Does oxygen move from the alveoli into the bloodstream?
i dont noww , alveoli is stupid
How are alveoli atapted to maximise diffusion?
i dont know??????????
What are the three stages of respiratory system?
The Process of the Respiratory System I am a Respiratory Therapist, so this is easy for me. During inspiration, air(gas) enters either through the nose or the mouth. As the air reaches the throat it becomes warmed and humidified and then passes into the trachea. It follows the trachea down into the bronchi then to the bronchioles(smaller versions of the bronchi) then into the alveoli. The alveoli are tiny sacs at the end of the bronchioles that look like clusters of grapes. After the air(gas) enters the alveoli, the oxygen from the air crosses the alveolar-capillary membrane and enters the blood. The blood then carries the oxygen to the organs of the body. During expiration, as the oxygen in the alveoli is entering the blood, carbon dioxide leaves the blood, enters the alveoli and is breathed out.
Can insects use their respiratory systems to make noise?
i dont no:(
What are the parts of the conducting zone of the respiratory system?
Nasal Cavity, Pharynx, Larynx, Trachea, Bronchi, Bronchioles, AlveoliNasal 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 airPharynx- essentially same cell type, dont forget the mucous secretions- essentially same fxnLarynx- The larynx is situated between the pharynx and the trachea.Photographs of the larynx in situ. The vocal folds separate during breathing and lie close together to vibrate during phonationThe 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 tracheaAfter 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.Please check out a physiology or histology book for more info
Do flatworms have a need for circulatory or respiratory systems?

What is the collapse of one or more alveoli called?
i really dont know... thats why im asking it
What does a trachea cell do?
Goblet cells embedded within the epithelium trap debris that we inhale. The cilia motion upward to 'beat' the debri upward passed the larynx to either be swallowed, sneezed, or coughed out. The purpose is to expel the debri so that it does not enter the lower respiratory tract.
What layer of GI tract is responsible for forming sphincters?
im sorry i dont know
