Humans are multicellular, complex organisms. The cells inside our bodies are “specialized.” This means that each type of cell performs a unique and special function. For this reason, each of the 200 different types of cells in the body has a different structure, size, shape, and function, and contains different organelles.

For example:

Cells in the brain may be longer in shape so they can transmit signals more efficiently.

Cells of the heart have more mitochondria because they need a lot of energy.

Cells in the respiratory system are responsible for taking up oxygen and releasing carbon dioxide.

All the cells work together to keep the human body running efficiently.
