AP BIOLOGY

Detailed explanation-1: -Types of tissues. As we saw above, every organ is made up of two or more tissues, groups of similar cells that work together to perform a specific task. Humans-and other large multicellular animals-are made up of four basic tissue types: epithelial tissue, connective tissue, muscle tissue, and nervous tissue.

Detailed explanation-2: -There are 4 basic types of tissue: connective tissue, epithelial tissue, muscle tissue, and nervous tissue. Connective tissue supports other tissues and binds them together (bone, blood, and lymph tissues).

Detailed explanation-3: -An organ is a structure made up of two or more tissues that work together to carry out a specific job. Ex: Your heart, is an organ made up of muscle tissue, blood tissue, and nerve tissue.

Detailed explanation-4: -When different types of tissues are organized together to perform a complex function, it’s called an organ. The heart is an organ. It has muscle tissue, connective tissue, and nerve tissue all working together to pump blood. Organs can do more than one function and each function can be pretty complicated.
