THE CIRCULATO RY SYSTEM EHTAR Hint: The main organ HEART ETCLVNI RES Hint: It pumps the blood VENTRICLES LTUCICRA NOI Hint: The process of transferring CIRCULATION MRTAIU Hint: The receiver ATRIUM OLBOD Hint: The body fluid BLOOD Learning Outcomes define discuss label heart, the importan the blood ce of parts of and circulator the blood y system heart vessels HOW DOES CIRCULATORY SYSTEM SIGNIFICANT IN THE HUMAN BODY. WHAT ARE THE THREE MAIN COMPONENT OF THE CIRCULATORY SYSTEM? HEART HEART The pumping organ responsible for circulating blood. BLOOD VESSELS BLOOD VESSELS The network of tubes that transport blood. BLOOD BLOOD The fluid that carries oxygen, nutrients, and waste products. The Anatomy of Heart Label the parts of the heart ATRIA It receives blood from the veins of the body and lungs. receives deoxygenated blood RIGHT from the body through inferior ATRIUM and superior vena cava. receives oxygenated blood from LEFT the lungs through pulmonary ATRIUM veins VENTRIC LES pump blood out of the heart pumps deoxygenated blood to RIGHT the lungs for oxygenation VENTRICLE through pulmonary artery. pumps oxygen-rich LEFT blood to the rest of the VENTRICLE body through aorta. VALVES It controls the flow of blood. PULMONARY ARTERY It carries oxygen-poor blood from your heart to your lungs. PULMONARY VEIN It transfers freshly oxygenated blood from the lungs to the left atrium of the heart. SUPERIOR AND INFERIOR VENA CAVA It carries oxygen-poor blood to your heart's right atrium. BLOOD THE FLUID OF LIFE RED BLOOD CELLS single drop of blood may contain around five million RBC per cubic millimeter HEMOGLOB IN an important iron and protein compound of RBC WHITE BLOOD CELLS cells of immune system it helps defend the body from invasion of pathogens which may cause diseases PLATELETS colorless cells that are smaller than RBC and WBC aid for blood clotting, the process that stops the flow of blood when a tissue gets damaged BLOOD CIRCULATION CIRCULATION CIRCULATION REFERS TO THE MOVEMENT AND FLOW OF SUBSTANCES THROUGH A SYSTEM PULMONARY CIRCULATION Pulmonary circulation is responsible for transporting deoxygenated blood from the heart to the lungs for oxygenation and then back to the heart. SYSTEMIC CIRCULATION Systemic circulation is responsible for supplying oxygenated blood to all the tissues and organs of the body and returning deoxygenated blood back to the heart.
