In a basic physiology lab we ran an experhyment where we tested the renal clearance for sodium and water from a person with normal water intake and a hydrated person with 8 times the normal water intake. The results show that the clearance of water goes down very slightly and the sodium clearance increases sightly. Why? Hoping for a pretty detailed explanation. I understand the coupling of water and sodium reabsorbtion, but thought that water was supposed to be able to be excreted without affecting other solutes. Today I found out that… Sodium causes water retention

I’d prefer the answer come from the Marieb Anatomy and Physiology text book. If you can answer this, please cite the page number(s) you referenced. I was so happy to find this — I don’t have the book, but I do know the differences, if this helps: type 1 diabetes happens when your pancreas cannot produce insulin. No one really knows why your pancreas cannot produce insulin, but some believe that it might have something to do with an autoimmune disease (your immune system attacking itself). Type 1 diabetes is more prevalent among young people mostly between the ages of 7-16. Now, the reason you need insulin is so that your cells can pickup the sugar (glucose) from the bloodstream and transform it into energy. When insulin is not available, glucose levels stay high for long periods of time (high blood sugar). This in turn is dangerous because sugar starts taking water out of your cells, and because sugar can start scraping the blood vessels and eventually make them weaker. type 2 diabetes is also a high blood sugar disease, but this is a different story. With type 2 diabetes, your pancreas works just fine, but your cells are resistant to insulin. Type 2 diabetes is more prevalent in adults, and the causes are more genetic, or related to obesity, since obesity prevents the cells from utilizing the insulin. hope this helps

Steve Dale speaks with Michael Davis, DVM, MS, PhD, DACVIM (Large Animal Internal Medicine) at the 2009 ACVIM Forum & Canadian VMA Convention in Montreal. Dr. Davis studies the effects of exercise stress in animal models, particularly racing sled dogs. Dr. Davis’ research benefits not only four-legged athletes, but humans as well.

The way that exercises aid and great bodybuilding is something that is not that clear in the life of many bodybuilders. Body building exercises transform the physical structure and functions of the human anatomy. Exercise physiology constitutes studying such topics as the human body’s energy transfer processes, human body’s energy expenditure and the critical evaluation of the human body’s energy production abilities. Advanced studies in exercise physiology also evaluates the environmental effects on the human body physiology, the pulmonary system, the musculoskeletal system, the nervous system, the cardiovascular system, the ergogenic aids and the endocrine system which essentially entails studying hormone typology and concentration ratios.

Exercise Physiology by itself requires very diverse and deep knowledge of the human physique. It specializes in considering how the various reciprocal physiologic responses of the human body are prompted by body building exercises. Exercise physiology studies to body building also studies the converse interaction of these elements of the human physiology and also considers the adopted training methods and equipments used in body building workouts. Contemporary exercise physiologists specialize in clinical areas of the human body like cardiac rehabilitation, exercise testing and comparative analysis of prescriptions used by body builders, performance in different altitudes, researching body reaction to exercise especially as concerns relationships between performance and heat stress, fluid balance, motor functions during and after workouts, intracellular lactate mechanisms and plasticity of fibers located in body muscles.

Some researchers are even going into development and design of physical fitness training programs aimed at enabling prevention of common diseases and structural disability. Exercise physiology has picked up very well around the world. Exercise physiologists are highly paid specialists whoever are not only qualified in their area of specialization, but whoever understand the practice of body building inside out. Many exercise physiologists are professionals whoever originate more often from within the prestigious field of exercise science and whoever specialize in either physical fitness or general body health or exercise rehabilitation streams.

This has apparently indicated where the future of body building is headed, at least in terms of understanding how workouts are responded to by the human body. It is also apparent that exercise physiologists are critical and ideally suited to provide personalized professional advice for a body builder. Such advice may be about exercise as a successful treatment strategy especially in physical rehabilitation and also exercise as a valid preventative strategy used for preventing known diseases. More importantly for body builders however, the advice may constitute means of work hardening to establish and sustain functional muscles. Immense numbers of bodybuilders are therefore more informed about their own physiology than anywhere else in the world.

This has been a motivation to bodybuilders and a reason why body building is a prized sport among all the people of all races. As body building becomes a household name in all spheres of the global village, specialized knowledge especially in the necessary area of physical conditioning, mobilization and rehabilitation of the human body has greatly increased. The body building fraternity has attracted a modern evolution of exercise physiology specialists in the diverse distinct fields.

I find general biology to be boring. Will this hurt me while taking my anatomy and physiology course? I like anatomy a lot. Do you know what I found? It’s not going to kill you if you don’t take it. . . But it will defiantly help a ton. . Your probably going to have to put a little more time into studying because your going to have to learn any concepts that would have been taught to you in general bio overall. . You’ll be better off taking it and it will probably make it easier to understand what the teacher is saying and make it not sound like they are speaking a completely different language. . But you can still pass the class without it

I’m a physiology student,and I have a hard time understanding the urinary system. So i’m wondering if there’s a site or book that can help. I’m using Human Physiology(from cells to systems)-Lauralee Sherwood,5th edition. I had fun with the endocrine system and neurophysiology but this one,i don’t enjoy at all. What I found out was – vander’s renal physiology is a good book that’s a short read, but it is geared toward medical students. msg me if you want a copy

A little intro to renal Physiology

The length is no more than 10 pages of text, and we have to pick something that will allow us to describe physiological processes and mechanisms. Examples of past topics are diabetes, steroids, dive reflex, and seizures. I considered doing celiac’s disease, but realized that any processes I could describe were molecular. Any ideas. What I found out was – Here is a great one for any female, and my students have done it in the past. “How do birth control pills work”. If chosen, you will find yourself amazed at the answers relative to the negative feed back system of hormones and the endocrine system, how the placenta and even fetus maintain a pregnancy, how at point of conception mechanisms trigger to tell the body it has changed etc. I am sure you will find it to be a fascinating paper.

Individual myocyte contraction, however, is not necessarily isometric because individual myocyte are undergoing length changes. Individual fibers contract isotonically (i. E. , concentric, shortening contraction), while others contract isometrically (i. E. , no change in length) or eccentrically (i. E. , lengthening contraction). Therefore, ventricular chamber geometry changes considerably as the heart becomes more spheroid in shape; circumference increases and atrial base-to-apex length decreases. Well, I have your answer right here. The muscle cells in the heart do not contract at the same time, they contract at different times, Some contract whereas some relax. Therefor the size of the heart ventrical becomes more circular (like a ball) in shape, where the circumference: | | increases/gets bigger and the base to apex (bottom to top) length decreases (gets shorter) so the chamber gets shorter and fatter. This causes the blood in the chamber to be forced out the valve due to an increase in pressure.

I’m taking a second year physiology course on human organ systems and it is known to be the hardest paper in second year biomed. I go over the lecture slides, notes taken in class and read through relevant sections in the textbook recommended by the lecturers but in the tests they always seem to ask questions on things that I haven’t come across during my study. Does anyone have any tips on studying physiology? I’m sitting on an A- which isn’t enough to get into the honors course for next year . Well, I have your answer right here. 1] eat well, sleep enough, and exercise regularly to keep in good shape 2] review ALL notes/slides/texts daily, until you KNOW all this material, cold. 3] in text: review all material related to any and mostly all thing you learned 4] pray [ seriously ] please, God, let everything I learned show up on this exam.

I need a good book that has most info for a yr one student. I dont want anything too in depth. I have a vanders physiology book that isn’t very good and it doesn’t really sync with my lecture notes. so any good book that you know please recommend.. Thanks. After looking around, I learned — Principles of Human Physiology Cindi L. Stanfield, William J. Germann (covers all Basic principles in simpler terms and appealing pictures just might be what you need) Textbook Of Medical Physiology Guyton and Hall 11th edition (that’s a bit in depth but has all you need)

What happens differently to the physiology of people with diabetes during these situations than that of people without? I appreciate answers from anyone that would often share. However, I am especially looking for a somewhat technical explaination to aid my preparation for my upcoming EMT test. I think I found an answer. I’m a Type 1 Diabetic. The reason it is a more serious problem is because Diabetic’s bodies can’t handle a serious drop or raising of body temerature. For example, I’m not supposed to go into a hot tub because my blood sugar could drop low suddenly, which is very dangerous.
