What else can I help you with?
Why is it important that respiratory surfaces are moist and selectively permeable?
bronchioles.
What two structures do frogs use for gas exchange?
Frogs uses respiratory surfaces which totals to three to exchange gases on its surroundings. The three respiratory surfaces are the skin, its lungs, and the lining of their mouth.
How does the respiratory system move air to and from gas exchange surfaces?
diffusion
What Oxygen molecules absorbed by moist respiratory surfaces in humans diffuse immediately into?
Endocrine glands
What are three respiratory surfaces found in an adult frog?
the skin the lungs and the mucus membranes lining the throat
Why do gas exchange surfaces need to be moist?
The gases are to dissolve and diffuse through.
Why do cnidarians not need respiratory or excretory systems?
Jellyfish are, compared to mollusks, arthropods and vertebrates, very simple organisms. Jellyfish did not evolve a respiratory or an excretory system, as they can perform gas exchange at their outer surfaces.
How does the body remove microorganisms that make their way into the respiratory zone?
alveolar macrophages crawl freely along internal alveolar surfaces
Where is the portal entry for influenza is?
The entry point for the influenza virus is typically through the respiratory tract, such as the nose or mouth, when an infected person coughs or sneezes, releasing virus-containing respiratory droplets into the air. These droplets can then be inhaled or enter the body through contact with contaminated surfaces.
How long does RSV live on dry surfaces?
Respiratory syncytial virus (RSV) can survive on dry surfaces for several hours, typically ranging from 6 to 8 hours, depending on the material. Hard surfaces like plastic and metal may allow the virus to remain viable for longer periods compared to soft surfaces like cloth. Proper cleaning and disinfection are essential to reduce the risk of transmission.
Why is the respiratory surface inside terrestrial organisms?
The respiratory surfaces are inside terrestrial organisms to protect them from dehydration and damage. Having the respiratory surface inside allows for controlled gas exchange and efficient transport of gases throughout the body. Additionally, it helps to maintain a consistent internal environment necessary for optimal cellular function.
What does respiratory droplets mean?
Respiratory droplets are tiny liquid particles expelled from the respiratory tract when a person coughs, sneezes, talks, or breathes. These droplets vary in size and can carry pathogens, including viruses and bacteria, potentially leading to the transmission of diseases. Typically, respiratory droplets are larger than 5 micrometers and can travel short distances before settling on surfaces or being inhaled by others. They play a significant role in the spread of respiratory infections, such as influenza and COVID-19.
