How are tissue structures related to their function?

How are tissue structures related to their function?

Tissue is a group of cells that have similar structure and that function together as a unit. Muscle tissue is composed of cells that have the special ability to shorten or contract in order to produce movement of body parts. Nervous tissue is responsible for coordinating and controlling many body activities.

What tissues is the human body composed of?

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). Epithelial tissue provides a covering (skin, the linings of the various passages inside the body).

Which tissue supports the structure of the whole body?

Supportive connective tissue—bone and cartilage—provide structure and strength to the body and protect soft tissues.

What is the structure and function of organs?

An organ is an anatomically distinct structure of the body composed of two or more tissue types. Each organ performs one or more specific physiological functions. An organ system is a group of organs that work together to perform major functions or meet physiological needs of the body.

What are the structural components of the body?

It is convenient to consider the structures of the body in terms of fundamental levels of organization that increase in complexity: subatomic particles, atoms, molecules, organelles, cells, tissues, organs, organ systems, organisms and biosphere (Figure 1).

What is the function of tissue in the human body?

Epithelial tissues act as coverings, controlling the movement of materials across their surface. Connective tissue binds the various parts of the body together, providing support and protection. Muscle tissue allows the body to move and nervous tissues functions in communication.

What is the purpose of tissues in the human body?

Tissue is a group of cells or fluid that work together to perform a specific job in the body like cells in an organ like the kidney or heart or blood cells that carry oxygen to and waste materials from the cells in the body.

What are the structures composed of specialized tissues and performing specific functions?

Organs and Body Systems Organs are structures composed of specialized tissues designed to perform specific functions in plants and animals (Table 7-1). Body systems, also known as systems, are groups of body organs acting together to perform one or more functions.

How is the structure of a tissue different from an organ?

A tissue is a group of many similar cells (though sometimes composed of a few related types) that work together to perform a specific function. An organ is an anatomically distinct structure of the body composed of two or more tissue types. Each organ performs one or more specific physiological functions.

How are cells and organs related in the human body?

In humans, as in all organisms, cells perform all functions of life. A tissue is a group of many similar cells (though sometimes composed of a few related types) that work together to perform a specific function. An organ is an anatomically distinct structure of the body composed of two or more tissue types.

What is the function of connective tissue in the body?

1 Epithelial tissue creates protective boundaries and is involved in the diffusion of ions and molecules. 2 Connective tissue underlies and supports other tissue types. 3 Muscle tissue contracts to initiate movement in the body. 4 Nervous tissue transmits and integrates information through the central and peripheral nervous systems.

What kind of tissue is found in the human body?

Epithelial tissue covers and protects our bodies and the lining of some organs in the form of skin. Connective tissue, which can be found filling the spaces in our body, holds our parts together and provides support.
