CH # 12: Circulatory System Flashcards
WBC’s that lack granules in the cytoplasm
Agranulocytes
Substances produced by the body that inactivate or destroy other substances that r introduced in2 the body; immunoglobulins
Antibodies
2 names 4 immunity that is the result of B-cell action and the production of antibodies
Antibody-mediated immunity
Humoral immunity
Substances that trigger an immune response when they r introduced in2 the body
Antigens
Thin-walled chambers of the heart that receive blood from veins
Atria/atrium
Valves between the atria and ventricles in the heart
Atrioventricular valves
A complete heartbeat consisting of 1 contraction and relaxation of both atria and both ventricules
Cardiac cycle
Immunity that is the result of T-cell action
Cell-mediated immunity
The process of blood clotting
Coagulation
2 names 4 cardiac muscle cells specialized 4 conducting action potentials 2 the myocardium; part of the conduction system of the heart
Conduction myofibers
Purkinje fibers
The process by which WBC’s squeeze between the cells in a vessel wall 2 enter the tissue spaces found outside the blood vessel
Diapedesis
Relaxation phase of the cardiac cycle; opposite of systole
Diastole
The thin, smooth inner lining of each chamber of the heart
Endocardium
The outer layer of the heart wall; visceral pericardium
Epicardium
RBC’s
Erythrocytes
The process of RBC formation
Erythropoiesis
A hormone released by the kidneys that stimulates RBC production
Erythropoietin
2 names 4 RBC production, which occurs in the red bone marrow
Hematopoiesis
Hemopoiesis
A stem cell in the bone marrow from which RBC’s arise
Hemocytoblast
The iron-containing protein in RBC’s that is responsible 4 the transport of oxygen
Hemoglobin
The control or stopping of bleeding
Hemostasis
Substances produced by the body the inactivate or destroy other substances that r introduced in2 the body; antibodies
Immunoglobulins
WBC’s
Leukocytes
Large phagocytic connective tissue cell that functions in immune responses; name given 2 a monocyte after it leaves the blood and enters the tissues
Macrophages
