Jul 13, 2023 · Need a refresher on the basic anatomy of the heart? Check out our heart diagrams, quizzes and worksheets. Although the coronary arteries and their branches are considered as end arteries, they participate in various anastomoses (especially during intrauterine life).

Jan 25, 2025 · 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.

Jan 7, 2025 · This detailed illustration demonstrates the hierarchy of blood vessels, from major arteries and veins to microscopic capillaries, showing how blood circulates from the heart to tissues and back. The diagram uses color coding to distinguish between oxygen-rich (red) and oxygen-poor (blue) blood vessels.

Your great vessels are similar to other blood vessels in your body. The arteries carry blood away from your heart, and the veins carry blood toward your heart. However, there’s a crucial difference. Normally, arteries contain oxygen-rich blood, and veins contain oxygen-poor blood.

Nov 3, 2023 · Overview of the anatomy and functions of the heart. The heart is a muscular organ that pumps blood around the body by circulating it through the circulatory/vascular system. It is found in the middle mediastinum, wrapped in a two-layered serous sac called the pericardium.

Feb 24, 2021 · Function and anatomy of the heart made easy using labeled diagrams of cardiac structures and blood flow through the atria, ventricles, valves, aorta, pulmonary arteries veins, superior inferior vena cava, and chambers.

Dec 26, 2024 · Explore the heart anatomy with its parts, names & a clear diagram. Learn how the heart functions & its crucial role in the circulatory system

Mar 15, 2024 · In this article, we will study the heart diagram and its structure in brief. Below is a well-labelled diagram of the human heart: The diagram of heart clearly shows the human heart anatomy. The human heart consists of: Right Atrium: Receives deoxygenated blood from the body. Right Ventricle: Pumps deoxygenated blood to the lungs.

Nov 23, 2024 · This diagram illustrates the major human arteries and veins of the human body. Arterioles diverge into capillary beds. Capillary beds contain a large number (10 to 100) of capillaries that branch among the cells and tissues of the body.

Blood vessels called arteries are also shown in red, and blood vessels called veins are shown in blue. The heart is a muscular organ in the chest. It consists mainly of cardiac muscle tissue, and it pumps blood through blood vessels by repeated, rhythmic contractions.
