Thermoregulation01:26

Thermoregulation

1.2K
The human body has a sophisticated thermoregulation system that employs negative feedback mechanisms to maintain an optimal core temperature. When the core temperature drops, peripheral and central thermoreceptors send signals to the hypothalamus, activating the heat-promoting center. This center triggers several responses aimed at increasing the core temperature. First, vasoconstriction reduces the flow of warm blood from internal organs to the skin so that the heat is not lost from the skin,...

Body Temperature01:25

Body Temperature

1.2K
The body's temperature, measured in degrees, is determined by the balance between heat production and dissipation to the surrounding environment. For instance, if exercising vigorously, the body will produce more heat, causing sweat and dissipating that heat. Despite extreme environmental conditions and physical exertion, the human temperature-control system maintains a constant core body temperature (the temperature of deep tissues, which are the tissues located beneath the skin and other...

Mechanisms of Heat Transfer II

3.4K
In convection, thermal energy is carried by the large-scale flow of matter. Ocean currents and large-scale atmospheric circulation, which result from the buoyancy of warm air and water, transfer hot air from the tropics toward the poles and cold air from the poles toward the tropics. The Earth’s rotation interacts with those flows, causing the observed eastward flow of air in the temperate zones. Convection dominates heat transfer by air, and the amount of available space for the airflow...

Responses to Heat and Cold Stress

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Mechanism of heat transfer

1.3K
Understanding heat transfer mechanisms is essential for understanding how our bodies maintain balance in different environmental conditions. When the environment is thermoneutral, the body is in a state of balance, neither using nor releasing energy to maintain its core temperature. However, when the environment is not thermoneutral, the body employs four heat transfer mechanisms to maintain homeostasis: conduction, convection, evaporation, and radiation. These mechanisms facilitate heat...

Mechanisms of Heat Transfer

430
Heat transfer between the human body and its environment occurs through four main mechanisms: conduction, convection, radiation, and evaporation.
Conduction, accounting for approximately 3% of body heat loss at rest, is the process of exchanging heat between molecules of two materials in direct contact. This can result in both heat loss and gain. For instance, when the body is submerged in water, which conducts heat 20 times more effectively than air, it can either lose or gain significant...

Area of Science:

  • Animal behavior
  • Equine science
  • Animal well-being

Background:

  • Rolling is a natural and essential behavior for equids, promoting well-being.
  • Intensive domestic environments limit opportunities for natural behaviors like rolling.
  • Providing suitable substrates is crucial for encouraging natural behaviors and enhancing animal welfare.

Purpose of the Study:

  • To evaluate the substrate preferences of horses (Equus caballus) and mules (E. asinus x E. caballus) for rolling.
  • To investigate the influence of rolling on thermoregulation in horses and mules post-exercise.
  • To understand species-specific differences in rolling behavior for improved animal management.

Main Methods:

  • Assessing rolling substrate preferences (sand, grass, manure) in 8 horses and 8 mules.
  • Measuring animal body temperature before and after rolling behavior.
  • Comparing substrate temperatures and their effect on post-exercise thermoregulation.

Main Results:

  • Horses showed a preference for rolling on grass, while mules preferred sand.
  • Both grass and sand were identified as cooler substrates compared to manure.
  • Rolling significantly reduced body temperature in both horses and mules after exercise.

Conclusions:

  • Rolling is vital for thermoregulation in horses and mules post-exercise.
  • Equids select cooler substrates (grass for horses, sand for mules) for efficient heat dissipation.
  • Individual preferences highlight the importance of tailored management strategies for horses and mules.
