That sounds like a general description of the LUNGS.
The lungs are loaded with pulmonary alveoli: small outpouchings along the walls of the alveolar sacs and alveolar ducts; through them, gas exchange takes place between alveolar gas and pulmonary capillary blood.
what part of the lower respiratory tract is made up of tiny air sacs where oxygen and carbon dioxide are exchanged
No. The capillaries are part of the circulatory system.
Well the upper respiratory system consists of just the nose, pharynx, and larynx.
The capillaries surrounding the alveoli at the ends of the bronchioles in the lungs.
glomerulus
The circulatory system is composed of heart,arteries,veins and capillaries.
No. The esophagus is part of the digestive system. The pharynx is part of both the digestive and respiratory systems.
Arteries are part of the circulatory system, not the respiratory system.
The alveoli in the lungs are made of a wet wall that is one cell thick with a network of capillaries to facilitate gas exchange.
In the respiratory system, it is the alveoli.In the circulatory system, it's the capillaries.They are similar in that both have walls that are only one cell thick, they are both the thinnest parts of their systems, and they are right next to each other. (They diffuse through to each other.)In the respiratory system it's the Alveoli and in the circulatory system it's the capillaries :D
No. The kidneys are part of the excretory system.
The larynx belongs to the respiratory system.
Fish and humans both have a mouth which is part of the respiratory system. In addition, both have capillaries and alveoli.
