Explanation

The lungs are located on either side of the breastbone in the chest cavity 

Explanation

Pneumonia is an infection that inflames the air sacs in one or both lungs.

The air sacs may fill with fluid or pus (purulent material), causing cough with phlegm or pus, fever, chills, and difficulty breathing.

Explanation

During respiration, organisms break down glucose to release energy, and carbon dioxide is produced as a byproduct.

Unlike photosynthesis, where oxygen is produced, respiration involves the release of carbon dioxide.

Explanation

 Hypoxia occurs when oxygen is insufficient at the tissue level to maintain adequate homeostasis, stemming from various causes such as hypoventilation.

Explanation

During an asthma attack, the type of blood cell that increases in the blood is eosinophils

Eosinophils are a type of white blood cell:

These cells play a significant role in the body's response to allergic reactions, including asthma, by releasing substances that can help combat allergens. 

Explanation

• Hypoxia usually results in Cyanotic skin color
• ***
• if a person has low oxygen in the blood then their skin color became bluish.
• Hypoxia is a Low level of Oxygen in the blood.

Explanation

• Features of Asthma include: Inflammation of the upper airways
• ***
•  As mentioned earlier, the three basic features of asthma are
• airway inflammation,
• airways hyperresponsiveness,
• and mucous hypersecretion.
• These three features lead to bronchoconstriction and airflow obstruction, which manifest as wheezing and dyspnea in the patient with asthma.
