Homologous structures have the internal structure, but different functions. For example the human arm, horse foreleg, bird wing, and whale flipper have similar internal skeletal structure, but different external structure because of their different functions. Analogous structures have similar external structure because of similar functions, but dissimilar internal structure. An example of analogous structures would be the wings of an insect and a bird.
the skeletal system and the circulatory
The structure of a bacteria cell that performs a similar function to the skin of a human is the cell wall.
The limbs of Species A have a similar structure to the limbs of Species B, but perform a different function.

how are parts of birds & fish similar in structure & function
Homologous organs have similar looking structure and similar origin but different functions . Whereas analogous is just the opposite analogous organs are those that have similar function but different origin and structure

the skeletal system and the circulatory
Homologous structures refer to structures on different species that are similar in function and their evolutionary origin. Analogous structures are similar in function but do not share a similarity in evolutionary origin.
The structure of a bacteria cell that performs a similar function to the skin of a human is the cell wall.
The limbs of Species A have a similar structure to the limbs of Species B, but perform a different function.
the alveoli
ear drum
Cell with similar structure and functions are grouped into tissues.
