homeostasis
(same state) maintenance of internal parameters within a range that is compatible for life TERM 2
animal form and function
DEFINITION 2
- are correlated at all levels of function 2. size and shape affect the way an animal interacts with its environment. 3. Many different animal body plans have evolved and are determined by the genome. TERM 3
Genome
DEFINITION 3 genome is halpoid set of chromosomes in each cell of a micro-organism TERM 4
body size and surface area
DEFINITION 4 an animals size and shape directly affect how it exchanges energy and materials with its surroundings TERM 5
The exchange
DEFINITION 5 exchange occurs as substances dissolved in the aqueous medium diffuse and are transported across the cell's plasma membraneex: a single celled Protist living in water has sufficient surface area of plasma membrane to service its entire volume of cytoplasm
surface area
the surface area of large complex forms is large TERM 7
Surface area in multicellular
DEFINITION 7 multicellular organisms with a sac body plan have body walls that are only two cells thick, facilitating diffusion of materials TERM 8
surface are in more complex
DEFINITION 8 more complex organisms have highly folded internal surfaces for exchanging materials TERM 9
First type of tissue
DEFINITION 9
- covers body surface and lines organs, cavities and ducts - comprises glands -always a-vascular TERM 10
second type of tissue
DEFINITION 10 -protects supports and binds organs-fat storage-immunity- transport
exocrine glands
secrete products into ducts that empty onto the surface of the epithelium ex: mucus, sweat, oil, ear wax, saliva, and digestive enzymes TERM 17
connective tissues
DEFINITION 17 contains sparsely packed cells scattered throughout an extracellular matrix TERM 18
connective matrix
DEFINITION 18 consists of fibers in a liquid jelly like or solid foundationex: bone, blood, adipose, cartilage, tendons and ligaments TERM 19
3 types
DEFINITION 19 types of connective tissues1.collagenous 2.elastic3.reticular TERM 20
collagenous fibers
DEFINITION 20 provide strength and flexibility
elastic fibers
stretch and snap back to their original length TERM 22
reticular fibers
DEFINITION 22 join connective tissue to adjacent tissue TERM 23
loose connective tissue
DEFINITION 23 binds epithelial to underlying tissues and holds organs in place TERM 24
cartilage
DEFINITION 24 is a strong and flexible support material TERM 25
fibrous connective tissue
DEFINITION 25 is found in tendons, which attach muscles to bones, and ligaments, which connect bones to joints
cardiac muscle
is responsible for contractions of the heart TERM 32
neurons
DEFINITION 32 also known as nerve cells that transmit nerve impulses. (in nervous tissue) TERM 33
glial cells
DEFINITION 33 (glia) helps nourish, insulate, and replenish neurons TERM 34
feedback
loops
DEFINITION 34 feedback control loops maintain the internal environment by regulating or conforming to the external environment TERM 35
regulator
DEFINITION 35 uses internal control mechanisms to moderate internal change in the face of external, environmental fluctuation
conformer
allows its internal conditions to vary with certain external changes TERM 37
homeostasis
DEFINITION 37 organisms uses homeostasis to maintain a "steady state" or internal balance regardless of external environments.in animals, pH ion concentration, glucose levels and many other variables are maintained within a narrow range through physiological mechanisms. TERM 38
negative
feedback
DEFINITION 38 feedback stabilizes systemexample: rising glucose levels and decreasing glucose levels TERM 39
positive
feedback
DEFINITION 39 loops occur in animals, but do not usually contribute to homeostasis TERM 40
thermoregulation
DEFINITION 40 is the process where animals maintain internal temperature within a tolerable range
metabolic
rate
is the amount of energy an animal uses in a unit of time.One way to measure it is to determine amount of oxygen consumed or carbon dioxide produced TERM 47
endotherms
DEFINITION 47 animals that maintain fairly constant body temperature ex: mammals and birds. all others are ectotherms
