What are the functions of the human respiratory system?

  • It includes the windpipe, the lungs and the nose. The respiratory system lets us breathe in oxygen through the nose, going down through the windpipe to the lungs, and then after it has travelled all around our body, comes up the windpipe into our nose as carbon dioxide as we breathe out.

  • Answer: It includes the windpipe, the lungs and the nose. The respiratory system lets us breathe in oxygen through the nose, going down through the windpipe to the lungs, and then after it has travelled all around our body, comes up the windpipe into our nose as carbon dioxide as we breathe out.
  • Answer: The respiratory systems of all mammals are very much the same.There is not much difference between them at all.
  • Answer: the respiration function where the respiratory system reach oxygen to the blood then the heart pump the blood that contain oxygen to the body cells.
  • Answer: The primary functions of the respiratory system is to:
    -supply oxygen to the blood
    -ventilate the lungs
    -excrete water vapour and carbon dioxide
    -maintain the pH (percent hydrogen) of blood
    -conduct respiration
    -regulate gas exchange
    -release energy
  • Answer: The respiratory system takes in oxygen and gets rid of carbon dioxide so you can breathe.
  • Answer: Exchange of gasses required for life, intake of oxygen from air and expiration of carbon dioxide from body. The respiratory system of humans functions sometimes to help maintain the pH of the body, and can be involved in temperature control in animals, such as panting in dogs.
  • Answer: You know how you breathe in and out? How your chest swells and lowers? It is due to the diaphragm. It rises and falls as you breathe allowing your lungs to fill with as much oxygen as possible and remove as much carbon dioxide as possible. Other than this I know no other purpose.
  • Answer: The respiratory system basically has Gas exchange functions, Excretion function, filtration function as well as acid base balance.
  • Answer: The three secondary functions of the respiratory system are vocalization, temperature control, and coughing / sneezing.
  • Answer: Circulatory, nervous, endocrine, lymphatic, and digestive systems all fail without adequate respiration.
  • Answer: The physiological function of the respiratory system is helping our body breathe clean air (oxygen) and breathing out carbon dioxide.
  • Answer: Nasal Cavity, Pharynx, Larynx, Trachea, Bronchi, Bronchioles, Alveoli

    Nasal cavity- The nasal cavity has three key components: vestibule, main nasal cavity and the paranasal sinuses. Here we see the vestibule, the area within the nostril. The epithelium here represents a continuation of the keratinized, stratified squamous epithelium of the outside skin. Within the vestibule are vibrissae (hairs) that serve to filter out the larger particles entering in the inhaled air
    Pharynx- essentially same cell type, dont forget the mucous secretions- essentially same fxn

    Larynx- The larynx is situated between the pharynx and the trachea.

    he pharynx is situated between the nasal cavity and the larynx. The portion exclusively used for breathing (nasopharynx) is lined by the usual pseudostratified ciliated epithelium (respiratory epithelium) found throughout most of the conducting portion of the respiratory system. The remaining components of the pharynx (oropharynx, hypopharynx) are lined by a protective stratified squamous epithelium, appropriate to their role in abrasive activities such as swallowing and coughing.

    The trachea extends from the larynx to the primary bronchi of the lung. It consists of a series of C-shaped hyaline cartilage rings that keep the airway open (the esophagus, which lacks such rings, is collapsed except when swallowing). The posterior, open ends of the cartilage rings are connected by trachealis muscle. This muscle contracts to narrow the trachea during coughing, providing a faster air flow. Elastic fibers in the mucosa and submucosa provide flexibility to the trachea

    After the trachea, inspired air passes to the bronchi, distributing bronchioles, respiratory bronchioles, alveolar ducts, alveolar sacs and alveoli. Gas exchange occurs in alveoli, which first appear on the respiratory bronchioles.

  • Answer: The respiratory system is the group of organs in the human bodywhich work together to make you breathe.
  • Answer: The human respiratory system is responsible for the intake andexchange of oxygen and carbon dioxide. This system consists of thelungs, trachea, bronchi, bronchioles, and the diaphragm.
  • Answer: It includes the windpipe, the lungs and the nose. The respiratory system lets us breathe in oxygen through the nose, going down through the windpipe to the lungs, and then after it has travelled all around our body, comes up the windpipe into our nose as carbon dioxide as we breathe out.
