Water Vascular System

The lower lobe of the lungs primarily functions in the exchange of oxygen and carbon dioxide during respiration. It is responsible for oxygenating the blood and removing carbon dioxide to maintain proper gas exchange within the body.
The gastrozoid of an Obelia functions to capture and digest food for the colony. It is responsible for capturing prey using its tentacles and then passing the nutrients to other zooids within the colony through a shared network.
The chorion, a membrane surrounding the amniotic fluid, is responsible for gas exchange in the amniote egg. It allows for the diffusion of oxygen into the egg and the removal of carbon dioxide produced by the embryo. This process is crucial for the embryo's survival and development within the egg.

the Golgi Body is responsible for packaging substances for the cell.
it helps in: >movement; to coordinate locomotion, to grip on substrate to withstand pressure, and act as sense organs that response to variation within the environment. >feeding; it helps trap its prey, and with the help of the cilia it carries food to its mouth.

All echinoderms possess a unique water vascular system, which aids in locomotion, feeding, and respiration through the use of tube feet. Additionally, they exhibit radial symmetry, typically as pentamerous (five-part) symmetry in adults, allowing for a symmetrical arrangement of body parts around a central axis. These features are key to their classification and function within marine ecosystems.
A fierasfer and a sea cucumber are both echinoderms, meaning they belong to the same phylum, Echinodermata. They share similar characteristics, such as a radial symmetry and a water vascular system, which aids in locomotion and feeding. However, they belong to different classes within this phylum; fierasfers are part of the class Holothuroidea, while sea cucumbers are typically classified within the same class but refer to a specific subset of echinoderms. Overall, they are related through their evolutionary lineage but differ in their specific classifications and ecological roles.

The actual sites of gas exchange within the lungs are the alvioli.
Echinoderms and deuterostomes share a fundamental evolutionary relationship, as echinoderms are a subgroup within the deuterostome clade. This indicates that both groups, along with chordates and hemichordates, share a common ancestor, highlighting their evolutionary link. Deuterostomes are characterized by their embryonic development, where the anus forms before the mouth, a feature that distinguishes them from protostomes. This shared developmental pattern suggests that echinoderms and deuterostomes have diverged from a common lineage, influencing their anatomical and physiological traits.

The exchange of goods and services within a single country is called domestic trade.
