The largest artery of the body is the aorta, which begins at the heart.Īs they move further from the heart, arteries branch off and become increasingly smaller. This layer predominantly provides structure and support.Īrteries come in a variety of sizes. The outermost layer that’s made up of elastic fibers and collagen. The middle, and often the thickest layer, that’s made up of smooth muscle cells and elastic fibers that can help control the diameter of the blood vessel. The innermost layer that’s made up of cells called endothelial cells as well as elastic fibers. The walls of arteries are three distinct layers: contain more smooth muscle tissue and less elastic fibers.are further from the heart where blood pressure is lower.

contain more elastic fibers, which allows them to both expand and contract with the surges of blood that occur when the heart beats.are closer to the heart where blood pressure is highest.In the pulmonary circuit, oxygen-depleted blood is carried away from the heart and into the lungs where it can acquire fresh oxygen and get rid of carbon dioxide.Īrteries can also be divided into elastic and muscular arteries based off of the material of their tunica media or middle layer. In this pathway, oxygen-rich blood is carried away from the heart and toward tissues of the body. 3dBody is a scientifically accurate and artistically perfect 3D rendering of the human body.Arteries carry blood away from the heart in two distinct pathways: With just a click of a mouse, the object is immediately displayed.Įvery structure can be rotated, hidden, zoomed and made transparent. The 3dBody is a portable software program that uses little space and saves the current human anatomy image in all kinds of sizes for further study, explanation, printing, and so on.ģdBody has a fully navigable and user-friendly 3D environment that allows the user to cruise among the rich details of the human body. The human body’s systems available to view are the cardiovascular (circulatory), digestive, endocrine, lymphatic, nervous, sensory (ear and eye), urinary/reproductive, respiratory, integumentary, skeletal and musculature systems. The positioning is based on CTs, MRIs, real time dissections and authentic text books. 3dBody is a 3D interactive digital anatomy software program that reconstructs the human body 3-dimensionally so it is easy to peruse the complex details and relations of its parts.Įach and every structure in the human body is digitally sculpted and deployed in its true anatomical position.
