LAB EXERCISE: Diffusion and Osmosis Laboratory Objectives After completing this lab topic‚ you should be able to: 1. Describe the mechanism of diffusion at the molecular level. 2. List several factors that influence the rate of diffusion. 3. Explain why diffusion is important to cells. 4. Describe a selectively permeable membrane‚ and explain its role in osmosis. 5. Define hypotonic‚ hypertonic‚ and isotonic in terms of relative concentrations of osmotically active substances. 6. Discuss

reached. The steeper the gradient the faster the rate of diffusion. There are a few types of diffusion. Three (3) of those are: Facilitated Diffusion- refers to diffusion of substances across a cell membrane with the help of transport protein. Dialysis- refers to the diffusion of solutes across a semipermeable membrane. Osmosis- refers to the diffusion of the solvent across semipermeable membrane. The concept of diffusion is widely used in physics (particle diffusion)‚ chemistry‚ biology‚ sociology

into the urine. If a person experiences kidney failure‚ waste products can’t pass out of the blood‚ which causes waste to build up in their bodies. While a patient can choose to replace their kidney with a working one‚ dialysis is also an option in cases of kidney shortage. Dialysis provides the same functions a kidney does. It clinically purifies the blood as a replacement for the lost kidney‚ by separating the particles in a liquid of the basis of differences in their ability to pass through a membrane

AKNOWLEDGEMENT During the reflective study‚ there a lot of partier giving helpful hand to make and finish my reflective study. Therefore‚ it will be unfair if I put a side their contribution rather. Firstly‚ the special thank goes to my helpful Staff Nurse Suhaini. The supervision and support that he gave truly help the progression and smoothness of the internship program. Also thanks for your skill and knowledge that you have thought me in the progress of completing my research. The skills and

filtration and dialysis use a matrix-based fibrous material that provides a mechanism of separation in many homogeneous immunoassays. These materials may be coated with specific antibody-ligand to foster selection of specific materials or species. Certain labels use magnetic particles in conjunction with strong magnets to effect separation. Basic universally used separation mechanisms‚ outside of those incorporated in immunoassay‚ are centrifugation‚ filtration‚ and dialysis. Centrifugation

Rhabdomyolysis is a disease that is caused by muscle trauma and dehydration causing muscle fibers to breakdown into the bloodstream. This has a toxic effect on the kidneys and could be avoided in many cases. Dialysis as well as natural remedies can correct the disease if caught at an early stage. Muscular system diseases include muscle pain‚ weakness in the muscles and paralysis. There are various causes‚ for example hormonal disorders‚ auto-immune problem‚ genetic factor‚

I have a primary hospital location‚ but I also travel to other hospitals in the area. I enjoy this position for many reasons‚ one being that I have a lot of autonomy. Others and myself see working as an Acute Hemo-dialysis Nurse as a prestigious position. Although I work alongside other Registered
