Answer:</h3>
Asthma
Asthma is a chronic illness that results in difficulty breathing, especially when doing strenuous activity. This is because people with asthma have narrow airways that can be restricted by mucus.
<h3>Other Answer Choices</h3>
Anemia
Anemia is defined as a lack of red blood cells, most commonly linked to an iron deficiency. Without the proper red blood cells, the body cannot transport oxygen like it is supposed to.
This results in:
- Headaches
- Dizziness
- Lightheadedness
- Fatigue
- Increased heart rate
Arthritis
Arthritis is the inflammation of the joints. Arthritis has a wide range of causes like infection, tearing, or other diseases. Arthritis is usually found in the elderly.
Symptoms include:
- Pain in the joints
- Stiffness in the joints
- Swelling
- Decreased range of motion
- Fatigue
Arteriosclerosis
Arteriosclerosis is the build-up of cholesterol in the arteries that blocks the flow of blood. Like arthritis, arteriosclerosis is linked to old age but can be avoided through exercise and a healthy diet.
It is possible to have no symptoms of arteriosclerosis, but it can be tied to:
- Pain in the leg
- Heart attacks
- Strokes
- Death
Answer:
The correct pathway for oxygen-poor blood is right atrium → right ventricle → pulmonary artery → lungs (first option).
Explanation:
Unoxygenated or oxygen-poor blood is that which comes from tissues that have exchanged O₂ for CO₂. The venous return is in charge of taking that blood to the heart and then to the lungs.
- Oxygen-poor blood reaches the <u>right atrium</u> from the vena cava.
- From the atrium the blood passes to the <u>right ventricle</u> through the tricuspid valve.
- The <u>right ventricle pumps the blood to the lungs</u> through the pulmonary arteries, the only arteries that carry venous blood.
Once in the lungs, the blood exchanges CO₂ for O₂, returning to the heart through the pulmonary veins.
The other options are not correct because:
- <em><u>Left atrium, left ventricle, aorta, body</u></em><em> corresponds to the flow of oxygenated blood that comes from the lungs and is pumped to the entire body.</em>
- <em><u>Left atrium, right atrium, left ventricle, right ventricle</u></em><em> not correspond to the order in which blood flows through the heart.</em>
- <em><u>Right ventricle, right atrium, pulmonary veins, lungs</u></em><em> not correspond to the flow of oxygen-poor blood.</em>
