Layer based (simple, stratified, pseudostratified)

Question 3

Answer 5

Smooth, striated, cardiac

Question 6

Organs

Answer 6

Organ that contains all 4 tissues that work together

Question 8

Integrator

Answer 8

Control center, usually brain

Can activate a second mechanism (effector)

Evaluates conditions detected by receptor

Question 9

Ectotherms

Answer 9

Obtain body heat from environment

Includes invertebrates, amphibians, reptiles, fish

Also called poikilotherms, cold blooded

Question 10

Endotherms

Answer 10

Generate own body heat

Also called homeotherms, warm blooded

Question 11

Cooling by Evaporation

Answer 11

Sweat (liquid) evaporates (gas)

Endergonic reaction (requires heat)

Includes evaporation out of the respiratory system (like when dogs pant)

Question 12

Warming by Metabolism

Answer 12

Metabolic activities generate heat

i..e Contracting muscles (why we shiver when cold)

Question 13

Adjusting Surface Area

Answer 13

Extremities add surface area to body

Body can adjust amount of blood flow to certain areas of the body to warm or cool us using vasodilation or vasoconstriction

i..e Reduced blood flow to hands when its cold

Question 14

Answer 14

In hot climates, increased blood flow to large ears, allowing their body to remain cool
