Bronchodilator: This drug causes dilation‚ or enlargement‚ of the opening of a bronchus to improve ventilation to the lungs. An example is albuterol

Respiration. *The respiratory system consists of tubes that filter incoming air and transport it into the microscopic alveoli where gases are exchanged the entire process of exchanging gases between the atmosphere and body cells is called respiration and consists of the following: ventilation‚ gas exchange between blood and lungs‚ gas transport in the bloodstream‚ gas exchange between the blood and body cells‚ and cellular respiration *The organs of the respiratory tract can be divided into two

Anatomy of the Respiratory System Nose and Nasal Cavity The nose and nasal cavity form the main external opening for the respiratory system and are the first section of the body’s airway—the respiratory tract through which air moves. The nose is a structure of the face made of cartilage‚ bone‚ muscle‚ and skin that supports and protects the anterior portion of the nasal cavity. The nasal cavity is a hollow space within the nose and skull that is lined with hairs and mucus membrane. The function

The human respiratory system is one of the chief and most important which is very instrumental for survival. Prime function of the respiratory system is breathing. Inhaling oxygen and exhaling carbon dioxide is all that takes plays by function of the respiratory organs. Breathing is a process by which oxygen in the air is brought in to the lungs and further in to close contact with blood. The blood absorbs the oxygen and carries to all parts of the body. Simultaneously blood gives up waste matter

Respiratory System WebQuest Introduction The primary function of the respiratory system is to supply the blood with oxygen. The respiratory system does this through breathing. Breathing is a natural process that we use to obtain oxygen‚ unlike eating or drinking to get energy. When we breathe‚ we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system’s means of getting oxygen to the blood. The respiratory tract is responsible for taking the gases

immune system must recognize the pathogen as foreign and dispose of it. The overall immune system is divided into two separate systems that do work together to protect the body. The Innate system‚ is the initial immune response from childhood which functions in the same way whether or not the individual has already encountered the same pathogen. Whereas‚ the Adaptive system matures with a person as it adapts to the first encounter with the pathogen
