m Flashcards
- Vertebrates
Vertebrates comprise all species of animals within the subphylum Vertebrata, including all mammals, birds, reptiles, amphibians, and fish. Vertebrates represent the overwhelming majority of the phylum Chordata, with currently about 69,963 species described.
- Invertebrates
Invertebrates are animals that neither possess nor develop a vertebral column, derived from the notochord. This includes all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelid, and cnidarians.
- Consumer
A consumer is a person or a group who intends to order, orders, or uses purchased goods, products, or services primarily for personal, social, family, household and similar needs, not directly related to entrepreneurial or business activities
- Ganglion
The cause of ganglion cysts is unknown.
A ganglion cyst is round, small, and usually painless. Although rare, it can be painful if it presses a nerve. In a few cases, the cyst can interfere with joint movement.
A ganglion cyst often clears on its own. If troublesome, it can be drained or removed.
- Gut
The gastrointestinal tract is the tract or passageway of the digestive system that leads from the mouth to the anus. The GI tract contains all the major organs of the digestive system, in humans and other animals, including the esophagus, stomach, and intestines.
- Coelom
the body cavity in metazoans, located between the intestinal canal and the body wall.
- Bilateral Symmetry
the property of being divisible into symmetrical halves on either side of a unique plane.
- Radial Symmetry
symmetry around a central axis, as in a starfish or a tulip flower.
- Asymmetry
Asymmetry is the first novel by American author Lisa Halliday, published in February 2018 by Simon & Schuster. Wikipedia
- Sponges
Sponges, the members of the phylum Porifera, are a basal animal clade as a sister of the Diploblasts. They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells.
- Cnidarians
Cnidaria is a phylum under kingdom Animalia containing over 11,000 species of aquatic animals found both in freshwater and marine environments, predominantly the latter. Their distinguishing feature is cnidocytes, specialized cells that they use mainly for capturing prey.
- Flatworms
The flatworms, flat worms, Platyhelminthes, or platyhelminths are a phylum of relatively simple bilaterian, unsegmented, soft-bodied invertebrates.
- Roundworms
The nematodes or roundworms constitute the phylum Nematoda, with plant-parasitic nematodes also known as eelworms. They are a diverse animal phylum inhabiting a broad range of environments
- Mollusks
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda. The members are known as molluscs or mollusks. Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species.
- Open circulatory system
Open circulatory systems are systems where blood, rather than being sealed tight in arteries and veins, suffuses the body and may be directly open to the environment at places such as the digestive tract. Open circulatory systems use hemolymph instead of blood.
- Closed circulatory syste
In a closed circulatory system, blood is contained inside blood vessels, circulating unidirectionally (in one direction) from the heart around the systemic circulatory route, then returning to the heart again. … Most vertebrates and some invertebrates, such as this annelid earthworm, have a closed circulatory system.
- Annelid worms
The annelids, also known as the ringed worms or segmented worms, are a large phylum, with over 22,000 extant species including ragworms, earthworms, and leeches.
- Exoskeleton
An exoskeleton is the external skeleton that supports and protects an animal’s body, in contrast to the internal skeleton of, for example, a human. In usage, some of the larger kinds of exoskeletons are known as “shells
- Compound eye
A compound eye is a visual organ found in arthropods such as insects and crustaceans. It may consist of thousands of ommatidia, which are tiny independent photoreception units that consist of a cornea, lens, and photoreceptor cells which distinguish brightness and color.
- Antenna
In radio engineering, an antenna or aerial is the interface between radio waves propagating through space and electric currents moving in metal conductors, used with a transmitter or receiver.
- Metamorphosis
Metamorphosis is an allegorical novella written by Franz Kafka which was first published in 1915.
- Endoskeleton
An endoskeleton is an internal support structure of an animal, composed of mineralized tissue.
- Water vascular system
The water vascular system is a hydraulic system used by echinoderms, such as sea stars and sea urchins, for locomotion, food and waste transportation, and respiration. The system is composed of canals connecting numerous tube feet.
