Blood sugar level
Blood sugar level (blood glucose concentration): glucose amount in blood, normally below 100 mg/dL fasting and 140 mg/dL post-meal; regulated by insulin and glucagon; measured via lab tests, meters, and CGM; abnormal levels define diabetes, hyperglycemia, and hypoglycemia.
Blood sugar regulation
Blood sugar regulation: hormonal control of blood glucose by pancreatic insulin (lowering) and glucagon (raising), plus incretins, counterregulation, A1C and CGM monitoring, and diabetes treatment.
Blood Sugar Sex Magik
Blood Sugar Sex Magik is the fifth studio album by Red Hot Chili Peppers (Warner Bros., September 24, 1991), also called BSSM. Produced by Rick Rubin at his Laurel Canyon Mansion, it yielded Give It Away and Under the Bridge, reached number three on the Billboard 200, and went 7x Platinum in the US.
Blood Syndicate
Blood Syndicate is a DC Comics series about a Milestone team of super-powered former gang members protecting Paris Island in the fictional city of Dakota, launched in 1993.
Blood test
A blood test, also called blood work or blood analysis, is a laboratory test measuring cells, chemicals, and proteins in blood, often part of a regular checkup.
Blood Ties (2013 film)
Blood Ties (2013) is Guillaume Canet's English-language debut, a Brooklyn-set 1970s crime drama remaking Jacques Maillot's Les Liens du sang, starring Clive Owen, Billy Crudup, Marion Cotillard, and James Caan; premiered out of competition at Cannes 2013.
Blood transfusion
Blood transfusion: intravenous infusion of donor blood or components (red cells, platelets, plasma) to treat anemia or blood loss. Safe since Landsteiner's 1901 ABO discovery; modern practice favors restrictive 7 g/dL thresholds.
Blood transfusion = Trasfusione del sangue
Blood transfusion = Trasfusione del sangue (Trasfusione del sangue) is SIMTI's bimonthly peer-reviewed transfusion medicine journal, ISSN 1723-2007/2385-2070, published in Milan, indexed in MEDLINE, Impact Factor 2.7 (2025), official journal of SIMTI and SETS.
Blood type
Blood type: classification of blood by ABO group (A, B, AB, O) and RhD status, discovered by Karl Landsteiner in 1901; determines transfusion compatibility, with O negative the universal red cell donor and 49 ISBT-recognized systems by 2026.
Blood type personality theory
Blood type personality theory (血液型性格関連説, ketsueki-gata) is the pseudoscientific Japanese belief that ABO blood type predicts personality. Proposed by Takeji Furukawa in 1927, discredited in 1933, revived by Masahiko Nomi's 1971 book; large surveys show no blood type-personality link.
Blood typing and crossmatching
Blood typing and crossmatching are the laboratory procedures that establish a patient's ABO and Rh blood group, screen for antibodies, and confirm donor blood compatibility before transfusion.
Blood Urea Nitrogen
Blood urea nitrogen (BUN) is a blood test measuring urea nitrogen, a waste product of protein breakdown, used chiefly to check kidney function; normal values run about 6 to 20 mg/dL.
Blood vessel
Blood vessels are the arteries, veins, and capillaries that carry blood through the body in pulmonary and systemic circuits; about 60,000 miles total, with three-layered walls, venous valves, and roughly 70 percent of blood volume held in veins.
Blood Vessel Prosthesis
Blood vessel prosthesis (vascular graft): artificial conduit, mainly Dacron polyester or ePTFE, implanted to bypass or replace diseased arteries; pioneered by Voorhees in 1952, successful for large vessels, still limited below 6 mm by thrombosis and intimal hyperplasia.
Blood Vessel Prosthesis Implantation
Blood vessel prosthesis implantation is the surgical placement of a synthetic vascular graft, usually Dacron or ePTFE, to replace a diseased vessel or bypass a blockage.
Blood Viscosity
Blood viscosity, the internal resistance of whole blood to flow, is non-Newtonian and shear-thinning, governed by hematocrit, plasma fibrinogen, and red cell aggregation and deformability; it marks cardiovascular, hematological, and inflammatory risk.
Blood volume
Blood volume, also called volemia, is the total amount of blood circulating in the arteries, capillaries, veins, and heart, about 5 liters in an average adult, varying with body size.
Blood Volume Determination
Blood Volume Determination: indicator-dilution measurement of circulating blood volume using 51Cr-labeled red cells and radioiodinated albumin; also called blood volume analysis, expressed in L/kg.
Blood vs Duty
Blood vs Duty is a 2026 ABS-CBN action-drama teleserye about agents fighting illegal gun smuggling, starring Richard Gutierrez, Gerald Anderson, Bela Padilla, Barbie Imperial, and Baron Geisler; 80 episodes aired from April 6 to July 24, 2026 on Kapamilya Channel, Netflix, and iWant.

Blood-oxygen-level-dependent imaging
Blood-oxygen-level-dependent (BOLD) imaging is a functional MRI technique that maps brain activity indirectly through blood oxygenation changes, first demonstrated by Seiji Ogawa at Bell Laboratories in 1990.
