when the number of molecules becomes evenly distributed and the net movement slows down and will eventually stop. However whilst this is happening the random motion is still occurring it’s just not in one direction. Diffusion takes place within the body through the cell membranes. Although these are freely passable to the diffusing molecules providing the barrier are thin. In the lungs there are two simple squamous epithelial cells which separates the dissolved gases in the alveoli from the blood

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

First‚ fluids are absorbed through the gut and into the bloodstream faster when their permeability closely matches that of body fluids such as blood. Sports drinks contain dissolved minerals (sodium‚ etc.) and carbohydrates‚ whereas water doesn’t‚ so water doesn’t reach the bloodstream as quickly. Sodium and other nutrients also play important roles in regulating fluid balance in the body. In other words‚ they help determine how much

interstitial fluid‚ and intracellular fluid are identical‚ but the quantity of each substance varies among the compartments. The most striking differences are the low protein content in interstitial fluid compared with intracellular fluid and plasma and the fact that sodium and chloride ions are largely extracellular‚ whereas most of the potassium ions (approximately 90%) are intracellular. This unequal distribution of ions results in a voltage difference across cell membranes. Extracellular fluid can be

Monica Mahmoudi 02072798 Bandaruk Mon-Wed 12:45 PH Balance in the Human Body As we all know every solution is either acid or alkaline. Alkaline is often called base. These solutions can be anything from body fluids‚ to fruits‚ vegetables‚ seawater‚ beverages you name it. Acid and alkaline is measured in pH. It starts as low as zero being very acidic and works its way up to fourteen being the most basic. The pH of our stomach is 2‚ obviously to digest food‚ wine is 3.5‚water is 7(neutral)‚ arterial

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

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

describing the differences between intracellular fluid and extracellular fluid in the first observation is completely obvious. When reading the words intracellular and extracellular it can be seen that one is the interior of the cell and the other is the exterior of the cell. Intracellular fluid is restricted to the interior of the cell‚ and the cell membrane is the borderline of cytosol or cytoplasmic matrix. The compartments of the intracellular fluid are very important to know‚ as it contains mostly
