Explain how the digestive, cardiovascular and respiratory systems are interrelated

Extracts from this document...

Introduction

Explain how the digestive, cardiovascular and respiratory systems are interrelated There are many systems within the body; all the systems have to work with one another in order to keep the body going and functioning as it should. The respiratory system, cardiovascular system and the respiratory systems are one of the few systems that are interrelated within the body and that work together in order to keep the body functioning. The respiratory and cardiovascular system both interrelate within the complex system of the human body, as firstly the oxygen that enters the body is inhaled and enters the respiratory system. This oxygen then travels through the trachea into the lungs following on to the alveoli and diffusing through the alveolar wall. ...read more.

Both systems also work together by providing nutrients in order for aerobic respiration to be carried out. The first part of the aerobic respiration is aided by both these systems as oxygen is inhaled by the respiratory system and glucose is broken down by the digestive system. (Glucose + Oxygen Carbon Dioxide + Water + Energy). The digestive system also acts as an aid for the respiratory system by nutrients to the diaphragm that is needed to assist the process of breathing. Furthermore, the digestive system can also interrelate with the cardiovascular system as nutrients that are provided by the digestive system are broken down by enzymes, the nutrients that are digested are essential for the human body as once they have been broken down they are absorbed into the blood and transported around the body. ...read more.

Conclusion

These chemicals are then transported around the body via the blood. The respiratory system provides the body with oxygen and removes unwanted carbon dioxide; this is done with the aid of the cardiovascular system. The cardiovascular system however, plays a huge role within the body and its functioning, as this is the system that is responsible for pumping blood around the body and carrying oxygen and nutrients around the body via the blood. Therefore, the respiratory system and the cardiovascular system also have to do their function so that this can happen. The food that is eaten is digested by the digestive system and the nutrients are given to the body via the blood, this is the same for the respiratory system as oxygen that is breathed in allows us to breathe as well as providing it to the rest of the body via the heart. ...read more.

As the cartilage rings are incomplete, it enables the trachea to be more flexible and thus facilitating the passage of food down the oesophagus.
