Terms in this set (66)
Characteristics of Elastic -largest arteries by diameter
arteries(Conducting -contain more elastic fibers than smooth muscle -
arteries) conduct blood from the heart to the more distant
muscular arteries -pressure reservoirs
Muscular -Distribute blood to various parts of the body -Contain
arteries(distributing large amounts of smooth muscle, most named
arteries) arteries in the body fall into this category
Characteristics of -smallest arteries by diameter
Arterioles -deliver blood to the capillaries, where gas and nutrient
exchange can occur
-Control amount of blood to various organs
-smallest veins
-collect blood from the capillaries
Characteristics of Venules -contain venous valves which prevent the backward flow of
blood
-attached to capillary bed
, Characteristics of Veins -contain valves
-Carry blood back to heart
-hold the most blood(blood reservoirs)
-rely on the following to return blood to the heart:
vasoconstriction, valves, skeletal muscle pump, respiratory
pump, and cardiac suction
-thinner tunica interna and media; thicker externa
lymphatic system -Immunity
functions -Lymph formation
-Fluid balance
-Transport lipids
List the organs of the Lymphatic organs - Non-moving structures that work to
lymphatic system house lymphatic tissue Primary:
-Red bone marrow
-Thymus
Secondary:
-Lymph nodes
-Tonsils
-Spleen
Describe Red bone -involved in hematopoiesis (blood formation) and immunity
marrow -Soft, loosely organized, highly vascular material
-B-cell maturation
Describe the Lymph -most numerous lymphatic organs
nodes -removes unwanted waste
-acts as a site of B-cells and T-cells activation
-found in pharynx
-helps to trap inhaled or ingested foreign substances
Describe the Tonsils -Pharyngeal tonsils
-Palatine tonsils
-Lingual tonsils
