Right atrium receives blood from which three sources? - CORRECT ANSWER-1. Superior Vena Cava- above the heart 2. Inferior Vena Cava- below the heart 3. Coronary Sinus- blood from the veins of the heart muscle Diastolic - CORRECT ANSWER-The pressure in the arteries Systolic - CORRECT ANSWER-The pressure generated in the arteries bradycardia - CORRECT ANSWER-below 60 bmp tachycardia - CORRECT ANSWER-greater then 100 bmp SA node (Sinoatrial) - CORRECT ANSWER-located in the right atrium and acts as the hearts pacemaker. Rhythms that start from impulses in the SA node are called sinus rhythms. AV node (Atrioventricular) - CORRECT ANSWER-located between the atria and ventricles. Transmits electrical impulses to bundle of His. The bundle of His branches into the right and left ventricles which carry the impulse from the AV node stimulating the contraction of the ventricles. Brachiocephalic artery - CORRECT ANSWER-branches into right common carotid artery Lingual artery - CORRECT ANSWER-supplies the tongue and floor of mouth facial artery - CORRECT ANSWER-starts behind the angle of the mandible and wraps around the inferior border of the mandible and travels back up to the face supplying it with blood Maxillary artery - CORRECT ANSWER-basic supply to the face Antecubital space - CORRECT ANSWER-anterior surface of elbow Pharynx - CORRECT ANSWER-space between the nose and trachea Nasopharynx - CORRECT ANSWER-part above the back of the soft palate oropharynx - CORRECT ANSWER-lies between soft palate and epiglottis Epiglottis - CORRECT ANSWER-soft tissue valve that covers the larynx (voice box), allows air in and out of longs and prevents food or liquids to enter lungs Laryngopharynx - CORRECT ANSWER-behind the larynx (voice box) Dead space - CORRECT ANSWER-area which gases are not exchanged. extends from the pharynx to bronchioles. 150cc in average adult. Adult intakes 500 cc of air but only 350cc reaches alveoli and is available for gas exchange. Medulla Oblongata - CORRECT ANSWER-controls respiration Central Nervous System - CORRECT ANSWER-consists of brain and spinal cord. Cerebrum and Cerebellum - CORRECT ANSWER-Cerebrum- thought area Cerebellum-motor area Peripheral Nervous System - CORRECT ANSWER-Sensory nerves-recieve the message/response and motor nerves- carry out the response Autonomic Nervous System - CORRECT ANSWER-Sympathetic "fight or flight"
