identifies the role of tissues in the formation of an organ in organ system
Answers
Explanation:
Key points. Humans—and other complex multicellular organisms—have systems of organs that work together, carrying out processes that keep us alive. The body has levels of organization that build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems.
Answer:
Tissues are groups of similar cells that have a common function. The four basic tissue types are epithelial, muscle, connective, and nervous tissue. Each tissue type has a characteristic role in the body:
Explanation: Epithelium covers the body surface and lines body cavities.
Muscle provides movement.
Connective tissue supports and protects body organs.
Nervous tissue provides a means of rapid internal communication by transmitting electrical impulses.
Organs: Made of Tissues
An organ is a structure that is composed of at least two or more tissue types and performs a specific set of functions for the body. The liver, stomach, brain, and blood are all different organs and perform different functions. Each organ is a specialized functional center responsible for a specific function of the body.
At the organ level, complex functions become possible because of the specialized activities of various tissues. Most organs contain more than one tissue type. For example, the stomach consists of smooth muscle tissue for churning movement while it is innervated, but it is also supplied by blood, which is a connective tissue.
