  • BODY FLUIDS & CIRCULATION from class 11 human physiology with ANIMATION PART-2 for NEET include:
    BLOOD GROUPS:
    ABO Blood group system-
    Blood transfusion, agglutination, AB, A, B, O (+/-) , antigen antibody reaction.
    Rh Blood group system-
    Erythroblastosis foetalis, rh factor, rhogam etc..
    In detail. The video is specially designed in animated form with hindi explanation and english animated screen. The video covers every single line of NCERT and covers over 2 questions for NEET! The video is applicable for both 11th and NEET aspirants.
    How Blood Type Is Determined And Why You Need To Know
    Blood types are determined by the presence or absence of certain antigens - substances that can trigger an immune response if they are foreign to the body. Since some antigens can trigger a patient's immune system to attack the transfused blood, safe blood transfusions depend on careful blood typing and cross-matching. Do you know what blood type is safe for you if you need a transfusion?
    There are four major blood groups determined by the presence or absence of two antigens, A and B, on the surface of red blood cells. In addition to the A and B antigens, there is a protein called the Rh factor, which can be either present (+) or absent (-), creating the 8 most common blood types (A+, A-, B+, B-, O+, O-, AB+, AB-).
    Blood Types and Transfusion:
    There are very specific ways in which blood types must be matched for a safe transfusion. The right blood transfusion can mean the difference between life and death. Use the interactive graphic below to learn more about matching blood types for transfusions.
    Also, Rh-negative blood is given to Rh-negative patients, and Rh-positive or Rh-negative blood may be given to Rh-positive patients. The rules for plasma are the reverse.
    The universal red cell donor has Type O negative blood.
    The universal plasma donor has Type AB blood.
    There are more than 600 other known antigens, the presence or absence of which creates "rare blood types." Certain blood types are unique to specific ethnic or racial groups. That’s why an African-American blood donation may be the best hope for the needs of patients with sickle cell disease, many of whom are of African descent. Learn about blood and diversity.
    What Is A Universal Blood Donor?
    Universal donors are those with an O negative blood type. Why? O negative blood can be used in transfusions for any blood type.
    Type O is routinely in short supply and in high demand by hospitals - both because it is the most common blood type and because type O negative blood is the universal blood type needed for emergency transfusions and for immune deficient infants.
    Approximately 45 percent of Caucasians are type O (positive or negative), but 51 percent of African-Americans and 57 percent of Hispanics are type O. Minority and diverse populations, therefore, play a critical role in meeting the constant need for blood.
    Types O negative and O positive are in high demand. Only 7% of the population are O negative. However, the need for O negative blood is the highest because it is used most often during emergencies. The need for O+ is high because it is the most frequently occurring blood type (37% of the population).
    The universal red cell donor has Type O negative blood. The universal plasma donor has Type AB blood. For more about plasma donation, visit the plasma donation facts.
    What Is A Rare Blood Type?
    There are more than 600 other known antigens, the presence or absence of which creates "rare blood types." Your blood type is considered rare if you lack antigens that 99% of the people are positive for. If you somehow lack an antigen that 99.99% are positive for, your blood type is extremely rare.
    How Is My Blood Type Determined?
    It’s inherited. Like eye color, blood type is passed genetically from your parents. Whether your blood group is type A, B, AB or O is based on the blood types of your mother and father.
