• A sac that surrounds the heart and is filled with fluid that encloses the heart and all of he other large blood vessels that surround the heart
• Holds the heart in place while the fluid inside and is flexible so that when the heart pumps there is no friction against the other organs or bone in the body as not to cause pain
• A thick and muscular chamber where blood is dumped into by the right atrium, located in the lower right side of the heart.
• Receives blood from the right Atrium and uses the muscular walls to pump deoxygenated blood out of the heart through the right pulmonary artery which carries blood to the lungs in order to get oxygen
• A thick and muscular chamber located on the lower left side of the heart. It is the strongest chamber of the heart and receives blood from the left atrium
• Receives blood from the left atrium of the heart and uses the muscular walls to pump oxygenated blood into the aorta. It is the strongest chamber in the heart because it is used to pump blood through the aorta throughout the entire body and back to the right atrium of the heart
• A thin walled upper chamber of the heart, located above the right ventricle
• It received deoxygenated blood from the superior and inferior vena cava's and dumps it into the right ventricle of the heart
• A thin walled upper chamber in the heart, located above the left ventricle
• Receives oxygenated blood from the lungs through the pulmonary vein and dumps it into the left ventricle so that the blood can be spread throughout the body
• A large curve shaped artery, attached to the left ventricle and spreading from the left side of the heart to the rest of the body and all of its organs except for the lungs
• Blood is pumped into the aorta from the left ventricle and the muscle power from the left ventricle helps to pump the oxygenated blood through the entire body in order to give it energy and nutrients and whatever else it needs.
• An artery coming off of the aorta that supplies oxygenated blood to the muscular tissue of the heart
• Blood that does not reach it over the hump at the top of the aorta pools at the aorta valves and then drains into the coronary artery where the blood is taken to the tissues of the heart so that it has energy to pump blood throughout the body
• An muscular artery attached to the right ventricle
• Uses the muscular walls to pump deoxygenated blood from the heart to the lungs in order for the blood to collect oxygen
• A vein connecting the lungs to the left atrium of the heart. Carries oxygenated blood from the lungs to the left atrium of the heart to be stored.
superior vena cava
• A vein that receives deoxygenated blood from the upper body such as the head, arms, and chest and carries it back to the right atrium of the heart.
inferior vena cava
• A vein that receives deoxygenated blood from the lower body such as the lower limbs and abdominal cavity and carries it back and empties it into the right atrium of the heart.
• Located to the left of the stomach below the diaphragm
• Used to store blood, disintegrate old blood cells, filter foreign substances, and produce lymphocytes.
