'Vascular system’ app provides an in-depth and exclusive tour of the human body exploring the highways of life - the blood vessels. These blood vessels include the arteries, the veins and the capillaries. These blood vessels are the conduits for transportation of the vital body fluid - the blood. 'Vascular system’ app explains in detail about the arterial system, the venous system and the capillary network. It covers the details of the different arteries, different veins and their structural anatomy. The 'Vascular system’ app also explains the anatomy of the region where the finer branches of arteries - the arterioles transit into capillaries and the capillaries join to form the venules which then combine to form the veins. Let us explore the offerings of the 'Vascular system’ app. The user gets to interact with the 3D models of the vascular system comprising the arterial and venous systems. The user can explore the 3D models through the ‘rotate’, ‘zoom in’ and ‘zoom out’ options. The 3D models in the 'Vascular system’ app come with the desirable feature of ‘labels’. The labeling part is very important from the perspective of understanding anatomy of the systems. 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 'Vascular system’ app equips the user to attempt the diagrammatic questions asked in the exams. 'Vascular system’ app consists of the labeling part of the arteries and veins of the body. The app also provides details of the parts of the capillary network. Also the structural composition of the arteries , veins and capillaries is dealt with in the 'Vascular system’ app. The app 'Vascular system’ app also offers the Apple’s Augmented Reality (ARKit) feature that provides the user with an immersive and engaging experience of blending virtual organ systems with the real world. The user can place the virtual arterial and venous system on any surface and can reorient his/her device to explore these systems from different angles. The exploration involves the interactivity with these systems for the ultimate understanding of their structure and function.
