The Respiratory System The Respiratory System is made up of the nose, pharynx, larynx, bronchi, and lungs. The respiratory system is the system of the body that deals with breathing. When we breathe, the body takes in the oxygen that it needs and removes the carbon dioxide that it doesn’t need. Throughout the Respiratory System, enjoy beautiful forests, plains, and wonderful weather. Function: Provides gas exchange, intake of O 2 for delivery to body cells and elimination of CO 2 produced by body cells.
-Helps regulate blood pH – Contains receptors for smell -Filters inspired air -Produces vocal sound -Excretes small amount of water and hear Vital Capacity: The amount of air in a full breath Oxygen debt: The volume of oxygen required to metabolize and remove lactic acid and other metabolic products accumulated during a period of anaerobic muscle cell metabolism Anaerobic Respiration: form of respiration in which energy is released from chemical reactions in which free oxygen takes no part The Nose The nose is located on the face, the Great Escape ($6 admission), and includes the septal cartilage, lateral and alar nasal cartilage, and the nostrils (external nares).
Function: – Warming, moistening, and filtering of incoming air- Detecting smell stimuli- Modifying speech vibrations The Pharynx The pharynx is the portion of digestive tube between the mouth and esophagus. Function: Collects incoming air from the nose and passes it downward to the trachea. If you have lost any items throughout the day, check here before we pass it along to the Larynx Light Show center. The Larynx The larynx is the structure between pharynx and trachea. The larynx performs the Larynx Light Show every night, but remember your ear plugs, because some of the sounds are quite loud! Function: Here, the vocal cords are housed.
The Essay on Lymphatic System 2
1.What is the significance of a lower-than-normal hematocrit? What is the effect of a bacterial infection on the hematocrit? A lower than normal hematocrit indicates anemia, a condition in which the body does not have enough healthy red blood cells. Red blood cells provide oxygen to the body tissues. If you have a bacterial infection, your white blood cell count would increase because as the ...
The Bronchi The trachea divides into the two main bronchi, one for each lung. These, in turn, subdivide further into bronchioles. Take a walk on the Bronchi Brisk Path and enjoy endless paths in the beautiful Lung Forest. The Lungs The lungs are two organs of respiration. The Lung Forest is a beautiful place to relax or exercise.
The cilia provides great shade and even lessens the pollen build up the trees! Function: Bring air and blood into close contact so that oxygen can be added to and carbon dioxide removed from the blood. The Diaphragm The diaphragm is the muscle that controls the breathing process. As the diaphragm flattens it forces the chest to expand and air is sucked into the lungs. When the diaphragm relaxes, the chest collapses and the air in the lungs is forced out. The Ribs The ribs are bones supporting and protecting the chest cavity. They move to a limited degree, helping the lungs to expand and contract.
Alveoli and Capillaries Inside the lung, the tubes divide into smaller and smaller tubes called bronchioles. At the end of each of these tubes are small air sacs called alveoli. Capillaries, which are small blood vessels with thin walls, are wrapped around these alveoli. The walls are so thin and close to each other that the air easily seeps through. In this way, oxygen seeps through into the bloodstream and carbon dioxide, in the bloodstream, bleeds through into the alveoli, and is then removed from the body when we breathe out. How Breathing is controlled The body knows how to control the breathing rate by the amount of carbon dioxide in the arterial blood.
The Essay on Carbon Dioxide School Air Levels
Danger in the Air At North Intermediate School in Wilmington? Is there danger in the air at the North Intermediate School in Wilmington? Apparently carbon dioxide levels have been found to be above acceptable levels in some class rooms. According to a report dated Dec. 9, 1996, by ATC Associations, an independent consulting firm hired by the Town of Wilmington to conduct Indoor Air Quality and ...
For example, when you exercise, carbon dioxide levels increase which excite the respiratory centre. It strengthens the signal – stimulating the breathing. Responding to this stronger signal, the respiratory muscles increase both the speed and depth of breathing. This increased respiration rids the body of excess carbon dioxide and supplies the body with more oxygen, which is needed when you exercise. When the level of carbon dioxide in the arterial blood returns to normal levels, the respiratory center is no longer stimulated and breathing becomes quiet and relaxed. Carbon dioxide acts as a marker.
When carbon dioxide levels reach a certain point, the respiratory center in our brain sends a message to the muscles used for breathing to take in more air.
