Where does gaseous exchange in human take place?
Gaseous exchange in humans takes place in the alveoli of the lungs. Oxygen from inhaled air diffuses into the blood in the capillaries surrounding the alveoli, while carbon dioxide from the blood diffuses into the alveoli to be exhaled.
Why all gaseous exchange surfaces moist?
All gaseous exchange surfaces are moist to facilitate the diffusion of gases. Water vapor present in the moisture creates a concentration gradient, allowing oxygen and carbon dioxide to dissolve and diffuse more easily across cell membranes. Additionally, moisture helps maintain the structural integrity of the exchange surfaces, preventing them from drying out and ensuring efficient gas exchange. This is especially crucial in organisms like humans and plants, where respiration and photosynthesis rely on effective gas exchange.
Are humans natural structures?
No, humans are living organisms, not structures. Structures are typically inanimate objects that are constructed or formed by humans, whereas humans are biological beings that are part of the natural world.
Do single cell organisms have circulatory system like humans?
Single cell organisms do not have a circulatory system like humans because they are single-celled and do not have complex internal structures. Instead, they rely on simple diffusion for the exchange of gases and nutrients.
What is the difference between man made and natural structures?
man-made structures were made by humans, but natural structures made itself.
What plays a role in gas exchange?
haemoglobin present in the RBC helps in gaseous exchange and transport in humans .. where as in plants its through stomata , cuticle , lenticels etc....
What are the large spongy organs responsible for gas exchange in humans?
Lungs

Are humans responsible for earthquake?
yes humans are responsible
What is gaseas exchange?
Gaseous exchange is the biological process through which organisms exchange gases, primarily oxygen and carbon dioxide, with their environment. In humans and many animals, this occurs in the lungs where oxygen is inhaled into the alveoli and diffuses into the bloodstream, while carbon dioxide is expelled from the blood into the alveoli to be exhaled. In plants, gaseous exchange occurs through small openings called stomata, where carbon dioxide enters for photosynthesis and oxygen is released as a byproduct. This process is essential for maintaining cellular respiration and overall metabolic functions.
Are humans natural structures?

What is the definition of lungs?
The respiratory organs of air-breathing animals.
Why do humans use biomass?
for heating and cooking, gaseous fuel, and to create electricity
Can ozone hurt humans?
yes Ozone has been shown to exacerbate asthma symptoms. It also does the same sort of damage to the breathing structures of all organisms that exchange gases to / from the atmosphere.
Who is responsible for the harming planet earth?
humans are responsible
How does your body adopt surface area to volume ratio to help exchange gases-?
The skin surface is not large enough for big creatures such as humans; therefore we have structures in our lungs that greatly increase the surface area.
