Answer:
Blood cells are a lot smaller than nerve cells and have a disc-shaped structure, both great traits for moving quickly through small spaces. Their disc shape also provides them with a big surface where lots of oxygen can enter the cell.

Answer:
See Below
Explanation:
Nerve cells:
They have a long fiber (axon) so they can carry messages up and down the body over long distances.
The axon is insulated by a fatty (myelin) sheath, the fatty sheath increases the speed of the nerve impulses along the neuron.
Branching at ends of the cell to connect with other nerve cells.
Red Blood Cells:
They contain haemoglobin, a red protein that combines with oxygen.
No nucleus to save space for more of this protein.
They are small and flexible so they can fit through narrow blood vessels
Biconcave shape, provides a large surface area.
Thin cell membrane to let things diffuse in and out easily.
Cells differ by shape and size for their specialized purposes.
In other words, cells have different shapes because they do different things. Each cell type has its own role to play in helping our bodies to work properly, and their shapes and sizes help them carry out these roles effectively.
Size (seen in both nerve cell is long red blood cell small)
Shape (red blood cell biconcaved nerve cell again slender and long with branching)
