How are the alveoli in the lungs adapted for gas exchange?

The alveoli are adapted to make gas exchange in lungs happen easily and efficiently. they give the lungs a really big surface area. they have moist, thin walls (just one cell thick) they have a lot of tiny blood vessels called capillaries.

How are gases exchanged in alveoli explain with reference to partial pressure?

The change in partial pressure from the alveoli (high concentration) to the capillaries (low concentration) drives the oxygen into the tissue and the carbon dioxide into the blood (high concentration) from the tissues (low concentration), which is then returned to the lungs and exhaled.

What occurs in the alveoli?

The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out. Oxygen breathed in from the air passes through the alveoli and into the blood and travels to the tissues throughout the body.

Can pneumonia cause problems later in life?

Pneumonia may even be life-threatening and fatal in some cases. If you have lung cancer, you have an increased risk of developing pneumonia.

Do you ever fully recover from pneumonia?

How long can pneumonia stay in your lungs?

Pneumonia can hang around for about two weeks, or even longer in young children, elderly adults, and those who have weakened immune systems or ongoing illness like chronic obstructive pulmonary disease or asthma. Even healthy people may feel tired or weak for a month or more after their lungs clear up.

What are the signs and symptoms of pneumococcal pneumonia?

Common symptoms of pneumococcal pneumonia include high fever, excessive sweating and shaking chills, coughing, difficulty breathing, shortness of breath and chest pain. Certain symptoms, such as cough and fatigue, can appear without warning and may last for weeks, or longer.

What is the best treatment for pneumococcal pneumonia?

Doctors use antibiotics to treat pneumococcal disease. However, some pneumococcal bacteria have become resistant to certain antibiotics used to treat these infections. Available data show that pneumococcal bacteria are resistant to one or more antibiotics in 3 out of every 10 cases.

What antibiotics are used to treat pneumococcal pneumonia?

Conclusion. The recommended optimal in-hospital therapy for community-acquired pneumonia should continue to be a β-lactam antibiotic (penicillin, aminopenicillin, cefotaxime, or ceftriaxone) administered with a macrolide or a fluoroquinolone agent for adjunctive treatment of infection with potential atypical pathogens.

What Antibiotics treat pneumonia?

Several types of antibiotics are effective. Antibiotics that are used to treat walking pneumonia caused by Mycoplasma pneumoniae include: Macrolide antibiotics: Macrolide drugs are the preferred treatment for children and adults. Macrolides include azithromycin (Zithromax®) and clarithromycin (Biaxin®).

What is the first line treatment for pneumonia?

Children aged 2–59 months with severe pneumonia1 should be treated with parenteral ampicillin (or penicillin) and gentamicin as a first-line treatment. Ceftriaxone should be used as a second-line treatment in children with severe pneumonia having failed on the first-line treatment.
