Anatomy And Physiology Of The Heart

The major blood vessels of the heart consist of large arteries and veins that transport blood to and from the different circulatory systems of the body. 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.

19 3 Cardiac Cycle Anatomy And Physiology

In order to understand how that happens it is necessary to understand the anatomy and physiology of the heart.

Anatomy and physiology of the heart. It is a four chamber pump with the right side receiving deoxygenated blood from the body at low presure and pumping it to the lungs the pulmonary circulation. It is pumped into the right ventricle and then to the lungs where carbon dioxide is released and oxygen is absorbed. Size location and orientation the heart is around the size of a fist and weighs between 250 350 grams less than a pound.

Epicardium protective layer mostly made of connective tissue. Myocardium the muscles of the heart. Physiology of the heart as the heart beats or contracts the blood makes continuous round trips into and out of the heart through the rest of the body and then back to the heart only to be sent out again.

The heart is the pump responsible for maintaining adequate circulation of oxygenated blood around the vascular network of the body. The cardiac veins run along the surface of the heart carrying deoxygenated blood to the right atrium after flowing through the myocardium. Basic anatomy of the heart.

Endocardium lines the inside of the heart and protects the valves and chambers. Enclosed within the mediastinum the medial cavity of the thorax the heart extends obliquely from the second rib to the fifth intercostal space. Location of the heart the human heart is located within the thoracic cavity medially between the lungs in the space known as the mediastinum.

The wall of the heart consists of three layers of tissue. It rests on the superior surface of the diaphragm lies posterior to the sternum and anterior to the vertebral column. Cardiovascular system anatomy physiology.

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.
