2BE0HBY SEM of a gold (Au) labeled red blood cell. Red blood cells (RBCs), also called erythrocytes, are the most common type of blood cell and the vertebrate's principal means of delivering oxygen (O2) to the body tissues- via blood flow through the circulatory system. RBCs take up oxygen in the lungs and release it into tissues while squeezing through the body's capillaries. In humans, mature red blood cells are flexible and oval biconcave disks. They lack a cell nucleus and most organelles, in order to accommodate maximum space for hemoglobin; they can be viewed as sacks of hemoglobin, with a plasm

2BE0H47 This scanning electron micrograph (SEM) depicted a number of red blood cells found enmeshed in a fibrinous matrix on the luminal surface of an indwelling vascular catheter; Magnified 7766x. In this instance, the indwelling catheter was a tube that was left in place creating a patent portal directly into a blood vessel. The cell in the center was a white blood cell, also known as a leucocyte. The biconcave cytomorphologic shape of the red blood cell, or erythrocyte, increases its surface area of this hemoglobin-filled cell, thereby, promoting a greater degree of gas exchange, which is its prima

2BE0H43 #6 in a six-step sequence of the death of a cancer cell. A cancer cell has migrated through the holes of a matrix coated membrane from the top to the bottom, simulating natural migration of a invading cancer cell between, and sometimes through, the vascular endothelium. Notice the spikes or pseudopodia that are characteristic of an invading cancer cell (1). A buffy coat containing red blood cells, lymphocytes and macrophages is added to the bottom of the membrane. A group of macrophages identify the cancer cell as foreign matter and start to stick to the cancer cell, which still has its spikes

2BE0H14 SEM depicting red blood cells found enmeshed in a fibrinous matrix on the luminal surface of an indwelling vascular. The erythrocyte in the center had undergone the process of crenation, whereupon, it developed a number of cell wall projections, thereby, transforming it into what is termed an acanthocyte. Acanthocytosis could be indicative of a number of hematologic disease processes, but in this instance, was probably due to the fixation procedure carried out on this specimen prior to electron micrographic viewing. Note the normally appearing, biconcave cytomorphologic shape of the other eryt

2BE0GFT Colored scanning electron micrograph (SEM) of human red blood cells (erythrocytes). Red blood cells are biconcave, giving them a large surface area for gas exchange, and highly elastic, enabling them to pass through narrow capillary vessels. The nucleus and other organelles are lost as the cells mature. The cell's interior is packed with hemoglobin, a red iron-containing pigment that has an oxygen-carrying capacity. The main function of red blood cells is to distribute oxygen to body tissues and to carry waste carbon dioxide back to the lungs.

2BE0GCG Blood cells and platelets. Scanning electron micrograph (SEM) of human blood showing red and white cells and platelets. Red blood cells (erythrocytes) have a characteristic biconcave-disc shape and are numerous. These large cells contain hemoglobin, a red pigment by which oxygen is transported around the body. They are more numerous than white blood cells one of which is visible in this sample. White blood cells (leukocytes) are rounded cells with microvilli projections from the cell surface. Leucocytes play an important role in the immune response of the body. Platelets are smaller cells that
