 | | Located in the thoracic (chest) cavity, the lungs of mammals have a spongy texture and are honeycombed with a moist epithelium that functions as the respiratory surface. | | | Also, when we inhale, the change of pressure in the thoracic (chest) cavity causes the venae cavae and other large veins near the heart to expand and fill with blood. | | | Muscle action changes the volume of the rib cage and the chest cavity, and the lungs follow suit. |

| | There is the development of a rudimentary brain, ventral nerve cord and excretory system made up of nephridia, nephrostomes, and nephridiopores. | | | The advantage, as we may note this week is that areas of the tract can become specialized to one way movement, where in two way movement, the tract must remain generalized. | | | This specialization along the gastrovascular cavity was possible because of a complete digestive tract with one way movement. |

| | Planaria 2 |
| | During feeding, the pharynx can be everted through the mouth and used to suck up fluids and soft tissue from captured prey. | | | Lacking a body cavity, the space between the gut and epidermis in these acoelomates is filled with a meshwork of mesodermal parenchyma as well as muscle fibers that run circularly, longitudinally and diagonally. | | | On the outside of the flatworm is a ciliated epidermis that contains many gland cells as well as dark-staining rod-shaped bodies called rhabdites that can discharge their contents to form a protective mucous layer around the body. |

| | One of the first types of digestive tracts was the gastrovascular cavity, currently found mostly in cnidarians (such as jellyfish, sea anemones). | | | From the gastrovascular cavity evolved the alimentary canal, which, in contrast to the gastrovascular cavity, was a one-way digestive tract that had two openings: the mouth, where food entered the digestive tract, and the anus, where wastes exited the digestive tract. | | | The first animals to have the alimentary canal were probably nematodes. |
