The job of the respiratory system is..
What is ventilation (bring air in/out) and respiration (gas exchange)

What is it called when your body works to maintain a steady internal environment?
What is homeostasis.

What are the two types of digestion that take place in the digestive system?
What is chemical and mechanical digestion.

True or false, the cardiovascular system helps deliver nutrients to cells and take away waste.
What is true.
200
The movement of gases between cells is known as..
What is respiration
200
Which body system consists of the brain and spinal cord?
What is the nervous system.
200
Which organs have failed if your body is unable to filter waste out of the blood?
What is the kidneys.
300
What is the role of the pancreas in digestion?
What is producing digestive enzymes to help chemically digest food in the small intestine.
300
What is the name of the structure that prevents blood from flowing backwards?
What is a valve.
300
List the names of the organs of respiration in the order that air entering the body passes through them.
What is nose/mouth, pharynx, larynx, trachea, bronchi, alveoli
300
How do the skeletal and muscular systems work together? What do they do?
What is the skeleton and muscles allow for support movement. Muscles attach to the skeleton. When the muscles lengthen or shorten, they move the skeleton.
300
A blockage to your pulmonary artery is likely to result in...
What is an inability to send blood to the lungs to pick up oxygen and remove carbon dioxide.
400
How would removing the gallbladder affect your ability to digest food?
What is you would have a harder time breaking down fats.
400
Why might the left side of the heart be bigger than the right side?
What is the left side of the heart pumps blood to the body, which means it has to push harder to push the blood farther.
400
Damage to the alveoli is most likely to result in...
What is having trouble respiring (exchanging gases between the air and the blood).
400
How does the endocrine system help regulate blood sugar?
What is the pancreas senses changes in blood glucose (sugar) levels and releases insulin to help target cells absorb the extra glucose for storage.
400
Explain how a feedback loop works.
What is a receptor receives the stimulus and sends the information to the control center, which processes the signal and sends an appropriate response to organs throughout the body.
500
How would removing part of the small intestine affect your ability to get energy from food?
What is there is less surface area for absorption of nutrients and therefore fewer nutrients go into the bloodstream for circulation/distribution to cells.
500
Predict what might happen if you had a blockage in your vena cava.
What is you would not be able to get CO2 filled blood back to the heart to send to the lungs to remove CO2 and pick up O2.
500
When you smoke a cigarette, it disables the cilia in the airways. What sort of problems is this likely to cause?
What is cilia help filter the air we breathe and remove mucus from airways. Without the cilia you have trouble filtering out dirt and clearing mucus, which can cause infection and make breathing harder.
500
Removal of this organ will result in trouble chemically digesting food AND an inability to regulate blood sugar.
What is the pancreas!
500
How do feedback loops help maintain homeostasis?
What is feedback loops make sure that certain variables stay within an acceptable range by collecting information and sending important signals to the body to respond if the numbers fall outside of that range.
