This essay will explain the function of the respiratory‚ digestive and cardiovascular systems and how they work together to produce nutrients and oxygen to the cells for cellular respiration (energy for the body) The first system in the body is the digestive system. When food enters the mouth the salivary glands secrete saliva which mixes with the food. This makes it easy to chew and swallow. Once the food has been chewed enough the food travels down the oesophagus to the stomach. Once the food

process of converting the food you eat into nutrients that your body can use for energy‚ growth and cell repair needed for survival. The digestion process not only takes in nutrients but also eliminates the waste products from your food.

Respiratory System WebQuest Introduction The primary function of the respiratory system is to supply the blood with oxygen. The respiratory system does this through breathing. Breathing is a natural process that we use to obtain oxygen‚ unlike eating or drinking to get energy. When we breathe‚ we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system’s means of getting oxygen to the blood. The respiratory tract is responsible for taking the gases

Biology Summer Task Our digestive systems contain glands. These glands produce enzymes. Enzymes are catalysts. Catalysts make chemical reactions happen quicker and easier. Digestive enzymes help us to break down food easier. Our bodies make lots of different digestive enzymes. Each enzyme breaks down a particular food. When an enzyme has broken down one food molecule‚ it can then break down another molecule of the same kind. It can do this over and over again. It makes the reaction happen without

are regulated by the autonomic nervous system‚ or involuntary‚ meaning that we do not consciously have to contemplate digestion for digestion to occur. With this being stated‚ it would make sense that almost the entire gastrointestinal tract is made up of smooth muscle. Smooth muscle is very distinctive from the other types of muscle in the body due to the fact that it is not controlled consciously‚ but unconsciously regulated by the autonomic nervous system through the release of neurotransmitters
