Question

how the ants are living without heart ? which make the insects to live

Answer 1

They have heart, but it’s not like the human heart.

Ants, and insects in general, do not have a vein system or arteries. They have an open circular system, and their “heart” looks like an elongated tube.

Haemolymph is the ant equivalent of blood. It’s what transports nutrients, hormones and metabolic products. The ant’s heart is what circulates the haemolymph. The heart is more like an arteria and is surrounded by a few small muscles.
