Summary Introduction
Introduction:
The primary function associated with the respiratory system is breathing. The respiratory system in humans and other mammals is divided into two portions: conduction portion and gas exchange portion. The conduction portion consists of series of passageways that are involved in the transport of gases while gas exchange portions are involved in the exchange of gases. As air moves by bulk flow into lungs and out of lungs, gases enter and exit the blood by diffusion within the lungs.

Students have asked these similar questions
with every breath we breathe in oxygen and breathe out co2. in terms of the specific cellular location, the oxygen is used in the _____ and the co2 is produced in the ________.
Two end products of respiration are:
oxygen and water.
glucose and oxygen.
carbon dioxide and oxygen.
carbon dioxide and water.
The respiratory process involves hemoglobin (Hgb), an iron-containing compound found in red blood
cells. In the process, carbon dioxide diffuses from tissue cells as molecular CO2, while O2 simultancously
enters the tissue cells. A significant fraction of the CO, leaving the tissue cells enters red blood cells and
reacts with hemoglobin; the CO, that does not enter the red blood cells (O in the figure below) remains
dissolved in the blood and is transported to the lungs. Some of theCO, entering the red blood cells reacts
with hemoglobin to form a compound (Hgb-CO, 2 in the figure). When the red blood cells reach the
lungs, the Hgb-CO, dissociates, releasing free CO,. Meanwhile, the CO, that enters the red blood cells
but does not react with hemoglobin combines with water to form carbonic acid, H¿CO3, which then
dissociates into hydrogen ions and bicarbonate ions (O in the figure). The bicarbonate ions diffuse out of
the cells (O in the figure), and the ions are transported to the lungs…

- What causes air to enter human lungs? The contraction of the diaphragm increases the volume of the lungs, decreasing the pressure relative to the air outside the body. Smooth muscle in the trachea guides the flow of air into the lungs. Air diffuses into the lungs due to the decreased O2 content relative to the air outside our body. The cilia in the trachea guide the flow of air into the lungs. The decreased concentration of O2 in the lungs decreases the density of that air and denser air outside the body "sinks" into the lungs.arrow_forwardWhat products are formed during respiration?

- Scientists were studying the effects exercise (running on a treadmill) has on the amount CO2 production and breathing rates on humans. Their conclusion was that a person who just completed a bout of exercise would have higher CO2 production and increased breathing rates when compared to when they were sitting in a chair. They also found that CO2 production and breathing rates would increase the longer they exercised. Based upon what we know about cellular respiration and energy production, select the reason that best explains the results of the testing above, CO2 production increases because CO2 is being made in the electron transport chain to keep the electrons moving. Breathing rates will increase in order to get rid of the lactic acid from working muscles. CO2 production increases because more of this is made as a direct result of glucose being split for energy. Breathing rates will increase with exercise in order to supply the muscles with more O2.
