What are protostomes?

Organisms that have radial cleavage and develop an anus from the blastopore, e.g., echinoderms and vertebrates

What are deuterostomes?

System which transports oxygen and nutrients to cells and carbon dioxide and wastes away from cells

What is the circulatory system?

System responsible for bringing in oxygen and ridding the body of waste carbon dioxide

What is the respiratory system?

Rids animals of wastes, helps conserve water, and filters wastes from the blood

System responsible for breaking food stuffs into smaller, absorbable nutrients

What is the digestive system?

System responsible for producing gametes for perpetuation of the species

Having an anterior end with sensory organs concentrated there

What is cephalization?

The hollow ball of cells that forms after fertilization
