Circ. and lymph test
Circulation and Lymph Study Guide
| Question | Answer |
|---|---|
| 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 |
