What are the 4 types of tissue in the human body? What are their functions?
connective epithelial muscular nervous Epithelial tissue covers the body surface and forms the lining for most internal cavities. The major function of epithelial tissue includes protection, secretion, absorption, and filtration. The skin is an organ made up of epithelial tissue which protects the body from dirt, dust, bacteria and other microbes that may be harmful. Cells of the epithelial tissue have different shapes as shown on the student's worksheet. Cells can be thin, flat to cubic to elongated. Connective tissue is the most abundant and the most widely distributed of the tissues. Connective tissues perform a variety of functions including support and protection. The following tissues are found in the human body, ordinary loose connective tissue, fat tissue, dense fibrous tissue, cartilage, bone, blood, and lymph, which are all considered connective tissue. There are three types of muscle tissue: skeletal, smooth, and cardiac. Skeletal muscle is a voluntary type of muscle tissue that is used in the contraction of skeletal parts. Smooth muscle is found in the walls of internal organs and blood vessels. It is an involuntary type. The cardiac muscle is found only in the walls of the heart and is involuntary in nature. Nerve tissue is composed of specialized cells which not only receive stimuli but also conduct impulses to and from all parts of the body. Nerve cells or neurons are long and string-like. In tissues the simplest combination is called a membrane, or a sheet of tissues which cover or line the body surface or divide organs into parts. Examples include the mucous membrane which lines body cavities. Tissues combine to form organs. An organ is a part of the body which performs a definite function. The final units of organization in the body are called systems. A system is a group of organs each of which contributes its share to the function of the body as a whole.
How many types of tissues are there in the human body?
A tissue is a group of cells that have a similar shape and function.In humans, there are four basic types of tissue:epithelialconnectivemuscular andnervous 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.

What is another name for 'adipose' tissue?
Adipose tissue is simply fat; the tissue itself is a form of loose connective tissue with adipocytes that store the fat. The fat itself is used to store energy for future use, should things like glucose and protein become unavailable.
Help!! I have some body system question!!!! :(?
I am working on my BODY SYSTEM packet right now and i have run across a few questons i don't know i don't expect you to answer all of them. But PLEASE ANSWER WHAT YOU KNOW, IT WOULD HELP OUT SO MUCH :) 1. List the four basic types of tissue in the human body, describe their function and give examples of where they are found. 2. List and describe the levels of organization for the human body. 3. What are the functions of the skin 4. Discuss why cigarette smoke is dangerous.
Blood does not flow in what part of the human body?
there are capillaries in teeth, although enamel of teeth doesn't have any blood flow. Nail beds (the pink stuff) do have blood flow, but the hard outer part does not. Hair does not have blood flow. Nipples and eyeballs both DO have bloodflow
What are the tissues of the skin and their functions?
Cells group together in the body to form tissues - a collection of similar cells that group together to perform a specialized function. There are 4 primary tissue types in the human body: epithelial tissue, connective tissue, muscle tissue and nerve tissue. Epithelial Tissue - The cells of epithelial tissue pack tightly together and form continuous sheets that serve as linings in different parts of the body. Epithelial tissue serve as membranes lining organs and helping to keep the body's organs separate, in place and protected. Some examples of epithelial tissue are the outer layer of the skin, the inside of the mouth and stomach, and the tissue surrounding the body's organs. Connective Tissue - There are many types of connective tissue in the body. Generally speaking, connective tissue adds support and structure to the body. Most types of connective tissue contain fibrous strands of the protein collagen that add strength to connective tissue. Some examples of connective tissue include the inner layers of skin, tendons, ligaments, cartilage, bone and fat tissue. In addition to these more recognizable forms of connective tissue, blood is also considered a form of connective tissue. Muscle Tissue - Muscle tissue is a specialized tissue that can contract. Muscle tissue contains the specialized proteins actin and myosin that slide past one another and allow movement. Examples of muscle tissue are contained in the muscles throughout your body. Nerve Tissue - Nerve tissue contains two types of cells: neurons and glial cells. Nerve tissue has the ability to generate and conduct electrical signals in the body. These electrical messages are managed by nerve tissue in the brain and transmitted down the spinal cord to the body.
What is the difference between Epithelial Tissue and Connective Tissue?
Epithelial tissue covers the entire outside of your body, lines the surfaces of organs, and forms glands. They regulate the transfer of heat, water, and nutrients between the interior and exterior of structures.They act as a protective barrier that form layers of closely packed cells. Connective tissue consists of cells that are loosely arranged in a liquid, jellylike, or solid matrix. There are four types of connective tissues: loose - soft extracellular matrix; provides padding (adipose tissue) dense - fibrous extracellular matrix; provides connections(tendon, ligaments) supporting - firm extracellular matrix; structural support and protection (bone, cartilage) fluid - liquid extracellular matrix;provides transportation (blood)
