The human lungs are amazing feats of nature; they help us pump vital oxygen through airways and into the bloodstream every second of the day. Without this ability, humans could not survive on Earth. This paper explores the major parts of the respiratory system, the main purpose and how it plays a crucial role in the human body. The organs that make up the respiratory system, the function of these organs, as well as the relationship between the respiratory system and other systems within the human body. This essay will also describe the medical problems and diseases associated

The Respiratory System’s Vital Role in the Human Body
The respiratory system is made up of different organs that are responsible for taking in oxygen and releasing carbon dioxide as we breathe. The main purpose of the respiratory system is to supply the body with oxygen by delivering oxygen to the blood when we breathe. Oxygen is used by cells for the breakdown of nutrients, an activity that is necessary to supply energy to the cells and the body. Without oxygen, cells are unable to function properly. Oxygen deprivation, even for only a few minutes, can cause the brain and the heart to stop functioning, which could lead to death. The lungs serve a fundamental role in ensuring that carbon dioxide is

These important parts consist of the airways, the lungs, and the muscles of respiration, within these major parts there are certain organs that provide aid to help the respiratory system function properly. The nose is the primary opening where air first enters into the body. The nose is also responsible for our sense of smell, it also filters the air we inhale. After air is passed through the nose, it then travels to the pharynx (throat), the pharynx is a passageway that goes from the nose, to mouth and then leads to the larynx. The pharynx is also where the swallowing of food takes place. The larynx (voice box), the voice box is a hollow tube that is connected to the top of the windpipe, the larynx also serves a blocker to keep food from passing into the lower respiratory tract. When air passes through the trachea (windpipe), the trachea provides a clear airway so that air can enter and exit the lungs. There are small hairs that line the inner walls so that dust can be caught before air is inhaled, and is later exhaled by coughing. The bronchi are two tubes that are connected to a lung that stems from the end of the trachea. The bronchi allows air that comes in from the outside of the respiratory openings to pass into the lungs, the bronchi leads into each lung and then divides into smaller tubes which are called bronchioles. The bronchioles narrow themselves into
