Structure | Function |
Esophagus | Passageway between mouth and crop |
Crop | Highly extensible, anterior portion of the digestive tract; serves as a storage compartment for food |
Stomach | Chamber that receives semi-digested food from the crop and secretes enzymes for chemical digestion |
Gastric ceca | Lobed, accessory digestive areas located at the juncture between the crop and stomach that facilitate chemical digestion |
Intestine | Shortened tube passing through the abdomen in which nutients are absorbed into the bloodstream |
Rectum | Specialized swelling of the posterior portion of the digestive tract for efficient water reabsorption and conservation |
Anus | Terminal portion of the digestive tract; regulates egestion of undigested food from the body |
Ovaries | Site of ova production and maturation; fertilization is internal and fertilized eggs are deposited in the soil |
Testes | Site of sperm production |
Heart | Specialized muscular swellings of the dorsal blood vessel containing ostia (holes) to allow passive uptake of hemolymph that is delivered to the body tissues through arteries; veins do not exist in this open system |
Malpighian tubules | Stringy, fibrous excretory organs scattered along the margins of the stomach and intestine; release metabolic waste into the digestive tract so excess water may be reabsorbed by the intestine and rectum and conserved in the body |
Brain | Enlarged conglomeration of nervous tissue located in the head; processes sensory information and coordinates major bodily functions |
Ventral nerve cord | Long, whitish "cord" located along the ventral surface of the body; contains large swellings of ganglia that handle some nervous coordination without intervention by the brain |
