Blood Of Plasma And Formed Elements

Blood consists of plasma and formed elements. Erythrocytes transport mainly oxygen to all body tissues. Leukocytes protect the body against pathogens by direct attack or by forming antibodies. Platelets play an important role in blood clot formation. The heart is divided into four chambers. It acts as a double pump system. The pulmonary circuit, which provides for gas exchange, is served by the right atrium and right ventricle of the heart. The systematic circuit, which supplies blood to all body tissues, is served by the left atrium and left ventricle of the heart. For each heartbeat, the P wave indicates the atrial depolarization, the QRS complex reflects the ventricular depolarization, and the T wave reflects the

Lab 4: blood consists of two major components: plasma, which is 90% water and nonliving fluid matrix, and formed elements, which are living cells suspended in the plasma. Erythrocytes, Leukocytes, and platelets are the three types of the formed elements. Erythrocytes, or red blood cells, contains hemoglobin molecules and plays an important role in oxygen (and small amount of carbon dioxide) transportation. Leukocytes, or white blood cells, helps defending the body and are part of the immune system; there are five types of Leukocytes: neutrophils, eosinophils, basophils, lymphocytes, and monocytes. Each type has a unique function in defending the body against any pathogens. Neutrophils are the most abundant, monocytes are the largest, lymphocytes are the smallest, and basophils are the least abundant leukocytes. Platelets play an important role in blood clot formation. The heart consists of four chambers: right atrium, right ventricle, left atrium, and left ventricle. The heart acts as a double pump. The pulmonary circuit is served by the right atrium and ventricle, they pump the deoxygenated blood, coming from all body tissues through the superior vena cava and inferior vena cava, to the lungs to unload carbon dioxide and upload oxygen, and then enter the left atrium of the heart. The main function of the pulmonary circulation is to allow for gas exchange. The systematic circulation carries the oxygenated blood from the left side of the heart and pump
