@almaktab2014: Study of Human Blood Cells Human blood contains three main types of cells suspended in a liquid called plasma: 1. Red Blood Cells (RBCs) * Also called erythrocytes. * They contain hemoglobin, which gives blood its red color. * Their main function is to transport oxygen from the lungs to body tissues. * They also carry some carbon dioxide back to the lungs. * Mature human RBCs do not have a nucleus. * Shape: biconcave disc. 2. White Blood Cells (WBCs) * Also called leukocytes. * They help protect the body against infections and diseases. * Unlike RBCs, WBCs have a nucleus. * Major types include: * Neutrophils * Lymphocytes * Monocytes * Eosinophils * Basophils 3. Platelets * Also called thrombocytes. * They are small cell fragments rather than complete cells. * Their main function is to help stop bleeding by forming blood clots. #almaktabpublicschool
