Answer: C. Organs can function because they are made of different types of interacting tissues.
Step-by-step explanation:
The relationship between tissues and organs is that each organ is made up of different types of tissues which each carry out a different type of job to help ensure the organ is working properly. In the case of the heart, the muscle tissue, connective and epithelial tissues, and the nervous tissues connect together to help the heartbeat and carry out its job throughout the human body. Each of these tissues breakdown different "jobs" of the heart and help it to function properly.
