Perfectly

* | Process in which the liquid in the blood, or plasma, is separated from the cells

Plasmapheresis

Bleeding disorder characterized by hemorrhage into the tissues

Purpura

Removal of the spleen

Splenectomy

Deficiency of platelets that causes an inability of the blood to clot. The most common cause of bleeding disorders.

Thrombocytopenia

The ways that the body has acquired antibodies to specific diseases (Can be active passive, natural, or artificial)

Acquired immunity

When blood cells clump together as a result of escaping their normal vessels.

Agglutination

The antibody to agglutinogen

Agglutinin

In blood, antigens are called agglutinogens because their presence can cause the blood to clump

Agglutinogen

The body produces antibodies that nullify, or neutralize, the antigens

Antibody

Substances that produce an immune reaction by their nature of being perceived as foreign to the body

Antigen

Use a process called humoral immunity (aka antibody-mediated immunity). They secrete antibodies to “poison” their enemies.

B cells

Combat parasites and release histamine and heparin which heal damaged tissue. Absorb basic dye and stain a bluish color. Type of granulocyte.

Basophil

Transports gases, chemical substances, and cells that defend the body. Regulates the body’s fluid and electrolyte balance, acid-base balance, and regulates temperature. Protects the body from infection. Protection of the body from loss of blood by the action of clotting

Blood

The process of changing a liquid to a solid

Coagulation

Chemical messengers secreted by cells of the immune system that direct immune cellular interactions

Cytokine

Cells that absorb an acidic dye, which causes them to appear reddish. Defend body against allergens and parasites. Type of granulocyte.

Eosinophil

Red Blood Cells (RBCs)

Erythrocyte

Process of blood formation

Hematopoiesis

A protein-iron pigment that helps transport O2 and CO2 throughout the body. Red blood cells carry O2 and CO2.

Hemoglobin

Control of blood flow; that is, stopping the bleeding

Hemostasis

A “steady state.” A continual balancing act of the body systems to provide an internal environment that is compatible with life

Homeostasis

* | Resistance of an organism to infectious diseases

Immunity

Antibodies

Immunoglobulins (Ig)

A type of cytokine that sends messages among leukocytes to direct productive action

Interleukin

White blood cells (WBCs)

Leukocyte

Fluid that circulates through the lymphatic system

Lymph

Also known as lymph glands, filter the debris produced by macrophages. Can become enlarged when pathogens are present.

Lymph node

Carry lymph via valves (one-way vessels)

Lymph vessel

Aka phagocytes because they specialize in phagocytosis. Combat bacteria in pyogenic infections. Consume and remove debris. Do not absorb acidic or basic die, so they are purple in color. Type of granulocyte.

Neutrophil

Liquid portion of blood

Plasma

White blood cells that have small grains within the cytoplasm and multibodied nuclei

Polymorphonucleocyte (granulocytes)

An antigen important in pregnancy. A mismatch between the fetus and the mother can cause erythroblastosis fetalis.

Rh factor

Plasma minus the clotting proteins

Serum

Organ in the lymphatic system. Located in the upper left quadrant of the abdomen and serves to filter, store and produce blood cells; remove RBCs; and activate B lymphocytes.

Spleen

All blood cells originate from a single | type of cell called a stem cell

Stem cell

Neutralize enemies through cell-mediated immunity. They attack antigens directly. They are effective against fungi, cancer cells, protozoa, and organ transplants

T cell

Also called clotting cells, cell fragments, or platelets

Thrombocyte

The thymus gland is located in the mediastinum and develops T lymphocytes (T cells)

Thymus

Lymphatic tissue that helps protect the entrance to the respiratory and digestive systems. An organ in the lymphatic system.
