When we think of respiration we usually think of inhaling oxygen and exhaling carbon dioxide. Assuming that all of the CO₂ we exhale is waste from cellular respiration, how does the carbon atom in CO₂ enter the body? Provide a explanation please<3

endocrine glands secrete hormones into the blood stream near them; the hormones then travel in our bloodstream until it reaches its destination, called a target cell, in distance parts of the body. in the target tissue, hormones lock onto the target’s plasma membrane, called the receptor site.

1. the energy lost to disorder metabolism     -entropy

2. related to or possessing motion potential     -kinetic

3. all of the chemical reactions in an organism required for maintenance of the processes of life entropy     -metabolism

4. possible; ability to go into action or perform work kinetic     -potential

5. the study of energy and its transformations thermodynamics     -thermodynamics

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
