. Urine Analysis Lab Report Objectives: To learn what tests can analyze a person’s urine and what they find Chem – 9 Test Specific Density Microscope Analysis of Urine To analyze a urine sample Examine presence of normal/abnormal elements Use urine sample to find specific gravity, pH, and chemical parts To have a better understanding of filtration, reabsorption, and secretion, and see how they affect urine production. Background: There is a lot of importance that comes with testing urine. Many different diseases can be tested for, (i.e. diabetes) and a urinalysis can provide a lot of useful information to physicians. Simple tests can immediately be taken from simply looking at a urine sample; color, odor, transparency, etc. By looking at the color of urine, things such as hydration levels can be tested. The clearer urine is, the more water that is present. Also, with the use of a microscope, particles like casts and sugar can be detected. The presence of too many certain particles can help to indicate that an infection/disease may be present. There are countless tests that can be taken during a urinalysis that can help to show any abnormalities in the urine and rest of the body. The process of producing urine and removing toxins from the body occurs in the excretory.

. environment of the body by selectively excreting or retaining various substances according to specific body needs. The process of urine formation and adjustment of blood composition involves three processes: glomerular filtration, tubular reabsorption, and tubular secretion. The first part of the process of urine formation occurs in the glomeruli which act as filters, allowing water, glucose, salt and waste materials to pass through to the Bowman’s capsule but preventing and red blood cells and plasma proteins to pass through. Reabsorption occurs in the proximal tubules of the nephron. Water, glucose, amino acids, sodium and other nutrients are reabsorbed into the bloodstream in the capillaries surrounding the tubules. Water moves via the process of osmosis: movement of water from an area of higher concentration to one of lower concentration. Tubular secretion is the final step in the process of urine formation which transfers materials from peritubular capillaries to renal tubular lumen and occurs mainly by active transport. ADH is secreted by the posterior pituitary (neurohypophysis) when there is a decrease in water concentration (increase in osmolarity) which will cause an increase in water reabsorption (decrease in osmolarity). ADH most important function is to conserve the fluid volume of your body by reducing the amount of water passed out in the urine. When there is a decrease in serum sodium levels (decrease.

. send signals to the medulla of the brain stem. The medulla will then stimulate the autonomic nervous system to adjust the mean arterial pressure by altering both the force and speed of the heart’s contractions, as well as the total peripheral resistance. The most important arterial baroreceptors are located in the left and right carotid sinuses and in the aortic arch (Marieb, Hoehn 2013). The kidneys and adrenal cortex also play an important role in maintaining blood pressure. Renin-angiotensin system (RAS) is a long-term adjustment of arterial pressure by using the kidneys to compensate for loss in blood volume or drops in arterial pressure by activating a vasoconstrictor known as angiotensin II. Aldosterone is a steroid hormone released from the adrenal cortex in response to angiotensin II and stimulates sodium retention and potassium excretion by the kidneys. Since sodium is the main ion that determines the amount of fluid in the blood vessels by osmosis, aldosterone will increase fluid retention, and indirectly, arterial pressure (Marieb, Hoehn 2013). Baroreceptors in low pressure receptor zones (mainly in the venae cava, pulmonary veins, and in the atria) result in feedback by regulating the secretion of antidiuretic hormone (ADH/Vasopressin), renin and aldosterone. The resultant increase in blood volume results an increased cardiac output by the Frank–Starling law of the heart, in turn increasing arterial blood pressure. Blood pressure.

.  The Effect of Metal Ions on Lichens Casey Stinnett ESC 1510 October 30, 2014 Introduction Lichens are a sybiotic association of fungus (mycobiont) and algae (Pediastrum boryanum . The fungus engulfs the algae, then supplies carbs, nitrogen, and vitamins while the algae photosynthesizes. This unusual relationship enables the lichen to grow in environments where neither fungus nor algae would normally be able to solely survive. They are found on every continent, ranging all the way from the freezing Arctic to the sweltering grasslands of Africa. Even though they can live in such extreme conditions, they do require clean air. This is why they are excellent environmental indicator. An indicator species is an organism whose presence or absence reflects the overall health of an environment. Lichens flourish where there is good air quality; however, they cannot survive where the air is polluted and toxins loom. This is because they have no stomata, or pores, to shut to keep the toxins out; therefore, absorbing all of the pollutants in the air. Because they are such unique organisms, they accumulate different metal anions in the air than other organisms, like plants do, for example. Lichens attract toxic metal ions. An ion is a charged atom. If the ion has a positive charge, it is a cation. An ion with a negative charge is an anion. During the ion exchange process, Hydrogen, an anion, is released and metal cations move in. This process occurs when lichens are.

What effect does increasing the afferent radius have on glomerular filtration rate and pressure? Both the rate and the pressure increase as you increase the afferent radius. 2. What effect will decreasing the efferent radius have on glomerular filtration rate? When I decreased the efferent radius, it increased the filtration rate. Please see table below: Summary: In this Activity, I learned/observed that: the nephron has three important jobs on filtering the blood. Glomerular Filtration speed can be affected by the efferent radius and by the afferent radius.

. Daphny Maldonado Bio Lab 2107 Kiah Britton W 10-12:30 Is H20 Bad for You? Abstract: In the village of Gopher Hollow there’s a cluster of Blue Baby Syndrome. There were four infants affected by this cluster. The families from the infants would collect their water from wells. We have to determine what’s the source of the high levels of nitrites in the water. The four sources that could be the point of contamination are a new subdivision, textile plant, an organic farm, and a mountain lake. We had to find the concentration of each known standard and unknown standard. We did this by using a spectrophotometer. The results were the following, the organic farm with a herd of 50 cows and a 10 acre field of zucchini had the highest levels of nitrites. Introduction: Blue Baby Syndrome is a condition that affects many infants. This condition makes the baby’s skin turn blue because of the lack of oxygen. This condition can exhibit lethargy, vomiting and not being able to breathe. It can even lead to death in rare cases. This condition is caused by the excess amount of nitrate that is then converted into nitrite by the digestive system. The hemoglobin then reacts with the nitrites to form Methemoglobin. Methemoglobin is not a problem in adults since they have an enzyme that converts methemoglobin back to hemoglobin. Infants don’t have many of the enzyme to convert methemoglobin to hemoglobin, resulting in Blue Baby Syndrome. For example in Gopher.
