largest artery in body; carries blood from left ventricle of heart to thorax and abdomen
blood vessel between artery and capillary, surrounded by smooth muscle; primary site of vascular resistance
thick-walled elastic vessel that carries blood away from heart to arterioles
chamber of heart that receives blood from veins and passes it on to ventricle on same side of heart
pressurized contents of the cardiovascular system composed of a liquid phase (plasma) and cellular phase (red and white blood cells, platelets)
blood vessels
tubular structures of various sizes that transport blood throughout the body
bulk flow
movement of fluids or gasses from region of higher pressure to one of lower pressure
one of the smallest blood vessels
cardiovascular system
heart and blood vessels
circulatory system
the heart and system of vessels that deliver blood to all parts of the body
red blood cells
formed elements
solid phase of blood, including cells (erythrocytes and leukocytes) and cell fragments (platelets)
muscular pump that generates blood pressure and flow in the cardiovascular system
percentage of total blood volume occupied by blood cells
the factors describing what determines the movement of blood, in particular, pressure, flow and resistance
hydrostatic pressure
pressure exerted by fluid
inferior vena cava
(VEE-nah KAY-vah)
large vein that carries blood from lower half of body to right atrium of heart
white blood cell
blood circulation in arterioles, capillaries, and venules
liquid portion of blood; component of extracellular fluid
cell fragment present in blood; plays several roles in blood clotting
pulmonary artery
large, branching vessel carrying oxygen-poor blood away from the heart toward lungs
pulmonary circulation
cirulation through lungs; portion of cardiovascular system between pulmonary trunk, as it leaves the right ventricle, and pulmonary veins, as they enter the left atrium
pulmonary trunk
large artery that carries blood from right ventricle of heart to lungs
pulmonary veins
large, converging vessels returning oxygen-rich blood toward the heart from the lungs
resistance (R)
hindrance to movement through a particular substance, tube, or opening
superior vena cava
large vein that carries blood from upper half of body to right atrium of heart
systemic circulation
circulation from left ventricle through all organs except lungs and back to heart
vascular system
closed system of blood vessels that includes all arteries, arterioles, capillaries, venules, and veins
any vessel that returns blood to heart
cavity, as in cerebral ventricle or heart ventricle; lower chamber of heart
small vessel that carries blood from capillary network to vein
measure of friction between adjacent layers of a flowing liquid; property of fluid that makes it resist flow
