Because they are the lining of the lungs that begin the process of taking oxygen out of the air and into the blood stream. They are the parts that actually coe into contact with the "air" and are therefore called the functional part of the lungs.
the answer is cellsLiving things are made up of cells which are made up of proteins which are made up of atoms mainly of Carbon, Hydrogen.All living things are made of cells All living things are made up of biological units called cells.waterAll living things are made up of cells. Cells
A waxy structure in a beehive is called a honeycomb. Honeycombs are made by honeybees from beeswax and serve as storage units for honey, pollen, and larvae.
A group of female lions is a 'pride'. (males are a 'coalition')
Morphology is the branch of linguistics that studies the structure and formation of words. It examines how words are built from smaller units called morphemes, which are the smallest meaningful units in a language. Morphology explores aspects such as word formation processes, inflection, and derivation, helping to understand how language conveys meaning through word structure.
Yes all living things are composed of cells.
Alveoli are the smallest functional units of the lungs. Therefore, they belong to the respiratory system.
Actually, the structure of the lunge is make up Visceral pleura, Parietal pleura, and Pleural cavity
Alveoli
They are genes.
The alveoli (singular, alveolus) are the functional units of the lungs of mammals.
The alveoli (singular, alveolus) are the functional units of the lungs of mammals.
Functional units of heredity are called genes. Genes are segments of DNA that contain instructions for building proteins, which determine an individual's traits and characteristics.
The alveoli (singular, alveolus) are the functional units of the lungs of mammals.
cell
for this reason ceall are called structural and functional units of life
Functional Units
DNA and RNA contain functional units known as nucleotides, which are composed of a sugar, a phosphate group, and a nitrogenous base. ATP (adenosine triphosphate) contains functional units called phosphate groups, which are crucial for the transfer of energy in cells.
