What is the purpose of the aveoli?
The alveoli are the sites of gas exchange in the lungs. They are round and numerous, so the surface area is maximised for increased volumes of oxygen and carbon dioxide to pass through. Their membranes are very thin, and they are surrounded by a network of capillaries to further increase the efficiency of the gas exchange process.
What are segregating sites in population genetics?
The nucleotide sites that are polymorphic within a set of sequences
Organelle works with the rough ER to package and ship new proteins to appropriate sites within the cell or for sectioning out of the cell?
The Golgi Apparatus.

Which part of heart allows for the exchange of nutrients and oxygen?
The exchange of nutrients and oxygen does not take place in the heart. The exchange of oxygen takes place in the alveoli of the lungs and the exchange of nutrients takes place at numerous sites around the body, but the most predominant is the duodenum and ileum of the small intestine.

How does the exchange of gases occur in humans and mammals?
In the lungs at the alveolar sites, carbon dioxide is detached and excreted and oxgygen binds to hemoglobin to be carried back to the heart, then pumped out to the body via the aorta.
How is co2 removed from the body?
We find that carbon dioxide is removed from the body via what is called gas exchange in the lungs. When we inhale, air is drawn into the lungs, and the alveoli in the lungs are the sites where gas exchange takes place. Carbon dioxide exits the blood, and oxygen enters. When we exhale, the carbon dioxide is carried out of the body, and the process is repeated with another breath.
Where does gas exchange occur between the lungs and blood?
An alveolus (plural: alveoli, from Latin alveolus, "little cavity") is an anatomical structure that has the form of a hollow cavity. Found in the lung parenchyma, the pulmonary alveoli are the dead ends of the respiratory tree, which outcrop from either alveolar sacs or alveolar ducts, which are both sites of gas exchange with the blood as well.
What is the purpose of the aveoli?
The alveoli are the sites of gas exchange in the lungs. They are round and numerous, so the surface area is maximised for increased volumes of oxygen and carbon dioxide to pass through.
