| Question | Answer |
|---|---|
| Pleura | Connective tissue around lungs |
| Visceral Pleura | Serous membrane that surrounds the lungs & connects directly to the lungs |
| Parietal Pleura | Serous membrane that surrounds the outside of the lungs |
| SA node | pace maker for the heart, located in the upper left of Right Atria |
| AV Node | second pacemaker of the heart, Located near Tricuspid valve |
| Coronary Artery | Artery that feeds heart muscle |
| Coronary artery located off the... | Ascending Aorta |
| All Deo2 blood goes to the... | Right Atria |
| 3 vessels that feed the R. Atria | Superior/Inferior Vena Cava & Coronary Sinus |
| Pulmonary Vein | Carries blood from lungs to L. Atria |
| Superior Vena Cava | Recieves blood from all veins above the diaphragm |
| Inferior Vena Cava | Recieves blood from below diaphragm |
| Myocardium | responsible for contracting and relaxing the heart |
| Endocardium | Lines inside of heart |
| Bronchial Artery | Supplies lung tissue with blood |
| 3 parts of Sternum | Xiphoid, Body, Menubrium |
| Not in Mediastimun | Lungs |
| False/Floating | 11th & 12th Ribs |
| Nerve below 12th rib | Subcostal |
| Veins from breast drain into... | Axillary area |
| Intercostals | Nerves between ribs |
| Vagus #10 | Main Parasympathetic nerve |
| Phrenic Nerve | innervates diaphragm |
| Vein system that drains blood from thoracic region into Superior Vena Cava | Azygos |
| Brachiocephalic Vein | Makes up superior Vena Cava |
| Bicuspid Valve | resembles bishops headress |
| Aortic Semi-lunar Valve | Beteween Left Ventricle and Aorta |
| Pulmonary Semi-lunar Valve | between R. Ventricle and Pulmonary Trunk |
| Serous Fluid | fluid between Visceral and Parietal pericardium |
| EKG | Traces electrical stimulation thru heart |
| Arteries off of thoracic aorta | esophegeal, mediatsinal, Intercostal, Bronchial |
| Conduction System of heart | SA node, AV node, AV bundle, Bundle Branches, perkinje fibers |
| Thymus Gland | Specializes leukocytes into T-lymphocytes |
| Systole | Contract |
| Diastole | Relax |
| Mediastinum | Central compartment containing everything in thoracic cavity except the lungs |
| Left lobe of lungs | Smaller because of cardiac notch, 2 lobes |
| right lobe of lungs | 3 lobes |
| Hemothorax | Blood in pleura |
| Pneumothorax | air in pleural cavity |
