Stacked red blood cells, coloured scanning electron micrograph (SEM). These stacks of red blood cells, known as ‘rouleaux’


Blood-filled foetal aorta. Coloured scanning electron micrograph (SEM) of a fracture through a foetal aorta filled with red blood cells (erythrocytes, red). The aorta is the body’s main artery. It carries blood from the heart around the body. The vessel wall consists of an inner layer of endothelial cells (tunica intima, blue, rippled) surrounded by a muscle wall (tunica media, purple), which contracts to squeeze blood along the aorta. Surrounding the aorta is connective tissue. ...

Fat cell. Coloured scanning electron micrograph (SEM) of an adipocyte (fat cell, blue). Surrounding the adipocyte are white blood cells (red).


Muscle fibre. Coloured scanning electron micrograph (SEM) of a freeze-fractured skeletal (or striated) muscle fibre. The fracturing of the fibre has revealed that it consists of a bundle of smaller fibres called myofibrils. The myofibrils are crossed by transverse tubules (horizontal lines), that mark the division of the myofibrils into contractile units (sarcomeres).
