What are the functions of the respiratory system?

​Ventilation vs. Respiration

Ventilation

bulk movement of air in and out of the respiratory system

Respiration

process of gas exchange that occurs in the lungs in which oxygen is added to the blood and carbon dioxide is removed.

​The Upper Respiratory Tract

• The upper airway is responsible for initially conditioning the inhaled air.
  

• It consists of the nose, mouth, pharynx, and larynx

Multiple Choice

What are the three regions found in your nasal cavity?

• vestibular, olfactory, respiratory regions

• olfaction, phonation, respiration regions

• nasopharynx, oropharynx, laryngopharnx

​Vestibular region

• filter out large particles

• vibrissae

  • coarse nasal hairs; first line of defense

  • lined with sebum

Respiratory region

• warms the inhaled air

• conchae or turbinates

  • provides more surface area for air to make contact with warm and moist nasal mucosa

Olfactory region

• found in the roof of the nasal cavity

• olfactory receptor

​Mucociliary Escalator

Multiple Choice

The pseudostratified ciliated columnar epithelium in the airways is often called the mucociliary escalator because:

• It absorbs oxygen into the blood while moving mucus

• It propels mucus and debris toward the oral cavity for expulsion or swallowing

• It secretes digestive enzymes into the airways to break down particles

• It strengthens the airway walls against collapse

​Pseudostratified Ciliated Columnar Cells

cilia - super rowers; "oars"

goblet cells & submucosal glands - produce mucus

Uvula & soft palate - move backwards when swallowing to prevent food and liquid from entering the nasal cavity

tonsils - fights infection; contain a lot of white blood cells

Labelling

Pharynx, a passageway for air, food, and liquids between the nose/mouth and trachea, has different parts. Shown is a picture of the pharynx. Label its different parts correctly.

Open Ended

The cartilage found in the anterior portion of the trachea is in the form of C-shaped structures to provide rigidity and protection. Why is the C cartilage that supports the trachea opens up at the posterior side?

It is important to note that the tissue layers of the bronchial walls are all the same, only smaller, as they branch downward.

​

• gas exchange unit of the lungs

• alveoli surrounded by capillaries

Multiple Choice

Which type of alveolar cell produces the surfactants? What is the importance of surfactants?

• produces by Type I squamous pneumocytes for easy diffusion of gases

• produces by Type I squamous pneumocytes for reducing surface tension

• produces by Type I I granular pneumocytes for easy diffusion of gases

• produces by Type II granullar pneumocytes for reducing surface tension

​LUNGS

• a pair of spongy, air-filled organs in the chest that allow the body to take in oxygen from the air and remove carbon dioxide from the blood

• protected by the rib cage and covered by a double-layered pleura that helps them expand and contract smoothly during breathing.

Multiple Choice

Why is the left lung smaller than the right lung?

• The left and right lung are of same size.

• The left lung is smaller due to a genetic mutation.

• The left lung is smaller to accommodate the liver.
• The left lung is smaller to make room for the heart.
