The most critical part‚ the Cable and Fiber Preparation where the fiber is mounted‚ is the ferrule. The Ferrule is a long‚ thin cylinder with the fiber mounted in the center hole. The center hole is sized to match fiber’s cladding diameter which is usually 125um. When fiber connector ferrules are made from several types of materials including ceramic(Zirconia)‚ stainless steel and plastic. The ferrule’s job is to center and align the fiber and protects it from mechanical damage. The end of fiber

The atrial contraction is the part of the trace that shows the refractory period 8. Does summation occur? No summation 9. Why is it important that summation not occur in heart muscle? Summation would increase the Heart muscle contractions which would lead to heart attack. Activity 2: Vagus Nerve Stimulation 1. Describe

Beginning at 40 seconds‚ with the pH at 7.52‚ respiratory alkalosis occurred. 7. Did the PCO2 level change during the course of this run? If so‚ how? Yes the PCO2 levels did fluctuate over the course of this run decreased from 40mm Hg to 19.7mm Hg 8. If you observed an acid/base imbalance during this run‚ how would you expect to renal system to compensate for this condition? Renal compensation for alkalosis means the kidneys will correct the basic conditions by increasing H+ absorption and by increasing

6.1.1 Explain why digestion of large food molecules is essential. There are two reasons why the digestion of large food molecules is vital. Firstly‚ the food we eat is made up of many compounds made by other organisms which are not all suitable for human tissues and therefore these have to be broken down and reassembled so that our bodies can use them. Secondly‚ the food molecules have to be small enough to be absorbed by the villi in the intestine through diffusion‚ facilitated diffusion or active
