Question
What system does the muscular system work with to allow movement?
Page 2
Answer
Skeletal system
2
Question
What role do muscles play in maintaining body temperature?
Page 2
Answer
Generate enough heat to maintain a regular body temperature
3
Question
Where are nutrients initially broken down before delivery to body cells?
Page 2
Answer
In the digestive system
4
Question
What happens to nutrients after breakdown in the digestive system?
Page 2
Answer
They diffuse into the bloodstream
5
Question
How does the respiratory system contribute to delivery of substances to cells?
Page 2
Answer
It brings oxygen into the bloodstream
6
Question
What is the role of the circulatory system in nutrient and oxygen delivery?
Page 2
Answer
Circulates both nutrients and oxygen to the body cells
7
Question
How do the digestive, respiratory, and circulatory systems interact overall?
Page 2
Answer
Digestive breaks down nutrients into bloodstream, respiratory adds oxygen to blood, circulatory delivers both to cells
8
Question
What is the primary function of negative feedback mechanisms?
Page 2
Answer
Oppose the original stimulus to help return to a specific set point
9
Question
What is an example of a negative feedback mechanism?
Page 2
Answer
Thermoregulation
10
Question
When are positive feedback mechanisms primarily used?
Page 2
Answer
When there is danger to the organism or an immediate response is needed
11
Question
Name two examples of positive feedback mechanisms.
Page 2
Answer
Blood clotting and childbirth
12
Question
How does the lack of homeostasis affect chemical reactions in the body?
Page 2
Answer
Enzymes that control all chemical reactions would stop working
13
Question
What is the ultimate consequence if an organism fails to maintain homeostasis?
Page 2
Answer
Illness or even death
14
