- Aorta
- Major artery that starts at the left ventricle and carries oxygen-rich blood to the body.
- Arteriole
- Smallest artery, leading to a capillary.
- Artery
- Blood vessel that carries blood away from the heart.
- Atrium
- One of the two upper chambers of the heart.
- Blood pressure
- The pressure exerted during circulation of the blood against the arterial walls.
- Brachial Artery
- Major artery of the upper arm.
- Capillary
- Tiny blood vessel connecting arterioles to venules, site of gas and nutrient exchange.
- Cardiac Conduction System
- The specialized contractile in conductive tissue of the heart that generates electrical impulses and causes the heart to beat.
- Cardiovascular System
- System composed of the heart and blood vessels that brings oxygen and nutrients to and takes waste away from body cells.
- Carotid Artery
- Major artery in the neck.
- Coronary Arteries
- Network of arteries supplying the heart with blood.
- Diastolic Pressure
- Pressure exerted against the arterial walls during relaxation of the left ventricle of the heart.
- Dorsalis Pedis Artery
- Artery of the foot, palpable at the top of the foot on the great toe side.
- Femoral Artery
- Major artery of the thigh.
- Heart
- The four chambered muscular organ that receives and propels blood throughout the body.
- Hypoperfusion
- Depressed delivery of oxygen and nutrients to the cells resulting from inadequate circulation of the blood through the capillaries.
- Nitroglycerin
- Medication often prescribed for patients with a history of heart problems for the relief of chest pain.
- Perfusion
- The delivery of oxygen and nutients to the body cells and removal of waste by blood flowing through the capillaries.
- Plasma
- The serum, or fluid, component of the blood.
- Platelet
- Component of the blood essential to the formation of blood clots.
- Posterial Tibial Artery
- Artery of the calf, palpable behind the medial ankle bone.
- Pulmonary Artery
- Vessel carrying oxygen-depleted blood from the hearts right ventricle to the lungs.
- Pulmonary Vein
- Vessel carrying oxygen-rich blood from the lungs to the left artrium of the heart.
- Radial Artery
- Major artery of the forearm.
- Red Blood Cell
- Component of the blood that carries oxygen to the body's cells and carries carbon dioxide away from the body's cells.
- Shock
- Depressed delivery of oxygen and nutrients to the cells resulting from inadequate circulation of blood to the capillaries.
- Sternum
- Breast bone, located in the center of the chest.
- Systolic Pressure
- The pressure exerted against the arterial wall during contraction of the left ventricle of the heart.
- Valves
- Membranes located within the heart to prevent the backflow of blood in the system.
- Vein
- Vessels that carries blood towards the heart.
- Venae Cavae
- Two major veins that carries oxygen depleted blood back to the heart: superior vena cava from the upper body, inferior vena cava from the lower body.
- Ventricle
- One of the two lower chambers of the heart.
- Venule
- Smallest vein, leading from a capillary.
- White Blood Cells
- Component of the blood that provides part of the body's immune system.
