QUESTION
Research the topic of blood pressure, focusing on how homeostasis is maintained for the condition. Write an essay summarizing your research. Be sure to include the following: What factors can shift this condition requiring feedback and homeostatic processes? Identify the organ systems that are involved in the homeostatic processes. What kind of feedback, positive or negative, is used to maintain homeostasis? For the feedback loop, identify the stimulus, receptor, integrating center, effector, and response. Identify any other strategies, such as drug therapies, exercise etc., can be used to help maintain balance in this condition.
BLOOD PRESSURE
Blood pressure entails the pressure that blood imparts within the circulatory system.
Often, blood pressure is measured during clinical diagnosis because it is closely associated with
the force and heartbeat rate and elasticity within the artery walls. On the other hand,
homeostasis refers to the body’s ability to maintain internal stability in relation to
environmental changes (Burlando, Blanchini & Giordano 2019).
There are five factors that influence blood flow or rather blood pressure. These factors
are cardiac output, the volume of blood, compliance, blood viscosity, and the elasticity of blood
vessel walls. Changes in these factors beyond certain levels prompt homeostasis processes to beinitiated. External factors such as a change in temperature, exercises, and change in emotions affect these factors which in turn call for feedback and homeostatic processes.
Two major organ systems are involved in homeostasis processes. These organs are the
nervous and endocrine systems. The two organs control homeostasis processes since they are
the ones coordinating how the body systems function. Also, they are responsible for initiating
both positive and negative feedback loops (Burlando, Blanchini & Giordano 2019).
The kind of feedback employed in maintaining homeostasis is negative feedback.
Negative feedback loops have the ability to increase or reducing a stimulus within an
organism’s body.
In the negative feedback loop, the stimulus is body temperature. The receptors are
thermo-receptors which note changes within an organism’s body temperature while the control
center is the hypothalamus. It controls different effectors that act in response to changes in
body temperature. Regarding effectors, there are a number of effectors that are managed by the hypothalamus. An example of an effector is blood vessels that are in proximity to the skin
constrict. In case of an increase in temperature, they reduce the flow of blood in an organism’s
body. The skeletal muscle is also an example of an effector. They usually react by contracting
regularly in response to a reduction in temperature within an organism’s body. When an
organism shiver, heat is generated thus increasing temperature in the body (Burlando, Blanchini
& Giordano 2019).
Some of the strategies that can be used to maintain balance in this condition comprise;
maintaining a healthy weight, reducing alcohol intake, managing anger and stress, drug
therapies and carrying out regular exercises (Burlando, Blanchini & Giordano 2019).
In conclusion, apart from homeostasis, the cardiovascular system is also responsible for
controlling blood pressure. It is the one responsible for the transportation of hormones that help
in the homeostasis process. As evident, homeostatic plays a critical role in helping the body
maintain balance.
