used for gas exchange; the system for taking in oxygen and giving off carbon dioxide.
the organ system that filters blood and removes nitrogenous wastes from the body in the form of urea or uric acid. In humans, the two kidneys are the vital organs of blood filtration.
a system (including the thymus and bone marrow and lymphoid tissues) that protects the body from foreign substances and pathogenic organisms by producing the immune response
composed of skeletal, smooth, and cardiac muscle tissue and functions in movement of the body or of materials through the body, maintenance of posture, and heat production.
provides protection from infection & injury, prevents loss of water, helps regulate body temperature, & gets rid of waste
The bodily system that provides attachment for muscles, supports and protects the body, produces blood cells, and stores minerals.
provides the body with nutrients, water, and electrolytes essential for health. These organs serve to ingest, digest, and absorb food and eliminate the remains
System of organs and blood that brings nutrients and oxygen to cells and carries away wastes.
the body's "speedy", electrochemical communication system, consisting of all the nerve cells of the peripheral and central nervous systems
the body's "slow" chemical communication system; a set of glands that secrete hormones into the bloodstream
organs and tissues involved in the production and maturation of gametes and in their union and subsequent development as offspring
sessile animals with porous bodies that lack true tissues; suspension feeders, trap particles that pass through the interal channels of their bodies; Sponges
these animals have radial symmetry and a gastrovascular cavity with a single opening and tentacles to capture prey; nerve net but no brain; Corals, Jellies, and Hydras
these animals have bilateral symmetry; acoelemates with a gastrovascular cavitity having one opening; has a brain (central nervous system); Flatworms (tapeworms, planarians, flukes)
these animals are pseudocoloemates with jaws, crowns of cilia, and complete digestive tracts (separate mouth and anus); reproduce by parthenogenesis; Rotifers
these animals have a muscular foot, a visceral mass (internal organs), and a mantle (tissue or shell over body); Gastropods (snails, slugs), Bivalves (clams, oysters), Cephalopods (squids, octopuses)
these animals are segmented worms with a complete digestive tract and a closed circulatory system; Earthworms, Leeches
these animals are non-segmented pseudocoelomates and covered by tough cuticles which are periodically shed; Roundworms
these animals are segmented coelomates with exoskeletons and jointed appendages; Crustaceans (crabs, lobsters, shrimp), Insecta (insects), Arachnida (spiders, scorpions), Diplopoda (millipedes), Chilopoda (centipedes)
these animals have a water vascular systems (for movement, feeding, and gas exchange) and secondary radial anatomy (not radiate animals); Sea stars, Sand dollars
these animals are coelemates with a notochord; Vertebrates (Fish, Amphibians, Reptiles, Birds, Mammals)
