...Cell membrane: The cell membrane surrounds the cytoplasm of a cell and its job is to protect the inside of a cell by only allowing certain substances into the cell and keeping other substances out. It also helps to support the cell and maintains its shape. Nucleus: This is the biggest part of the cell and is the part of the cell which acts like the brain. It is not always in the middle of the cell but will be placed within the cytoplasm. In some cases a cell may have many nuclei and these are called multinucleate and are usually in muscle cells. In red blood cells, the nucleus is lost during development and is the only cell that is able to survive without a nucleus. The nucleus includes DNA. Cytoplasm: The cytoplasm of a cell is the material in the inside of the cell which is semi-fluid and is able to flow slowly and all chemical reactions within cells are carried out in there. Complex sugars including glycogen and melanin which is the pigment responsible for skin and hair colour are in the cytoplasm. These chemicals are the basic living materials that a cell needs. Organelles are the various components of a cell with a specific structure and function and are linked to miniature organs. These include: Mitochondria: These are small components within cells that perform different important functions in order to keep the body healthy. They make the energy that cells need to do to work correctly. An example of this is brain cells which need a large amount of energy in order...

...commentary (including specific examples) on the organisation of the human body. You must include cells, tissues, body organs and systems. Any images used must be sourced. The human body is extremely complex and contains different systems which work alongside each other but complete diverse tasks to keep our body’s functioning. Chemical level– is the simplest level within the structural hierarchy. The chemical level includes the tiniest building blocks of matter, atoms, which combine to form molecules, like water. In turn, molecules combine to form organelles, the internal organs of a cell. Cellular level – the cellular level is made up of the smallest unit of living matter, the cell. The individual cells may have some common functions but vary widely in size and shape. Each type of cell carries out a set of unique tasks within the human body. Tissue level – tissues are groups of similar cells that have a common function. A tissue must contain two different types of cells. The four basic tissue types in humans include epithelium, connective, muscle and nervous tissue. Each tissue has a characteristic role that is vital in the complete function of the human body. Organ level – an organ is a structure composed of at least two different tissue types that perform a specific function within the body. Examples of this include the brain, stomach and liver. Complex functions begin to emerge at this level. Organ system level – one of more organs work in unison to accomplish...

...ANATOMY AND PHYSIOLOGY P2, P3 4/27/2015 Khadra Ali | P1 – Outline the functions of the main cell components The human body is made up of millions of tiny cells that can only be seen under a microscope, cell also vary in shape and size. Cells are the basic structural of all living things. The human body is poised of trillions of cells. They give structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body’s hereditary material and can make copies of them. Cells all have different sizes, shapes, and jobs to do. Each cell has a different function. The actual definition of cells is the smallest structural unit of the body that is capable of independent functioning, it consisting of one or more nuclei; it has a cytoplasm, and various organelles which are all surrounded by a cell membrane. There are four main parts to a cell; Plasma/Cell membrane, Cytoplasm, Nucleus and Cell Organelles. Plasma/Cell membrane: The plasma/cell membrane is a phospho-lipid-protein bi-layer; the lipids are small fatty molecules in two layers (bi-layer) with larger protein molecules inserted at intervals partly or completely through the bi-layer. The lipid molecules are phospholipids, the two lipid chains are insoluble in water and the phosphate head is water soluble. The fluid which surrounds the cells and the cytoplasm are watery environments next to the phosphate heads. Protein molecules create channels...

...P2. Outline the structure of the main tissues in the human body. A tissue is a group of similar cells. An organ contains different tissues, that work together to carry out different functions. The four main types of tissues are: 1) Epithelial tissue 2) Nervous tissue 3) Muscle tissue 4) Connective tissue Epithelial Tissues. This is located on the internal and external body cavities and surfaces, including tubes and channels (ducts), carrying discharge from glands. They may be made by several layers of cells, which is called compound Epithelia or a single layer is called simple Epithelia. The lower/bottom part of the cell layer is attached to the basement membrane for support/connections. There are nerve supplies to the epithelia but they are provided by diffusion. As they are on the surface, their volume to growth is a lot quicker than other tissues. Simple Epithelia. Simple Epithelia is one thick layer of tissue made from cells, it can be one of these three different shapes: 1. Squamous 2. Cuboidal 3. Columnar Squamous are found in: * Lung alveoli. * Blood capillaries. * Bowman’s capsule of nephrons. Cuboidal can be found in: * Kidney tubules. * Sweat ducts. * Glands that are like the thyroid gland. * Breast tissue. Columnar cells are found lining: * The trachea and bronchi. * Villi in the small intestine. Compound epithelia. The compound epithelia contain two or more layers of cells. This...
