In biology, a type is one particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralize the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen.
A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution.
According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost always based on one particular specimen, or in some cases specimens. Types are of great significance to biologists, especially to taxonomists. Types are usually physical specimens that are kept in a museum or herbarium research collection, but failing that, an image of an individual of that taxon has sometimes been designated as a type. Describing species and appointing type specimens is part of scientific nomenclature and alpha taxonomy.
Paul Andersen explains the importance of blood types in blood transfusions. He starts with a brief discussion of blood antigens and antibodies. He describes how the ABO differs from the Rh blood type. He shows you how to solve simple genetic problems using Punnett squares. He then talks about the percentage distribution of the different types and the problems that may result during pregnancy.

These include the type 1 and type 2 pneumocytes, and the alveolar macrophages. Type 1 Pneumocyte = Squamous Alveolar Cells Type 2 Pneumocyte = Great Alveolar Cells Alveolar Macrophages = Dust Cells
Now that we've talked about your blood vessels, we're going to zoom in a little closer and talk about your blood itself. We'll start by outlining the basic components of blood -- including erythrocytes, leukocytes, platelets, and plasma -- as well as the basic process of hemostasis that stops bleeding, and how antigens are responsible for the blood type that you have. By the end of this episode, you should be totally prepared for your next blood drive.

Join Kaplan MCAT Expert Adam Grey as he shows how to relate MCAT Science to everyday life! Like a lot of people in the world of med school admissions, Adam thinks about MCAT science a lot. Seeing the world through this lens is vital to becoming a successful medical student and physician, and it helps to maximize your MCAT score as well. The "MCAT Science" web series is about seeing echoes of the MCAT in our everyday lives. Each video will be very short (no more than 2 minutes long), so the series should be a very quick-hit, low-commitment way to give yourself that extra edge on Test Day. In this video, Adam shares his thoughts about blood types as related to the MCAT. Find more MCAT test prep information at www.kaptest.com/mcat
