    simply saying, heart’s function is to * take the blood from vena-cava(both superior and inferior) * pump it through the pulmonary artery to the lungs * after the lungs oxygenate the received blood, blood is sent to the heart through the pulmonary. The Structure of the Heart is adapted to its function in several ways: It is divided into a left side and a right side by the right ventricle pumps blood only to the lungs while the left ventricle pumps blood to all other parts of the requires much more pressure, which is thy the wall of the left ventricle is much thicker than that of the right ventricle.

Facts about the human heart. A human heart is roughly the size of a large fist. The heart weighs between about 10 to 12 ounces ( to grams) in men and 8 to 10 ounces ( to grams) in women.

The heart is the organ that helps supply blood and oxygen to all parts of the body. Heart anatomy focuses on the structure and function of the : Regina Bailey.

Although its operation may seem simple, the truth is that its beating involves the coordination of movement of the heart muscle and the correct functioning of its different parts. Its importance is such that the cessation of its functions causes our death (unless artificial mechanisms are used that perform their same function).

The Mayo Clinic Heart Book is outstanding. This book is written for everyone; it is not a medical textbook. If you remember basic high school biology, you should have no problems understanding this book.

A well labeled human heart diagram given in this article will help you to understand its parts and functions. from heart 1. Superior and inferior vena cava-veins that bring blood from the body to the heart 2.

Pulmonary artery and vein-take blood to the lungs and return it to the heart 3. Aorta: large artery that blood enters as it leaves the L ventricle of the heartFile Size: 1MB. The heart is a muscular organ in most animals, which pumps blood through the blood vessels of the circulatory system.

Blood provides the body with oxygen and nutrients, as well as assisting in the removal of metabolic wastes. In humans, the heart is located between the lungs, in the middle compartment of the chest. In humans, other mammals, and birds, the heart is divided into four chambers Nerve: Accelerans nerve, vagus nerve.

The heart pumps around litres of blood in a day throughout the body. The heart is situated at the centre of the chest and points slightly towards the left. On average, the heart beats abouttimes a day, i.e., around 3 billion beats in a lifetime.

The average male heart weights around to grams (10 to 12 ounces). Heart Disease and Congestive Heart Failure.

It consists of four chambers: the right atrium, right ventricle, left atrium, and left ventricle.

The right-sided chambers provide blood flow to the lungs, while. In order to understand how that happens, it is necessary to understand the anatomy and physiology 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.

Figure 1. The heart is a muscular organ roughly the size of a closed fist. It sits in the chest, slightly to the left of center. As the heart contracts, it pumps blood around the body. The heart is a muscular organ about the size of a fist, located just behind and slightly left of the breastbone. The heart pumps blood through the network of arteries and veins called the.
