septum

wall of heart tissue separating the right and left sides

atrium

upper receiving chamber of the heart (right and left)

ventricle

aortic valve

heart valve between the left ventricle and aorta

mitral valve

heart valve between the left atrium and left ventricle; also called bicuspid valve

pulmonary valve

heart valve between the right ventricle and pulmonary artery; also called a semilunar valve due to the half-moon shape of its three cusps

lymph

clear fluid consisting of fluctuating amounts of white blood cells and a few red blood cells that accumulates in tissue and is removed by the lymphatic capillaries

lymph nodes, lymph glands

small bean-shaped masses of lymphatic tissue that filter bacteria and foreign material from the lymph; located on larger lymph vessels in the axillary, cervical, inguinal, and mediastinal areas

lymph vessels

vessels transporting lymph from body tissues to the venous system

lymph capillaries

microscopic thin-walled lymph vessels that pick up lymph, proteins, and waste from body tissues
