Exempel på hur du använder BACKFLOW i en mening

• Urinary tract abnormality such as unusually large ureters, distended bladder, accumulation and backflow of urine from the bladder to the ureters and the kidneys (vesicoureteral reflux).
• The function of the valve is to allow blood to flow from the right atrium to the right ventricle during diastole, and to close to prevent backflow (regurgitation) from the right ventricle into the right atrium during right ventricular contraction (systole).
• Defects may be due to narrowing of one or more valves (stenosis), backflow of blood, through a leaky valve (regurgitation), or the presence of abnormal passages through which blood flows in or near the heart.
• Backflow means the undesirable reversal of flow of a liquid, gas, or suspended solid into the potable water supply; a backflow preventer is designed to keep this from happening.
• Sometimes called a check valve or a backflow preventer, a chemigation valve is an apparatus designed to protect water supplies from agricultural chemicals used during chemigation, the application of chemicals such as fertilizers and pesticides through irrigation water.
• The wafer style butterfly valve is designed to maintain a seal against bi-directional pressure differential to prevent any backflow in systems designed for unidirectional flow.
• This backflow created for a few days the tallest waterfall ever in the state of Louisiana, at , as the lake refilled with salty water from the Delcambre Canal and Vermilion Bay.
• In addition to the propellant turbopumps, staged combustion engines often require smaller boost pumps to prevent both preburner backflow and turbopump cavitation.
• A common misconception is that a "high loop" (routing a continuous drain line above a sink's flood level, for instance) will provide the same function as an air gap; this is not true, because the continuous connection in such a case will still allow backflow through siphoning.
• Insufficiency and regurgitation are synonymous terms that describe an inability of the valve to prevent backflow of blood as leaflets of the valve fail to join (coapt) correctly.
• Whenever a flexible hose is connected to a drinkable water supply, the spigot or tap should be fitted with an approved backflow prevention device, to prevent contaminated water from being siphoned back, in the event of a pressure drop.
• Hose connection vacuum breakers are installed on faucets and hose bibbs to prevent backflow into the water supply.
• Urine normally travels in one direction (forward, or anterograde) from the kidneys to the bladder via the ureters, with a one-way valve at the vesicoureteral (ureteral-bladder) junction preventing backflow.
• Pulmonic regurgitation: the backflow of blood from the pulmonary artery into the right ventricle, owing to insufficiency of the pulmonic semilunar valve.
• Pulmonary (or pulmonic) regurgitation (or insufficiency, incompetence) is a condition in which the pulmonary valve is incompetent and allows backflow from the pulmonary artery to the right ventricle of the heart during diastole.
• As diastole ends, the ventricles begin depolarizing and, while ventricular pressure starts to rise owing to contraction, the atrioventricular valves close in order to prevent backflow to the atria.
• Anorectal varices are collateral submucosal blood vessels dilated by backflow in the veins of the rectum.
• Label or manual at point-of-connection to shut-off pipe and all water treatment devices need backflow prevention system such as air gap or backflow preventer valve.
