Stroke (also known as a cerebrovascular accident (CVA) or brain attack) is a medical condition in which poor blood flow to the brain causes cell death. [5] There are two main types of stroke: ischemic, due to lack of blood flow, and; hemorrhagic, due to bleeding. [5] Both cause parts of the brain to stop functioning properly. [5]
Capillaries join the arteries and veins. The circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the entire body of a human or other vertebrate. [ 1][ 2] It includes the cardiovascular system, or vascular system, that consists of the heart and blood vessels (from Greek kardia ...
Deep vein thrombosis. Deep vein thrombosis ( DVT) is a type of venous thrombosis involving the formation of a blood clot in a deep vein, most commonly in the legs or pelvis. [ 9][ a] A minority of DVTs occur in the arms. [ 11] Symptoms can include pain, swelling, redness, and enlarged veins in the affected area, but some DVTs have no symptoms.
8.9 million (2015) [ 12] Coronary artery disease ( CAD ), also called coronary heart disease ( CHD ), ischemic heart disease ( IHD ), [ 13] myocardial ischemia, [ 14] or simply heart disease, involves the reduction of blood flow to the cardiac muscle due to build-up of atherosclerotic plaque in the arteries of the heart. [ 5][ 6][ 15] It is the ...
6947. Iron-deficiency anemia (or iron deficiency anaemia) is a common anemia that occurs when iron loss (often from intestinal bleeding or menses) occurs, and/or the dietary intake or absorption of iron is insufficient. In such a state, hemoglobin, which contains iron, cannot be formed. [ 5] Plummer–Vinson syndrome.
Infarction occurs as a result of prolonged ischemia, which is the insufficient supply of oxygen and nutrition to an area of tissue due to a disruption in blood supply.The blood vessel supplying the affected area of tissue may be blocked due to an obstruction in the vessel (e.g., an arterial embolus, thrombus, or atherosclerotic plaque), compressed by something outside of the vessel causing it ...
Cerebrovascular disease includes a variety of medical conditions that affect the blood vessels of the brain and the cerebral circulation. Arteries supplying oxygen and nutrients to the brain are often damaged or deformed in these disorders. [ 2] The most common presentation of cerebrovascular disease is an ischemic stroke or mini-stroke and ...
Vasodilation is a function within the circulatory system that occurs when the smooth muscles in the blood vessels relax, allowing the blood vessels to widen or dilate. This increases blood flow to ...
