To stay in a state of equilibrium, the body must remain in something called homeostasis this
process controls and maintains the body's internal conditions, which may be affected by
internal and external factors if the body moves around in these ranges, the body
begins to miss function .Homeostasis is made up of positive and negative feedback
loops. A positive feedback loop within homeostasis means that a receptor has to detect a
change within a stimulus and then, in turn, that affect her increases the stimulus to increase
the changes in the environment in short the positive feedback loop’s main aim is the process
of moving the system away from equilibrium in the long-term positive feedback Loops can
create unstable scenarios within the body however they also provide a useful service for
example when a woman is in labour the contractions are an example of a positive feedback
loop. Alternatively, a negative feedback loop involves a receptor detecting a difference
between internal stimulus and the effect of reacting; therefore, decreasing the stimulus in a
short negative feedback loop allows the system to return there to equilibrium within the body.
The negative feedback the receptor plays a large role in detecting turn up or external
changes to the environment; this information is then sent back to the brain, which they're and
reacts in a way to return the body to normal an example of this could be making hairs stand
up on the back of arms when the body is cold to trap the warm and to the skin.

Thermoregulation
Within homeostasis, thermoregulation is crucial. Due to its ability to control the body's
internal temperature and react, I respond to internal and external changes in temperature
around the body. The internal temperature in the body should be maintained at around 36-37
degrees Celsius, and it is important to keep the body at this temperature enzymes and
different cell functions work the best at this temperature. For example, a linked to actions of
enzymes if the body drops below its ideal temperature, then the enzymes will begin to slow
down and not be as active, which could leave waste products behind or specific molecules
not broken down, and this can lead to further problems such as things in digestion as well as
breaking down waste products that are produced within the body. Key components in
controlling thermoregulation within the body cells, such as receptors and effectors and a
coordinator, are usually in the central nervous system. The receptors play a large role in
detecting the original change in temperature a type of receptor called a thermoreceptor is in
layers of the skin and are specialised to sense temperature changes and relay the
,messages back to the thermae regulators within the central nervous system. There are two
types of them are regulators within the skin, the ones that detect an increase in temperature
and ones that detect a decrease in temperature; the ones that detect an increase in
temperature are a lot closest to the surface of the skin, whereas the others are found deep in
the dermis of the skin. The amount of these receptors and how close or far away they are
from the top of the skin mean that some regions of the body are more sensitive to changes
in temperature. However, in a general statement, we are more sensitive to heat than the
cold, which is important because we can burn ourselves with hot substances. The brain
needs to register the temperature change before further damage to the skin occurs.

The role of the hypothalamus within thermoregulation
The role of the hypothalamus is interlinked to the control
of temperature within the body; this is due to the location
of the hypothalamus being next to the thermoregulatory
controlling centre of the brain, and four plays a large role
in controlling external and internal body temperature.
The hypothalamus is divided into two sections controlling
heat gain and one controlling heat loss. When the body
is too hot, the heat loss section is activated, and this
assists in cooling down the body versus when the body
is too cold. The warming up centre is activated, and this
helps warm the body up to the correct temperature these
two sections of the hypothalamus get the information from the receptors within the skin as
well as thermoreceptors within each section as well. The thermoreceptors within the
hypothalamus do not detect external changes; however, they do detect internal changes by
measuring the temperature of the blood; once this measurement has been taken and if any
changes need to be made, the specific receptors send nerve pulses to that effect as within
the hypothalamus to help return the body to thermoregulation. Examples of effectors can be
sweat glands, skeletal muscles, and other glands around the body. These effectors are
crucial in helping the body heat or cool down during thermoregulation.
Examples of negative and positive feedback loops within thermoregulation. When
thermoreceptors in the skin detect an increase in temperature, the hypothalamus sends a
nerve impulse to the effectors to start the cooling down mechanism. The body cools down by
relaxing the muscles within the walls of arterioles, which allows for vasodilation and,
therefore, an increased blood flow to the capillaries on the skin's surface, which leads to
increased heat loss during the same time, hair erector muscles will also relax. This makes
them lie flat, which prevents them from trapping any heat. Sweat glands produce more
sweat. This is because heat is absorbed by sweat and is carried away from the body when
the sweat evaporates. When thermoreceptors in the skin detect a decrease in temperature,
the hypothalamus sends a nerve impulse to the effectors to induce a heating mechanism. A
way in which the body increases its temperature is by contracting the muscles within the
walls of arterioles which allows for vasoconstriction. This results in a decreased blood flow to
the capillaries on the skin's surface, leading to decreased heat loss. The erector muscles will
, contract. This makes them stand up, which allows them to trap heat. Sweat glands produce
less or no sweat. There is less sweat to absorb heat, allowing the body to retain more heat.

Hormones
Hormones send signals around the body to effectors; they are chemical messengers vs
nerve impulses which are electrical in messengers. Hormones are a lot slower than nervous
impulses; however, they can trigger long-term changes within the body; for example, an
increase in certain hormones during puberty can make long-term changes. For example, the
growth of body hair and growth spurts are caused by certain hormones; they are transported
through the blood, which helps them reach multiple different tissues and organs.
Glands
Glands are organs that secrete specific types of hormones. These are known as endocrine
glands to create the hormones directly into the blood examples of these are the thyroid and
pituitary glands; exocrine glands are glands that contain ducks, and these transport any of
the secretions to the surface, for example, salivary glands and sweat glands that are in the
liver and the pancreas can perform both endocrine and exocrine functions.

The role of the hypothalamus
Hypothalamus is located in the brain above the pituitary gland and is the control centre for
most basic functions in the body; it communicates with the autonomic nervous system and
helps control blood pressure, blood temperature, breathing, digestion, and sleep cycle. It
also is closely linked to the pituitary gland. It helps release different women's and
Productions of them. The hypothalamus is often the link between the nervous and endocrine
systems; the hypothalamus helps control the hormone release within the pituitary gland and
sends signals through the nervous system to the pituitary gland. the hypothalamus is
involved in integrating several different hormones, one of which is oxytocin which helps
control a number of the body's functions such as body temperature, the release of
breastmilk, and sleep cycles; another primary hormone that is secreted by the hypothalamus
is this hormone triggers the thyroid-stimulating hormone which then interns helps release
hormones from the thyroid. (3)
