What is another answer on describing how the digestive and urinary and excretory work together to maintain homeostasis?

Food and liquids are processed by the digestive system, after nutrients are absorbed during digestion, the urinary tract excretes waste products. This maintains oxygen homeostasis by making sure that CO2 is removed.

Explanation:

Homeostasis is the process of maintaining the chemical balance in all living things. The foods consumed and processed through the digsetive system and brought into the small intestines wear essential vitamins and bacterias are abosored into the lining; this is critical for the wellbeing of the organism and the continuation of homeostasis.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
