What are the four primary types of tissues in the human body?

The four primary types of tissues in the human body are epithelial, connective, muscle, and nervous tissue.

Epithelial tissue serves as a protective barrier covering body surfaces and lining cavities and organs, playing a crucial role in absorption, secretion, and sensation. Connective tissue supports, binds, and protects other tissues and organs in the body; it includes a variety of subtypes such as bone, blood, and adipose tissue. Muscle tissue is responsible for movement and is classified into three types: skeletal, cardiac, and smooth muscle. Nervous tissue is essential for transmitting electrical impulses throughout the body, allowing for communication between different body systems.

The other options contain combinations of tissue types, but they do not accurately represent the four primary classifications recognized in human biology. Adipose and bone are subtypes of connective tissue rather than standalone categories, while mentioning specific types like cartilage and skeletal without recognizing the broader classifications misses the essential framework of tissue types in the human body.
