Pick a word in each set of options to best describe relationships between interacting parts of the human body.

The human body is composed of systems with interacting parts. Organ systems are made of (organs / organelles / tissues), which are composed of specialized cells that work together to form (organs / organelles / tissues). Each cell of the human body contains (organs / organelles / tissues) with a specific function.

• organelles, organs, tissues

• tissues, organs, organelles

• organs, tissues, organelles
