the heart
double layered membrane, or sac, that covers the outside of the hear
Pericardium
short tube the receives all of the purified lymph from the right side of the head, neck, right chest and arm
Right lymphatic duct
sac around the lungs
Pleura
located between the left atrium and left ventricle. Closes when the left ventricle is contracting allowing blood to flow to the aorta
Mitral valve
filter inhaled air to trap dust and other particles
Cilia
muscular wall that separates the heart into a left and right side
Septum
thin, watery fluid composed of intercellular fluid which from when plasma diffuses into tissue spaces
Lymph
bronchi divided into smaller branches
Bronchioles
receives blood from the right atrium and pumps the blood into the pulmonary artery, which carries the blood to the lungs for oxygen
Right ventricle
air is forced out of lungs and air passages
Expiration
receives oxygenated blood from the lungs
Left atrium
ability to resist an infection
Immunity
bronchi and alveoli are found in this organ. 3 in right lobe and 2 in left lobe
Lungs
located between the right atrium and right ventricle. Closes when the right ventricle contracts, allowing blood to flow to the lungs and preventing backflow
Tricuspid valve
process of breathing in air
Inspiration
receives blood from the left atrium and pumps the blood into the aorta for transport to the body cells
Left ventricle
mass of lymph tissues located in the center upper part of chest
Thymus
500 million. Gas exchange
Alveoli
located between the right ventricle and the pulmonary artery. Closes when the right ventricle has finished contracting, preventing backflow
Pulmonary valve
process of breathing
Ventilation
“cardiovascular system”. Transportation system of the body. Heart, blood vessels and blood
Circulatory system
small, open-ended lymph vessels that act like drainpipes
Lymphatic capillaries
trachea divides into two near the center of the chest, carries air between trachea and lung
Bronchi
located between the left ventricle and aorta. Closes when the left ventricle is finished contracting, allowing blood to flow into the aorta and prevent backflow
Aortic valve
process of inspiration and expiration
Respiration
