Chambers, valves, vessels and circulation. circulate blood throughout the lungs and various tissues of th The heart is about the size of a closed fist, weighs about 10.5 ounces and is somewhat cone-shaped. It is covered by a sack termed the pericardium or pericardial sack. The normal heart anatomy consists of a four-chambered, hollow organ. It is divided into the left and right side by a muscular wall called the septum Anatomy and Function of the Coronary Arteries. Heart and Vascular. Coronary arteries supply blood to the heart muscle. Like all other tissues in the body, the heart muscle needs oxygen-rich blood to function. Also, oxygen-depleted blood must be carried away. The coronary arteries wrap around the outside of the heart
The Heart. The heart is located in the mediastinum, the cavity between the lungs. The heart is tilted so that its pointed end, the apex, points downward toward the left hip, while the broad end, the base, faces upward toward the right shoulder. The heart is surrounded by the pericardium, a sac characterized by the following two layers Farhood Saremi and Damián Sánchez-Quintana 12 General Anatomy of the Heart Introduction This chapter provides a general description of the heart anatomy and offers an outline of the relevant clinical information. Most images are produced using state of the art multidetector computed tomography (MDCT) scanner on living subjects or by meticulous dissection techniques on cadaveri
The coronary arteries run along the coronary sulcus of the myocardium of the heart. Their main function is to supply blood to the heart. This is a crucial function for myocardial function and subsequently homeostasis of the body. The arrangement of coronary arteries varies among people significantly The cardiac cycle is the sequence of events that occurs when the heart beats. As the heart beats, it circulates blood through pulmonary and systemic circuits of the body. There are two phases of the cardiac cycle: The diastole phase and the systole phase. In the diastole phase, heart ventricles relax and the heart fills with blood The human heart is the first functional organ to develop. It begins beating and pumping blood around day 21 or 22, a mere three weeks after fertilization. This emphasizes the critical nature of the heart in distributing blood through the vessels and the vital exchange of nutrients, oxygen, and wastes both to and from the developing baby
Appreciating the surface anatomy of the heart is helpful in determining the most appropriate site for an incision to gain access to a given cardiac chamber. 2 For example, the relatively bloodless outlet portion of the right ventricle just beneath the origin of the pulmonary trunk affords ready access to the ventricular cavity. The important landmark for the right atrium is the terminal groove.

Gross anatomy. The heart has a somewhat conical form and is enclosed by the pericardium. It is positioned posteriorly to the body of the sternum with one-third situated on the right and two-thirds on the left of the midline. Its left-sided orientation is formally known as levocardia (cf. dextrocardia ) The heart has played an important role in understanding the body since antiquity. In the fourth century B. C., the Greek philosopher Aristotle identified the heart as the most important organ of the body, the first to form according to his observations of chick embryos. It was the seat of intelligence, motion, and sensation -- a hot, dry organ heart. •Between these two layers is the pericardial cavity which contains little amount of fluid (pericardial fluid) that acts as a lubricant to facilitate movements of the heart.
