Blood Cells:
Blood Cells like Red blood cells carry the protein hemoglobin, which attaches to oxygen and delivers it to all of the body's tissues. Red blood cells are flat and round, and very small, allowing them to easily turn corners with the flow of the blood and fit through the capillaries, the tiniest blood vessels, where oxygen is transferred to body cells.
Nerve Cells:
Nerve cells, or neurons, carry electrical messages to and from the brain and spinal cord, helping the body respond to various stimuli, regulate mechanisms, and absorb and store information. To most efficiently transmit these electrical messages, neurons have a long, thin structure, allowing for very quick and accurate communication and responses. Length is beneficial to the structure of a neuron because electrical messages within a neuron travel more quickly than the chemical messages between neurons. Thus, fewer, longer neurons means faster transmission of signals.
Muscle Cells:
Skeletal muscle cells are arranged in bundles of linear fibers. A single muscle cell is elongated in shape, containing within it many myofibrils, or thin strands made up of the proteins actin and myosin, that perform muscle contraction. The elongated shape allows the contraction proteins to line up in an overlapping pattern that makes muscle flexing possible. Nuclei and other organelles that are normally within a cell lay at the perimeter of muscle cells, making space for the ordered patterns of the proteins

Explanation:
nerve cells transport impulse from one nerve to another nerve so they have long cells
blood cells only need to transport oxygen so they don't need long cell it's enough to have circular cells
