Question Answer
composition of bloodplasma: water, dissolved solutes. formed elements: erythrocytes, leukocytes, platelets
RBCserythrocytes, no nuclei, biconcave disc: creates high surface area & gas exchange, 120 days
WBCsleukocytes, amoeboid, grandular: neutrophils, eosinophils, basophils (12hrs-3 days). agrandular: lymphocytes, monocytes (100-300 days)
plateletsthrombocytes, megakaryocytes fragments into 2000 fragments, helps stop blood loss by clotting, 5-9 days
neutrophilsphagocytize pathogens, light purple cells, multilobed nucleus
eosinophilsphagocytize antigen-antibody complex, response to parasitic infections, pink cell, bilobed nucleus
basophilsinflammatory response, release of histamine, dark purple cell, nucleus obstructed by granules
lymphocytest cells: cell mediated immunity, b cells: antibody immunity, NK cells: kills variety of pathogens
monocytesvery large horse shoe shaped nucleus, phagocytosis, transform into macrophages outside BV
list WBCs most common to least common in bodyneutrophils, lymphocytes, monocytes, eosinophils, basophils
heart position and sizemiddle of mediastinum, apex: inferior rounded tip in left ventricle, base: orgins major blood vessels, superior surfaces of atria. size of clenched fist
right atriumhas inf and sup vena cava, coronary sinus, ridges called pectinate muscles
right ventricletricuspid valve, chordae tendinease and papillary muscles, trabeculae carneae, pulmonary semilunar valve
left atriumpulmonary veins
left ventriclebicuspid valve, chordae tendinae and papillary muscles, aortic semilunar valve, thicker myocardium
coronary arteries R: marginal branch, post interventricular branch. L: circumflex, ant interventricular artery
coronary veinsgreat cardiac vein, middle cardiac vein, small cardiac vein, coronary sinus, art cardiac vein
BV: arteriestunica interna: endothelium. tunica media: SM, elastic tissue, ratios differ according to type of artery. tunica externa
veinshas tunica interna, media and externa are thinner, larger lumen, low pressure, blood volume reservoir
name all BV in circle of willisant communicating, ant cerebral, post communicating, post cerebral, int carotid, basilar, vertebral
