artery that carries blood out of the heart in the systemic circulatory system. All other systemic arteries arise from it.
continuation of the subclavian artery extending through the axillary region and ending at the neck of the humerus
any of a vast network of tiny vessels that enable the exchange of nutrients and gases between tissues and blood
accumulation of tissue fluid that occurs when the capillary filtration/reabsorption balance is disrupted, causing swelling
pressure exerted by a fluid due to gravity, including the force of blood against vessel walls
artery whose branches provide blood primarily to pelvic viscera (organs) and the pelvic wall
difference between blood's high colloid osmotic pressure (COP), caused by proteins, and tissue COP. It opposes hydrostatic pressure, reabsorbing water into capillaries through osmosis.
resistance to blood flow that occurs in all vessels as blood moves from the heart. It is caused by friction of blood against vessel walls.
smooth muscle sphincter at the opening of each capillary that controls whether the capillary is open or closed to arriving blood
device typically used to measure blood pressure, specifically systemic arterial blood pressure at the arm's brachial artery, which is at about the same height as the heart
pressure that blood exerts against vessel walls during ventricular contraction
innermost layer of the walls of arteries and veins that contains the endothelium and comes into contact with blood in the lumen
middle and typically thickest layer of arterial and venous walls. It consists in part of smooth muscle, which carries out vessels' vasodilation and vasoconstriction
decrease in vessel diameter produced by smooth muscle contraction. It decreases blood flow.
any vessel that collects blood and returns it back to the heart after it has been distributed by capillaries
flow of blood back from the body to the heart, accomplished by a combination of pressure, gravity, and contraction of skeletal muscles
smallest type of vein, 15–100 μm in diameter. It collects blood that has just passed through capillary beds.
vessel originating from a subclavian artery, supplying blood to the brain stem, cerebellum, posterior of the brain, and upper spinal cord
