“Cellular respiration is the oxidation of organic compounds that occurs within cells, producing energy for cellular processes (Dictionary.com, 2017)”. The process of cellular respiration occurs in three phases. The first process is called Glycolysis and is the breakdown of glucose in the cytoplasm. The next process is the pyruvate molecules transported into the mitochondria (aka “powerhouses” of the cells), the pyruvate are then converted into 2-carbon molecules and enter the Krebs cycle. Finally the energy enters the electron transport chain and the energy is used to produce ATP (CK-12, 2017). The lungs co-operate with cellular respiration as the lungs produce oxygen which is vital in helping the process of turning glucose into ATP.
The process of the respiratory system begins at the nasal cavity and mouth where air is inhaled. The air then passes through the sinuses located in the skull which regulate the humidity and temperature as someone breathes (Zimmermann, Live Science, 2016). The air is filtered in the trachea (windpipe) and then enters the lungs through a system of pipes called the bronchi. “The bronchi are located at the end of the trachea as the left or right bronchi. The bronchi branch throughout the lungs eventually forming thin-walled air sacs or bubbles, known as the alveoli ( Respiratory System, 2017).” “In the alveoli gas exchange takes place between the air and blood. Covering each alveolus is a network of blood vessel called capillaries, which are small
