I am going to produce a written assignment which is meant to show an understanding of the main tissue types and the role they play in two named organs. 

Main tissues of the body

There are varies different organs in the human body like for example the heart, lungs, kidneys and skin, which is actually the largest organ in the human body. Each organ in the body at least contains two different types of tissue that function together for a common purpose.

Tissues are formed by a group of cells that carry out a similar function.

These are the 4 main tissues in the body

  • Epithelium tissue
  • Connective tissue
  • Muscle tissue
  • Nerve tissue

Epithelium tissue- is usual found in the outer layer of the skin and the inside of the mouth. Epithelium tissues’ are mostly known for these function to protect and keep different organs in the body separate from each other and also keep the organs in place. 

Connective tissue includes many different types of tissues, which are found in the body, for example fat tissue, ligaments and blood is also considered as a connective tissue. Connective tissue helps to give support and strength to the body, as most types of connective tissue include fibrous strands of protein collagen which adds strength and support. Another name for connective tissue is glue.

Muscle tissue contains specialized proteins called actin and myosin which help muscles contract and relax. Muscle tissues are found all around the body. They help with body movement. Muscles are vital as without them there, there would have been no pump in our hearts, as the heart also is a massive muscle which squeezes and relaxes blood and oxygen are our bodies.

Involuntary muscle are found in internal organs such as the heart, and is a muscle which contracts without conscious control and is usually found in the walls of internal organs such as stomach and intestine and bladder and blood vessels. Involuntary muscle contains protein filaments, and doesn’t follow the pattern that is created in striated muscle and therefore does not produce the banding characteristics of striated muscle.

Voluntary Muscles are muscles attached to bones and the skeleton of the human body. Voluntary muscle is also known as striated, ‘striated’ meaning striped because each individual fibre has dark parts and light part, ...
