Cells are the basic units that make up the human body. Humans are considered multicellular organisms because they are made up of millions of different types of cells, including bone cells, intestine cells, neurons, blood cells, liver cells, and muscle cells. Each cell carries out the basic processes of nutrition, sensitivity, and reproduction by obtaining nutrients, reacting to their environment, and dividing to produce new identical cells.
