ASU BIO 202 Lab: Blood Components and Blood Typing

Plasma

Fluid portion of blood; 55% of your blood. contains water, protein, nutrients, and ions

Formed Elements

red blood cells, white blood cells, platelets are collectively known as this; 45% of blood volume

Erythrocytes

- aka red blood cells

- carry oxygen on hemoglobin

- 44% of blood volume, most numerous blood cell

- lack nuclei and most organelles

Hematocrit

term for the percentage of red blood cells in the blood

Thrombocytes

- aka platelets

- blood clotting cells

- are not cells, but small cellular fragments

- lack nuclei and most organelles

- > 1% of blood volume

Leukocytes

- aka white blood cells

- immune system support

- less than 1% of blood volume

Granulocytes

A group of leukocytes containing granules in their cytoplasm; neutrophils, eosinophils, basophils.

Agranulocytes

A group of leukocytes without granules in their nuclei; lymphocytes, monocytes.

Neutrophil

- a type of white blood cell (granulocyte) that kills bacteria

- multilobed nuclei

- u-shaped nucleus in band cells aka immature neutrophils

Eosinophil

- a type of white blood cell (granulocyte) that kills parasitic worms

- bilobed nuclei

Basophil

- a type of white blood cell (granulocyte) involve in allergic response

- bilobed nuclei

Lymphocyte

a white blood cells (agranulocyte) that fights viruses and tumors

B lymphocytes

produce antibodies that bind to antigens

T lymphocyte

enhance other aspects of the immune response, destroy cancer cells, and destroy cells infected with viruses

Monocyte

- a white blood cell (agranulocyte) that becomes macrophages

- horse-shoe shaped nuclei

Type A

- A antigens

- Anti-B antibodies

Type B

- B antigens

- Anti-A antibodies

Type AB

- A and B Antigens

- no antibodies

- universal recipient

Type O

- No antigens

- Anti-A and Anti-B antibodies

- Universal Donor

Rh Positive

- Rh antigens

- no Anti-Rh antibodies

- can accept positive or negative blood

Rh Negative

- absence of Rh antigens

- Anti-Rh antibodies

- Can only accept negative blood
