Karten in diesem Stapel (22)
- 1HeartA hollow muscular organ that pumps a circulation of blood through the body by means of rhythmic contraction.
- 2MediastinumThe space in the chest between the lungs that contains all the internal organs of the chest except the lungs.
- 3Sinoatrial (SA) NodeA specialized area of the cardia tissue, located in the right atrium of the heart, which initiates the electrical impulses that determine the heart rate; often termed the pacemaker for the heart.
- 4Atrioventricular (AV) NodeA small mass of specialized cardiac muscle fibers, located in the wall of the right atrium of the heart, that receives heartbeat impulses from the sinoatrial node and directs them to the walls of the ventricles.
- 5AtriumThe superior chamber of the heart that receives blood from the veins and forces it into the ventricles.
- 6VentricleThe inferior chamber of the heart that receives blood from its corresponding atrium and, in turn, forces blood into the arteries.
- 7Stroke VolumeThe amount of blood pumped out of the heart with each contraction.
- 8Heart Rate (HR)The rate at which the heart pumps.
- 9Cardiac Output (Q)Heart rate x stroke volume, the overall performance of the heart.
- 10BloodFluid that circulates in the heart, arteries, capillaries, and veins, carries nutrients and oxygen to all parts of the body, and also rids the body of waste products.
- 11Blood VesselsNetwork of hollow tubes that circulates blood throughout the body.
- 12ArteriesVessels that transports blood away from the heart.
- 13CapillariesThe smallest blood vessels, and the site of exchange of chemicals and water between the blood and the tissues.
- 14VeinsVessels that transport blood from the capillaries toward the heart.
- 15ArteriolesSmall terminal branches of an artery, which end in capillaries.
- 16VenulesThe very small veins that connect capillaries to the larger veins.
- 17Respiratory SystemA system of organs (the lungs and respiratory passageways) that collects oxygen from the external environment and transports it to the bloodstream.
- 18Respiratory PumpIs composed of skeletal structures (bones) and soft tissues (muscles) that work together to allow proper respiratory mechanics to occur and help pump blood back to the heart during inspiration.
- 19InspirationThe process of actively contracting the inspiratory muscles to move air into the body.
- 20ExpirationThe process of actively or passively relaxing the inspiratory muscles to move air out of the body.
- 21DiffusionThe process of getting oxygen from the environment to the tissues of the body.
- 22Maximal Oxygen Consumption (VO2max)The highest rate of oxygen transport utilization achieved at maximal physical exertion.
