3. For your organ system, describe how the system works at the organ level.

Answers

Answer: Lets take the circulatory system; a simple explanation would be that first the “arties” carry the blood from the “heart” through “blood vessels” to the “capillaries” who then release oxygen and nutrients and take carbon dioxide and the waste products of cellular respiration. When that is complete the “veins” take the blood and carry it back to the “heart”.

9. Which of the following best sequences the functions of the digestive system from start to finish? A. Absorption, ingestion, digestion, elimination B. Ingestion, digestion, absorption, elimination C. Elimination, absorption, ingestion, digestion D. Ingestion, absorption, digestion, elimination

Answers

Answer:

The correct answer would be B. Ingestion, digestion, absorption, elimination.

Digestion refers to the breakdown of complex compounds into simpler elements.

The process of the digestive system can be sequenced as:

Ingestion: Intake of food from outside the body. For example, in humans, food is taken in from a mouth.
Digestion: The breakdown of complex compounds into simpler elements. For example, polysaccharides, polypeptides, and fats are converted into monosaccharides, amino acids, and fatty acid chains and glycerol respectively.
Absorption: The digested food is absorbed and transported to all parts of the body. In humans, the small intestine is the major site of food absorption.
Assimilation: The nutrients are transported or distributed to all cells of the body where they are utilized for power generation.
Excretion: The undigested food is then excreted out of the body. In humans, the solid waste is excreted through the anus.

its B.
you eat it (ingest) it goes to your stomach (digest) then to your intestines where more nutrients are extracted(absorption) then to your and out your anus (elimination)
