➡️ What is the Respiratory System?
The respiratory system is a term that describes the biological structures of the human body that are involved in gas exchange. Gas exchange is the physiological process of diffusion where oxygen moves from the lungs to the bloodstream during inhalation, and carbon dioxide moves from the blood to the lungs for removal during exhalation.

➡️ Respiratory System Structures
The respiratory system is made up of several organs and structures that work together to facilitate breathing, including:
- Lungs
- Trachea
- Upper airway
- Lower airway
- Alveoli
- Blood vessels
- Chest wall
- Diaphragm
- Accessory Muscles
- Pleural membranes

➡️ Lungs
The lungs are the primary organ of the respiratory system. They are responsible for inhalation and exhalation, which is how the body is able to take in oxygen while removing carbon dioxide.

➡️ Trachea
The trachea is a tube made of cartilage that connects the larynx to the airways of the lungs so that breathing can occur. It is lined with cilia, which are tiny hairs that help to filter out dust and other particles from reaching the lungs.

➡️ Upper Airway
The upper airway includes the pharynx and nasal cavities. These structures act as the initial passageway for air and are lined with mucus, which helps trap dust and debris.

➡️ Lower Airway
The lower airway refers to the portion of the respiratory system that includes the bronchi, bronchioles, and alveoli. During inhalation, air passes through the upper and lower airways before finally reaching the alveoli.

➡️ Alveoli
The alveoli are tiny air sacs that are arranged in clusters within the lungs. They are responsible for the gas exchange of oxygen and carbon dioxide molecules. Once air enters the alveoli, it diffuses across the alveolar membrane and into the bloodstream.

➡️ Blood Vessels
The blood vessels of the respiratory system transport oxygen throughout the body, while also carrying carbon dioxide away from cells for removal via exhalation. These vessels include arteries, veins, and capillaries.

➡️ Chest Wall
The chest wall refers to the bony structures that surround and protect the lungs, such as the ribs and sternum.

➡️ Diaphragm
The diaphragm is the primary muscle of respiration that lies beneath the lungs. It separates the thoracic cavity from the abdominal cavity. During inhalation, it contracts and flattens.

➡️ Accessory Muscles
Certain accessory muscles may also assist with breathing by helping lift the ribs during inhalation. This includes the abdominal muscles, internal intercostals, sternocleidomastoid, scalene, and pectoralis major.

➡️ Pleural Membranes
The pleural membranes are two thin layers of tissue that surround and protect the lungs. They are lubricated by pleural fluid, which helps to reduce friction during breathing.
