Questions and Answers

What is the function of antibodies in the human body?

  • To produce hormones
  • To mark foreign substances for destruction (correct)
  • To fight against the body's own cells
  • To repair damaged tissues

    • Why can't someone with type A blood receive blood from someone with type AB blood?

  • Because their body will produce more antibodies
  • Because their body will attack the donated blood (correct)
  • Because the donated blood is not compatible with their blood type
  • Because their body is allergic to the donated blood

    • What would happen if someone with type O blood received blood from someone with type AB blood?

  • Their body would produce more antibodies
  • Their body would become immune to the donated blood
  • Their body would attack the donated blood (correct)
  • Their body would accept the donated blood

    • Why does the body not produce antibodies against its own cells?

    Study Notes

    Red Blood Cell Structure

    • The outer layer of a red blood cell is made up of a cell membrane, which is composed of lipids and embedded proteins and molecules.
    • The proteins and molecules embedded in the lipids have different functions, with two types being particularly important: A and B molecules.

    A and B Molecules

    • A and B molecules are not proteins, but rather glycolipids, a combination of sugar and fat groups.
    • Not all people have both A and B molecules on their red blood cells; some may have only one, or neither.

    Blood Transfusions

    • In medicine, blood transfusions are often necessary, but it's not possible to give just any blood to anyone.
    • The presence of A and B molecules on red blood cells determines the compatibility of blood transfusions.

    Immune System Response

    • The immune system uses antibodies to fight foreign substances in the body.
    • Antibodies are produced against substances that are not part of the body, and the body is careful not to make antibodies against itself.
    • People with A or B molecules on their red blood cells will produce antibodies against the corresponding molecule if it's not present on their own cells.

    Blood Types and Compatibility

    • There are four main blood types: A, B, AB, and O.
    • Each blood type has specific combinations of A and B molecules on their red blood cells:
      • A: only A molecules
      • B: only B molecules
      • AB: both A and B molecules
      • O: neither A nor B molecules
    • The compatibility of blood transfusions depends on the blood type of the donor and recipient:
      • A recipient cannot receive blood from an AB donor.
      • AB recipient can receive blood from A, B, or O donors.
      • O donor can give blood to anyone, making them the universal donor.
      • AB recipient can receive blood from anyone, making them the universal recipient.

    Importance of Blood Type

    • Knowing one's blood type is important in case of a blood transfusion, as it determines the compatibility of the blood received.
