The anatomy and physiology of the heart. 61 anatomy and physiology of the heart 611 location of the heart the heart is located in the chest between the lungs behind the sternum and above the diaphragm. It is pumped into the right ventricle and then to the lungs where carbon dioxide is released and oxygen is absorbed. Without any neural stimulation the sinoatrial node rhythmically initiates impulses 70 to 80 times per minute.

Anatomy and physiology of the heart diagram of the heart blood circulation anatomy of the heart muscle anatomy anatomy coloring book heart diseases what is h. The wall of the heart consists of three layers of tissue. Myocardium the muscles of the heart.

Location of the heart the human heart is located within the thoracic cavity medially between the lungs in the space known as the mediastinum. Clinical anatomy for dummies. In order to understand how that happens it is necessary to understand the anatomy and physiology of the heart.

Basic anatomy of the heart. Its size is about that of a fist and its weight is about 250 300 g. The deep cardiac plexus is located on the bifurcation of the trachea and the superficial cardiac plexus is located on the base of the heart below the arch of the aorta.

The oxygenated blood then travels back to the left side of the heart into the left atria then into the left ventricle from where it is pumped into the aorta and arterial circulation. The conduction system includes several components. Endocardium lines the inside of the heart and protects the valves and chambers.

The first part of the conduction system is the sinoatrial node. It is surrounded by the pericardium. Its center is located about 15 cm to the left of the midsagittal plane.

Because it establishes the basic rhythm of the heartbeat it is called the pacemaker of the heart. Physiology of the heart.
