Why do leaves have a large surface area?
Leaves are broad, thin and flat to provide a large surface area, to absorb sunlight for photosynthesis. :)
Which structures provide a huge surface area for diffusion of gasses?
The structures that provide a huge surface area for the diffusion of gases are the alveoli in the lungs and the thin-walled capillaries surrounding them. Alveoli are tiny air sacs that dramatically increase the surface area available for gas exchange, allowing for efficient oxygen uptake and carbon dioxide release. Additionally, the branching structure of the bronchioles and the extensive network of capillaries contribute to this large surface area, facilitating rapid diffusion.
What is the function of the Alveoil?
Alveoli are tiny air sacs in the lungs that play a crucial role in the respiratory system. Their primary function is to facilitate gas exchange; they allow oxygen to enter the bloodstream while enabling carbon dioxide to be expelled from the blood. The thin walls of the alveoli, along with their large surface area, optimize this exchange, making them essential for efficient respiration.
How do you find the dimensions of a rectangular prism if you have the surface area?
It is not possible. For example, the prism could be tall and thin, or short and thick, and either way have the same surface area.
What does this mean 4millimeters x 2.3meters x 24meters?
It means that someone has recorded the dimensions of a thin object with rather a large area, possibly with the aim of calculating its volume. However, it is equally possible that the dimensions are recorded to establish its surface area (for painting?).

Why is it easy for gases to pass between air sacs and blood?
Gases can easily pass between air sacs and blood due to the thin barrier of the respiratory membrane. This barrier consists of a single layer of epithelial cells in the air sacs and a single layer of endothelial cells in the capillaries, allowing for efficient gas exchange through diffusion. Additionally, the large surface area of the alveoli and the high concentration gradient of gases between the air in the lungs and the blood facilitate rapid exchange.
Three ways in which the lungs are adapted for gas exchange?
Many alveoli-increases surface area for gas exchange Thin alveolar wall-allows gases to diffuse easily and fast Thin capillary wall-easy diffusion Inner wall of alveoli-allows gases to dissolve, which they need to enter the capillary
What is the main job of the alveoli?
The alveoli, the small sacs of air at the ends of the terminal bronchioles, are the sites of the exchange between oxygen and carbon dioxide.
What are thin-walled sacs in the lungs?
the thin-walled sacs in the lungs are the alveoli. they are tiny are sacks in your lungs.
What are thin-walled sacs in the lungs are?
the thin-walled sacs in the lungs are the alveoli. they are tiny are sacks in your lungs.
Why are root hair cells of a plant long and thin?
Root hair cells are long and thin to increase the surface area available for absorption of water and nutrients from the soil. This increased surface area allows for more efficient uptake of essential resources, supporting the plant's growth and development.
How does blood pick up oxygen from the lungs?
In the lungs, oxygen diffuses from the air sacs (alveoli) into the surrounding capillaries. These capillaries are thin-walled and have a large surface area for efficient gas exchange. The oxygen then binds to hemoglobin in red blood cells, forming oxyhemoglobin, which is then carried by the bloodstream to the tissues.
