The respiratory surface in humans is called the alveoli. These tiny, balloon-like structures are located in the lungs and are the primary sites for gas exchange, allowing oxygen to enter the bloodstream and carbon dioxide to be expelled. The large surface area of the alveoli, along with their thin walls, facilitates efficient diffusion of gases.

What is the name of the respiratory surface in humans?
The respiratory surface in humans is called the alveoli. These tiny air sacs in the lungs are where gas exchange occurs, with oxygen from the air we breathe passing into the bloodstream and carbon dioxide moving out.
In humans the respiratory surface is the walls of the?
alevoli
How has the efficiency of respiratory surface increased from fishes to human being?
The efficiency of the respiratory surface has increased from fishes to humans primarily due to the evolution of more complex respiratory structures. Fish utilize gills, which have a large surface area due to their thin filaments and lamellae, but human lungs feature extensive branching and alveoli, allowing for a much greater surface area for gas exchange. This adaptation enables humans to meet higher metabolic demands and efficiently exchange oxygen and carbon dioxide. Additionally, the presence of a diaphragm in humans enhances airflow and ventilation, further increasing respiratory efficiency.
What is the respiratory pigment of an earthworm?
the respiratory pigment in humans is hemoglobin
What is a respiratory disease that is spread between humans?
its called dentavacsine discovered by Edward Jenner
What are respiratory surfaces?
Respiratory surface is the surface where respiratory gas exchange in an animal. Ex-lungs
In humans the dorsal surface can also be called?
Posterior
Why is oxygen not exchanged directly through the body surface in humans?
Oxygen is not exchanged directly through the body surface in humans because our skin is not specialized for efficient gas exchange like the respiratory system. The respiratory system, with organs like lungs and specialized structures like alveoli, is more suited for rapid and effective oxygen exchange needed for sustaining complex human physiology.
What is the respiratory surface for protists?
the respiratory surface for protists is the alveolis and capillaries
Respiratory passages are lined with?
Little hairs called cilia. Get on my level
What are the vessels called closest to the surface of the skin in humans?
Superficial.
How are fish's respiratory system different from humans respiratory system?
cos day breathe in H2O innit and there trachea is more complex and blood vessels spread out on the gills to create a bigger surface area. :)
