Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

11.6K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Regulation of Water Intake01:25

Regulation of Water Intake

492
Osmolality refers to the number of solute particles per kilogram of solvent in a solution. Plasma osmolality specifically indicates the total number of solute particles per kilogram of water in blood plasma. This value reflects the body's hydration status and is tightly regulated through mechanisms controlling water intake and output. While water consumption is a conscious decision, the body has intrinsic regulatory systems to maintain fluid balance. Dehydration, a state of water deficit...

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

934
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...

Key Elements for Plant Nutrition

18.7K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Defense Mechanism Against Infection01:26

Defense Mechanism Against Infection

6.5K
Natural flora, body system defenses, and inflammation are natural barriers of the body against infectious agents regardless of previous exposure. Normal floras of the human body refer to the microbial population that colonizes the skin and mucous membranes.
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...

Area of Science:

  • Immunology
  • Physiology
  • Nutrition Science

Background:

  • Dehydration can occur in adults from various conditions like heat illness and infections, leading to fluid, electrolyte, and energy (FEE) deficits.
  • This deficit impacts immune function at cellular and molecular levels, even without diarrhea.
  • Essential micronutrients like vitamins C and E, copper, zinc, and selenium also play a vital role in immune support and antioxidant activity.

Purpose of the Study:

  • To examine the impact of dehydration on immune function.
  • To highlight the role of hydration and micronutrients in immune response.
  • To emphasize the importance of fluid and FEE supplementation during illness.

Main Methods:

  • The study reviews physiological mechanisms of immune response to dehydration.
  • It discusses the role of aquaporins (AQPs) in immune cell function and permeability.
  • It examines the contribution of micronutrients to immune health.

Main Results:

  • Fluid deficits from dehydration impair cellular and molecular immune functions.
  • Aquaporins (AQPs) are critical for immune cell communication and mobility.
  • Nutrient deficiencies exacerbate immune vulnerability.

Conclusions:

  • Dehydration, even without diarrhea, compromises immunity and delays recovery.
  • Adequate fluid, electrolyte, and energy (FEE) intake is essential for immune resilience.
  • Prioritizing hydration and nutrition is critical in healthcare and daily life.
