• What is the function of a red blood cell?

  Transport oxygen around the body. (oxygen binds to form oxyhaemoglobin)
• What is the function of white blood cells

  Fight pathogens by engulfing, releasing antibodies and antitoxins
• What is the function of a plasma?

  Helps to clot blood and form a scab
• What is the function of platelets?

  Liquid component of blood transports urea, carbon dioxide, amino acids etc around body
• Write out the word equation for aerobic respiration

  Glucose + oxygen = carbon dioxide + water *energy*
• Nasal cavity

  The space inside your nose where air enters the respiratory system. The nasal cavity is lined with mucous membranes that help to warm, humidify, and filter the air before it reaches the lungs.
• Pharynx

  Also known as the throat, the pharynx is a tube-shaped structure that serves as a common passageway for both food and air. It is divided into three parts: the nasopharynx, oropharynx, and laryngopharynx.
• Bronchioles

  These are tiny, hair-like structures that branch off from the bronchi and lead to the alveoli.
• Alveoli

  These are tiny air sacs located at the end of the bronchioles. The alveoli are where the exchange of oxygen and carbon dioxide takes place between the lungs and the bloodstream.
• Diaphragm

  This is a large, dome-shaped muscle located at the bottom of the chest cavity. The diaphragm plays a crucial role in the process of breathing, as it contracts and relaxes to allow the lungs to expand and contract.
• Bronchi

  These are the two branches of the trachea that lead to the right and left lungs. The bronchi further divide into smaller branches called bronchioles.
• Trachea

  Also known as the windpipe, the trachea is a tube-shaped structure that extends downward from the larynx and divides into two branches called bronchi. The trachea is lined with rings of cartilage that help to keep it open and allow air to flow freely into the lungs.
• Larynx

  Also known as the voice box, the larynx is a small organ located at the top of the trachea. It contains the vocal cords, which vibrate to produce sound when air passes through them.
