What function do the alveolar sacs serve in the respiratory system?
Brrunno [24]

These alveoli are the smallest types of lung tissue, and one of the most important. In addition to being the primary means by which oxygen enters and carbon dioxide escapes the bloodstream, these small pouches of air are also the reason why the lungs do not totally collapse when a person breathes out. This is because they contain a cell that secretes a special chemical to lower the surface temperature to prevent lung collapse. The alveoli also contain other cells that secrete chemicals to attack and remove any foreign objects in the lungs, such as dust, dirt and other debris.

In addition to making up alveolar sacs, alveoli also form alveolar ducts. It is estimated that there are more than 300 million alveoli in the human lungs, all of which are located in either alveolar ducts or sacs that are found at the end of the smaller passageways, or bronchioles, in the lungs.


SHORT ANSWER:

Alveolar sacs contain tiny pouches called alveoli, whose primary function is gas diffusion. These clusters of alveoli have thin walls that allow oxygen to pass easily from the lungs into the bloodstream and carbon dioxide to flow from the blood to the lungs so it can exit the body.

Match these items. 1. taxonomic category within a kingdom fermentation 2. plant that lives on decaying organic matter host 3. br
Sonja [21]

1. taxonomic category within a kingdom-phylum

This taxonomic category is at level below Kingdom and above Class (e.g Arthropoda, Chordata, Mollusca)

2. plant that lives on decaying organic matter-saprophyte  

Saprotrophic plants or saprophytes use saprotrophic nutrition meaning that have extracellular digestion to process death organic matter.

3. break down of complex molecules into simpler ones- fermentation  

Fermentation is a metabolic process that breaks down organic substrates in order to obtain energy. These processes are performed without the presence of oxygen (anaerobic processes).

4. multi-nucleated thread-like structures of fungi hyphae

This is one of the basic structural unit of fungi-long, filamentous structure that can form network-micelium. It is used for vegetative reproduction.

5. mycelia responsible for obtaining food from non-living organic material rhizoids

Rhizodis are unicellular or multicellular stuctures (branching hyphae) found in fungi that are similar to root hairs of plants. These structures are involved in saprotrophic nutrition of fungi.

6. asexual reproduction of yeast budding  

Budding is a type of asexual reproduction in which a new organism develops from some generative anatomical part of the parent organism.

7. a group of hyphae mycelia

Mycelum is fungi’s vegetative body that consists of network of branching hyphae.

8. reproductive cells which can tolerate bad conditions spores

Spores are reproductive structure, part of the fungi life cycle, that can be involved in sexual or asexual reproduction, vary in structure that are formed in. Spores are usually haploid and unicellular.

9. structures which house the reproductive formation fruiting

Fruit is a structure in flowering plants that contains seed and it is responsible for seed dispersal and nutrition.

10. mutually positive relationship between two species symbiosis  

Symbiosis is biological interaction between two species that can be mutualistic, commensalistic, or parasitic. More specifically, symbiosis refers to positive interaction for both members of it.

11. plant or animal which supports a parasite host

Parasitic relationship between species is the one in which organism (the parasite), lives on or in another organism (host).This relationship is positive for parasite but negative for the host.
