The heart is located in the thoracic cavity medial to the lungs and posterior to the sternum. On its superior end, the base of the heart is attached to the aorta, pulmonary arteries and veins, and the vena cava. The inferior tip of the heart, known as the apex, rests just superior to the diaphragm. The base of the heart is located along the ...
The chest is the area of origin for many of the body’s systems as it houses organs such as the heart, esophagus, trachea, lungs, and thoracic diaphragm.
Your heart is in the center of your chest, near your lungs. It has four hollow chambers surrounded by muscle and other heart tissue. The chambers are separated by heart valves, which make sure that the blood keeps flowing in the right direction.
The heart is divided into four chambers: two atria and two ventricles. Blood is transported through the body via a complex network of veins and arteries. The average human heart weighs between...
Learn all about the heart, blood vessels, and composition of blood itself with our 3D models and explanations of cardiovascular system anatomy and physiology. The cardiovascular system consists of the heart, blood vessels, and the approximately 5 liters of blood that the blood vessels transport.
Rotate the 3D model to see how the heart's valves control blood flow between heart chambers and blood flow out of the heart. The heart is a hollow, muscular organ that pumps oxygenated blood throughout the body and deoxygenated blood to the lungs.
In humans, the heart is situated between the two lungs and slightly to the left of center, behind the breastbone. It rests on the diaphragm, the muscular partition between the chest and the abdominal cavity. What is the heart wall made up of? The heart consists of several layers of a tough muscular wall, the myocardium.
Welcome to the anatomy of the heart made easy! We will use labeled diagrams and pictures to learn the main cardiac structures and related vascular system. In addition to reviewing the human heart anatomy, we will also discuss the function and order in which blood flows through the heart.
Understanding its basic anatomy is crucial to understanding how it functions. This article provides a comprehensive look at the heart's structure with a detailed, labeled diagram and realistic photos, guiding you through each part and its role in the circulatory system.
Learn about the heart's anatomy, how it functions, blood flow through the heart and lungs, its location, artery appearance, and how it beats.
