Question | Answer |
---|---|
Vertebrae | Segments of bone or some other hard substance that are arranged into a backbone |
Notochord | Rod of tough, flexible material that runs the length of a creature's body, providing the majority of its support |
Endoskeleton | Skeleton on the inside of a creature's body, typically composed of bone or cartilage |
Bone marrow | Soft tissue inside the bone that produces blood cells |
Axial skeleton | Portion of the skeleton that supports and protects the head, neck, and trunk |
Appendicular skeleton | Portion of the skeleton that attaches to the axial skeleton and has the limbs (appendages) attached to it |
Closed circulatory system | Circulatory system in which the oxygen-carrying blood cells never leave the blood vessels |
Arteries | Blood vessels that carry blood away from the heart |
Capillaries | Tiny, thin-walled blood vessels that allow the exchange of gases and nutrients between the blood and the cells of the body |
Veins | Blood vessels that carry blood back to the heart |
Olfactory lobes | Lobes of the brain that receive signals from the receptors in the nose |
Cerebrum | Lobes of the brain that integrate sensory information and coordinate the creature's response to that information |
Medulla oblongata | Brain lobes that coordinate vital functions, such as in the circulatory and respiratory systems, and transport signals from the brain to the spinal cord |
Internal fertilization | Process by which the male places sperm inside the female's body, where the eggs are fertilized |
External fertilization | Process by which the female lays eggs and the male fertilizes them once they are outside of the female |
Oviparous development | Development that occurs in an egg that is hatched outside the female's body |
Ovoviviparous | Development that occurs in an egg that is hatched inside the female's body |
Viviparous | Development that occurs inside the female, allowing the offspring to gain nutrients and vital substances from the mother through a placenta |
Anadromous | Life cycle in which creatures are hatched in fresh water, migrate to salt water as adults, and go back to fresh water in order to reproduce |
Bile | Mixture of salts and phospholipids that aids in the breakdown of fat |
Atrium | Heart chamber that receives blood |
Ventricle | Heart chamber from which blood is pumped out |
Ectothermic | Lacking an internal mechanism for regulating body heat |
Hibernation | State of extremely low metabolism and respiration, accompanied by lower-than-normal body temperatures |
