Instead of the term "fibrous tissue", there are several antonyms that one can use to describe the tissues in a human body: soft, smooth, or pliable. Soft tissue refers to the tissues that connect, support, or surround other structures and organs of the body, such as muscle, adipose, and connective tissues. Smooth tissue, on the other hand, refers to the types of muscles that are not under voluntary control, including the smooth muscles found in the digestive system, blood vessels, and organs. Lastly, pliable tissue describes a type of tissue that is malleable and can be easily shaped, like cartilage or adipose tissue. Overall, these antonyms provide a more varied vocabulary to describe the different types of tissues present in the human body.
