How does emphysema affect the removal of CO2 from the blood and delivery of oxygen to cells?
In emphysema there is actual breakdown of the alveoli; the tiny air sacs where oxygen and carbon dioxide are exchanged in the lungs. When they are broken down they are replaced with scar tissues and and a loss of surface area. Human lungs have an area about the size of a tennis court when all the alveoli are healthy. A person with emphysema may have only a fraction of that available area for the gas exchange to occur. That is why they end up needing a respirator, so more concentrated oxygen can enter their partially functioning lungs so that they can get enough oxygen into their blood stream.
What chemical alteration of the blood stream results from emphysema?
Emphysema is a type of chronic obstructive pulmonary disease (COPD) that is characterized by damage to the air sacs in the lungs. This can result in decreased oxygen levels in the blood (hypoxemia) and increased carbon dioxide levels (hypercapnia), leading to respiratory acidosis. Over time, these chemical alterations can affect the body's pH balance and lead to further complications.
What blood contains more oxygen?
Arterial blood typically contains more oxygen than venous blood. Arterial blood is oxygen-rich because it comes directly from the lungs after picking up oxygen, while venous blood has delivered its oxygen to the tissues and is returning to the heart to pick up more.
Do people with emphysema have a higher breathing rate than someone who does not have the decease?
People with emphysema typically have a higher breathing rate because their lungs are less efficient at oxygen exchange due to damage to the alveoli, leading to reduced oxygen levels in the blood. This causes the body to compensate by increasing the breathing rate to try to maintain adequate oxygen supply.
Which blood contains more oxygen?
The blood in arteries contains more oxygen because it is being pumped from the heart to the rest of the body. Oxygen is carried by red blood cells in the form of oxyhemoglobin.
How does emphysema reduce oxygen in blood?
the tar like substance prevents your lungs from taking in enough oxygen.
Why patient with emphysema thin?
Because emphysema reduce the oxygen perfusion (transfer) from alveoli into the blood thus also reduce the oxygen supply to the muscle and organ. Reduce the oxygen delivery to the periphery cause weight loss and thus they (emphysema patient) look thin.
What happens to blood gases in a patient with emphysema?
Decreased Oxygen, increased CO2, Acidosis
What are some reasons high carbon dioxide and low oxygen in the blood?
COPD -emphysema and chronic bronchitis
Explain how changes in the alveolar structure cause a decrease in the blood oxygen levels in emphysema?
Decrease in alveolar surface area results in less boundary across which oxygen can be absorbed into the blood.

What can Blood gas levels diagnose?
Low oxygen and high carbon dioxide levels are often indicative of chronic bronchitis, but not always of emphysema
What are the substances carried by blood and their functions?
Blood carries oxygen through out your body. Your lungs inhale oxygen and the blood cells carry the oxygen to your heart. Then the heart makes more blood cells to carry more oxygen to pump more blood.
Explain how the changes in alveolar structure cause a decrease in blood oxygen levels in emphysema?
Pneumonia fills the lung's alveoli with fluid, keeping oxygen from reaching the bloodstream.
Why does the arterial Po2 decrease with emphysema?
emphysema is a condition of loss of elasticity of the alveoli where exchange of oxygen and Co2 occurs. The alveoli cannot efficiently exchange oxygen for Co2 so Co2 builds up in the blood. It is usually caused by chronic smoking but can be caused by other diseases/conditions.
Why does blood circulate from the heart to the lungs?
The oxygen poor blood (not enough oxygen) goes to the lungs to get more oxygen to turn into oxygen rich blood (has plenty of oxygen)
