    • What is the respiratory system responsible for in the body?
      Breathing and gas exchange
    • Match the breathing phase with its definition:
      Inhale ↔️ Drawing air into the lungs
      Exhale ↔️ Pushing air out of the lungs
    • What are the bronchi?
      Airways branching from trachea
    • Where does oxygen diffuse into the bloodstream during gas exchange?
      Alveoli
    • During inhalation, the diaphragm and chest muscles contract
    • Match the respiratory process with its description:
      Inhalation ↔️ Drawing air into the lungs
      Exhalation ↔️ Pushing air out of the lungs
    • What characteristic of the alveoli maximizes gas exchange efficiency?
      Large surface area
    • The respiratory system is responsible for breathing and gas exchange.
    • What is the role of the trachea in the respiratory system?
      Connects nose to lungs
    • How does the diaphragm move during exhalation?
      Relaxes and moves upward
    • Which respiratory structure connects the nose or mouth to the lungs?
      Trachea
    • Steps involved in the mechanism of breathing:
      1️⃣ Diaphragm and chest muscles contract during inhalation
      2️⃣ Air is drawn into the lungs
      3️⃣ Gas exchange occurs in the alveoli
      4️⃣ Diaphragm and chest muscles relax during exhalation
      5️⃣ Air is pushed out of the lungs
    • During exhalation, carbon dioxide is expelled from the lungs through the trachea
    • During inhalation, the diaphragm and chest muscles contract, expanding the lungs.
    • The alveoli have a large surface area to maximize gas exchange efficiency.
    • Carbon dioxide is transported in the bloodstream by dissolving in plasma.

      True
    • What do peripheral chemoreceptors detect?
      Decreased oxygen levels
    • Gas exchange in the lungs occurs in the alveoli
      True
    • During gas exchange, oxygen is taken into the lungs, and carbon dioxide is expelled

      True
    • What are the three main structures through which air flows in the respiratory system?
      Trachea, bronchi, alveoli
    • Gas exchange in the alveoli allows oxygen to diffuse into the bloodstream and carbon dioxide to diffuse out.

      True
    • Oxygen diffuses from the alveoli into the blood
    • Match the gas with its transport mechanism in the blood:
      Oxygen ↔️ Attached to hemoglobin
      Carbon dioxide ↔️ Dissolved in plasma
    • Breathing involves both inhalation and exhalation.
      True
    • Match the breathing process with its definition:
      Inhale ↔️ Draw air into the lungs
      Exhale ↔️ Push air out of the lungs
    • What are the two main steps in the mechanism of breathing?
      Inhalation and exhalation
    • What happens to lung volume during exhalation?
      Reduces
    • Where does gas exchange occur in the lungs?
      Alveoli
    • What is the primary mechanism for gas exchange in the alveoli?
      Diffusion
    • How is oxygen transported in the bloodstream?
      Attached to hemoglobin
    • Where are central chemoreceptors located?
      In the brain
    • Match the respiratory disease with its cause:
      Asthma ↔️ Inflammation of airways
      Pneumonia ↔️ Bacterial, viral, or fungal infection
      COPD ↔️ Damage to airways, often from smoking
      Lung Cancer ↔️ Uncontrolled cell growth
    • Respiratory diseases can be caused by infections, environmental factors, or genetic factors.

      True
    • The trachea connects the nose/mouth to the lungs
    • During exhalation, the diaphragm and chest muscles relax
    • Steps in the mechanism of breathing
      1️⃣ Inhalation: Diaphragm and chest muscles contract
      2️⃣ Oxygen is taken into the lungs
      3️⃣ Air flows through the trachea, bronchi, and into the alveoli
      4️⃣ Gas exchange occurs in the alveoli
      5️⃣ Exhalation: Diaphragm and chest muscles relax
      6️⃣ Carbon dioxide is expelled from the lungs
    • What gas is taken into the lungs during inhalation?
      Oxygen
    • Where does gas exchange primarily occur in the lungs?
      Alveoli
    • Carbon dioxide diffuses from the bloodstream into the alveoli during gas exchange.

      True
    • What are the branches off the trachea that lead to the alveoli called?
      Bronchi
