blood

Blood is a body fluid in the circulatory system of humans and other vertebrates that delivers necessary substances such as nutrients and oxygen to the cells of the body, and transports metabolic waste products away from those same cells.

OverviewAI-generated

Blood is a body fluid and animal product that is part of the circulatory system. It is produced by bone marrow and classified as a biogenic substance. The fluid consists of blood plasma, red blood cells, white blood cells, and platelets. It exhibits red and green colors and is characterized by blood type and blood pressure.

The study of blood is conducted within the field of hematology. It is referenced by 2,568 other encyclopedia articles and has a PubMed count of 6032762. The subject is described by sources including the Explanatory Dictionary of the Living Great Russian Language, Brockhaus and Efron Encyclopedic Dictionary, Encyclopædia Britannica 11th edition, and the Jewish Encyclopedia of Brockhaus and Efron. It is assigned the NCI Thesaurus ID C12434 and is represented by the Unicode character 🩸.

Blood is composed of blood cells suspended in plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), and contains proteins, glucose, mineral ions, and hormones. The blood cells are mainly red blood cells (erythrocytes), white blood cells (leukocytes), and (in mammals) platelets (thrombocytes). The most abundant cells are red blood cells. These contain hemoglobin, which facilitates oxygen transport by reversibly binding to it, increasing its solubility. Jawed vertebrates have an adaptive immune system, based largely on white blood cells. White blood cells help to resist infections and parasites. Platelets are important in the clotting of blood.
