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)

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

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.

    The digestive system is made up of organs that break down food into protein, vitamins, minerals, carbohydrates, and fats, which the body needs for energy, growth, and repair. After food is chewed and swallowed, it goes down the esophagus and enters the stomach, where it is further broken down by powerful stomach acids. From the stomach the food travels into the small intestine. This is where your food is broken down into nutrients that can enter the bloodstream through tiny hair-like projections. The excess food that the body doesn't need or can't digest is turned into waste and is eliminated from the body.…

    It can be analysed that the two body systems work together. Which are the respiratory system and the cardiovascular system. Oxygen is inhaled and enters the respiratory system. It travels down into the lungs through the trachea. Once inside the lungs, the gas enters the alveoli and diffuses through the alveolar wall. After it diffuses through the capillary wall, it enters the cardiovascular system. Oxygen then binds with haemoglobin forming oxyhaemoglobin and is then transported around to cells within the body. Carbon dioxide is transported as a waste product within red blood cells through the cardiovascular system. This needs to be exhaled…

    The cardiovascular system, also known as the circulatory system, is composed of the heart, blood vessels, and blood. The term cardiovascular refers to the heart (cardio-) and blood vessels (vascular). The term circulatory refers to the circulation of the blood. The heart is a muscular pump and its regular contractions send blood into tough, elastic tubes called arteries, which branch into smaller vessels and convey oxygen-rich blood through the body. The arteries eventually divide into tiny capillaries, which have such thin walls, that oxygen, nutrients, minerals, and other substances pass through to surrounding cells and tissues. Waste substances flow from the tissues and cells into the blood for disposal. The capillaries join and enlarge to create tubes that eventually become veins, which take blood back to the heart. Vessels carrying oxygenated blood (usually arteries) are shown in red and those carrying deoxygenated blood (usually veins) are blue.…

    The digestive process is important in maintaining the lives of living organisms and in providing them with needed energy and nutrition. Groups of organs, such as the mouth, esophagus, stomach, intestines, pancreas, and gal bladder work together to perform this complex task. Digestion is the process of breaking down food from large molecules into small ones to make it easier for absorption. The three major steps involved in the digestive process are ingestion, digestion, and absorption.…
