i)=> In the duodenum, the bile juice enters the intestine from the common bile duct and adjacent to the opening of the common bile duct, the pancreatic duct opens into the duodenum and pours pancreatic juice into it.
=>The alkaline Bile neutralizes the acidic chyme that enters from the stomach, providing an alkaline environment for pancreatic enzymes to act and also emulsifies fats to give small fat droplets.
=>The three enzymes present in pancreatic juice are trypsin, steapsin and pancreatic amylase.
=>Trypsin converts peptides and proteins into smaller peptides, peptones and amino acids.
=>Steapsin or Lipase converts fat droplets into fatty acids and glycerol.
=> Pancreatic amylase converts starch into maltose.
ii) =>There is a great difference in diameter in the afferent (incoming) arteriole and the efferent (outgoing) arteriole from the glomerulus.
=> This causes very high hydrostatic pressure in the glomerulus in the Bowman's capsule, the blood plasma, leucocytes and smaller soluble materials such as glucose, urea dissolved in plasma squeeze out through the pores of the capillary network of Glomerulus.
=> This fluid is called the Glomerular filtrate and moves through the uriniferous tubule towards the proximal convoluted region.
=> This process is termed as ultrafiltration.
