Osmosis in Potato Tissue Experiment Background Information Osmosis can be defined as the movement of water across a semi-permeable membrane from a region of high water concentration to a region of low water concentration. The semi-permeable membrane allows small particles through it but does not allow large particles such as sodium chloride. Osmosis will continue until a state of equilibrium is reached i.e. there is no area with a higher or lower concentration than another area

Practical 1 Title: Tissue Processing Aim: To examine human cell and tissue under the microscope Introduction: Tissues from the body taken for analysis of diseases must be processed in the histology laboratory to produce microscopic slides that are viewed under the microscope. These tissues are usually fixed into paraffin. Microscopic analysis of cells and tissues requires the preparation of very thin‚ high quality sections mounted on glass slides and properly stained to demonstrate normal and abnormal

INTRODUCTION Tissue paper has been a significant part of our day to day life for the purpose of purity‚ cleanness and freshness. Facial tissue and toilet tissue has been the most widely used form of tissue paper. Facial tissue refers to a class of soft‚ absorbent‚ disposable paper that is suitable for use on the face. The term is commonly used to refer to the type of facial tissue‚ usually sold in boxes‚ that is designed to facilitate the expulsion of nasal mucus from the nose although it may refer

Tissue Expanders A tissue expander is a device that is made from elastic silicone rubber. During the mastectomy‚ this balloon-like device is placed after the surgeon removes skin and tissue to allow for placement of the tissue expander beneath the remaining muscle and skin of the patient’s chest. The tissue expanders are inserted either empty or with a minute amount of saline in them. As time passes‚ sterile saline fluid is added to the expanders: This is accomplished by inserting a small needle

human body is summarised as follows: Cells—> Tissues—> Organs—> Systems—> Organism. The same type of cells which carry out a specific function are organised into a tissue. For examples‚ a group of muscle cells form a muscle tissue while a group of nerve cells form a nerve tissue. They are organised to work together to perform specific functions as the result of cells in the human body do not work individually. An organ is a group of tissue that cooperates to carry out a specific life process
