Thrombose veineusevignette|Thrombose veineuse profonde de la jambe droite La thrombose veineuse ou phlébite est l'obstruction d'une veine par un caillot (thrombus). Suivant la localisation de la veine, on parle de : thrombose veineuse profonde des veines des membres inférieurs dans le cadre d'une maladie thromboembolique ; thrombose veineuse cérébrale ou thrombophlébite cérébrale au niveau des veines et sinus cérébraux ; thrombose veineuse superficielle.

ThromboseThrombosis (from Ancient Greek θρόμβωσις thrómbōsis "clotting") is the formation of a blood clot inside a blood vessel, obstructing the flow of blood through the circulatory system. When a blood vessel (a vein or an artery) is injured, the body uses platelets (thrombocytes) and fibrin to form a blood clot to prevent blood loss. Even when a blood vessel is not injured, blood clots may form in the body under certain conditions. A clot, or a piece of the clot, that breaks free and begins to travel around the body is known as an embolus.
TrachéeEn anatomie, la trachée (du grec τραχεια, « rude, raboteuse ») est un conduit constitué de tissu fibreux et cartilagineux reliant le larynx en haut aux bronches principales gauche et droite en bas. Appartenant à l'appareil respiratoire, elle permet de conduire l'air entre ces structures. La trachée est le conduit élastique fibro-cartilagineux reliant le larynx aux bronches. Elle permet, lors de la respiration, de conduire l'air depuis le larynx vers les bronches pendant l'inspiration, et inversement pendant l'expiration.
Exercise (mathematics)A mathematical exercise is a routine application of algebra or other mathematics to a stated challenge. Mathematics teachers assign mathematical exercises to develop the skills of their students. Early exercises deal with addition, subtraction, multiplication, and division of integers. Extensive courses of exercises in school extend such arithmetic to rational numbers. Various approaches to geometry have based exercises on relations of angles, segments, and triangles.
Superficial vein thrombosisSuperficial vein thrombosis (SVT) is a blood clot formed in a superficial vein, a vein near the surface of the body. Usually there is thrombophlebitis, which is an inflammatory reaction around a thrombosed vein, presenting as a painful induration (thickening of the skin) with redness. SVT itself has limited significance (in terms of direct morbidity and mortality) when compared to a deep vein thrombosis (DVT), which occurs deeper in the body at the deep venous system level.
