     • The heart is composed of smooth muscle. It has four chambers which contract in a specific order, allowing the human heart to pump blood from the body to the lungs and back again with high efficiency. The heart also contains “pacemaker” cells which fire nerve impulses at regular intervals, prompting the heart muscle to contract.

   • 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.

   Oct 31, 2024 · The heart consists of several layers of a tough muscular wall, the myocardium. A thin layer of tissue, the pericardium, covers the outside, and another layer, the endocardium, lines the inside. The heart cavity is divided down the middle into a right and a left heart, which in turn are subdivided into two chambers.

   Which side of the heart consists of a atria and a ventricle?

   • Each side of the heart consists of an atrium and a ventricle which are two connected chambers. The atria (plural of atrium) are where the blood collects when it enters the heart. The ventricles pump the blood out of the heart to the lungs or around the body. The septum separates the right-hand and left-hand side of the heart.
