Question

Definition Definition Organ system that helps in the digestion of food by mechanical and biochemical processes. The digestive system breaks down food into simpler components that enable the body to then absorb or transport nutrients. The human digestive system includes the gastrointestinal tract or alimentary canal and the associate glands. The organs of the gastrointestinal tract include the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. The associated glands include salivary glands, liver, gallbladder, and pancreas.

Expert Solution & Answer

Explanation of Solution

Arthropods are bilaterally symmetrical, triploblastic organisms with an organ system level of body plan. They have a complete digestive tube. Presence of a segmented body, a hard exoskeleton composed of chitin and protein, and the paired jointed appendages are the characteristic features of arthropods. The appendages are modified for various functions such as swimming paddles, walking legs, mouthparts, and sensory organs.

The nervous system consists of a brain and ventral nerve cord with ganglia. Some arthropods such as insects and many crustaceans have compound eyes composed of many light-sensitive units called ommatidia. Arthropods have an open circulatory system and a dorsal, tubular heart. Arthropods have gills, tracheae, or book lungs for breathing. They have a complete digestive system. Different classes of arthropods have various excretory structures. For example, two or more malpighian tubules receive metabolic wastes from the blood in insects and serve as structures of excretion.
