What follows the cellular level in the organizational structure of the body?

After the cellular level, the next level in the organizational structure of the body is tissues. At the cellular level, individual cells perform specific functions necessary for the life of the organism. However, cells do not operate in isolation; instead, they group together to form tissues. Tissues are composed of similar cells that work together to carry out a particular function.

There are four primary types of tissues in the human body: epithelial, connective, muscle, and nervous tissue. Each tissue type has unique characteristics and functions, contributing to the overall operation of organs. From tissues, the next level of organization continues to be organs, which are structures made up of two or more types of tissues that work together to perform specific tasks within the body. This progression from cells to tissues is fundamental in understanding how complex systems are built from simpler structures in biology.
