what is anatomical dead space???
Answers
Dead space refers to the volume of air that enters the airways and lungs, but does not participate in gas exchange. In order to fill the alveoli to capacity, air must incidentally occupy spaces of the bronchioles, bronchi, and trachea, but these structures do not exhibit the thin epithelial-capillary interface for carbon dioxide and oxygen gas exchange. The volume of air taking up this space is called anatomic dead space. Physiologic dead space includes the dead space of the upper airways, but also accommodates for the dead space in alveoli that do not partake in gas-exchange for a number of reasons. Alveoli that fill with air but do not exchange gas to and from the capillaries contribute to physiologic dead space, which ideally would be very low, or almost zero.
