Hugh Christie School The cardiovascular system + Respiration System OCR level 3 Sport Bertie Migo 9/24/2013 Within this report I will be describing what the cardiovascular system is‚ how it works‚ and what it consists of. I will also be talking about the respiration system‚ what it is‚ how it works and what it consists of. P1 – Describe the Structure and function of the Skeletal System At birth‚ a new born infant has around 300 bones‚ whereas the average adult has only 206 bones

osmolality and the term tonicity referrers to the osmolality of a solution. The cells in the body are exposed to three different solutions classified as isotonic‚ hypotonic‚ and hypertonic. Isotonic solutions have the same osmolality as body fluids. They do not change the size or shape of the cells‚ leaving them in a balanced state. Examples of isotonic fluids include 0.9% saline‚ Lactated Ringers (LR)‚ D5W‚ 0.225% saline‚ D5/0.225%‚ Whole Blood‚ and Packed Red Blood Cells. 5% Dextrose‚ Normal Saline

Diffusion and Osmosis Using “Deshelled” Chicken Eggs Introduction In order for a cell to survive and function‚ it must maintain an internal steady state of environment in the midst of an ever-changing external environment. This steadiness is provided by the regulation of the movement of materials across its plasma membrane. Since not all substances penetrate the membrane equally well‚ the membrane is said to be differentially permeable. (IS) Diffusion is the tendency of molecules

experiment‚ the main element to consider is hypertonic‚ hypotonic and isotonic solutions and how they relate to osmosis. Osmosis is the process where a fluid passes through a semipermeable membrane‚ which moves from an area which the solute is present in high concentrations. As a result of osmosis‚ there will be an equal amount of fluid on either side of the barrier‚ creating an isotonic solution. When cells are placed in an isotonic solution‚ the movement of water outside of the cell is exactly balanced

and the nerve conduction velocity. We will test an earthworm nerve‚ frog nerve‚ and two rat nerves on the oscillator. The factors that helped determine action potential were the Bio-amplifier‚ stimulator‚ ethanol‚ and voltage. C. Materials • PhysioEx CD-Rom‚ computer‚ lab manual. D. Methods I.

The thymus in the human is located inferior to the larynx in the neck and as a cat grows older the thymus almost disappears completely. PhysioEx Exercise 28B - QUESTIONS 1. a.

1. How does a cell become differentiated? A cell becomes differentiated by using only the DNA that it needs. 2. Give an example of 2 differentiated cells. Two examples of differentiated cells are lysosomes and mitochondria. Lysosomes are small so they can move throughout the cell effectively. Mitochondria have a lot of surface area to make more energy 3. (Essay) What does it mean to be specialized? Explain how the structure of the cell determines its function. Give at least 3 examples. Being specialized

Other resources include linked web pages on the "Resources" page and the histology tutorial on the PhysioEx 7.01 CD. Remember‚ for the practical‚ you are expected to: 1) Identify the tissues 2) Know where the tissues are found 3) Know one function for the tissues Epithelial tissue | | Simple squamous epithelium Epithelial tissue that lines
