Clinical Anatomy 2: Cardiovascular and Lymphatic System Flashcards
Location of the Heart
Mediastinum (cavity b/t the lungs)
Location of the Heart Base
2nd Left Rib
Location of the Heart Apex
Left 5th Intercostal Space
Superficial Membrane of the Heart
Pericardium
Composition of the Pericardium
- Parietal Pericardium (outer)
- Visceral/Epicardium (inner)
- Pericardial Cavity (b/t Parietal and Visceral)
Fluid in the Body that Reduces Friction
Serous
The 3 Walls of the Heart
- Epicardium (outer; serous)
- Myocardium (middle; muscle)
- Endocardium (inner: epithelial and CT)
Vessels through which the right ventricle pumps blood to the lungs
Pulmonary Trunk and Arteries
Vessels through which the left atrium receives blood from the lungs
Pulmonary Veins
Vessel through which the left ventricle pumps blood to the body
Aorta
Valve located b/t right atrium and right ventricle
Right AV / Tricuspid
Valve located b/t pulmonary trunk and right ventricle
Pulmonary Valve
Valve located b/t the left atrium and left venticle
Left AV / Bicuspid / Mitral
Valve located b/t the left ventricle and aortic trunk
Aortic Value
Vessels branching from the aorta that supply the heart with oxygenated blood
Coronary Arteries
Where coronary veins return blood to
Right Atrium
The 3 Layers of Arteries
- Tunica Intima / Endothelium (inner; simple squamous
- Tunica Media (middle, smooth muscle, elastic CT)
- Tunica Adventitia (outer; CT)
Large arteries have an abundance of _____ fibers in the tunica media and adventitia
Elastic
Tissues of capillaries
Simple Squamous
Where substances are exchanged b/t tissues and blood
Capillary Beds
Blood vessels with valves
Veins
The largest artery in the body and forms an arch over the heart
Aorta
Branch of the ascending aorta that gives rise to the right common carotid artery and right subclavian artery
Brachiocephalic / Innominate Artery
Branch of the ascending aorta that supplies the left side of the head and neck
Left Common Carotid Artery
Branch of the ascending aorta that supplies the left arm
Left Subclavian Artery
The 3 Branches of the Ascending / Aortic Arch
- Brachiocephalic / Innominate Artery
- Left Common Carotid Artery
- Left Subclavian Artery
