Circ. and lymph test

Circulation and Lymph Study Guide

Aquired Immunodeficiency Syndrom AID's caused by HIV
Adenoids paired lymphoid structures in the nasopharynx
Aneurysm abnormal widening of the arterial wall
Arteries vessel carrying blood away from the heart
Arterioles small branch of an artery
Artificial Active Immunity intentional exposure to the causative agent, such as an vaccination, by individual's own immune system responds to a harmful agent
Autoimmune Condition process in which a person's immune system attacks the person's own body tissue
Blood flow through the vessels aorta-arteries(to tissues and organ)-arterioles-capillaries(out of organ cap beds by venules to veins to inf/sup vena cava)-right atruim-right ventricle-pulmonary artery-lung arterioles-capillaries-lung venules-4 pulmonary veins-left atrium-left ventricle
Capillaries tiny vessels that connect to arterioles and venules
Causes of decreased blood pressure blood loss (hemorrhage) diuretics- drugs that promote water loss by increasing urine output to treat hypertension decrease in heart output decrease in heart rate low blood viscosity relaxed muscles of blood vessel wall
Cisterna Chyli an enlarged pouch on the thoracic duct that serves as a storage area for lymph moving toward it's point of entry into the venous system
Complement Cascade rapid-fire series of chemical reactions involving proteins called complements triggered by certain antibody-agtigen reactions and resulting in the formation of tiny protein rings that create holes in a foreign cell thus cause it's destruction
Contact Dermatitis a local skin inflammation that lasts a few hours or days and is initiated by the skin being exposed to an antigen
Ductus Arteriosus connects the aorta and the pulmonary artery, allowing most blood to bypass the fetus's developing lungs
Ductus Venosus a continuation of the umbilical vein that shunts blood returning from the placenta past the fetus's developing liver directly into the inferior vena cava
Elephantiasis extreme lymphedema in the limbs caused by a parasitic worm infestation
Foramen Ovale shunts blood from the right atrium directly into the left atrium allowing most blod to bypass the baby's developing lungs
Gangrene tissue death that involves decay of tissue
Hepatic Portal Circulation the route of blood flow through the liver
Hodgkin Disease typer of lymphoma characterized by painless swelling of lymph nodes in the neck, progressing to other regions
Hypertension Risk Factors high stress levels obesity calcium deficiencies high levels of alcohol and caffine intake smoking lack of exercise
Ischemia reduced flow of blood to tissue resulting in impairment of cell function
Isoimmunity immune response to antigens of another human
Lacteals a lymphatic vessel located in each villus of the intesine, serves to absorb fat materials from the chyme passing thorugh the small intestine
Lymph node/Function performs biological filtration of lymph on its way to the circulatory system
Lymphadenitis inflammation of a lypmh node, usually caused by a bacterial infection or occasionally a neoplasm and characterized by swelling and tenderness
Lymphangitis inflammation of lypmh vessels, usually caused by a infection characterized by fine red streaks extending from the site of infection; may progress to septicemia
Natural Active Immunity exposure to the causative agent is not deliberat by individual's own immune system responds to harmful agents
Natural Passive Immunity exposure to the causative agent is not deliberate, immunity developed in an other individual or animal and transferred
Non-Hodgkin lymphoma type of lymphoma characterized by swelling of lymph nodes and progressing to other areas
Pharyngeal Tonsils adenoids, paired lymphoid structures in the nasopharynx
Phelbitis inflammation of a vein
Pulse Locations superficial temporal artery facial artery carotid artery brachial artery radial artery femoral artery popliteal (posterior to knee) [posterior tibial dorsalis pedis
Right Lymphatic Duct 25% of body drains to it lymph from the right upper extremity and from right side of the head, neck, and upper torso flow into it
Spleen largest lymphoid organ; filters blood, destorys worn-out red blood cells, salvages iron from hemoglobin, and serves as blood reservoir
Stroke results from ischemia of brain tissue caused by an embolism or ruptured aneurysm
Structure that carries oxygen rich blood form the mother to the body placenta
Structure/Veins tunic externa-connective tissue fibers(outer most layer) tunica media- smooth muscle tissue(middle layer) tunica intima- endothelial cells(inner layer)
Systemic circulation starts left ventricle
T-Lymphocytes cells that are critical to the function of the immune system, produce cell-mediated immunity
Thoracic Duct largest lymphatic vessel in the body
Thymus small lymphoid tissue organ located in the mediastinum, extending upward in the midline of the neck
Types of Shock & Possible Causes Cardigenic shock-any heart failure Hypovolemic shock-loss of blood volume in blood vessels Neurogenic shock-widespread dilation of blood vessel Anaphylatic shock-acute allergic reaction Septic shock-complications of septicemia
Urticaria an allergic or hypersensitivity response characterized by raised red lesions (hives)
Varicous Vein enlarged vein in which blood pools
Venules small blood vessels that collect blood from the capillaries and join to form veins
