‘Respiratory system’ app provides an in-depth and informative tour of the human respiratory system exploring all the amazing organs that keep our body’s breathing apparatus functioning at full swing. ‘Respiratory system’ app explains the different vital organs of the respiratory system. The explanation includes the anatomy and physiology of these organs. The organs include the sac-like lungs which are the main respiratory organs. The other assisting respiratory organs include the muscular diaphragm, the tubular trachea with its branches - bronchi and bronchioles. The terminal part of bronchioles consists of a structure that looks like a bunch of grapes. These structures are the ‘alveoli’. The ‘Human respiratory apparatus’ app explains all these organs in vivid details. Let us explore the offerings of the ‘Respiratory system’ app. The user gets to interact with the 3D model of the respiratory system. The user can explore the 3D models through the ‘rotate’, ‘zoom in’ and ‘zoom out’ options. The 3D models in the ‘Human respiratory apparatus’ app come with the desirable feature of ‘labels’. The labeling part is very important from the perspective of understanding the anatomy of the human respiratory system. Tapping the labels on the model which displays the name of the part gives the user the understanding of the name and structure and function of the respective part. The labeling part of the ‘Respiratory system’ app equips the user to attempt the diagrammatic questions asked in the exams. ‘Respiratory system’ app stands out as it not only offers the understanding of the anatomy of human respiratory system but also how the organs of the respiratory system work tirelessly to allow the processes of respiration to happen. The ‘Respiratory system’ app explains the physiology of breathing involving ‘inhalation’ and ‘exhalation’ through interactivity. The user can simulate the steps of breathing and thus can increase his/her comprehension of the system. Also the user can simulate the process of gaseous exchange occurring in the alveoli. This hands-on experience increases the understanding of the user to manifolds. The app ‘Respiratory system’ app also offers the Apple’s Augmented Reality (ARKit) feature that provides the user with an immersive and engaging experience of blending virtual respiratory system with the real world. The user can place the virtual respiratory system on any surface and can reorient his/her device to explore the system from different angles. The exploration involves the interactivity with the respiratory organs for the ultimate understanding of their structure and function.
