The nervous system and the respiratory system are examples of organ systems
Cardiovascular and neurological
Homologous organs have similar embryonic origin and basic structure whereas Analogous organs have different embryonic origin and basic structure. Homologous organs may look different and may perform different function; e.g., forelimb of a man and flipper of a whale. Whereas Analogous organs look alike and perform same functions; e.g., Wings of birds and insects.
An example of a homologous structure that is greatly reduced in size is the pelvic bone in whales. These bones are remnants of hind limbs found in their land-dwelling ancestors, which have evolved to be much smaller and non-functional in whales due to their adaptation to an aquatic lifestyle.
An artificial organ is a man-made device that replicates the function of a natural organ in the body. Examples include artificial hearts, kidney dialysis machines, and cochlear implants. These devices are used to replace or support the function of failing or damaged organs in the body.
nephridia

by their homologous organ sturcture
Yes, the nails of a man and claw of a cat are homologous organs with similar structure but performs functions differently.

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
respiratory system
Cardiovascular and neurological
They are both. They are homologous because they are both examples of a vertebrate forelimb. They are analogous because they were adapted for flight independently of one another.
A homologous structure is an example of an organ or bone that appears in different animals, underlining anatomical commonalities demonstrating descent from a common ancestor.
