|
Where does gas exchange occur in the body? (2 locations) |
1. Lungs (Alveoli) >>>>>>Oxygen>>>>>Capillaries << 2. Capillaries >>>>>>>Oxygen>>>>>>>>> Cells <<<< |
|
|
List the parts a molecule of oxygen would travel through from the nasal passage to an alveolus |
Nasal Passage> Pharynx> Larynx> Trachea> Bronchi> Bronchioles> Alveolus |
|
|
Compare the structures and locations of the esophagus and trachea |
Esophagus: smaller then the trachea, flexible, muscular tube, located behind the trachea Trachea: strong and wide tube, made of a number of cartilaginous rings, located in front of the esophagus |
|
|
Explain how inspiration occurs |
As the diaphragm muscle contracts, it moves downwards. The ribs move out and the chest cavity expands. A partial vacuum thus draws air into the lungs |
|
|
Explain how expiration occurs |
As the diaphragm muscle relaxes, it moves upwards. The ribs move down and the air is forced out of the lungs |
|
|
How do pressure differences aid in breathing and respiration? |
In low pressure air it is easier to breathe, high pressure is harder, so when you go from low to high pressure air, breathing becomes easier |
|
|
Explain how oxygen and carbon dioxide differ in how they are carried in the blood |
Oxygen is carried hemoglobin in red blood cells Carbon dioxide attaches to hemoglobin to be carried |
|
|
Identify some common ailments of the respiratory system |
Influenza, Tuberculosis, Pneumonia, Cystic Fibrosis (CF), Asthma, Chronic Obstructive Pulmonary Disease (COPD) |
|
|
Describe how the digestive, circulatory, and respiratory systems are all interconnected and supportive to eachother |
Digestive System: Provides the diaphragm with nutrients to facilitate breathing; breaks down starch into glucose which is mixed with oxygen to produce carbon dioxide, water, and energy; provides the heart with nutrients to keep the heart beating Circulatory System: moves oxygen and glucose around the body so it can be used by cells; moves waste so it can disposed of by the body Respiratory System: provides oxygen to the digestive system so it can digest food; removes carbon dioxide and water that the cells/heart produce as waste; provides the oxygen that red blood cells carry around the body |
