Role of Water in Human Biology01:27

Role of Water in Human Biology

12.2K
Water is the one of the most significant components of the human body; it plays a crucial role in several physiological activities because of its unique physicochemical properties. Importantly, it helps to regulate body temperature and is the chief component of several body fluids.
Water's Solvent Properties
Since water is a polar molecule with slightly positive and slightly negative charges, ions and polar molecules can readily dissolve in it. Therefore, it is referred to as a solvent, a...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

13.1K
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...

Quality of Water01:19

Quality of Water

418
In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...

Disorder of Water Balance01:29

Disorder of Water Balance

2.2K
Water balance disorders are medical conditions that occur when there is a deviation from the body's water volume or osmolarity, disrupting normal homeostasis and leading todehydration, hypotonic hydration, hyperhydration, edema, or water intoxication.
Dehydration
Dehydration occurs when the body loses fluids (particularly water).
Causes:
The major causes of dehydration include excessive sweating, fever, vomiting, diarrhea, and diuresis.
Signs and Symptoms:
Symptoms primarily include intense...

Aquaporins01:25

Aquaporins

5.9K
Aquaporins or AQPs are a family of integral membrane proteins whose primary function is to transport water, while some called aquaglyceroporins also transport glycerol. In addition, aquaporins have also been suspected to be involved in transporting volatile substances, such as carbon dioxide and ammonia, across membranes. Such AQPs that act as gas channels are often highly expressed in cells involved in the gaseous exchange, such as red blood cells, epithelial cells, and pulmonary capillaries.

Regulation of Water Intake01:25

Regulation of Water Intake

2.4K
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...

Summary

The COVID-19 pandemic increases water demand and worsens water quality, posing challenges for water management. Addressing these impacts requires interdisciplinary collaboration and new strategies for water resource challenges.

Area of Science:

  • Environmental Science
  • Public Health
  • Water Resource Management

Background:

  • The COVID-19 pandemic, caused by SARS-CoV-2, has had profound global impacts since its emergence in December 2019.
  • The disease has spread worldwide, resulting in significant mortality and widespread societal disruption.

Discussion:

  • COVID-19 control measures, such as increased hygiene practices, elevate water demand.
  • These measures can also degrade water quality due to increased pollutant loads and altered treatment processes.
  • The pandemic exacerbates existing water resource challenges, including those from global climate change.

Key Insights:

  • Efforts to contain COVID-19 directly impact water resources by increasing demand and reducing quality.
  • Water planning and management face significant new challenges due to the pandemic's effects.
