In addition to these, Hemal models in countless shows throughout the year.

The body cavity contains the circulatory or hemal system.

The neural and hemal spines tend to be simple and slender.

Between the second and third caudal vertebrae, separate bones called hemal arches are present.

Sea urchins possess both a water vascular system and a hemal system, the latter containing blood.

Oxygen is transported through the body via the hemal system, a series of sinuses and vessels distinct from the water vascular system.

This fluid contains phagocytic coelomocytes, which move through the vascular and hemal systems.

Hemal Jhaveri of TVSquad described the episode as "excellent".

Oxygen dissolved in the water is distributed through the body mainly by the fluid in the main body cavity; the hemal system may also play a minor role.

An arch extending from the top of the centrum is called a neural arch, while the hemal arch or chevron is found underneath the centrum in the caudal (tail) vertebrae of fish.

The internal anatomy consists of a complete gut, a nervous system with two visceral nerve cords and two serving the foot, and a hemal system composed of the heart, vessels, and unlined sinuses that make the hemocoel.

Bryozoan's tentacles bear cells with multiple cilia, while the corresponding cells of phoronids', brachiopods' and pterobranchs' lophophores have one cilium per cell; and bryozoan tentacles have no hemal canal ("blood vessel"), which those of the other three phyla have.

Parts eviscerated include the gut, associated heamal vessels, tentacles, and introvert (the dexterous anterior extensible portion of the body wall).
