P 200 Explain The Digestive System
The cardiovascular system which impacts deeply on human consciousness. The heart and the body’s blood-transporting network of arteries, veins, and smaller vessels form the circulatory or cardiovascular system. As blood is continuously pumped out from the heart and around the system in two circuits, it carries oxygen and vital nutrients to all parts of the body and removes harmful waste products from tissues. (P.169)
What is the hepatic portal system?(Answer if your last name starts A – M)
The hepatic portal system is an arrangement of blood vessels between two different sets of tissue. Blood from the stomach, spleen , intestines and pancreas drains into a number of veins which merge to become the portal vein. The vein transports gastrointestinal …show more content…
The gas exchange of oxygen and carbon dioxide takes place in the alveoli. Tiny blood capillaries surrounding the alveolar walls allow oxygen to be carry into the bloodstream. In exchange, carbon dioxide waste diffuses from blood into the alveoli from where it is exhaled. (P. 200)
The Digestive System
Explain the function of the digestive system (everyone)
The digestive system is the physical ad chemical breakdown of food. Following ingestion, food and fluids are processed by the digestive organs so that nutrients can be absorbed from the intestines and circulated around the body. Any residue of food that is not digested is solidified and eliminated from the body in the form of feces. (P.207)
What are digestive enzymes and what do they do? (A-M)
Enzymes are protein molecules that increase the speed of chemical reactions in the body. They work by combining with and altering the molecules of other chemical substances. There are thousands of different types of enzyme with varied structures that determine their particular activity. The digestive enzymes secreted in the digestive tract split large molecules of food into small units for absorption.
