In general, connective tissue consists of cells and an extracellular matrix . The extracellular matrix is made up of a ground substance and protein fibers. So, in a more detailed way, all connective tissue apart from blood and lymph consists of three main components: cells, ground substance and fibers.
What is a structure made up 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. Many organs working together to accomplish a common purpose is called an organ system.
What are these tissues in turn made up of?
In the body’s organizational hierarchy, tissues occupy a place between cells and organs . That is, a tissue is a group of cells with a similar shape and function. In turn, organs (which make up the body) are comprised of various tissues.
How tissues are formed?
Tissues are formed from the assemblage of cells and intercellular materials in various proportions in which one component predominates . In nervous tissue as an example, nerve cells predominate while in connective tissues such as Ligaments and Tendons, intercellular fibrous materials predominate.
What are the 4 main types of connective tissues?
There are four classes of connective tissues: BLOOD, BONES, CARTILAGE and CONNECTIVE TISSUE PROPER . They are further subdivided into subclasses and types: I want you to be able to identify all the different types of Connective tissues as well as learn their locations in the body.
What are the 4 main types of tissues and their functions?
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).
Can tissues survive by themselves?
Without cell division, long-term tissue survival would be impossible . Inside every tissue, cells are constantly replenishing themselves through the process of division, although the rate of turnover may vary widely between different cell types in the same tissue.
What is tissue class 9?
Tissue is a feature of multicellular organisms. Complete Answer: ... A group of cells having similar shape and function act together to perform a specific function is known as a tissue. All the body parts are made up of tissues including the organs. Groups of tissues make organs.
Which is animal tissue?
Animal tissue refers to the group of cells of similar structure and function in animals. It is of following types: Epithelial tissue , Muscle tissue, Connective tissue, Neural tissue. Epithelial tissue covers the outer surface of the body and internal organs. It lines the body cavities. ... It is made of neurons.
Why are tissues so important?
Tissue is important as it helps the study of disease progression, determine prognosis , and identify the best treatments for different diseases. It has significantly contributed to the advancement of the medical industry.
What is called tissue?
Tissue is a group of cells that have similar structure and that function together as a unit. A nonliving material, called the intercellular matrix, fills the spaces between the cells. ... There are four main tissue types in the body: epithelial, connective, muscle, and nervous. Each is designed for specific functions.
What are the types of permanent tissue?
Simple permanent tissues are again classified into three main types. They are parenchyma, collenchyma, and sclerenchyma .
What are 3 types of connective tissue?
- Collagen fibers – most are type I collagen (most abundant protein in the body)
- Elastic fibers – contain elastin and fibrillin.
- Reticular fibers – contain type III collagen.
Which is not a connective tissue cell?
Which of the following is not an example of connective tissue? Explanation: Skin is composed of epithelial cells , and is therefore not an example of connective tissue. The major types of connective tissue include bone, adipose, blood, and cartilage.
Connective tissues come in a vast variety of forms, yet they typically have in common three characteristic components: cells, large amounts of ground substance, and protein fibers .
What are 4 functions of epithelial tissue?
Epithelial tissues are widespread throughout the body. They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands. They perform a variety of functions that include protection, secretion, absorption, excretion, filtration, diffusion, and sensory reception.
