- 72
- Reduce heart magnification - Diaphragm moves down farther, air-fluid levels seen & prevent engorgement of pulmonary vessels

- Why is this important?
- Hyper
Sthenic
Hypo
Asthenic - Body habitus determines shape, position and movement of internal organs

- Jugular Notch:
- Sternal Angle:
- Midway btwn Jugular Notch & Xiphoid Tip:
- Xiphoid Process: - How to find T7:
- Anteriorly
- Posteriorly
- JM = T2-T3
- SA = T4-T5
- T7
- XP = T9-T10 - Ant: 3-4 in inferior jug notch
- midway btwn jug notch & xiphoid
- Post 7-8in below C&
- inferior angle of scapula sits at T7

-Anatomy:
See Image
Anatomy:
