Yes, flies do have a heart.
Fly Heart Anatomy
The fly's heart, according to research, is a simple, yet effective organ. Here's a breakdown of its key features:
- Location: The heart is located along the dorsal side of the abdomen.
- Structure: It is a roughly 1 mm long muscular tube.
- Valves: The heart contains a number of intake valves that regulate blood flow.
- Aorta: At the front end of the abdomen, near the fly's "waist," the heart narrows into the aorta. The aorta runs through the thorax and opens into the head. This distributes hemolymph (insect blood) throughout the fly's body.
