BIOS 255 Week 4 Lab: #7 Effect of Exercise on Arterial Pressure and Vascular Resistance LABORATORY REPORT Activity 7: Effect of Exercise on Arterial Pressure and Vascular Resistance PREDICTIONS 1. During exercise: MAP will increase 2. During exercise: CO will increase 3: During exercise: SVR will decrease MATERIALS AND METHODS 1. Dependent Variable: heart rate (HR), stroke volume (SV), blood pressure (BP) 2. Independent Variable: level of activity 3.
A. List Joseph’s risk factors and create a brief summary of the information you have so far. Identify how his risk factors would affect cellular function. The risk factors for Joseph are history of hypertension, poor diet, weight gain, stress, family history of vascular disease, and smoking. These risk factors affect cellular function by slowing down the amount of oxygen and blood flow the cells are receiving.
If this fails, a pancrelipase and sodium bicarbonate solution may be instilled in order to "digest" the clog. Metabolic complications: Metabolic complications of enteral nutrition are similar to those that occur during PN, although the incidence and severity may be less. Careful monitoring can minimize or prevent metabolic complications. Refeeding syndrome: Refeeding of severely malnourished patients may result in "refeeding syndrome" in which there are acute decreases in circulating levels of potassium, magnesium, and phosphate. The sequel of refeeding syndrome adversely affect nearly every organ system and include cardiac dysrhythmias, heart failure, acute respiratory failure, coma, paralysis, nephropathy, and liver dysfunction.
MATERIALS AND METHODS Measurement of Threshold Stimulus 1. Dependent Variable is the contraction force 2. Independent Variable is the stimulation voltage 3. Controlled Variables are the muscle fiber length, temperature, freq of stimulation. Effect of Muscle Length on Contraction 1.
By blocking beta receptors, the heart rate will be slowed and reduces demand for oxygen and contractility. By slowing the heart rate, diastole will increase and the time of coronary blood flow will increase. With a decreased heart rate and contractility, the amount of work the heart has will also decrease. Calcium channel blockers are used to treat
8. Describe the importance of this order. Include affect on force of contraction and fatigue. This order is set up in order to increase the amount of force necessary for the work load while also limiting fatigue. The slow oxidative fibers are set up to help with weaker amount of force but are very resistant to fatigue.
C. I think that the component of the reflex arc that is most likely to be damaged in Nick’s situation is the integrating center because one of more regions within the CNS relay impulses from sensory to motor neurons, so the impulses are never reaching the motor neurons and effectors. D. The division of the autonomic nervous system that would be affected and causing Nick’s GI symptoms would be the parasympathetic division because it controls the interworking of the body. E. The autonomic nervous system controls blood pressure by sensing a rise or fall in the blood pumping in the veins, thus causing them to constrict or dilate as needed. F. The area of that brain that interacts with the autonomic nervous system during physical stress to initiate rapid heart and respiratory rates, elevated blood pressure, and profuse sweating is the prefrontal cortex. G. The autonomic receptors that regulate closing of sphincters and relaxation of organ walls are Adrenergic (Alpha 1) receptors.
Compression is also be used for helping with severe cases of shin splints, ensuring that it does not get worse. The effectiveness in doing rest, ice, and compression, either separately or all together, is very high and should allow athletes to recover from shin splints at a much higher rate. Stretching and strengthening the legs for treatment should only be done after rest to prevent further strain on the tibia. Stretching and exercising is another great way to help strengthen tibia. In this, stretching and exercising the leg muscles, the muscle will be able to increase endurance, and prevent of muscle fatigue, thus preventing
Formal Definition: Muscular Dystrophy is a disease that causes muscle weakness over time. Attitude: Everyone should know the disease of Muscular Dystrophy. My interpretation of this term is significant because I want other to know how this disease can take away some people freedom. Topic Sentence: Muscular Dystrophy is a disease that cause muscle weakness and muscle loss over time and the disease gradually take away some people freedom. Outline: Support 1: Muscular Dystrophy is a disease that weakens the muscles that move the body.
Physiological ‘Stress’, marked by the secretion of glucocorticoid hormones and often referred as the negative consequence of an animal’s failure to cope with changing environment, in certain circumstances, is a need in ensuring survival and allowing adaptation to such change (Wielebnowski et al. 2002; Moberg 2000; Mostl and Palme, 2002; Menargues et. al. 2008). But if it persists for a prolonged duration, the continuous action of high concentration of Glucocorticoid on liver, muscle and adipose tissues, loses it adaptive value, adversely impacts the muscle and bone impairing the endocrine and immune function, degrading the body mass, individual fitness and causing reproductive failure resulting the long-term behavioural changes as supported by the Cort-fitness hypothesis (Munck et al.
