Respiration Flashcards
What is the purpose of respiration?
To get oxygen to body cells, and get rid of carbon dioxide.
Why do cells need oxygen?
Because it provides energy for them.
What does the Eustachian tube do? Where is it located?
The Eustachian tube keeps balance between pressure on the two sides of the middle ear. It is located between the mouth and the middle of the ear.
What two things may happen if you sneeze too roughly?
The eardrums may be damaged, and germs may travel to the ear.
The villi : Small Intestine, as the alveoli : what? Why are they both important?
Air sacs. They are important because they both absorbs nutrients, to give to body cells.
List in order the parts of the body which air travels through until it reaches the air sacs.
Mouth/Nose, Throat, Trachea, Bronchi, Bronchioles, Air Sacs.
What are the roles in respiration for the cilia, diaphragm and muscles between ribs, epiglottis, and air sac?
Cilia: Take unknown particles from air and traps them. Diaphragm and Muscles between Ribs: To expand when taking in air, and come in when air is let out. Epiglottis: to allow air into the trachea. Air Sac: To allow oxygen and CO2 diffuse in and out of the air sacs.
What gas diffuses into and out of the blood in the body? What gas diffuse into and out of the blood at the lungs?
Oxygen diffuses out, and CO2 diffuses in. Oxygen diffuses in, and CO2 diffuses out.
How do the respiratory and circulatory systems work together?
Oxygen enters air sacs, which diffuses into the bloodstream, and is sent to the body. CO2 then enters the bloodstream, diffuses into the air sacs, and is sent out the mouth.
What disease is caused by the decreased surface area of the lungs? How does this make it harder to breathe for some people?
Emphysema. Less surface area for oxygen and CO2 to diffuse in and out of.
What are two other diseases caused by smoking?
Lung Cancer, Bronchitis, Heart Disease.
Which of the five main concepts are used in these actions and products of the body? The stomach has several muscle layers which allow it to churn. The small intestines are lined with villi for absorption. Balancing Energy-In and Energy-Out. The digestive and circulatory systems work together. Drinking enough water.
- Structure to Function.
- Surface Area.
- Homeostasis.
- Systems.
- Homeostasis.
What are some ways that pollution affects us? List four or more.
Leukemia, Reproductive Abnormalities, Nervous System Abnormalities, Bronchitis, Lung Cancer, and Emphysema.
Why is it important to put data in tables or graphs?
So that the data and relationships are easier to show between the different trials of the experiment.
