Kidney Function Introduction and definition of terms: The kidneys are the main organs in the urinary system. They filter waste products out of blood from the renal artery. These are then excreted. Useful solutes are reabsorbed into the blood. They also have a major homeostatic role in the body, and help to control the water content (osmoregulation) and pH of the blood. Homeostasis is the maintenance of a constant internal environment within a living organism. Excretion is the removal

include, the kidneys, ureters, urinary bladder, and the urethra. This paper will go into depth about the Anatomy and Physiology of The Urinary System and will explain what each of the four parts do for the body. It will also, include some diseases the urinary system can have. To begin, the anatomy of the Urinary System is composed of the Kidneys, the ureters, the bladder, and the urethra. The kidneys look like beans and are located in the posterior wall of the abdominal region, the kidneys filter waste
pig's blood from its fetus to its placenta. It is at the pig's placenta where it exchanges waste in return for nutrients with the mother's blood. The Umbilical Vein transports the blood back from the placenta to the fetus. Activity #1- External Anatomy Our pig is a male because the urogenital papilla
system’. It is made up of two kidneys, two ureters, a urinary bladder and a urethra that produce, store and then excrete urine out of the body. For the purpose of this assignment the structure and functions of the urinary system will be explored focusing on the kidneys, in order to explain the importance of maintaining homeostasis. Homeostasis is the regulation of internal processes and substances that maintain a constant internal environment within the body. The kidneys lie on the posterior abdominal
on the kidneys that the overconsumption of alcohol can cause. Throughout the essay, I am going to identify and discuss the different effects that alcohol abuse can cause to the renal apparatus. In this essay, I am going to identify the different changes that can happen at different levels. Ethanol can affect the regulation of the different electrolytes, hormones and the concentration of substances that need to be either reabsorbed or secreted. Alcohol can also cause changes in the anatomy of the
the amount of water in your blood, osmolarity makes sure to maintain fluids in our blood in such that our cells are in isotonic state and pressure. The kidneys secrete two hormones, renin controls the blood pressure and erythropoietin (EPO) causes the bone marrow to produce more red blood cells. Metabolic waste in the blood are regulated in the kidneys defaulting the regulation of acid/base balances in the blood by producing urine and becoming acidic. 2. Nitrogenous waste is the elimination of metabolic
ATP, which is the “energy molecule.” Ketones are produced as part of the process. When people eat fewer carbohydrates, more ketones are generated. Some of these ketones (acetoacetate and B-hydroxybutyrate) are used for energy; the heart muscle and kidneys prefer ketones to glucose. Most of the cells in the body can use ketones as part of their energy. However, this is not true for acetone which cannot be used, and is excreted as waste mostly in the urine and breath. Sometimes a metabolic condition
The excretory system is a passive biological system that removes excess, unnecessary materials from the body fluids of an organism, so as to help maintain internal chemical homeostasis and prevent damage to the body. The dual function of excretory systems is the elimination of the waste products of metabolism and to drain the body of used up and broken down components in a liquid and gaseous state. In humans and other amniotes most of these substances leave the body as urine and to some degree exhalation
describe the kind of homeostasis involved. Fluid balance is the balance of input and output of body fluids in the body. Electrolyte balance is a concentration of electrolytes in the body that are controlled by a variety of hormones and most are in the kidney and adrenal glands Martini (2014). Acid-base balance is maintained 3 ways: chemical buffers (phosphate, carbonic-bicarb, and protein), respiratory system, renal system (Martini, 2014). Why does maintain fluid balance in older people
your kidney. Cystitis is a common female problem. Its is estimated that 50% of adult women experience at least one episode of dysuria; half of these people have a bacterial UTI. SYMPTOMS Cystitis signs and symptoms often include: A strong, persistent urge to urinate. A burning sensation when urinating. Passing frequent, small amounts of urine. Blood in the urine. Passing cloudy or strong-smell urine. Discomfort in the pelvic area.
Purpose/Abstract A minks body function has similarities as a humans body, therefore, we use minks as a understanding of the human anatomy. Introduction Anatomy classes often use minks for dissection to help teach students about the anatomy of a body. Dissections are the cutting apart and separation of tissue and it is useful and follows comparative anatomy, the study of different species similar to the human body. Mink dissections are useful because they teaches students through visually and hands
UNIT 1: INTRODUCTION TO ANATOMY Introduction What is Anatomy? Anatomy is the science that studies the body. What is Physiology? Physiology is the science that studies the function of the body What is homeostasis? Anatomy and Physiology are closely related because each tissue, organ, system in the body has a function. All the body organs and systems in your body work to maintain the proper function of your body in equilibrium (homeostasis) using positive and negative feedback mechanisms • Example
Anatomy of a False Confession Depending on what study is read, the incidence of false confession is less than 35 per year, up to 600 per year. That is a significant variance in range, but no matter how it is evaluated or what numbers are calculated, the fact remains that false confessions are a reality. Why would an innocent person confess to a crime that she did not commit? Are personal factors, such as age, education, and mental state, the primary reason for a suspect to confess? Are law enforcement
The purpose of this study is to examine the cost effectiveness of mid level providers, such as physician assistants, compared to physicians. In order to thoroughly evaluate the difference in cost one must look at more than one aspect of the physician assistant versus the classic physician. From a purely economic standpoint one needs to address the cost of education, differences in the way patients are treated based on the kind of medicine practiced and the cost of employment between physician assistants
Friends: our novel kinship during medical school. It is said that friendship is a single soul dwelling in two bodies. Well, everybody must have friends don’t they? One is in great affliction if one thinks that one can live by his own. Most of us medical students are studying abroad or quite far from our family. Some of us even went as far as crossing continents and studying in Europe or the Middle East. One cannot help to stop and pause to argue that the next closest to us after our family would
Grey’s Anatomy Have you ever thought about how many people watch television every day? “Close to 20 million people tune in every week to the show Grey’s Anatomy” (askville.amazon.com). Some of the viewers watch the show every week and are dedicated fans. Others just watch when they can catch it, but even when they don’t watch it every time, it still has an effect. Viewers who are not regular watchers tend to look at more of the medical information. They stop on the channel because they like medical
The early hominins of Africa were similar to other hominins in gross anatomical features, however, there were differences between the early hominins of Africa and other hominins, such as those found in Asia and other parts of the world as discovered in fossil remains. Not only were there some differences in the anatomical structures, there were also evidentiary differences in their culture and environmental factors in their lives, especially as the species evolved. Below, I will compare some of
Anatomy & Physiology of the case scenario Having described the scenario, this essay will now focus on the anatomy and physiology during Laura’s third stage. After the delivery of her baby, Laura’s uterus continued to contract and retract due to the effect of oxytocin on the myometrium. Herman (2000) and Herman et al. (2002) describe the placental separation in three stages; latent, contraction/detachment and expulsion. During the latent phase Laura’s myometrium begun to contract and retract. During
Motor movement development has been a topic of controversy for the last century. The feud began in 1906 when Sir Charles Sherrington published The Integrative Action of the Nervous System. The work summarizes over two decades of research, revealing many fundamentals of neural science for the very first time (Burke, 2007). He was not only the first to suggest that the nervous system was a complex network of separate neurons, coining the term ‘synapse’, but he also was the first to discuss reflex
