Outline the structure of the main tissues in the body
Unit 5 : P2
Connective Tissue
Connective tissue is made up of a number of layers formed together and there are different types of connective tissue. These are:
1. Aerolar
2. Adipose
3. Fibrous
4. Bone Tissue
5. Cartilage Tissue
6. Blood Tissue
7. Hemopoietic
Connective tissue is useful for a variety of things. Some examples of the uses of this tissue type are storing fat, repairing tissue damage and protecting us against diseases.
Muscle Tissue
This tissue is made up of a large number of cells. There are three different types of muscle tissue and each of these three has their own function:
1. Skeletal: This type of muscle tissue covers your
Skeleton to give your body its shape.
2. Smooth: This type of muscle tissue works by contracting in order to do things such as pushing food through our bodies.
3. Cardiac: This type of muscle tissue squeezes the blood out of our hearts by contracting and it then relaxes to fill it back up with blood.
Nervous tissue
This tissue is found in the spinal cord, the brain and the nervous. The nervous tissue is seen as the ‘brain’ of the tissues as it is responsible for all informational functions. The nervous tissue contains neurons, and these neurons can never divide therefore can never be replaced if/ when they die.
The functions of the nervous tissue are to receive nutrients from our blood, however it is protected in a shell so cannot receive all of the nutrients. The nervous tissue/ nervous system are used to carry sensory system information to the brain.
Epithelial Tissue
This tissue is formed by a large number of very tightly packed cells which make up this tissue. These tightly packed cells cover the whole of the body surface. The cells in this tissue continuously divide in order to create new ones.
There are two types of epithelial tissue: SIMPLE EPITHILIAL and SQUAMOUS EPTHILIAL. Organs; The heart and
