the lungs are protected with a db layer serous membrane. 1: is the superficial layer called the Parietal pleura that line the walls of the thoracic cavity. 2: The deeper layer is the visceral pleura, which cover the lungs themselves. In between the both membranes is a small space(cavity)filled with pleurisy to reduce friction.
What else can I help you with?
The parietal pleura would represent a serous membrane?
Yes, the parietal pleura is a serous membrane that lines the walls of the thoracic cavity. It helps protect and cushion the lungs, allowing them to move smoothly during breathing.
What walls exchange oxygen and carbon dioxide during respersation?
The walls of alveoli in the lungs are responsible for the exchange of oxygen and carbon dioxide during respiration. These thin membranes allow for the diffusion of gases between the air in the lungs and the bloodstream, facilitating the exchange of oxygen for carbon dioxide and vice versa.
What reduces the friction between the lungs and the walls of the thorax?
The pleural fluid reduces the friction between the lungs and the walls of the thorax by lubricating the pleural surfaces. This fluid allows the lungs to move smoothly during respiration without causing friction or resistance.
Do cheetahs have cell walls or membranes?
Cheetahs do not have cell walls. However, like all living organisms, they have cell membranes that surround and protect their cells. Cell membranes regulate the passage of substances in and out of the cell.
Do fungi have cell membranes?
Yes. Like plants they have both cell membranes and cell walls (but the cell walls have a different composition).
How many thoracic nerves?
thoracic nerves [T1-T12] twelve nerves on each side, mixed motor and sensory, supplying the muscles and skin of the thoracic and abdominal walls.
What is one way that members of archaebacteria are different from eubacteria?
They have different types of cell walls and cell membranes.
What are cell walls and cell membranes made of?
cell
Is cell walls found in animals?
Cell membranes are found in animal cells but not cell walls.
Why can the lungs expand and contract Is it because of muscular walls?
The lungs can expand and contract due to the presence of specialized muscles called the diaphragm and intercostal muscles that help regulate the volume of the thoracic cavity. When these muscles contract, the volume of the chest cavity increases, causing air to flow into the lungs (inhalation). When these muscles relax, the volume decreases, causing air to flow out of the lungs (exhalation).
What is the thin barrier that allows for the efficient exchange of gases between the lungs and the blood called?
The thin barrier that allows for the efficient exchange of gases between the lungs and the blood is called the respiratory membrane. It consists of the alveolar walls, capillary walls, and their basement membranes. This structure is essential for the diffusion of oxygen and carbon dioxide during respiration.
Is the cell wall located inside the cell membrane?
Plant cells have cell walls, animal cells have cell membranes. Cells do not have both walls and membranes, they have one or the other.
