The study of the human heart and its various functions is known as cardiology.
Our heart is made up of four chambers, the left atrium, right atrium, left ventricle and right ventricle.
Blood that leaves the heart is carried through arteries to various body parts. This is oxygen rich blood. The main artery leaving the left ventricle is known as aorta while the main artery leaving the right ventricle is known as the pulmonary artery.
Blood going towards the heart is carried through veins. This blood is oxygen-poor but full of carbon-dioxide.
