Simulator that calculates the amount of drug to add to the water when using a flow dispenser. Their morphology varies from rounded to cubic, with few microvilli on their free surface. We must never forget that the alveolus, the place where the respiratory exchange takes place, has contact with the exterior, so the integrity of the mucociliary apparatus and the functionality of the macrophages is fundamental to maintain the homeostasis of the respiratory function. In the hind limb, the pig has the same muscles as humans in the major thigh muscle groups: quadriceps femoris and the hamstrings; see p. 35 of the FPDG (Fetal Pig Dissection Guide).

Viruses such as porcine reproductive and respiratory syndrome (PRRSV) whose main cell targets are alveolar macrophages (Figure 3), alter their basic functions (phagocytosis, antigen presentation and cytokine production) and cause them to eventually die by necrosis and/or apoptosis, which modulates the immune response, producing a delay in the emergence of an effective adaptive response, thus favoring the emergence of secondary infections.
