- Location of the Heart. The human heart is located within the thoracic cavity, medially between the lungs in the space known as the mediastinum. Figure 19.2 shows the position of the heart within the thoracic cavity.
- Shape and Size of the Heart. The shape of the heart is similar to a pinecone, rather broad at the superior surface and tapering to the apex (see Figure 19.2).
- Chambers and Circulation through the Heart. The human heart consists of four chambers: The left side and the right side each have one atrium and one ventricle.
- Membranes, Surface Features, and Layers. Our exploration of more in-depth heart structures begins by examining the membrane that surrounds the heart, the prominent surface features of the heart, and the layers that form the wall of the heart.
The heart is located within the thoracic cavity. Between the two lungs and their cavities (pleural cavities) is a central cavity called the mediastinum. The heart is located inside of the mediastinum in an inner cavity called the pericardial cavity.
