Heart

Cardiology
Study of the heart and heart diseases
What is the heart?
- Hollow, cone-shaped organ
- Approximately 12cm long, 9cm wide, 6 cm thick
Where is your heart located?
Front, behind your sternum slightly to the left (middle, slightly left of your chest in between the lungs)
What is your Pleura
Covers the inside of the rib cage and spreads over the lungs
What is your diaphragm
Thin skeletal muscle that sits at the base of the chest and separates the abdomen from the chest
What is your apex?
The confluence of the inferior and left borders
What is your pericardium?
Fluid-filled sac that surrounds your heart and roots of the major blood vessels that extend from your heart
What/where is the superior vena cava
- Return deoxygenated blood from the systemic circulation to the right atrium of the heart
- To the right of your sternum, above your aortic arch
What/where is the aortic arch
- Section of the aorta between ascending and descending aorta
- Left aortic arch is the main arch
- Ends and starts at level of 2nd rib, lies within superior mediastinum
What/where is your pulmonary trunk
- Arises from the base of the right ventricle
3 heart surfaces of the anterior view
- Atrioventricular Groove (separates atria and ventricles of the heart [near the vena cava’s])
- Anterior Interventricular Groove (sternal costal surface of the heat, close to left margin of heart [on the opposite side as the vena cavas])
- Apex (@ tip of left and right ventricles, bottom of heart, 5th intercostal space, bottom tip of the heart)
