DAANCE Module 1 (2022/2023) 100% Pass

DAANCE Module 1 (2022/2023) 100% Pass Myocardium Cardiac Muscle In what order does blood flow through the heart Right atrium, tricuspid valve, right ventricle, pulmonary artery, lungs, pulmonary vein, left atrium, Mitral valve, left ventricle , aorta. Right atrium receives blood from which three sources? 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 The pressure in the arteries Systolic The pressure generated in the arteries bradycardia below 60 bmp tachycardia greater then 100 bmp SA node (Sinoatrial) 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) 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 branches into right common carotid artery Lingual artery supplies the tongue and floor of mouth facial artery 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 basic supply to the face Antecubital space anterior surface of elbow Pharynx space between the nose and trachea Nasopharynx part above the back of the soft palate oropharynx lies between soft palate and epiglottis Epiglottis 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 behind the larynx (voice box) Dead space 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 controls respiration Central Nervous System consists of brain and spinal cord. Cerebrum and Cerebellum Cerebrum- thought area Cerebellum-motor area Peripheral Nervous System Sensory nerves-recieve the message/response and motor nerves- carry out the response Autonomic Nervous System Sympathetic "fight or flight" Parasympathetic "rest and digest" P wave Atrial depolarization QRS complex Ventricular depolarization T wave Ventricular repolarization Dysrhythmias abnormal rhythms
