WebGas exchange occurs in the lungs where oxygen enters from the air and diffuses into the blood stream and carbon dioxide in moves the opposite direction. Oxygen is needed for respiration by the body, for example for aerobic respiration in the muscles, which produces carbon dioxide as a waste product.Lungs have a large surface area to volume ... WebInstead, their cells exchange gases by diffusion directly with the environment. They have an incomplete digestive system. Flatworms reflect several major evolutionary advances in invertebrates. They have three embryonic cell layers, including mesoderm. The mesoderm layer allows them to develop organ systems.

Webfilled with water), gas exchange, and the excretion of metabolic wastes. The epidermis of a cnidarian contains contractile cells that will allow for movement. A simple nervous system, called a nerve net, coordinates these movements. These adaptations allow for a more active lifestyle than the sponges previously examined; cnidarians are predators! WebNov 1, 2024 · Depending on its size and habitat, an animal may employ direct diffusion, gills, lungs, or other respiratory passages for gas exchange. In higher order animals, such as mammals, the respiratory and circulatory systems work together. club car precedent headlight switch

Digestion Planarians are carnivores and obtain their food by predation or scavenging. The muscular pharynx extends through the mouth to pick up food and then withdraws into the body. The pharynx leads to a branched digestive tract. club car precedent horn kit

"WebFlatworms have an excretory system with a network of tubules attached to flame cells, whose cilia beat to direct waste fluids concentrated in the tubules out of the body through excretory pores. The system is responsible for the regulation of dissolved salts and the excretion of nitrogenous wastes. " - Flatworm gas exchange adaptations
