The iPhone 6s and 6s Plus are made from a 7000 Series aluminum alloy, which is stronger and more durable than the 6000 series used in the previous-generation iPhones. Apple's also updated the devices with stronger glass, made using a dual ion exchange process.
Two important sacral nerves to the functioning of the bladder and bowel are the pudendal nerve and the pelvic splanchnic nerve. Through a series of reflexes and signals the nerves and the bladder and bowel coordinate with the pelvic floor muscles and external urinary and anal sphincters.
The parasympathetic nerves that regulate digestion for the liver, stomach, pancreas, small intestine, and part of the large intestine are vagus nerves (the tenth cranial nerve). Unlike the splanchnic nerves, these nerves carry messages directly to the brain.he hormones that control digestion are produced and secreted by various organs along the tract. These hormones cause the various chemicals that aid in digestion to be released or prevented from being released.
