Describe the basic anatomy of the human body affected by assisting and moving The human body is only able to assume it’s different posture and maintain its structure due to the skeletal system. The skeletal system is made up of bones which have an outer hard cortical layer and an inner soft trabecular layer made of cancellous bone. Within some long bone is the all important marrow from where all the blood cells originate after maturation. The skeletal system can be divided into 2 groups: 1.

Organisation of the human body. Jade Roberts. Barbara. P1‚ P2 AND P3. Health and Social Care level 3. 1 In this booklet I will be explaining what the main components and functions are of the cells. I will also be outlining the structure of the main tissues in the body and the gross structure of all the body systems. 2 The components and functions of cells. Cell membrane All organisms have something in common‚ they all have a cell membrane. The cell membrane is a barrier that separates a cell

of tissues in the human body that I am going to give examples of. These include the epithelial tissue‚ connective tissue‚ collagenous tissue and the nerve tissue. The first time of tissue is the epithelium tissue which has the function of helping to protect the body. There are four main types of epithelium tissues; squamous epithelial cells‚ Cuboidal epithelial cells‚ columnar epithelial cells and ciliated columnar cells. The squamous epithelium protects the linings in the body such as blood vessels
