from an area of high concentration to an area of low concentration and this is due to chemical energy. Osmosis is the passive transport involving water molecules, these molecules move from areas of high concentration (hypertonic) to areas of lower concentration (hypotonic) via a permeable membrane which is the cell membrane , this means that only certain solutes can pass through the membrane. Intracellular body fluids are fluids found inside the cell, these fluids contain water and other solutes. Extracellular body fluids are fluids outside of the cell and can be divided into two types of fluids interstitial fluids and blood plasma . In order to get fluid balance in the body , process such as diffusion and osmosis takes place , osmotic pressures…show more content…
The substances that were filtered out in ultrafiltration such as glucose , amino acids are all beneficial so are transported into the bloodstream as well. Sodium ions and Chlorine ions are transported into the capillary In the other side hydrogen ions are secreted into the proximal convoluted tubule . Further into the nephron in the loop of henle reabsorption takes place in the descending and ascending limbs of the loop , the descending limb is permeable to water so as the filtrate from the proximal convoluted tubule filtrates down the descending limb water (H20) by osmosis . When the filtrate reaches the bottom of the loop the concentration has increased so as the reaches the ascending limb which is impermeable to water so NaCl leaves the ascending limb passively. The distal convoluted tubule is here the final adjustments happen , this tubule is impermeable to water sodium are reabsorbed whereas potassium is secreted. The collecting ducts is the final stages on where reabsorption takes place before the filtrates leaves as urine , the NaCl is reabsorbed back into the blood while urine is
