Being the most diverse kingdom in appearance with each phylum having its own typical body plan.
What is the Animal Kingdom best known for?
Heterotrophic, eukaryotic, and multicellular that lack cell walls.
Animals are what?
Invertebrates
95% of animals are what?
Vertebrates or chordates.
5% of animals are what?

Physiology
The study of animals is called…
Detritivore

Filter Feeders
Aquatic animals that strain food from water are called…
Parasite
Organisms that live in or on another organism are called…
Coelom
A fluid-filled body cavity which also acts as the the digestive system's main structure are called…
Take in O2 and give off CO2. Examples: Lungs, gills, through skin, diffusion.
What is a specific function of the respiratory system? Name a few examples of raspatory systems.
Larger Animals. It’s a system that circulates blood through the body. Open: blood is pumped by the heart directly into open body cavity. Closed: blood is contained in vessels (from the heart to the veins & arteries, and back).
What animals rely on Circulatory Systems? What is a circulatory system? What is the difference between an opened versus closed circulatory system?
Used for excreting unwanted items from your body.
What is the excretory system?
Ammonia
What is the primary waste product of the excretory system?
Response to stimuli.
What is the nervous system used for?
Cells that react to sound, light. Any external stimuli.
What are receptor cells?
Cells that are contained in the nervous system that make up the nervous system.
What are nerve cells?
This systems allows for most animals to be motile (to move). Muscles and bones work together to be able to move, which makes them unique.
What is the skeletal and muscle system? What makes them unique?
This system allows animals to reproduce. Most animals reproduce sexually to increase genetic diversity while some invertebrates can reproduce asexually to quickly increase their numbers.
What is the reproductive system? What is special about invertebrates?
An organism that has the reproductive organs of both sexes.
What is a Hermaphrodite?
The body plan of an animal, how its parts are arranged.
What is a body in animal evolution?
No pattern of symmetry in an organism.
What is asymmetry?
Symmetry that is based around a center point, like starfish.
What is radial symmetry?
Symmetry where both organisms have the same left and right side, but their internal organs aren’t the same (like humans).
What is bilateral symmetry>?
It’s the anterior concentration of sense organs, basically the organism has a head, usually with eyes, nose and other sense organs, plus a brain
What is Cephalization?
Segments of the body become specialized for specific purposes, like a bee.
What is Segmentation?
Backside of an organism.
What is the Dorsal side?
The abdominal or “belly side” of an organism.
What is the Ventral side?
The front part or “head” of organism with bilateral symmetry.
What is the Anterior side?
Opposite of the head or the “rear” of organism with bilateral symmetry.
What is the Posterior side?
It is a characteristic difference in animals that can differentiates the phyla.
What does the body cavity/coelom do?
A fertilized egg.
What is a zygote?
A hollow ball of cells
What is a blastula?
An opening that is formed as a result of the blastula folding inwards.
What is a Blastopore?
The mouth is formed from the blastopore.
What is the protostome?
The anus is formed from the blastopore.
What is the deuterostome?
It is determined by what is formed first (mouth or anus).
What determines if an organism is deuterostome or protostome?
An opening for solid waste removal from digestive tract.
What is the anus?
Endoderm, Mesoderm, Ectoderm.
What are the three germ layers called?
The innermost layer that develops into the lining of the digestive tract and respiratory tract.
What is the endoderm?
The middle layer that consists of muscle, circulatory, reproductive, and excretory systems.
What is the mesoderm?
The outermost layer consisting of sense organs, nerves, and the outer layer of skin.
What is the ectoderm?
