What structure helps in respiration?
The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.
What are the hairlike structures in your lungs?
The bronchus in the lungs are lined with hair-like projections called cilia that move microbes and debris up and out of the airways. Scattered throughout the cilia are goblet cells that secrete mucus which helps protect the lining of the bronchus and trap microorganisms.
What are the tiny hairlike structures that protect the lungs?
Tiny hairs called cilia (SIL-ee-uh) protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose through the breathed air.
Which structure in human respiratory system is involved in conditioning of air?
The larynx is a cartilaginous structure inferior to the laryngopharynx that connects the pharynx to the trachea and helps regulate the volume of air that enters and leaves the lungs. The structure of the larynx is formed by several pieces of cartilage.
Are the hairlike structure that connect to the alveoli?
The tubes are lined with fine hair-like structures called cilia. As the cilia sway back and forth, they carry the mucous upwards to the trachea where it can be coughed up or swallowed. At the end of the bronchial tubes are air sacs called alveoli.
What is the small hairs in the respiratory tract?
Your rib muscles also lift the ribs up and outward to give the lungs more space. At the same time, you inhale air through your mouth and nose, and the air heads down your trachea, or windpipe. On the way down the windpipe, tiny hairs called cilia (say: SILL-ee-uh) move gently to keep mucus and dirt out of the lungs.
What is the purpose of the tiny hairs called cilia in your nose?
Hairlike structures called cilia line the mucous membrane and move the particles trapped in the mucus out of the nose. Inhaled air is moistened, warmed, and cleansed by the tissue that lines the nasal cavity.
Which structure swirls incoming air and helps trap debris?
Mucous membrane containing cilia lines the trachea. The mucus produced by the membrane traps dust particles and other debris. The cilia move continuously in a direction opposite that of the incoming air, helping propel the mucus away from the lungs to the throat where it can be swallowed or spat out.
Which structures play the greatest role in warming and humidifying air?

What three structures make up the respiratory membrane?
It consists of the alveolar wall, the capillary wall, and their basement membranes.
What are the features of the respiratory system in humans?
The respiratory system in humans has the following important features: The energy is generated by the breakdown of glucose molecules in all living cells of the human body.
What is the function of the hair follicles in the nose?
Tiny hair follicles that cover the interior lining of nostrils act as the body’s first line of defence against foreign pathogens. Furthermore, they provide additional humidity for inhaled air. Two cartilaginous chords lay the framework for the larynx.
How is the upper respiratory system involved in conduction?
All of the organs and other structures of the upper respiratory tract are involved in conduction or the movement of air into and out of the body. Upper respiratory tract organs provide a route for air to move between the outside atmosphere and the lungs.
What is the epithelium of the respiratory system made of?
From the nose through the bronchi, the respiratory tract is covered in the epithelium that contains mucus-secreting goblet cells. The mucus traps particles and pathogens in the incoming air. The epithelium of the respiratory tract is also covered with tiny cell projections called cilia (singular, cilium), as shown in Figure 16.2. 7.
