The mammary glands are paired structures that contain glandular tissue and a variable amount of fat. The correct sequence of tissues involved in the synthesis and flow of milk is:

• A
  Mammary lobes $\rightarrow$ Mammary alveoli $\rightarrow$ Mammary ampulla $\rightarrow$ Mammary duct $\rightarrow$ Lactiferous duct
• B
  Mammary lobes $\rightarrow$ Mammary alveoli $\rightarrow$ Mammary duct $\rightarrow$ Mammary ampulla $\rightarrow$ Lactiferous duct
• C
  Mammary lobes $\rightarrow$ Mammary alveoli $\rightarrow$ Lactiferous duct $\rightarrow$ Mammary ampulla $\rightarrow$ Mammary duct
• D
  Mammary alveoli $\rightarrow$ Mammary lobes $\rightarrow$ Lactiferous duct $\rightarrow$ Mammary duct
