The human body contains more than 200 types of cells that can all be classified into four types of tissues: epithelial, connective, muscle, and nervous. Epithelial tissues act as coverings controlling the movement of materials across the surface.

Tissues are large groups of cells all doing the same job. The different kinds of tissues are classified into four groups, epithelial tissue, connective tissue, nerve tissue, and muscle tissue. Within each group are many kinds of tissue, but they are similar in the job they do.

['Periosteum – the dense, tough outer shell that contains blood vessels and nerves.', 'Compact or dense tissue – the hard, smooth layer that protects the tissue within.', 'Spongy or cancellous tissue – the porous, honeycombed material found inside most bones, which allows the bone to be strong yet lightweight.']

The 11 organ systems of the body are the integumentary, muscular, skeletal, nervous, circulatory, lymphatic, respiratory, endocrine, urinary/excretory, reproductive and digestive. Although each of your 11 organ systems has a unique function, each organ system also depends, directly or indirectly, on all the others.

The functions of epithelial cells are secretion, selective absorption, protection, transport, and sensing. Epithelial tissue can be found above the basement membrane. Connective tissue forms a framework and support structure for body tissues and organs. It is made of fibers, ground substance, and cells.

In humans, there are four basic types of tissue: epithelial, connective, muscular, and nervous tissue. There may be various sub-tissues within each of the primary tissues. Epithelial tissue covers the body surface and forms the lining for most internal cavities.

The four types of tissue in the body are epithelial, connective, muscle, and nervous. Epithelial tissue is made of layers of cells that cover the surfaces of the body that come into contact with the exterior world, line internal cavities, and form glands.

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).

Membranes are thin layers of epithelial tissue usually bound to an underlying layer of connective tissue. Membranes cover, protect, or separate other structures or tissues in the body. The four types of membranes are: 1) cutaneous membranes; 2) serous membranes; 3) mucous membranes; and 4) synovial membranes.

The skin is an organ of protection The primary function of the skin is to act as a barrier. The skin provides protection from: mechanical impacts and pressure, variations in temperature, micro-organisms, radiation and chemicals.

Major functions of connective tissue include: 1) binding and supporting, 2) protecting, 3) insulating, 4) storing reserve fuel, and 5) transporting substances within the body. Connective tissues can have various levels of vascularity.

Human body tissue makes up organs and other body parts. There are four main types of tissue: muscle, epithelial, connective and nervous. Each is made of specialized cells that are grouped together according to structure and function.
