Mod 2B A&P Review

Chapters 12, 13, 14, 15 Thursday 12/13 Review

QuestionAnswer
Mediastinum Space between the lungs where the heart is.
Autoimmunity Process in which a person's immune system attacks the person's own body tissues.
Stroke Volume The amount of blood that is ejected from the ventricles.
Isoimmunity Immune response to antigens of another human, as in transplanted tissues (rejection syndrome)
Pernicious Anemia Deficiency of red blood cells caused by a lack of Vitamin B12
Hypovolemic Shock Circulatory failure caused by drop in blood volume that causes blood pressure to drop (low volume shock)
Thrombus Stationary blood clot
Varicose veins Enlarged vein in which blood pools; also called varix.
Umbilical vein Large vein carrying oxygen-rich blood from the placenta to the deveoloping fetus.
Heparin Substance that prevents clots from forming
TPA Tissue Plasminogen Activator; dissolves the clot
Tricuspid valve The valve located between the right atrium and right ventricle
Blood volume Cause of blood pressure
Aneurysm Abnormal widening of the arterial wall.
Femoral Artery Located in the groin.
Dorsalis Pedis Artery Located on top of the foot.
Popliteal Artery Located behind the knee.
Carotid Artery Located in the neck
Brachial Artery Located at the elbow
Anaphylitic Shock Circulatory failure caused by a type of severe allergic reaction; cht. by blood vessel dilation.
Angina Pectoris Severe chest pain resulting when the myocardium is deprived of sufficient oxygen.
Agglutinate Antibodies causing antigens to clump or stick together.
Right Lymphatic Duct Where lymph from the right side of the head, neck and upper torso flows.
Hemoglobin Oxygen carrying protein in the blood
Universal Donor Type O
Universal Recipient Type AB
Pharyngeal Tonsils Adenoids; located in the nasopharynx.
Cisterna Chyli Enlarged pouch on the thoracic duct that serves as a storage area for lymph.
Atria Receiving chamber of the heart
Parietal pericardium Membrane surrounding the heart like a loose-fitting sack to allow the heart enough room to beat.
Endocardium Thin layer of very smooth tissue lining each chamber of the heart.
Lymphadenitis Inflammation of a lymph node, caused by a bacterial infection or tumor; cht. by swelling and tenderness.
Systemic Lupus Erythmatosis SLE; Autoimmune; Chronic inflammatory disease caused by widespread attack of self-antigens by the immune system; cht. by red rash on face.
WBC Granulocytes Neutrophils, Eosinophils, Basophils
Diastole Relaxation of the heart
Systole Contraction of the heart muscle.
Cardiac Output Volume of blood pumped by one ventricle per minute.
SA Node Sinoatrial node; Pacemaker
Thoracic Duct Largest lymphatic vessel in the body; Carries most of the lymph back to the blood (about 3/4ths)
Right Lymphatic Duct Terminal vessel into which lymphatic vessels empty lymph; the duct then empties the lymph into the circulatory system.
Leukocytosis Abornmally high white blood cell count
Arteriosclerosis Hardening of the arteries
Vitamin K Reduces risk of hemorrhage; may give before surgeries.
Cardiogenic Shock Circulatory Shock caused by heart failure.
Right ventricle forces___________ blood through the pulmonary
Septic Shock Circulatory failure resulting from complications of septicemia (toxins in blood resulting from infection)
Phagocytosis Ingestion and digestion of particles by a cell.
Phlebitis Inflammation of a vein.
Ventricles Discharging chambers of the heart.
Spleen Largest lymphatic organ; filters blood; destroys wornout RBC's, salvages iron from hemoglobin and serves as a blood resevoir.
Cerebrovascular Accident (CVA) Stroke; where blood clot travels to the brain
First heart sound Caused by abrupt closure of bicuspid and tricuspid valves.
Agranulocytes Monocytes and Lymphocytes
Active Natural Acquiring an immunity to a subsequent infection
Passive Natural Fetus receivs protection from the mother through the placenta or infant from mother's milk.
Active Artificial Vaccination
Passive Artificial Injection of antibodies that was developed by another individual's immune system to the infection person.
Gangrene Decay
Veins Carry blood toward the heart
Arteries Carry blood away from the heart
Capillaries Made up of endothelial cells and responsible for material exchange
Systemic Circulation Blood flow from the left ventricle to all parts of the body back to the right atrium.
Hepatic Portal System Unique blood route through the liver; maintains homeostasis and blood has already passed through the capillaries.
Axillary Artery Located under the arm (armpit)
Arterioles & Arteries Arteries subdivide into arterioles.
Lymphangitis Inflammation of a lymph vessel, caused by infection
Arteries carry what type of blood Blood that is not rich in oxygen
High or Low heart rate may.... Damage the body
Incompetent valves can.... Affect blood returning to the heart
Lowest pulse in the body In the feet; popliteal artery on top of foot.
Lymph nodes function Filter, destroy, create WBC, defense against bacteria
Lacteals Lymphatic capillaries in the intestinal wall for fat transportaion.
Antibodies and Antigens.... Glue together
Function of B Cells Activated B cells develop into plasma cells, plasma cells secrete antibodies into the blood.
Ductus Venosus Allows blood to bypass the immature liver.
Tunica Media Muscle layer
Tunica Externa Outer layer; heavy in veins, thin in arteries.
Tunica Intima Endothelial cell inner layer.
Foramen Ovale Shunts blood from the right atrium directly into the left atrium allowing most blood to bypass a developing baby's lungs.
Lymph Fluid formed in the tissue spaces that returns excess fluid and protein to the blood via lymphatic vessels.
Elephantiasis Extreme swelling in the limbs caused by parasitic worm infestion.
Contact dermatitis Skin inflammation due to contact with an antigen
Urticaria Hives
Aorta Largest artery in the body
Arterioles Small branch of an artery that control the flow of blood into capillaries.
Two principal categories of lymphoma Hodgkin disease and non-Hodgkin disease; both malignant
