Best answer: What structure protects the lungs from injury?

Your lungs are protected by your rib cage, which is made up of 12 sets of ribs. These ribs are connected to your spine in your back and go around your lungs to keep them safe.

What body structure protects the lungs from physical injury?

The sternum, or breastbone, is a long, flat, bony plate that forms the most anterior section of the rib cage. The primary function of the sternum is the protection of the heart, lungs, and blood vessels from physical damage.

Which membrane protects lungs from injury?

The pleural membranes are two layers of serous membrane which enclose and protect the lung. The superficial layer is called parietal pleura and lines the wall of the thoracic cavity. The deep layer is called visceral pleura and covers the lungs themselves.

Which structures function to protect the lungs?

Ribs: Bones that surround and protect your lungs and heart.

What type of structure surrounds the lungs?

Each lung is invested by and enclosed in a serous pleural sac that consists of two continuous membranes. The visceral or pulmonary pleura invest the lungs, The parietal pleura line the pulmonary cavities and adhere to the thoracic wall, mediastinum and diaphragm.

What happens if a pleural membrane is damaged?

If the pleural layers are ruptured, for example by a spontaneous rupture of the membrane or by a stab wound, air is sucked into the intrapleural space creating a real air-containing space between the lungs and chest wall – a pneumothorax.

What is the name of the membrane that covers the lungs?

There are two layers; the outer pleura (parietal pleura) is attached to the chest wall and the inner pleura (visceral pleura) covers the lungs and adjoining structures, via blood vessels, bronchi and nerves.

What keeps friction between the lungs and the thoracic cavity to a minimum?

The pleura fluid itself has a slightly adhesive quality that helps draw the lungs outward during inhalation rather than slipping round in the chest cavity. In addition, pleural fluid creates surface tension that helps maintain the position of the lungs against the chest wall.

What function do lungs perform?

The main function of the lungs is the process of gas exchange called respiration (or breathing). In respiration, oxygen from incoming air enters the blood, and carbon dioxide, a waste gas from the metabolism, leaves the blood.

How do structures in the respiratory system interact to protect the lungs?

Cilia propel a liquid layer of mucus that covers the airways. The mucus layer traps pathogens (potentially infectious microorganisms) and other particles, preventing them from reaching the lungs.
