blood type test

Rh antigen absent = (-)

fight bacterial infections

what is hematopoiesis?

review question:

T cells and B cells belong to the agranular category of __________________.

review question: what are the three types of blood cells?

release histamine/heparin

Parasitic Infections:
5. Plasmodium
6. Trypanosoma

phagocytes fight
bacterial infection

review question:

what type of molecule is hemoglobin? What is the function of hemoglobin?

review question:

on the blood type identification card, what would cause each of the four circles to look the way they do? What do they tell you about the person who donated the blood sample?

Rh antigen present = (+)

4. Eosinophilia

2. Sickle Cell Disease

Blood is composed of plasma, red blood cells, white blood cells, and platelets. It transports essential substances and helps maintain bodily functions. Plasma makes up about 55% of blood volume, while the other components constitute the remaining 45%

review question:

a person who is type A blood is given type B blood in a transfusion by mistake. A clot forms. Explain why.

review question:

explain what determines that a person is type B+ blood type.

someWBCs contain granules
Granules
are tiny vacuoles containing enzymes used to defend against pathogens, reduce inflammation and destroy cells.
Granulocytes are part of the
innate immune system

antibody serum used to test for agglutination

watch this short video showing neutrophils looking for pathogens.

agranular leukocyteshave few or no granules.
Monocytes and lymphocytes are agranular.
B & T lymphocytes (B cells/T cells)
defend the body against specific pathogens and as such confer specific immunity.

let's look

at RBCs

let's look

at WBCs

summary

each RBC contains 270 million hemoglobin molecules...
each can carry four oxygen molecules.

blood plasma antibodies are the opposite of the blood cell antigens

human blood

blood cell antigens are recognition proteins which determine blood types

Eldon card

type A type B type AB type O

anti-A, anti-B and anti-Rh
antibodies are impregnated on the card.
Blood added to the card will clot if the blood exhibits antigens
on its cell surfaces which bind to the
antibodies on the card.

fight viral infections

immature RBCs have a nucleus.
as they mature, they enucleate.
the ejected nucleus is engulfed by macrophages. this adaptation allows red blood cells to maximize their oxygen-carrying capacity by fitting in loads of hemoglobin and increases the RBC's flexibility to get through narrow capillaries.

Rh antigen determines
blood type
(+) or (-)
