...Course: Bio 102 Instructor: Marina Yoffe Assignment: Lab report (Introduction and discussion) Introduction The way in which different organisms acquire oxygen in exchange for carbon dioxide has truly evolved. The exchange of carbon dioxide for oxygen is essential for the survival of organisms that need to produce the energy molecule ATP through the process of cellular respiration. Respiration (breathing) is the way organisms exchange gases with their environment (White and Campo 2004). During cellular respiration organisms break down energy rich macromolecules such as starch to make ATP in a chemical reaction where oxygen and water is involved (Ege R. and A. Krogh 1914).The use of oxygen is very important; therefore the efficient acquisition of oxygen is very necessary for an animal’s survival. Depending on what type of organism is involved, our sources of oxygen are different and occur through diffusion. Terrestrial animals obtain oxygen through the air while organisms living in water depend on the oxygen from the water. Unlike terrestrial animals, the amount of oxygen for animals living in water is limited based on the amount of oxygen that has dissolved in the water. Since an adequate amount of oxygen is necessary, animals developed respiratory organs to help them ventilate and obtain as much oxygen from their respected sources as possible (W.C and R. Oesting 1934). One organism that has developed an efficient way of acquiring oxygen is fish. Fish use a counter-current exchange...

...femoral site for extended lengths of time (Watson, & Gorski, 2011). Nursing management Cardiac catheterization has evolved into an outpatient procedure that has vital implications for nursing management, and patient and family education. Nurses must be alert to recognize patients at high risk, detecting problems, and anticipating complications. Laboratory and other diagnostic testing are needed in advance of the procedure to assist with the evaluation process. Discharge typically occurs within six hours of the procedure, not allowing enough time for patient and family education about post procedure patient care and approaches to maintain patient safety in the immediate post procedure period at home (Moser & Riegel, 2008). Cath lab staff duties can be classified into scrubbing, circulating, and monitoring as the following:- The scrub nurse assists the cardiologist with the instrumental side of the procedure. The nurse must have a thorough knowledge of sterile surgical technique to diminish possible infectious processes, so hand washing is mandatory before each procedure, then dress in a surgical gown, and wear sterile gloves, then flush catheters, guide wires, and other invasive equipment that may be used during the procedure, and help with catheter exchanges, wires, and other devices. The scrub may also inject medications such as nitroglycerin, heparin, IIB-IIIA platelet inhibitors, and other medication through the catheters (Watson & Gorski...

ANSWER and DATA in the LAST PAGE (all the way in the bottom, Lab 4 Worksheet) 2. If two athletes have the same vertical jump height, but differ in body mass, which jumper is more powerful? Explain. So if we assume that both their heights are the same the person that is heavier will be exhibiting much more strength as it takes more force to lift more weight to the same height. Also if we assume that both people generate force at the same rate, as in if it takes them half a second from the beginning of their jump for their feet to leave the ground then the heavier person will do more work in the same amount of time, generating more power and thus making his jump more powerful than the other person. 3. The power generated...

...What is the function of enzymes in a living system? Enzymes speed up metabolic reactions necessary for life. Without them certain vital processes would not take place and the body would be unable to function. Difference enzymes work better under different conditions. Where in a human body might it be beneficial to have enzymes work in very acidic environments? In areas, like the stomach, that have a pH of two would benefit by having enzymes that function well in acidic environments. An example of such an enzyme is pepsin. There is a large amount of catalase found in a human liver. Does the liver break down more hydrogen peroxide in the summer or winter? Explain your answer. More hydrogen peroxide will be broken down in the summer compared to the winter because higher body temperatures equals more enzyme activity. Many enzymes end with “ase”. Come up with your own enzyme, then name and explain what this enzyme does. Draw the enzyme and the substrate in the space provided below along with the enzyme-substrate complex. My enzyme would be olestrase. It would break down the lipid olestra and make it usable for the human body. Recent advances have allowed humans to mass-produce certain enzymes. Research one such enzyme and explain how this enzyme has been used to benefit society. Coenzyme Q10 (ubiquinone) is a naturally occurring substance which has properties potentially beneficial for preventing cellular damage during myocardial ischemia and reperfusion. It plays...

...NUTRITION 121 HUMAN NUTRITION LABORATORY BACKGROUND AND METHODS MODULE #1 BODY COMPOSITION Late Labs: 10 point deduction! A report submitted >1 week late, will receive 0 points for the lab!! Written and edited by: Karon Felten and Nutrition 121 TA’s With Special Thanks to: Chris Pritsos Ph.D. Nutrition Department Chairman ABSTRACT: In nutrition, there are many factors that influence an individual’s health and body weight, such as heredity, food selection, eating behaviors, and physical activity. Scale weight is not always a good indicator of body fat, lean mass, body water or overall health (1). This laboratory experience will give students the opportunity to conduct physical assessments by evaluating body weight and body composition. To determine body weight and body composition, techniques such as bioelectrical impedance analysis (BIA), body mass index (BMI), waist circumference, wrist circumference for determining frame size, and a scale will be utilized. Students will also evaluate their own risk for cardiovascular disease and assess cardiovascular health in volunteers by measuring heart rate, filling out a heart disease risk score form, and estimating oxygen consumption and energy expenditure through a technique known as the Queens College Three-Minute Step Test. BACKGROUND: Your body is made up of the six essential nutrients: water, fat, protein, carbohydrates and various vitamins and minerals. Many factors can influence an individual’s...

...the rationale for holding/discontinuing this medication at that time? (5 points) Ibuprofen can increase the risk of bleeding during surgery because it prevents platelets from aggregating and decrease clotting. It is recommended to stop NSAID a week prior to surgery due to the life spam of platelets. 3. The patient also reports that he took hydrochlorothiazide and Tylenol last night (October 31) and that the doctor’s office told him not to take his hydrochlorothiazide this morning. What is the rationale for holding this medication at this time? (5 points) Hydrochlorothiazide is a diuretic for the treatment of hypertension. The mechanism of action impact electrolytes like potassium. According to the pre-op work up serum potassium level is below normal range which indicate a risk for developing hypokalemia. 4. Identify the potential cause(s) of the serum potassium laboratory result. (3 points) The serum potassium level is slightly below the normal range, this result can be attribute to the use of diuretics like hydrochlorothiazide which mechanic of action is to inhibit the absorption of potassium, sodium and chloride. 5. The nurse calls the surgeon with this lab value. What does the nurse expect the physician to order? (3 points) What does the nurse need to consider with this order? (3 points) Due to the potassium low level, it is mostly expected to receive an order of potassium via IV. A nurse consideration at the time of administrating potassium IV is to give it slowly to prevent...

...correlated with fibrosis (Dowman et al., 2009). The production of these cells has been linked with hepatocellular carcinogenesis according to Dowman et al., 2009. The inflammatory injury to the liver causes a fibrosis in the hepatic cells. If the inflammatory process continues and the liver is unable to produce mature hepatocytes the liver will then progress into cirrhosis. The two major risk factors for developing NAFLD are IR and metabolic dysfunction. Both of theses risk factors are frequently seen in the hospital setting. The advanced practice nurse (APN) must be able to identify NAFLD risk factors and be familiar with the complex pathophysiology associated with such a widespread disease. Natural History of Disease Process The true natural history of nonalcoholic fatty liver disease is not very well unknown. The landmark research study by Adams and associates begun in Olmsted County, Minnesota in 1980. The study published by Adams et al 2004, followed 435 patients with fatty livers for 20 years. The conclusion was that patient with NAFLD had a higher rate of mortality than the general public and correlated cirrhosis, impaired fasting blood sugar and advanced age with NAFLD (Adams et al., 2014). As NAFLD research expands it has been generally believed that the progression begins with steatosis of the liver coupled with increasing inflammation and fibrosis, thus ultimately ending with cirrhosis. Insulin resistance throughout research is a common factor in the NAFLD disease process...
