Hemodynamics describes the flow behavior of blood. It deals with the physical principles of blood circulation and the factors that affect blood flow, such as blood pressure, blood volume, blood viscosity, flow resistance, and vascular architecture and elasticity. What is hemodynamics? Hemodynamics describes the flow behavior of blood. It deals with the physical principles of … Hemodynamics: Function, Role & Diseases
femoral artery, femoral artery, femoral artery Definition The femoral artery is the main vessel for supplying the lower extremity with oxygen-rich blood. It has a diameter of about 1cm in healthy persons (deviations or differences between the sexes can occur) and gives off numerous branches in its course. Course of the leg artery The femoral … Leg artery
Constriction and occlusion of the leg artery Constrictions or blockages in the area of the aorta can occur suddenly (acute) or over a longer period of time (chronic). Behind the popularly known “shop window disease” or “smoker’s leg” is a chronic narrowing or occlusion of the aorta. This vascular disease belongs to the complex of … Constriction and occlusion of the leg artery | Leg artery
Aneurysm of the leg artery An aneurysm is a pathological vasodilatation of an artery that leads to an excessive increase in the diameter of the vessel. An aneurysm can be congenital or acquired. The most important risk factor for the development of an aneurysm is arteriosclerosis. This in turn is mainly caused by overweight, high … Aneurysm of the leg artery | Leg artery
Systolic blood pressure is the peak blood pressure in the arterial portion of the systemic circulation that results from contraction of the left ventricle and continues into the aorta and through its branches into the arteries when the aortic valve is open. Peak blood pressure depends on several fixed and variable factors, including cardiac output, … Systolic Blood Pressure: Function, Tasks, Role & Diseases
The Bayliss effect maintains constant blood flow to organs such as the brain and kidneys despite everyday fluctuations in blood pressure. At elevated pressures, the effect induces vasoconstriction of vascular muscle. Disruption of the Bayliss effect results in persistent hyperemia and edema formation in the extracellular space. What is the Bayliss effect? The Bayliss effect … Bayliss Effect: Function, Tasks, Role & Diseases
General information The lungs are used for breathing (ventilation) and ensure that oxygen is absorbed and carbon dioxide is released. Anatomy of air conduction sections Arterial supply There are two types of vascular supply to the lungs (vascular supply to the lungs). Firstly, the oxygen-depleted blood from the heart reaches the lungs via the pulmonary … Vascular supply lung
The capillary is the finest human blood vessel. It is essential for supplying nutrients and oxygen to organs and is a vital part in the bloodstream. What are capillaries? The capillary is the smallest human blood vessel and participates in the so-called microcirculation. The thickness of its inner wall layer is only one cell. These … Capillaries: Structure, Function & Diseases
The medulla oblongata and pons are the circulatory centers of the brain and constantly receive information on blood pressure and gas composition. From here, actions to regulate the circulation are initiated if necessary, which is known as central circulatory regulation. In cardiovascular disease, the system is disrupted. What is central circulatory regulation? The circulatory system … Central Circulatory Regulation: Function, Role & Diseases
Central venous pressure is the blood pressure in the superior vena cava and right atrium of the heart. It is used in medicine as an indicator of blood volume. If venous pressure is too high or too low, it may indicate various heart and lung diseases, among others. What is central venous pressure? Central venous … Central Venous Pressure: Function, Role & Diseases
A central venous catheter is an external access to the venous system via a large vein. The plastic tubing used for this purpose is placed centrally in front of the right atrium of the heart. The advantage of this technique is that highly irritating as well as multiple drugs can be administered in parallel. What … Central Venous Catheter: Application & Health Benefits
In color-coded Doppler ultrasonography, a physician uses an ultrasound machine to examine the vascular structures of the body, taking advantage of the physical Doppler effect of different sound frequencies being emitted by faster- and slower-moving objects. During the examination, a transducer sends a sound into the body that is reflected back by the blood at … Color-coded Doppler Ultrasonography: Treatment, Effects & Risks
