The correct route through which Ascaris lumbricoides passes to complete its life cycle after infecting a fresh host is as follows inside through contaminated food → Juvenile free IInd stage in human intestine → Hepatic portal vein → Liver → Heart → Lungs (pulmonary artery, lung capillaries and alveoli) → Wind pipes → Pharyn x→ Food pipe (Oesophagus or gullet) → Stomach → Intestine → Adult endoparasite → Fertilised eggs → Outside with host faecal matter.
