Loosely packed; not tightly. |
|
|
What is the stuff in between connective tissue cells? |
Matrix. |
|
|
What are the two components of matrix? |
1. Ground substance 2. Fibers |
|
|
What is ground substance? |
Watery, rubbery, unstructured material that fills in the space between connective tissue cells. |
|
|
What does ground substance contain? |
It contains proteins. |
|
|
What are the 4 kinds of ground substance and an example of each? |
1. Liquid- blood 2. Mucous- everything else 3. Cartilage- nose, ear 4. Hard- bone |
|
|
What is the purpose of fibers in the matrix? |
Fibers provide structure and support to the otherwise shapeless ground substance. |
|
|

|
Bioenergetics: input |
the energy in organic molecules |
|
|
Bioenergetics: output |
heat energy or energy of motion |
|
|
Bioenergetics: storage |
Growth; increase in biomass |
|
|
Endothermic: Regulator or conformer? Example |
Warm-blooded Regulator Mammals |
|
|
Exothermic: Regulator or conformer? Example |

|
|
Describe body size vs. metabolic rate |
As body mass increases, metabolic rate decreases exponetially. Mice have higher metabolic rates (and heart rates). Elephants have lower metabolic rates (and heart rates). |
