Ultrasonography is based on the principle that sound can pass through human body tissues and is reflected by the tissue interfaces [nb 1] in the same way that light can reflect back on itself from a mirror. Tissue in the body will offer varying degrees of resistance, known as acoustic impedance, to the path of the ultrasound beam. When there is ...
A labelled diagram of the major arteries and veins of the human body. Near-infrared vein finder are medical devices used to try to increase the ability of healthcare providers to see veins . [ 1 ] They use near-infrared light reflection to create a map of the veins. [ 1 ]
Vascularity, in bodybuilding, is the condition of having many highly visible, prominent, and often extensively-ramified superficial veins. [1] The skin appears "thin"—sometimes virtually transparent—due to an extreme reduction of subcutaneous fat, allowing for maximum muscle definition. [citation needed]
Superficial veins are veins that are close to the surface of the body, as opposed to deep veins, which are far from the surface. Superficial veins are not paired with an artery, unlike the deep veins, which are typically associated with an artery of the same name. Superficial veins are important physiologically for cooling of the
The Visible Human Project is an effort to create a detailed data set of cross-sectional photographs of the human body, in order to facilitate anatomy visualization applications. It is used as a tool for the progression of medical findings, in which these findings link anatomy to its audiences. [ 1 ]
Exercise – any bodily activity that enhances or log physical fitness and overall health and wellness. It is performed for various reasons including strengthening muscles and the cardiovascular system , honing athletic skills, weight loss or maintenance, as well as for the purpose of enjoyment.
Computed tomography angiography (also called CT angiography or CTA) is a computed tomography technique used for angiography—the visualization of arteries and veins—throughout the human body. Using contrast injected into the blood vessels, images are created to look for blockages, aneurysms (dilations of walls), dissections (tearing of walls ...
Veins have less smooth muscle and connective tissue and wider internal diameters than arteries. Because of their thinner walls and wider lumens they are able to expand and hold more blood. This greater capacity gives them the term of capacitance vessels. At any time, nearly 70% of the total volume of blood in the human body is in the veins. [3]
