| this is the most abundant type of blood cell | red blood cell |
| these are biconcave cells that deliver oxygen to tissues, are very numerous | red blood cells |
| these cell fragments do not have a nucleus and help to form blood clots (small purple crescents between RBCs) | platelets (thrombocytes) |
| these cells are separated into granulocytes and agranulocytes | white blood cells |
| these white blood cells contain many dark staining granules in the cytoplasm and the nucleus typically takes on a multi-lobed appearance | granulocytes |
| these white blood cells contain very few dark staining granules in the cytoplasm | agranulocytes |
| these 3 white blood cell types are granulocytes | neutrophils, eosinophils, basophils |
| these 2 white blood cell types are agranulocytes | lymphocytes, monocytes |
| this white blood cell releases chemicals that change blood pressure. look for dense staining of granules in cytoplasm that obscure nucleus. | basophil |
| this white blood cell responds to the site of an acute injury or infection and performs phagocytosis of debris. look for a nucleus of 3-4 dark staining lobes with many dark staining granules in the cytoplasm. | neutrophil |
| this white blood cell responds to allergens and chronic inflammation. they release chemicals that change blood pressure. look for nuclei with two lobes and many dark staining granules in the cytoplasm. | eosinophil |

| how many atria and ventricles do frogs have compared to humans | frogs have 2 atria and 1 ventricle humans have 2 atria and 2 ventricles |
| is there oxygen separation in the frog heart | no |
| where are the pacemaker cells in a frog compared to human | frog - SV node human - SA node |
| a decrease in temperature results in this change in heart rate. this is because proteins and enzymes require higher temperatures to work efficiently. | decrease in heart rate |
| an increase in calcium concentrations leads to these changes in force and HR. the reasoning is that calcium facilitates the cross bridge formation between thick and thin filaments which increases contractility. | increase in force, little or no increase in HR |
| an increase is potassium concentration leads to this change in HR and force. this is because potassium depolarizes the membrane potential of pacemaker cells and decreases driving force. | increase in HR then decrease in HR no change in force |
| when adding isuprel to the frog heart, this is how HR and contractile force changed. This is because it activates beta1 adrenergic receptors which causes Gs stimulation, increases adenyl cyclase, increase cAMP, increase HCN channel activity, increase pKa, increase calcium concentration. | increase HR increase contractile force |
| when adding Ach to a frog heart, this happens to HR. This is because Ach activates muscarinic receptors and causes Gi stimulation which decreases adenyl cyclase, cAMP, HCN channel activity, decrease pKa, decrease calcium concentration. | decrease HR |
| When adding atropine then Ach to the frog heart, this is what happens to HR and force. This is because atropine is a plant alkaloid that blocks muscarinic receptors. | normal HR normal force |
| When mechanically stretching the frog heart, this is the expected observation. This is because of the frank-starling law | increase contractile force no decline phase due to pericardium |
| absolute refractory in a frog heart causes this channel to inactivate | Na |
| in frog heart experiment, which peak represents atrial contraction and ventricular contraction (big peak of little peak) | atrial contraction - little peak ventricular contraction - big peak |
