Where is your heart?

Fren,

Where is your heart man? It is snugly enclosed within the mediastinum (me'deah-sti'num), the medial cavity of the thorax, the heart extends obliquely for 12 to 14cm (about 5 inches) from the second rib to the fifth intercostal space. Is it is rests on the superior surface of the diaphragm, the heart is lies anterior to the vertebral column and posterior to the sternum.

Approximately two-thirds of its mass lies to the left of the midsternal line; the balance projects to the right. Its broad, flat base, or posterior surface, is about 9 cm wide and is directed towards the right shoulder. Its apex points inferiorly towards the left hip. So..

If you press your fingers between the fifth and sixth ribs just below your left nipple, you can easily feel the beating of your heart where the apex contacts the chest wall. hence, this site is referred to as the point of maximal intensity (PMI).

That's your heart and my heart be situated fren yeh yeh yeh.
