Ions‚ atoms and molecules are constantly in random motion; this is mainly marked in liquids and gases as they are further apart. When there is a small amount of molecules of a substance in an area and a large number is another area and they have no barrier between them the random motion causes numbers to even up; this is called diffusion. Diffusion is when molecules move from a high concentration to a low concentration. The concentration gradient is when the concentration is different for each

P4 – Explain the role of the kidney in the homeostatic control of fluid balance Homeostasis is how our body works to keep the internal environment constant. The kidneys play a role in the control of fluid balance. For this assignment I will be discussing the gross anatomy of the renal system and the kidney. Renal System The renal system is a group of organs that work together to produce‚ store‚ and release urine. It consists of 2 kidneys‚ ureters‚ the urinary bladder‚ urethra and renal vessels which

Lab 7: The Kidney’s Role in Fluid Balance Introduction The renal system performs a vital role in homeostasis. The kidneys’ ability to retain valuable constituents and expel metabolic wastes from the body enables this system to regulate the volume‚ osmolarity‚ and pH of body’s internal fluid environment (Sherwood‚ 2007‚ p. 511). The functional unit of the kidney‚ referred to as the nephron‚ is composed of both tubular components—Bowman’s capsule proximal tubule‚ loop of Henle‚ the distal tubule

Urine Specific Gravity Each day an adult excretes between 800ml and 2000mL of urine. This amount varies depending on various conditions that can influence fluid loss and fluid intake. For example‚ the loss of fluid through heavy sweating in hot weather reduces urine amounts. The minimum volume of urine needed to remove body wastes from an adult is about 500mL/day. The specific gravity of urine can be an indicator of disease or disruption in normal metabolism. As you recall from our earlier discussions

IV Fluid Balance Assessment 1. According to the reported data‚ my water intake is still short about 100ml/day‚ and the fluid mostly comes from water. In order to prevent the dehydration‚ which might eventually cause coma and death if severe‚ as well as increased burden on kidney and decreased blood electrolyte caused by over-consumption of water‚ the better choices will be juices that are fortified vitamins‚ such as orange juice where usually vitamin A and calcium and some other B-complex vitamins

find out if there is a relationship between fluid intake and urine output‚ by measuring my daily fluid intakes and urine outputs. Hypothesis: The volume of urine I will produce will be at least half of the volume of fluids I will drink‚ due to the body’s ability to carry out a water balance just as one would have on oxygen‚ carbon dioxide to maintain a healthy and working body. For example if I drink 1000cm3 of fluids then the expected amount of urine I should produce would be around 4000 cm3 to

Case Study: Urinary‚ Fluid & Electrolyte balance The cardiovascular system and the urinary system are intimately entwined. When the cardiovascular system experiences stress‚ the urinary system can be directly impacted. For example in hemorrhagic shock‚ when the body is rapidly depleted of circulating blood volume‚ the kidneys are often one of the first vital organs affected due to lack of perfusion. The kidneys are dependent on the sufficient cardiac output that the heart delivers. So when the

Urine production If body fluids are hypo osmolar‚ then kidney will produces hypo osmolar urine. (Dilute urine) If body fluids are hyper osmolar (dehydration) then kidney produces hyperosmolar urine. (concentrated urine) In the renal cortex the osmolarity of interstitial fluid is 300mOs/L going to 1200mOs/L in the papilla. From the cortex to the papilla there is an increasing hyper osmolarity of the interstitial fluid. Cortico papillary osmolarity gradient. Urine with osmolarity more than 300mOs/l

Decreased pH in the blood is generally known as acidosis. The body cells continuously respire and release carbon dioxide. The lungs may fail to efficiently expel the CO2. This condition is known as alveolar
