Do Spiders Have Lungs?

Spiders (Araneae) are unique regarding their respiratory system: they are the only animal group that breathe simultaneously with lungs and tracheae

tracheae
Average configuration of the trachea was sagittal at the thoracic inlet and transverse supracarinally. Absolute tracheal cross sections of less than 120 mm2 in women and 190 mm2 in men and relative values of less than two-thirds compared with other levels should suggest an abnormality.
. Looking at the physiology of respiration the existence of tracheae plays an important role in spiders with a well-developed tracheal system.

Can you drown a spider?

“Flushed spiders will drown if they end up submerged in the sewer,” Jerome Rovner, a member of the American Arachnological Society, told Real Clear Science. “However, the drowning process for a spider can take an hour or more, as they have an extremely low metabolic rate and thus a very low rate of oxygen consumption.”

Do spiders have hearts and lungs?

Spiders have the same basic bodily systems as people, but they don't work in the same way and they're arranged differently in the body. The cephalothorax contains the brain, stomach, eyes and mouth, and the abdomen contains the heart, digestive tract, reproductive organs and lungs.
