Flashcards in Blood Cells Deck (12):
1

Circulating Blood

Consists of Formed elements suspended within blood plasma

2

Formed Elements

Red blood cells, types of white blood cells and platelets

3

Red Blood Cells

RBCs or Erythrocytes
Small circular biconcave disc
Enclosed cytoplasm devoid of a nucleus
Contains hemoglobin
Produced in red bone marrow,
Life span of 120 days

4

Hemoglobin

Molecule responsible for transporting oxygen and some carbon dioxide to and from the tissues

5

Granulocytes

Cells containing granules
Basophils
Eosinophils
Neutrophils
All 3 based on color

6

Basophilis

Blue- Loving
Bilobed nucleus that contains an large amount of granules
Release histamine and heparin (Anticoagulant)
Limited phagocytosis of foreign matter

7

Eosinophils

Red loving
Bi-lobed nucleus
bright red granules
Responsible for allergic reactions, limited phagocytosis and response to parasites

8

Neutrophils

Pale/ neutral granules
multi-lobed (3 to 5)
First line of defense against bacterial infections and inflammatory reactions
Efficient in phagocytosis
Most numerous of white blood cells

9

Agranulocytes (Nongranulocytes)

Non granulated cells
Monocytes
Lymphocytes

10

Monocytes

Large rounded nucleus
Circulate in the blood, penetrate the connective tissues and transformed into phagocytic macrophages

11

Lymphocytes (Small and Large)

Concerned with Humoral Immunity
Production of antibodies
Small = Older
Large = Younger

12

Platelets

Do not include a nucleus
Are released pieces of megakaryocytes found in red bone marrow cavities
Blood clot formation
