EXERCISE 9: RENAL SYSTEM PHYSIOLOGYHere is 9 got 95% Still need help on final 132 | ACTIVITY 1: The Effect of Arteriole Radius on Glomerular Filtration Answers 1. According to your lab manual‚ in humans the glomerular filtration rate (GFR) ranges from _____ to _____ ml/minute. 80 140 2. When the radii of both the afferent arteriole and efferent arteriole were set at 0.45mm‚ the GFR was approximately ______ ml/minute. a. 40 b. 60 c. 80 d. 120 C. 3. True or

Neurophysiology of Nerve Impulses ACTIVITY 1 The Resting Membrane Potential 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. If the extracellular K+ increases then the concentration of intracellular K+ will decrease causing a decrease in the steepness of the concentration gradient and fewer K+ ions would be drawn out. 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative

LAB ONE: Exercise 4 – Endocrine System Activity 1: Metabolism and Thyroid Hormone Part 1: 1. The normal rat had the fastest basal metabolic rate. 2. The metabolic rates differed between the normal rat and the surgically altered rats because the surgically altered rats didn’t have a thyroid or pituitary gland and therefore‚ the normal rat had a faster basal metabolic rate. The results turned out to be the way I predicted them to be. 3. T3 and T4 would be missing in the animal’s blood

ACTIVITY 1: THE RESTING MEMBRANE POTENTIAL 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out the neuron through the K+ leak channels? When the diffusion is greater on one side‚ the other side will slow down. 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value. How well did the results compare with your predictions? There are two potassium’s for every sodium so the increase of potassium will make it more

Cardiovascular Diseases Cardiovascular disease is defined as a disease that affects any area of the cardiovascular system‚ including the heart and blood vessels‚ and covers a range of diseases such as arteriosclerosis‚ atherosclerosis and coronary heart disease. Diet plays a vital part in the prevention and control of these diseases however other manageable factors such as smoking and physical inactivity also contribute to the diseases if not controlled correctly. However corrective action or

CARDIOVASCULAR FITNESS Cardiovascular fitness is frequently considered the most important aspect of physical fitness because those who possess it are likely to have a lessened risk of coronary heart disease – the number one killer in our society. Cardiovascular fitness is also referred to as cardiovascular endurance‚ cardio-respiratory capacity and circulatory fitness. Regardless of the word used to describe it‚ cardiovascular fitness is complex because it requires fitness of several body systems

Cardiovascular disease is a general name for a wide variety of diseases‚ disorders and conditions that affect the heart and sometimes the blood vessels as well. Risk factors for developing cardiovascular disease include having hypertension‚ diabetes‚ high cholesterol‚ obesity‚ and a sedentary lifestyle. Other risk factors include being of African-American ancestry‚ male‚ drinking excessive amounts of alcohol‚ having a lot of long-term stress‚ smoking and having a family history of a heart attack

Cardiovascular Disease Information HCA 240 February 22‚ 2013 Gioia Scoppoa Cardiovascular Disease Information Cardiovascular disease refers to conditions that narrow or block blood vessels. These conditions can lead to a heart attack or stroke. According to Richard P. Lewis M.D. (Can Cardiovascular Disease be prevented)‚ “Cardiovascular disease is the common chronic illness in our society.” Coronary artery disease is a disease that supplies the muscle with blood. The blood flow can become
