Hematopoietic compartments

The areas in the body where stem cells develop into blood cells, specifically myeloid and lymphoid compartments.

Myeloid stem cells

Stem cells that develop from bone marrow and give rise to red blood cells, platelets, granulocytes, and monocytes.

Lymphoid stem cells

Stem cells that develop from the lymphatic system and give rise to lymphocytes, specifically B cells and T cells.

Erythrocytes

Also known as red blood cells (RBCs), they originate in the bone marrow and are responsible for oxygen transport.

Biconcave

The shape of red blood cells, which allows flexibility to pass through blood vessels and capillaries.

Leukocytes

White blood cells responsible for immune defense, including the destruction of pathogens and removal of debris.

Diapedesis

The process by which leukocytes pass through the thin walls of capillaries to reach sites of infection.

Phagocytosis

The process where leukocytes engulf and digest foreign substances or cellular debris.

Agglutination

The clumping of red blood cells, used to identify blood types based on antigen-antibody interactions.

ABO blood group

A classification system for blood types that includes A, B, AB, and O, distinguished by specific antigens and antibodies.

Universal donors

Individuals with type O blood, whose red blood cells can be given to most people without causing transfusion reactions.

Rh antigen

An important antigen present on red blood cells classified separately from the ABO blood groups, associated with positive or negative blood types.

Rh-positive

Individuals who have red blood cells containing Rh antigens on their surface.

Rh-negative

Individuals who do not have Rh antigens on their red blood cells' surfaces.

Karl Landsteiner

The scientist who discovered the Rh antigen in 1940 during research with Rhesus monkeys.

O negative blood

The universal donor blood type that lacks A, B, and D antigens, minimizing the risk of transfusion reactions.

type A blood have

antigen A on the surface of their blood cell. they also have antibody B in their plasma.

typer B blood have

antigen B on the surface of their blood cells. they also have antibody A in their plasma

should a person with type A be given type B blood?

never

Type AB blood have

both antigens A and B on the surface on their red blood cells. They neither antibody A nor antibody B in their plasma .

Type AB have antibody A and B on thier plasma ?

no they neither
