Q. How is the respiratory system linked to the cardiovascular system?
The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart.

|---|---|
| Which of the following organs is not part of the lower respiratory system? | pharynx |
| The conchae | create turbulence in the air to trap particulate matter in mucus. |
| The openings to the nasal cavity are the | external nares. |
| The auditory tubes open into the | nasopharynx. |
Q. What are the structures of the upper and lower respiratory system?
The upper respiratory tract refers to following airway structures: nasal cavities and passages (sinuses), pharynx, tonsils, and larynx (voice box). Trachea (windpipe) and lungs with its substructures bronchi, bronchioles, and alveoli make up the lower respiratory tract.
Q. What part of the respiratory system carries out gas exchange?
Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.
Q. How does the lower respiratory tract develop?
Development of the lower respiratory tract begins on day 22 and continues to form the trachea, lungs, bronchi, and alveoli. The process divides into five stages: embryonic, pseudoglandular, canalicular, saccular, and alveolar stage.
Q. What is the first sign of development of respiratory system?
Respiratory development in the embryo begins around week 4. Ectodermal tissue from the anterior head region invaginates posteriorly to form olfactory pits, which fuse with endodermal tissue of the developing pharynx. An olfactory pit is one of a pair of structures that will enlarge to become the nasal cavity.
Q. What are the stages of the respiratory system?
Lung development can be divided into distinct stages: the pseudoglandular period, the canalicular period, and the terminal saccular period.
Q. Is the pharynx part of the lower respiratory tract?
The respiratory tract is divided into two main parts: the upper respiratory tract, consisting of the nose, nasal cavity and the pharynx; and the lower respiratory tract, consisting of the larynx, trachea, bronchi and the lungs. The upper respiratory tract consists of the nose, the nasal cavity and the pharynx.
Q. What are the four processes of the respiratory system?
Respiration consists of 4 distinct processes:
- Pulmonary Ventilation. moving air into and out of the lungs.
- External Respiration.
- Transport. transport of oxygen and carbon dioxide between the lungs and tissues.
- Internal Respiration. diffusion of gases between the blood of the systemic capillaries and cells.
Q. How do you get rid of a lower respiratory infection?
Medications
- Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, naproxen, or aspirin can relieve pain and fever.
- Acetaminophen can also provide relief from pain and fever.
- Using a bronchodilator inhaler can help wheezing and shortness of breath.
Q. How food is prevented from entering the lower respiratory tract?
When you swallow, a flap called the epiglottis moves to block the entrance of food particles into your larynx and lungs. The muscles of the larynx pull upward to assist with this movement. They also tightly close during swallowing. That prevents food from entering your lungs.
Q. What prevents food from going down your lungs?
A flap of tissue called the epiglottis sits over the top of the trachea. This flap blocks food and drink from going down into the trachea when you swallow. But in some cases, food or drink can enter the trachea causing aspiration.
