Gill pores

Glomerulus
Part of the vertebrate kidney consisting of capillaries surrounded by the renal capsule; also a network of blood sinuses forming a spongy tissue in hemichordates and assumed to have an excretory function.
Heart vesicle
.
Mesocoel
The middle of three coelomic spaces found in the tripartate body plan characteristic of the deuterostome lineage of animals. The other coelomic compartments are the protocoel and metacoel.
Metacoel
The last of three coelomic spaces found in the tripartate body plan characteristic of the deuterostome lineage of animals. The other coelomic compartments are the protocoel and mesocoel.
Neural plate
.
Pharyngeal gill slits
.
Preoral ciliary organ
.
Proboscis
Tubular feeding structure that extends from an animal. In many invertebrates, it is eversible and extends from the body to permit feeding.
Proboscis pore
.
Protocoel
The first of three coelomic spaces found in the tripartate body plan characteristic of the deuterostome lineage of animals. The other coelomic compartments are the mesocoel and metacoel.
Stomochord proboscis complex
.
Suspension feeding
Feeding by removing particulate food suspended in the surrounding water.
Tripartite coelem
Characteristic of the deuterostome line of animals. The coelom forms with three separate compartments referred to as the protocoel, mesocoel, and metacoel.
Trunk
In animals with more than one body region, or tagmata, the trunk, or torso, is the part of the body behind the head, not including the limbs, or it’s the combined thoracic and abdominal tagma.
