| Question | Answer |
| 5 types of WBC | 1.Neutrophils 2.lymphocytes 3.monocytes 4.eosinophils 5.basophils |
| erythrocytes | red blood cells, contains hemoglobin (oxygen-carrying protein) 4.2-6.2 million RBC's per microliter of blood, life span for a RBC- 120 days |
| Leukocytes | white blood cells protects the body against infection, 5,000-10,000 WBC's per microliter Leukocytosis: ^in WBC (infection&lukemia) Leukopenia: v in WBC (viral infection&chemotherapy) |
| thrombocytes | platelets, 140,000-440,000 platelets per microliter, life span of 9 to 12 days |
| pulmonary circulation | sends deoxygenated blood from the RV to the lungs (alveoli give oxygen) sends oxygenated blood from the lungs to the LA |
| systemic circulation | sends oxygenated blood from the LV to the body |
| tricuspid valve | atrioventricular valve between the RA & RV |
| pulmonice valve | Semi lunar valve between the RV & pulmonary artery |
| mitral valve (bicuspid valve) | atrioventriculae valve between the LA &LV |
| aortic valve | semi lunar valve between the LV & Aorta |
| Layers of the Heart | 1.endocardium 2.myocardium 3.epicardium |
| endocardium | inner layer: lining of the heart |
| myocardium | muscular middle layer: contractile element of the heart |
| epicardium | outer layer of the heart, the coronary arteries is found on the heart & supplys blood to the heart |
| blood vessels | aorta, arteries, arterioles, capillaries, venules, veins, superior and inferior vena cavae |
| aorta, arteries, arterioles | carry oxygenated blood to the body |
| venules, veins, superior and inferior vena cavae | carry deoxygenated blood back to the heart |
| Circrulatory | sends oxygen, nutrients, hormones and enzymes to the cells. send waste such as carbon dioxide and urea to the organs. |
