Factors Affecting Pulmonary Ventilation01:19

Factors Affecting Pulmonary Ventilation

1.4K
Besides the pressure difference between the external environment and the lungs, the airflow rate and ease of pulmonary ventilation are also influenced by three other factors: surface tension of the fluid in the alveoli, compliance of the lungs, and airway resistance.
Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...

Dimensions of Health and Illness

7.4K
The factors influencing the health-illness continuum can be internal or external and may or may not be under conscious control. They are related to the following eight human dimensions, and each dimension is interrelated to one other.

Lifestyle Factors and Health

56
Lifestyle factors play a critical role in maintaining overall health and preventing chronic diseases. Key elements, such as regular physical activity, a nutritious diet, and abstinence from smoking, can significantly enhance physical, mental, and emotional well-being while reducing the risk of several life-threatening conditions.
Benefits of Physical Activity
Physical activity, whether through structured exercise or casual activities like walking, biking, or dancing, is a cornerstone of a...

Types of Toxins01:36

Types of Toxins

1.7K
Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.
Environmental pollutants like...

Threats to Biodiversity01:50

Threats to Biodiversity

22.3K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

Area of Science:

  • Environmental Science
  • Public Health
  • Ecosystem Services

Background:

  • Limited land resources necessitate careful planning to balance food security, health, and ecosystem functions.
  • Ecosystem service assessments guide land-use decisions but often overlook air quality impacts, a major environmental health risk.

Purpose of the Study:

  • To estimate and value the air quality health effects of land-use policies and trends in the U.S. until 2051.
  • To compare the significance of air quality impacts with carbon sequestration and economic returns in land-use decision-making.

Main Methods:

  • Integrated assessment modeling to quantify land-use impacts on air quality.
  • Valuation of health outcomes associated with air pollution from land use.
  • Economic analysis of land-use policies considering multiple ecosystem services.

Main Results:

  • Air quality health effects are a primary consideration in land-use decisions, often exceeding the value of carbon sequestration and economic returns.
  • Policies appearing beneficial without air quality assessment can be detrimental when these impacts are included.
  • Agricultural and forest emissions significantly influence land-use-driven air quality, while reduced deforestation remains broadly beneficial.

Conclusions:

  • Accurate land-use decision-making requires the explicit inclusion of air quality and its associated health impacts.
  • Failure to account for air quality leads to incomplete and potentially flawed assessments of land-use policies.
  • Integrating air quality into land-use planning is essential for maximizing societal well-being and environmental health.
