Blood cells. Coloured scanning electron micrograph (SEM) of human red blood cells (erythrocytes, red), white blood cells (leukocytes, pink and cyan), and platelets (thrombocytes, yellow). The disc-shaped, biconcave erythrocytes transport oxygen to the...

Activated T lymphocytes and red blood cells (RBCs). Coloured scanning electron micrograph (SEM) of activated T lymphocytes and RBCs from a human blood sample. T lymphocytes, or T cells, are a type of white blood cell and components of the body's...

Activated T lymphocyte. Coloured scanning electron micrograph (SEM) of an activated T lymphocyte from a human blood sample. T lymphocytes, or T cells, are a type of white blood cell and components of the body's immune system. They mature in the...

White blood cells and a platelet. Coloured scanning electron micrograph (SEM) of white blood cells and a single platelet (blue). Platelets are fragments of white blood cells that under normal circumstances are small and biconcave in form. However, if...

Activated platelets, coloured scanning electron micrograph (SEM). Platelets are blood cell fragments that play an essential role in blood clotting and wound repair, and can also activate certain immune responses. They are formed in the red bone...

Human red blood cells and activated platelets trapped in a fibrin blood clot, coloured scanning electron micrograph (SEM). Platelets in the blood are small oval disks and are termed nonactivated platelets or thrombocytes. Platelets serve as the body's...

Human red blood cells, activated platelets, and fibrin threads, coloured scanning electron micrograph (SEM). Human red blood cells (RBCs), or erythrocytes, are involved in delivering oxygen to the body tissue. The cytoplasm of RBCs is rich in...
