Chpt. 31, 32 Flashcards
(24 cards)
Homeothermic
Organisms that are able to survive with internal body temperature
Narrow range/ same temperature
Define organ
Structures that preform complex functions
What are the 3 major parts of the circulatory system?
1) A pump- the heart
2) A liquid- the blood
3) A system of tubes- blood vessels
Define organ systems
2 or more interacting organs that function in a coordinating manner
What is a single loop circulatory system?
( name an example)
One trip throughout the body
Heart—> body
Ex: fish
Proximal
Closer to the attachment of the appendage of the body
Lateral
Farther away from the midline
Dorsal
(Back) of the animal
Medial
Closer to the midline of the limb, trunk, or head
What is the order of the hierarchy of structures?
Cells—> tissue—> organs—> organ systems
Define tissue
Cells that preform functions
Distal
Further away from the attachment of the appendage of the body
Cranial
Closer to the head of the animal
Endotherms generate most of their heat through…?
Metabolic reactions
What is a double- loop circulatory system?
(Name an example)
2 trips throughout the body
Heart—>body—> lungs
(Goes to lungs to release the carbon dioxide from the blood and gets “ clean”)
Caudal
Closer to the tail
Ventral
(Belly) of the animal
Every vertebrate has a ….?
Closed circulatory system
What is C6 H12 O2 ?
Glucose
Poikilothermic
Organisms that can survive with internal body temperature
Wide range/ varying range
Define cells
Unit of all living things
Homeostatic
Regulates conditions such as glucose
Ectoderms
(advantages / disadvantages
Adv: uses less energy
More energy for growth
Disadv: vulnerable to predators
Lower reaction to stimuli
Endotherms
Advantages / disadvantages
Adv: regulate body temperature in different environments
Less susceptible to change in the environment
Disadv: need a lot of energy maintain body temperature
Less energy for growth and reproduction
