Four Main Types of Tissues in the Body: Definition, Functions and Examples of Tissues

The cells form a continuous sheet without intercellular spaces. The matrix of bone contains fibers and mineral deposits. The bone marrow may be of two types: 1 Yellow bone marrow and 2 Red bone marrow. Lymph contains 94% water and nearly 6% solid particles which include proteins, fats, carbohydrates and other substances. The cavity is bounded by conĀ­centric layers called bony lamellae.

Mono-carboxylic acids, containing a long hydrocarbon side chain. Image: By OpenStax College wikimedia. They are compactly arranged without inter-cellular spaces between them. Depending on the nature of the matrix the cartilages are divided into two main cateĀ­gories: i Hyaline and ii Elastic cartilages. The Urinary System includes the kidneys, the ureters, thebladder, and the urethra. The parent cells of the vascular cambium produce both xylem and phloem. Through the lamellae pass numerous smaller chanĀ­nels from the narrow cavity; these are called Haversian canals.

The evidence, found with the body, including weaponry and equipment allow opportunity to investigate the technology of past civilisations. Tissues combine to form organs. Vascular Tissues : It Includes blood, lymph and bone marrow Fig. The Cells are cuboidal or columnar in relaxed state. Examples include the mucous membrane which lines body cavities. They are responsible for growth in length of the plant and increasing the size of the internode, They result in branch formation and growth.

All organs are built of these four tissues, which have consistent characteristics and arrangements from organ to organ. When epithelial tissue is made up of a single layer of cells, it is called simple epithelial tissue and when it is many-layered it is called comĀ­pound or stratified epithelial tissue. Epithelial Membranes An epithelial membrane is composed of an epithelial layer attached to a layer of connective tissue. Four types: epithelial, connective, muscle and nervous. Cuboidal epithelium has cells whose height and width are approximately the same.

The end walls, unlike vessel members in xylem, do not have openings. Polysaccharides play important roles in cells such as energy storage animal glycogen and structure support plant cellulose. . A system is a group of organs each of which contributes its share to the function of the body as a whole. Stratified epithelium is a multi layered epithelium. As cell proliferation progresses, three major cell lineages are established within the embryo. It provides elasticity and tensile strength to almost all the parts of the body.

This concept is more than just a convenient intellectual construct. Embryonic Origin of Tissues and Major Organs External Website View this to learn more about stem cells. We are composed of several different types of human body tissue. The upper layer cells might be keratinised, dehydrated to protect from heat, microbes, wear and tear, chemicals etc. The muscles help in movement, grinding of food and movement of food through the gut intestinal smooth muscles do this while the muscles of the chest help in respiration. In trees and other woody plants, rays radiate out from the center of stems and roots and appear like spokes on a wheel in cross section. The cells within a tissue share a common embryonic origin.

What are the four types of tissue and their functions

four main types of tissue

The Types of Tissue We have determined that we are made up of four different types of tissue. This muscle allows the synchronization of the heart beat. Epithelial tissue is classified based on the number of cells, the shape of those cells, and the types of those cells. This type of membrane may be found encapsulating an organ, such as the kidney, or lining the cavity of a freely movable joint e. Examples include the mucous membrane which lines body cavities. It is to be remembered that a nerve cell receives message through dendrites but always sends information through the axon. But when there is load, they stretch and become flat to accommodate the substance urine.

These membranes encapsulate organs, such as the kidneys, and line our movable joints. In most other types of stratified epithelium, the upper layer is non-keratinised. The activity of this cambium results in the formation of secondary growth. Simple Epithelia Simple epithelium consists of a single layer of cells. There are different types of tissues in the human body; other animals and plants have tissues too but theirs will be described in another article. Muscle tissue allows the body to move and nervous tissues functions in communication. Proteins Proteins are made of C, H, O, N and S.
