Function of cardiovascular system
Transport blood throughout body
Pump other substances along with blood
Facilitates delivery of vital materials to cells and picks of cellular waste
Parallel circulation (lymphatic system)
Major components of circulatory system
How is blood characterized
Connective tissue
Functions of blood
Blood Type A
Blood Type B
Effect of interaction between antibodies and foreign blood type
Agglutination resulting in serious harm and even death
Blood Type AB
Blood Type O
Components of blood
Plasma (composition, function, proteins)
Albumin
Maintains pressure to keep water in the bloodstream
Where are plasma proteins produced?
Liver
Erythrocytes (RBCs) (structure, function, proteins)
Hemoglobin
Production of erythrocytes (RBCs) (controlled by, produced in, length of maturation, lifespan)
RBC regulation: kidneys
RBC regulation: diet
RBC destruction
Leukocytes (WBCs) (function, subdivisions)
Neutrophils (subdivision + function)
Eosinophils (subdivision + function)
Basophils (subdivision + function)
T Cells (subdivision + function)
B Cells (subdivision + function)
Monocytes (subdivision + function)
Platelets (characteristic, function)
Platelets: steps
Vascular spasm
Platelet plug formation
Coagulation (clotting)
Process of blood clotting
When inner wall of vessel is damaged, underlying collagen fiber becomes exposed
Platelets floating in blood begin to attach to rough/damaged site
Attached platelets release chemicals to attract more platelets, creating platelet plug
Effect of prothrombin on blood clotting
Heart structure (# chambers, right v. left)
Layers of heart wall
Endocardium
Thin internal layer of heart also covering valves
Myocardium
Thick middle layer (cardiac muscle)
Epicardium
Thin external layer of heart
Fibrous skeleton
Right atrium
Right ventricle
Valve control
Left atrium
Left ventricle
Skeletal muscles (structural elements, function, location)
Cardiac muscles (structural elements, function, location)
Smooth muscles (structural elements, function, location)
Cardiac control (actors)
SA (sinoatrial) node
Sympathetic + parasympathetic effects on SA node
AV node
AV bundle (bundle of His)
Purkinje Fibers
Complete pathway of cardiac control
Cardiac cycle (definition, divisions)
Systole
Diastole
Both atria and ventricles undergo systole/diastole, but what do discussions of heart movement normally refer to?
Ventricular activity
