• oxygen
  • Blood is a body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells. (wikipedia.org)
  • These contain hemoglobin, an iron-containing protein, which facilitates oxygen transport by reversibly binding to this respiratory gas and greatly increasing its solubility in blood. (wikipedia.org)
  • In most insects, this "blood" does not contain oxygen-carrying molecules such as hemoglobin because their bodies are small enough for their tracheal system to suffice for supplying oxygen. (wikipedia.org)
  • Right tube: Freshly drawn blood One microliter of blood contains: 4.7 to 6.1 million (male), 4.2 to 5.4 million (female) erythrocytes: Red blood cells contain the blood's hemoglobin and distribute oxygen. (wikipedia.org)
  • potassium
  • If you have any problems with your kidneys your kidney function and the amount of potassium in your blood should be regularly monitored while you are taking this medicine. (netdoctor.co.uk)
  • ischemia
  • A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by loss of blood flow (ischemia) in the brain, spinal cord, or retina, without tissue death (infarction). (wikipedia.org)
  • An arterial embolism is caused by one or more emboli getting stuck in an artery and blocking blood flow, causing ischemia, possibly resulting in infarction with tissue death (necrosis). (wikipedia.org)
  • Watershed strokes are caused by ischemia or a lack of blood flow to the brain. (wikipedia.org)
  • levels
  • Low levels of the protein albumin in the blood (hypoalbuminaemia). (netdoctor.co.uk)
  • People with high blood pressure caused by high levels of the hormone aldosterone (primary hyperaldosteronism) do not generally respond to this type of blood pressure lowering medicine, and it is not recommended for these people. (netdoctor.co.uk)
  • The pancreas also is responsible for producing insulin and glucagon , two hormones that help control levels of blood sugar, the body's main energy source. (kidshealth.org)
  • If a doctor suspects pancreatitis, the first step is to perform blood tests, like an amylase test or lipase test , to see whether the enzymes made by the pancreas are at normal working levels. (kidshealth.org)
  • HLPIIa is a rare genetic disorder characterized by increased levels of LDL cholesterol in the blood due to the lack of uptake (no Apo B receptors) of LDL particles. (wikipedia.org)
  • arterial
  • Risk factors for thromboembolism, the major cause of arterial embolism, include disturbed blood flow (such as in atrial fibrillation and mitral stenosis), injury or damage to an artery wall, and hypercoagulability (such as increased platelet count). (wikipedia.org)
  • vessel
  • A CT scan and MRI are used for diagnosis, and afterward several treatment options are available, including the removal of atherosclerotic plaque and a physical widening of the clogged blood vessel. (wikipedia.org)
  • Foam cells are formed when circulating monocyte-derived cells are recruited to the atherosclerotic lesion site or fat deposits in the blood vessel walls. (wikipedia.org)
  • The red blood cells (together with endothelial vessel cells and other cells) are also marked by glycoproteins that define the different blood types. (wikipedia.org)
  • body's
  • The combined surface area of all red blood cells of the human body would be roughly 2,000 times as great as the body's exterior surface. (wikipedia.org)
  • mainly
  • The blood cells are mainly red blood cells (also called RBCs or erythrocytes), white blood cells (also called WBCs or leukocytes) and platelets (also called thrombocytes). (wikipedia.org)
  • arteries
  • The relaxing and widening of the small arteries in the body decreases the resistance that the heart has to push against in order to pump the blood around the body. (netdoctor.co.uk)
  • In a medical context, the term "watershed" refers to those areas of the brain that receive dual blood supply from the branching ends of two large arteries. (wikipedia.org)
  • intestine
  • All people taking this medicine should stop treatment and consult their doctor immediately if they experience any sign of bleeding from the stomach or intestine during treatment, for example vomiting blood and/or passing black/tarry/bloodstained stools. (netdoctor.co.uk)
  • Short- and medium chain fatty acids are absorbed directly into the blood via intestine capillaries and travel through the portal vein. (wikipedia.org)
  • embolus
  • Symptoms may begin quickly or slowly depending on the size of the embolus and how much it blocks the blood flow. (wikipedia.org)
  • symptoms
  • Short-term symptoms can include dehydration and low blood pressure. (kidshealth.org)
  • In addition to evaluating the symptoms above, the health care provider may find decreased or no blood pressure in the arm or leg. (wikipedia.org)
  • liver
  • You should have regular blood tests to monitor your liver function (liver function tests) while taking this medicine. (netdoctor.co.uk)
  • factors
  • Despite the speed and accuracy of cell counting devices in the analysis of blood samples, several confounding factors may influence their outcomes. (ac.ir)
  • plasma
  • In vertebrates, it is composed of blood cells suspended in blood plasma. (wikipedia.org)
  • Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), and contains dissipated proteins, glucose, mineral ions, hormones, carbon dioxide (plasma being the main medium for excretory product transportation), and blood cells themselves. (wikipedia.org)
  • The average adult has a blood volume of roughly 5 litres (11 US pt), which is composed of plasma and several kinds of cells. (wikipedia.org)
  • Whole blood (plasma and cells) exhibits non-Newtonian fluid dynamics. (wikipedia.org)
  • Human blood fractioned by centrifugation: Plasma (upper, yellow layer), buffy coat (middle, thin white layer) and erythrocyte layer (bottom, red layer) can be seen. (wikipedia.org)
  • About 55% of blood is blood plasma, a fluid that is the blood's liquid medium, which by itself is straw-yellow in color. (wikipedia.org)
  • fluid
  • Insects and some mollusks use a fluid called hemolymph instead of blood, the difference being that hemolymph is not contained in a closed circulatory system. (wikipedia.org)
  • form
  • In terms of anatomy and histology, blood is considered a specialized form of connective tissue, given its origin in the bones and the presence of potential molecular fibers in the form of fibrinogen. (wikipedia.org)
  • level
  • Your doctor may need to check for side effects on the muscles by taking a blood test to measure the level of a compound called creatinine kinase in your blood. (netdoctor.co.uk)
  • several
  • There are several conditions that can predispose someone to watershed stroke by increasing the likelihood that insufficient blood supply will be able to reach the brain. (wikipedia.org)
