Answer:
Analogous structures
Explanation:
Analogous structures are similar structures that evolved independently in two living organisms to serve the same purpose.
Analogous structures are examples of convergent evolution, where two organisms separately have to solve the same evolutionary problem – such as staying hidden, flying, swimming, or conserving water – in similar ways. The result is similar body structures that developed independently.
In the case of analogous structures, the structures are not the same, and were not inherited from the same ancestor. But they look similar and serve a similar purpose.
For example, the wings of an insect, bird, and bat would all be analogous structures: they all evolved to allow flight, but they did not evolve at the same time, since insects, birds, and mammals all evolved the ability to fly at different times.

The nurse should first select an area to perform the hyphodermoclysis, outside of the elbow is usual but the back of the hand is fine too. Then the nurse must apply a tourniquet 10 cm before the selected area, so it blocks blood circulation. After feeling the vein stand out in the selected area, said area must be cleaned with an antiseptic solution. Then the nurse should introduce the needle connected to the catheter in the outstanding vein, following along the anatomy of the patient against the normal bloodstream direction, so the needle stays almost parallel to the vein while inserted. Finally the nurse must fix the needle to the arm using medical adhesive, and remove the tourniquet.
