump to the right ventricle

receive oxygen rich blood from the lungs and pumps it to the left ventricle papuntang aorta

also known as the receiving chamber

also known as the pumping chamber

pumps oxygen poor blood to the lungs

main chamber of the heart, makapal and pinakamuscle ng heart

upper portion and holding chambers

small, thin walled, contract minimally to push blood into ventricles

lower portion and pumping chambers, thick, strong walled, contract forcefully to propel blood out of heart
