What are the hollow spheres of cells within the lungs where oxygen and carbon dioxide are exchanged?
The alveoli are the hollow spheres of cells within the lungs where oxygen and carbon dioxide are exchanged. They are thin-walled, and closely associated with the thin-walled capillaries that surround them. Oxygen and carbon dioxide diffuse across these thin walls to move from the blood to the lungs.

What are hollow spheres in a limestone rock called?
Hollow spheres in limestone rock are called vugs. Vugs are formed when a cavity in the rock is later filled with minerals or crystals. They can vary in size and shape and are often sought after by collectors for their unique beauty.
What are Hollow spheres in limestone?
Hollow spheres in limestone, often referred to as "concretions" or "geodes," are spherical formations that can form within sedimentary rocks. These structures typically occur when minerals precipitate from groundwater, leading to the growth of a hollow cavity lined with crystalline material. The process often involves the accumulation of minerals such as calcite or quartz, resulting in visually striking formations. Their unique shapes and internal structures can provide insights into geological processes and the environment of formation.
What is the shape of allotrope of carbon called buckminsterfullerene?
A hollow soccer ball
What is a form of pure carbon with atoms arranged in the shape of a long hollow tube?
You've described a carbon nanotube.
What is a form of carbon that consists of atoms in the form of a long hollow cylinder?
fullerene
What is the colonial flagellate hypothesis?
Multi-cellular animals also called metazoans came from protists which were colonilized. These colonies of protists formed hollow spheres. These protists which were linked together into a hollow sphere may have had some form of specialization to then make tissue.
Why are metal bodes designed to store charge made from large hollow spheres?
Large hollow spheres are used for metal bodies designed to store charge because they have a uniform electric field inside and the charges remain on the outer surface. This design minimizes the potential for internal charges to interfere with the stored charge, and it also maximizes the amount of charge that can be stored due to the large surface area of the sphere.
Are human lungs hollow inside?
Their principal function is to transport oxygen from the atmosphere into the bloodstream, and to release carbon dioxide from the bloodstream into the atmosphere. This exchange of gases is accomplished in the mosaic of specialized cells that form millions of tiny, exceptionally thin-walled air sacs called alvioli
What are microscopic spheres of 60 atoms of pure carbon in a spherelike structure that resembles a geodosic dome?
Those are known as buckminsterfullerene or buckyballs, which are a type of fullerene molecule. They consist of 60 carbon atoms arranged in a hollow sphere resembling a geodesic dome, with a structure resembling the geodesic dome designed by architect Buckminster Fuller, hence the name. Buckyballs have unique properties and are a subject of scientific research for various applications.
What is the hollow sphere of cells that expand and contract with each breath?
The hollow sphere of cells that expands and contracts with each breath refers to the alveoli, the tiny air sacs in the lungs. Alveoli are crucial for gas exchange, allowing oxygen to enter the bloodstream and carbon dioxide to be expelled. They are surrounded by a network of capillaries and are essential for efficient respiration. Their elasticity enables them to inflate and deflate during inhalation and exhalation.
How does oxygen and carbon dioxide get in and out of an amniotic egg?
The entire shell of the egg is covered in tiny little pores which allows for the passage of air and water into and out of the egg. The shell itself is recognized as a semi-permiable membrane. There is a chamber between the inner and outer soft membranes of the eggs (located just under the shell) that is actually hollow; it's an air cell. It grows as the chick does, surprisingly, but that's because as the chick gets older, it requires more CO2 to be transferred out of the egg, while allowing enough fresh oxygen to enter into the egg. The chick doesn't actually breathe into this chamber, the gasses are exchanged via an organ called the "allantois". This organ is responsible to handling liquid wastes and exchanging gases from the egg's air cell to the chick.
A form of pure carbon with atoms arranged in the shape of a hollow sphere?
The form of pure carbon with atoms arranged in the shape of a hollow sphere is called a fullerene. Fullerenes, also known as buckyballs, were first discovered in 1985 and have unique properties that make them of interest for various applications, such as in nanotechnology and drug delivery systems.
