Shunt (medical) - Citizendia

In medicine, a shunt is a hole or passage which moves, or allows movement of, fluid from one part of the body to another. Medicine is the art and science of healing It encompasses a range of Health care practices evolved to maintain and restore Human Health by the Bodily fluids listed below are found in the bodies of men and/or women Human anatomy, which with physiology and biochemistry is a complementary basic medical science is primarily the scientific study of the morphology of the adult Human body The term may describe either congenital or acquired shunts; and acquired shunts (sometimes referred to as iatrogenic shunts) may be either biological or mechanical. A congenital disorder is a disease or disorder that is present at birth An acquired disorder is a Medical condition which develops post- Fetally in contrast with a Congenital disorder, which is present at Birth The terms iatrogenesis and iatrogenic artifact refer to adverse effects or complications caused by or resulting from medical treatment or advice

Cardiac shunts may be described as right-to-left, left-to-right or bidirectional, or as systemic-to-pulmonary or pulmonary-to-systemic. Cardiac shunts may be described as right-to-left, left-to-right or bidirectional, or as systemic-to-pulmonary or pulmonary-to-systemic A right-to-left shunt is a cardiac shunt which allows or is designed to cause Blood to flow from the Right heart to the Left A left-to-right shunt is a cardiac shunt which allows or is designed to cause Blood to flow from the Left heart to the Right A bidirectional shunt is a cardiac shunt which allows or is designed to cause Blood to flow freely between the Right heart and the A systemic-to-pulmonary shunt is a cardiac shunt which allows or is designed to cause Blood to flow from the Systemic circulation A pulmonary-to-systemic shunt is a cardiac shunt which allows or is designed to cause Blood to flow from the Pulmonary circulation

Cerebral shunt: In cases of hydrocephalus, a one-way valve is used to drain excess cerebrospinal fluid from the brain and carry it to other parts of the body. In cases of Hydrocephalus (most commonly found as a birth defect a silicone elastomer tube called a shunt is used to drain excess Cerebrospinal fluid from the Brain Hydrocephalus (pronunciation ˌhaɪˌdɹoʊˈsɛfələs is a term derived from the Greek words "hydro" meaning water and "cephalus" meaning head and this condition A check valve, clack valve, non-return valve or one-way valve is a Mechanical device, a Valve, which normally allows Fluid Cerebrospinal fluid ( CSF) Liquor cerebrospinalis, is a clear Bodily fluid that occupies the Subarachnoid space and the Ventricular system The brain is the center of the Nervous system in animals All Vertebrates and the majority of Invertebrates have a brain This valve usually sits outside the skull, but beneath the skin, somewhere behind the ear. The skin is the outer covering of living tissue of an animal (or plant The ear is the sense organ that detects Sounds The Vertebrate ear shows a common biology from Fish to Humans with variations

Pulmonary shunts exist when there is normal perfusion to an alveolus, but ventilation fails to supply the perfused region. A pulmonary shunt is a physiological result when the Alveoli of the Lung is perfused with blood as normal but ventilation (the supply of air In Physiology, perfusion is the process of nutritive delivery of Arterial Blood to a Capillary bed in the Biological tissue. An alveolus (plural alveoli, from Latin alveolus, "little cavity" is an anatomical structure that has the form of a hollow cavity In Respiratory physiology, ventilation (or ventilation rate) is the rate at which gas enters or leaves the Lung.

A portosystemic shunt (PSS), also known as a liver shunt, is a bypass of the liver by the body's circulatory system. A portosystemic shunt (PSS, also known as a liver shunt, is a bypass of the Liver by the body's Circulatory system. The liver is a vital organ in the human body and is present in Vertebrates and some other animals This is an article about the rock music band "Circulatory System" It can be either a congenital or acquired condition. Congenital PSS is an uncommon condition in dogs and cats, found mainly in small dog breeds such as Miniature Schnauzers and Yorkshire Terriers, and in cats such as Persians, Himalayans, and mix breeds. The Miniature Schnauzer is a breed of small Dog of the Schnauzer type that originated in Germany in the mid-to-late 19th century The Yorkshire Terrier (or known as a Yorkie) is a breed of small Dog in the The Persian (Persia گربه ایرانی) is one of the oldest breeds of Cat. The Himalayan, also called colorpoint Persian and colloquially referred to as Himmy, is a breed of Cat with extremely long fluffy fur and the blue Acquired PSS is also uncommon and is found in older dogs with liver disease causing portal hypertension, especially cirrhosis. In Medicine, portal hypertension is Hypertension (high blood pressure in the Portal vein and its branches Cirrhosis is a consequence of chronic Liver Disease characterized by replacement of liver tissue by fibrous Scar tissue as well as regenerative

A portacaval shunt/ portal caval shunt is a treatment for high blood pressure in the liver. A portacaval shunt (or portal caval shunt) is a treatment for High blood pressure in the liver
