The overall function of the digestive system as digestion and absorption of food stuffs, and the general activities of each digestive system organ is; Ingest, digest, absorb, defecate.
Ingestion involves placing food into the mouth, propulsion involves propelling food from one organ to the next using peristalsis. Mechanical digestion involves the physical fragmenting food into smaller particles. Chemical digestion refers to breaking down food molecules to building blocks by enzymes. Absorption is the transport of digested end products to blood or lymph; and finally Defecation which involves the elimination of indigestable material from GI tract by anus.
<h3><u>Answer;</u></h3>
b) cycle both carbon and oxygen
<h3><u>Explanation</u>;</h3>
- Photosynthesis and cellular respiration are complementary processes by which living things obtain needed substances.
- They both consume and create the same substances (water, glucose, oxygen, and carbon dioxide) but in different ways.
- <em><u>Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. </u></em>
- <em><u>While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.</u></em>
