---|---|
Body structure and protection | An exoskeleton made of chitin, a type of protein |
Respiration (breathing) and Circulation of oxygen | Spiracles (9 pairs in butterflies) are pores open to the air and tracheae (air tubes) carry air through the body. Gas exchange occurs at the tiny ends of the tracheae. A very inefficient system which limits the size of butterflies. Spiracles are located on the abdomen and thorax. |
Circulation of oxygen | Tracheae |
Circulation of blood (for nourishment, not oxygen) | A long, tubular heart (dorsal vessel) and hemocoel |
Digestive System | Proboscis, pharynx, foregut (the crop), midgut, hindgut, and anus |
Storage of food energy | Fat body |
Excretion of wastes | Malpighian tubules, long filaments which clean the blood and put the waste (urine) into the hindgut (rectum) |
Nervous system | Brain, ventral nerve cord, ganglia, peripheral nervous system (PNS) and visceral nerves. |
Sense of balance (especially while flying) | Johnston's organ (located at the base of the antennae). |
Reproduction | Ovaries (female) and testes (male) |
