Tissues Tissues are sets of the same cells carrying out particular functions these include; epithelial‚ connective‚ muscle and nervous. Epithelial tissues are the inside layer of internal and external surfaces and body cavities‚ including ducts carrying secretions from glands. They may be composed of some layers of cells‚ called compound epithelia or just a single layer which is known as simple epithelia. The lowest or bottom layer of cells is attached to the basement membrane for support and

A nonliving material‚ called the intercellular matrix‚ fills the spaces between the cells ii. What can be found in this material? The intercellular matrix may contain special substances such as salts and fibers that are unique to a specific tissue and gives that tissue distinctive characteristics iii.

by Ma Cho Cho Lwin & Ma Eaindra Win TISSUES Tissues are group of cells that work together to perform a particular functions. There are four main type of tissues. They are: I. Epithelial tissues II. Connective tissues III. Muscle tissues IV. Nervous tissues EPITHELIAL TISSUES Simple epithelial tissues This tissue has only one cell layer. Compound epithelial tissues This tissue has more than one cell layers. EPITHELIAL TISSUES Epithelial tissues cover the whole surface of the body

to exercise. This is caused by a number of factors working in combination‚ including; Muscle fibers reduce in number and shrink in size. Muscle tissue is replaced more slowly and lost muscle tissue is replaced with a tough‚ fibrous tissue. These changes in the nervous system cause muscles to have reduced tone and ability to contract. Bone is living tissue. As we age‚ the structure of bone changes and this

Task2: The main tissue types of the body and the role these play in two named organs of the body. P2: Outline the structure of the main tissues of the body There are many different types of cells in the human body. These cells would not be able to function on their own‚ they are all part of a large organism that is called - you. The two named organs that I have chosen for this assignment are the intestines and the heart. Tissues All cells group together within the body to form tissue‚ a collection

BIOS251 Week 3 Lab Exercise Tissues and Integumentary System 1. Describe the characteristics of epithelial tissue. (5 points) The most basic characteristics of the epithelial tissue is that it covers the surfaces of the body whether internal or external. It acts as a protective covering or boundary for such surfaces‚ including the outer layer of the skin‚ as well as the inner surface of the hallow organs like the stomach‚ colon‚ and blood vessels. Other characteristics is that it is made

Compare and Contrast Sommia Khan Dr. Doumen Exocrine versus Endocrine glands: The similarities between exocrine and endocrine glands are that they are both glandular tissues. Glandular tissues are generally composed of cuboidal cell or columnar cell. Exocrine glands release substances like sweat and saliva through ducts on to the surface of the body. Exocrine glands include merocrine sweat glands‚ apocrine sweat glands and holocrine glands. Merocrine sweat glands‚ also known as eccrine sweat glands
