Step-by-step explanation:
Maintaining homeostatic blood pH is crucial for the proper functioning of the body. The nephron, which is the functional unit of the kidney, plays a key role in regulating blood pH by filtering and excreting substances that can affect pH. In response to the high concentration of phosphoric acid, ketones, and lactic acid in Keanu's blood, the nephron would carry out the following processes to help maintain homeostatic blood pH:
Filtration: The first step in the nephron is filtration, where blood is filtered through the glomerulus to form a filtrate. Substances like waste products (including phosphoric acid, ketones, and lactic acid) are filtered out of the blood and into the filtrate.
Reabsorption: Normally, essential substances like glucose and ions are reabsorbed back into the bloodstream as the filtrate passes through the renal tubules. In the case of Keanu's blood
