CIRCULATORY SYSTEM
The circulatory system in the human beings is made up of the fluid connective tissue called blood , the vessels and
the heart. Blood consists of a fluid medium called plasma in which the cells are suspended.There is a pumping organ to push blood around the body, a network of tubes to reach blood to all the tissues and a
system in place to ensure that this network can be repaired if damaged. PARTS OF THE CIRCULATORY SYSTEM / THE CARDIOVASCULAR SYSTEM1) THE HEART

Slide 1
THE HUMAN HEART
The size of the heart is the of a clenched fist and it is located between the lungs in the thoracic cavity. A two layered sac called PERICARDIUMencloses the heart. It is made up of MYOCARDIUMi.e. cardiac muscles which is seen to contract and relax rhythmically throughout life. The heart is located towards the left side of our thoracic cavity.The heart has 4 prominent chambers.
The upper two chambers are called the Atria or the AuriclesThe lower two chambers are called the ventricles
The oxygenated and deoxygenated blood are kept separate in the left and right side of the heart respectively. The walls of the auricles are thinner than that of the ventricles as they send blood only to the ventricles, situated below them. The walls of the ventricles are thicker as theysend blood to the different parts of the body.Slide 2
THE HUMAN HEART
The wall of the left ventricle is thickest as it sends blood to all the body parts through the aorta.
The left auricle and ventricle has the bicuspid/mitral valve. The right auricle and ventricle has the tricuspid valve. The 4 chambers are separated by the septum(dividing wall). The right auricle gets deoxygenated blood via the vena cavas. The left auricle receives oxygenated blood via the pulmonary veins.The right ventricle sends out deoxygenated blood via the pulmonary arteries to the lungs. This has the pulmonary valve.
The left ventricle sends out oxygenated blood via the aorta to the body parts. This has the aortic valve.
