Questions and Answers

What is the main function of the respiratory system?

Filtering waste products from the blood

Generating energy for muscle contractions

Producing hormones for cellular respiration

facilitate rhe exchange of gases within the body. oxygen diffuses from the alveoli to the capillary and carbon dioxide and wastes diffuse from the capillary to the alveoli. (correct)

Which organ is responsible for warming and humidifying air as it enters the body?

Bronchi

Lungs

Nose and nasal cavity (correct)

Pharynx

What is the purpose of hairs and mucus in the nose?

To regulate blood pressure

To help in speaking clearly

To trap debris and prevent it from reaching the lungs (correct)

Study Notes

Cellular Respiration and Gas Exchange

Cells in the body need oxygen for cellular respiration and a way to remove carbon dioxide
The circulatory and respiratory systems work together to supply oxygen and remove carbon dioxide from cells

Structure of the Respiratory System

Organs of the respiratory system: nose, trachea, bronchi, and lungs
Air enters the body through the mouth and nose
Nasal cavity is lined with mucous membranes that warm and humidify air
Nose hairs and mucus trap debris, preventing it from reaching the lungs

Nose, Pharynx, and Larynx

Pharynx (throat) is the region from the nasal cavity to the top of the trachea and oesophagus
Epiglottis is a flap of elastic cartilage that covers the oesophagus during inhalation and the larynx during swallowing
Larynx (voice box) is a cartilage structure that contains vocal cords, which vibrate to produce sound

Trachea

Trachea (windpipe) carries air into and out of the lungs
Made up of C-shaped cartilage rings that hold the structure open
Trachea splits into two branches, one for each lung
Epithelial lining of the trachea produces mucus that traps dust and debris
Cilia in the trachea move in a wave-like motion to remove mucus and debris

Bronchi

Trachea splits into two primary bronchi, one for each lung
Bronchi further divide into secondary and tertiary bronchi, taking air into each lobe of the lung
