Respiratory System: Period 7 Ethan, Katie, Sammy, Kylie
Function of the Respiratory System The purpose of the respiratory system is to take in oxygen and to distribute it to the rest of the body. The respiratory system also responsible for exhaling carbon dioxide.
The Main Organs Involved The main organisms involved in the respiratory system are the Trachea Bronchi Bronchioles Lungs Diaphragm
The Process of the Respiratory System Diaphragm brings air in and out of the lungs Air enters lungs, diaphragm contracts Travels down your ribs into the pelvic region, leaving a vacuum for air to fill the lungs. The air then fills in. This is the process of inhalation. Air travels through the bronchi to air sacs called alveoli Oxygen diffuses into blood stream Blood travels to the heart Gets pumped to the rest of the body
How the respiratory system maintains homeostasis in the body The respiratory system helps maintain homeostasis by regulating the intake of air into the body and by removing carbon dioxide from the blood. This then aids the circulatory system's function and many other operations in the body. Without these internal systems being properly balanced it can lead to a number of issues in the human body, including death, depending on the severity of the imbalance.
What causes inhalation to occur The thoracic diaphragm, located between the thoracic and abdominal cavities, contracts to create lower pressure within the thoracic cavity. The external intercostal muscles, located between the ribs, also aid in this process. This low pressure draws air into the lungs due to higher pressure in the atmosphere.
Disorders & Diseases that Affect the Respiratory System Lung Cancer: Uncontrollable cell growth in the lung. Unwanted cancerous growths keep the lung from Pulmonary Fibrosis: lung tissue becomes damaged and scarred. The stiff tissue makes it more difficult for your lungs to work properly Chronic Asthma: a lung disease that cause the airways to narrow and swell. This causes wheezing, chest tightness, shortness of breath, and coughing.
How the respiratory system interacts with the circulatory system The oxygen first enters your lungs and then into the left side of your heart. It is then pumped by the heart into your bloodstream. The circulatory system transports the carbon dioxide and oxygen inhaled by the respiratory system. The nervous system regulates the amount of carbon dioxide and oxygen inhaled.
Where the respiratory system interacts with the circulatory system The circulatory system consists of the heart, blood, and blood vessels. They interact when the oxygenated blood flows to the heart and is then distributed throughout the body sending oxygen throughout.
