Front 1

Blood functions to:

Back 1

• Transport hormones,oxygen, and nutrients to cells
• Transport carbon dioxide and other wastes from cells
• Fight infections by transporting antibodies and cells of the immune system
• Maintain blood pressure and regulate body temperature
• Keep the pH of body fluids within normal limits

Front 2

Blood functions help maintain

Back 2

homeostasis

Front 3

Blood has two main components:

Back 3

Plasma and formed elements (red blood cells, white blood cells, and platelets).

Front 4

Red blood cell production is controlled by

Back 4

The blood oxygen concentration

Front 5

When oxygen concentration decreases, the kidneys increase

Back 5

production of the hormone erythropoietin

Front 6

More red blood cells are produced by the

Back 6

Bone marrow

Front 7

Diseases involving RBC's includes

Back 7

• Anemia (not enough hemoglobin to transport oxygen)
• Hemolysis (rupturing of RBCs)
• Sickle-cell disease (malformed RBCs).

Front 8

White blood cells (leukocytes)

Back 8

are larger than red blood cells

Front 9

White blood cells

Back 9

have a nucleus and are translucent unless stained

Front 10

White blood cells are either

Back 10

Granular leukocytes or A granular leukocytes

Front 11

White blood cells are an important part of the

Back 11

Immune system (which protects the body from infection.

Front 12

White blood cells often use

Back 12

phagocytosis to ingest foreign compounds or cells called Antigens

Front 13

The Granular Leukocytes are

Back 13

• Eosinophils
• Basophils (and mast cells),
• Neutrophils

Front 14

Neutrophils are abundant and

Back 14

respond first to infections, and phagocytize pathogens

Front 15

The Agranular Leukocytes include

Back 15

Monocytes and Lymphocytes

Front 16

Monocytes are

Back 16

the largest white blood cells

• They can become macrophages that phagocytize pathogens and cellular debris

Front 17

Lymphocytes (B cells and T cells) are

Back 17

Responsible for specific immunity
