Cardiovascular and Lymphatic 10 Flashcards
cardiac cycle
one complete heartbeat that includes contraction (systole) and relaxation (diastole) of both atria (upper heart chambers) and both ventricles (lower heart chambers)
cardiovascular system
composed of the heart and blood vessels that deliver oxygen and nutrients to the body cells and carry away cellular wastes
heart
hollow muscular organ that receives blood from the veins and propels blood through the arteries
apex
the lower pointed end of the heart formed by the left ventricle
coronary circulation
blood supply to the heart tissue
septum
wall of heart tissue separating the right and left sides
atrium
upper receiving chamber of the heart; right and left atria
ventricle
lower pumping chamber of the heart; right and left ventricle
endocardium
inner lining of the heart
myocardium
middle muscular layer of the heart
epicardium
outer lining of the heart
pericardium
sac around the heart that facilitates movement of the heart as it beats
aortic valve
heart valve between the left ventricle and aorta (main artery of the heart)
mitral valve
heart valve between the left atrium and left ventricle; bicuspid valve
pulmonary valve
heart valve between the right ventricle and the pulmonary artery; semilunar valve
tricuspid valve
heart valve between the right atrium and right ventricle
blood vessels
tubular structures that transport blood
capillary
microscopic thin-walled vessel connecting arterioles and venules where gas, nutrient, and waste exchange take place between the blood and cells of the body
lumen
interior space of a vessel
aorta
largest artery that begins as an arch from the left ventricle then branches and descends through the thoracic and abdominal cavities; carries oxygenated blood away from the heart
artery
blood vessel that carries blood away from the heart
arteriole
small artery that connects an artery to a capillary
inferior vena cava
large vein carrying blood to the heart from the lower part of the body
superior vena cava
large vein carrying blood to the heart from the upper part of the body
venule
small vein that connects a capillary to a vein
vein
vessel carrying blood to the heart
lymph
clear fluid consisting of fluctuating amounts of white blood cells and a few red blood cells; bathes tissues and is removed by the lymph 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 cervical, mediastinal, axillary, and inguinal regions
lymphatic vessels
vessels transporting lymph from the body tissues to the venous system
lymph capillaries
microscopic thin-walled lymph that pick up lymph, proteins, and waste from body tissues
lymph ducts
the largest lymphatic vessels that transport lymph to the venous system; right lymphatic duct and thoracic duct
