Heart

Things to remember

• The heart is an important organ in our body. It is made up of cardiac muscles. The heart pumps blood from the heart to the different part of the body.
• The heart supplies oxygenated blood to the cells through blood vessels.
• The heart also helps to collect deoxygenated blood from different cells, send it to lungs for purification and then transport again to the cells.
• The heart has four chambers, they are Left ventricle, Right ventricle, Right auricle and Left auricle.
• The heart is a strong muscular organ. It is situated between two lungs in the thorax. It is enclosed in a membrane called pericardium. 
• The heart is internally divided into the right chamber and left chamber by a thick muscular wall called septum.
• These capillaries carry oxygenated blood and dissolved salts and sugar to the cells.
• The deoxygenated blood collected from a different part of the body reaches the right auricle of the heart via superior and inferior venacava.
