How does the structure of epithelial tissue relate to the function?
How does the structure of epithelial tissue relate to its function? Epithelial tissue is bound together with several sheets of tissue which is good because if one layer of tissue gets destroyed there will be more to protect the outside contaminations from getting inside.
What is the job 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.
How does muscle adapt to carry out its function?
They have structures that are adapted for their function. For example, muscle cells bring parts of the body closer together. They contain protein fibres that can contract when energy is available, making the cells shorter.
What are the 2 main types of epithelial tissue?
There are two kinds of epithelial tissues: Covering and lining epithelium covers the outside surfaces of the body and lines internal organs.
What is the function of epithelial tissue in the human body?
Epithelial tissue functions to absorb, secrete, and excrete substances. In the intestines, this tissue absorbs nutrients during digestion. Epithelial tissue also has a sensory function as it contains sensory nerves in areas such as the skin, tongue, nose, and ears.
How are plant tissues adapted to their function?
Plant cells, tissues and organs are adapted to their functions. The stem, root and leaves form an organ system that transports substances into, around and out of a plant. Plant leaves are adapted for photosynthesis, and the exchange of gases required for the process. The structure of the tissues is related to their functions in the plant.
Why are cells tightly packed together in epithelial tissue?
The cells in epithelial tissue are very closely packed together and joined with little space between them. With its tightly packed structure, we would expect epithelial tissue to serve some type of barrier and protective function and that is certainly the case.
How are ciliated epithelial cells adapted to their environment?
Certain single-celled organisms such as ciliated protozoans use the back and forth motion, like oars on a boat, to propel the cell through its environment. The epithelial cells lining your respiratory tract are covered in cilia. Rather than moving the cell, the cilia on epithelial tissue move things in the environment.
