What are two ways that reflex reactions help maintain Homoeostasis in the human body?
Homeostasis (autonomic reflexes) is maintained by reflexes such as heart rate, breathing rate, blood pressure, and digestion.
What describes homeostasis?
Homeostasis, as currently defined, is a self-regulating process by which biological systems maintain stability while adjusting to changing external conditions.
What reflex helps maintain balance?
Crossed-Extensor Reflex. In this reflex, as withdrawal from the damaging stimulus occurs in the ipsilateral leg, extension occurs in the contralateral leg as a way of maintaining balance.
What are the functions of reflexes?
Reflexes protect your body from things that can harm it. For example, if you put your hand on a hot stove, a reflex causes you to immediately remove your hand before a "Hey, this is hot!" message even gets to your brain.
How do humans maintain homeostasis?
Eating, drinking, even simple breathing can introduce indigestible and even dangerous substances into the body. The body maintains homeostasis by eliminating these substances through the urinary and digestive systems.
How homeostasis is maintained?
Homeostasis is maintained by a series of control mechanisms functioning at the organ, tissue or cellular level. These control mechanisms include substrate supply, activation or inhibition of individual enzymes and receptors, synthesis and degradation of enzymes, and compartmentalization.
How are reflexes useful to humans?
Reflexes protect your body from things that can harm it. For example, if you put your hand on a hot stove, a reflex causes you to immediately remove your hand before a "Hey, this is hot!" message even gets to your brain.
Why are reflexes important to maintaining homeostasis?
Recall from module one the importance of homeostasis. Reflexes are the mechanism whereby the body is able to sense changes and respond appropriately in order to maintain homeostasis. Reflexes take place automatically and unconsciously for good reason.
Why are reflex actions important to the human body?
Reflexes perform many essential jobs for our central nervous system. They protect us from danger, they help us move our body and they help us to see. They are intended to help prevent injury to our bodies, but they are not always entirely effective in totally preventing injuries.
What are two examples of homeostasis in the human body?
Some examples of the systems/purposes which work to maintain homeostasis include: the regulation of temperature, maintaining healthy blood pressure, maintaining calcium levels, regulating water levels, defending against viruses and bacteria.
What is an example of maintaining homeostasis?
Body temperature control in humans is one of the most familiar examples of homeostasis. Normal body temperature hovers around 37 °C (98.6 °F), but a number of factors can affect this value, including exposure to the elements, hormones, metabolic rate, and disease, leading to excessively high or low body temperatures.
What are two ways your body maintains homeostasis?
Eating, drinking, even simple breathing can introduce indigestible and even dangerous substances into the body. The body maintains homeostasis by eliminating these substances through the urinary and digestive systems.
What are 3 examples of homeostasis?
Examples include thermoregulation, blood glucose regulation, baroreflex in blood pressure, calcium homeostasis, potassium homeostasis, and osmoregulation.
How do reflex actions help to protect our bodies from damage?
Reflexes protect your body from things that can harm it. For example, if you put your hand on a hot stove, a reflex causes you to immediately remove your hand before a "Hey, this is hot!" message even gets to your brain.
What are the two main advantages of a reflex action and why are they important?
Reflex actions allow a quick response to danger. One of the main advantages of reflex actions is that they occur rapidly and allow you to avoid danger. So, the choice that is not an advantage of having reflex actions is reflex actions prevent a person from feeling pain.
How are reflexes homeostatic?
Reflexes are the mechanism whereby the body is able to sense changes and respond appropriately in order to maintain homeostasis. Reflexes take place automatically and unconsciously for good reason.
What are reflex actions give two examples explain the function of any two of its parts?
Reflex action is defined as an unconscious and involuntary response of effectors to a stimulus. Example on touching a hot object stimulus we immediately remove our hand from it. Other example from daily life are watering of mouth on seeing food sneezing blinking of eyes and yawning.
What are 3 reflexes in humans?
Types of human reflexes
- Biceps reflex (C5, C6)
- Brachioradialis reflex (C5, C6, C7)
- Extensor digitorum reflex (C6, C7)
- Triceps reflex (C6, C7, C8)
- Patellar reflex or knee-jerk reflex (L2, L3, L4)
- Ankle jerk reflex (Achilles reflex) (S1, S2)
How does the human body maintain homeostasis?
So how does your body maintain homeostasis? The regulation of your internal environment is done primarily through negative feedback. Negative feedback is a response to a stimulus that keeps a variable close to a set value (Figure below).
What are the ways to maintain homeostasis?
1 Answer
- Temperature. The body must maintain a relatively constant temperature. …
- Glucose. The body must regulate glucose levels to stay healthy. …
- Toxins. Toxins in the blood can disrupt the body's homeostasis. …
- Blood Pressure. The body must maintain healthy levels of blood pressure. …
- pH.

How is homeostasis maintained in the human body?
Homeostasis is generally maintained by a negative feedback loop that includes a stimulus , sensor , control centre , and effector . Negative feedback serves to reduce an excessive response and to keep a variable within the normal range. Negative feedback loops control body temperature and the blood glucose level.
What are 3 examples of maintaining homeostasis?
Some examples of the systems/purposes which work to maintain homeostasis include: the regulation of temperature, maintaining healthy blood pressure, maintaining calcium levels, regulating water levels, defending against viruses and bacteria.
What are 4 ways the body maintains homeostasis?
1 Answer
- Temperature. The body must maintain a relatively constant temperature. …
- Glucose. The body must regulate glucose levels to stay healthy. …
- Toxins. Toxins in the blood can disrupt the body's homeostasis. …

Which of these help maintain homeostasis in the body?
The endocrine and central nervous systems are the major control systems for regulating homeostasis (Tortora and Anagnostakos, 2003) (Fig 2). The endocrine system consists of a series of glands that secrete chemical regulators (hormones).
What are the 2 examples of homeostasis that occur to human body?
Other Examples of Homeostasis
- Blood glucose homeostasis.
- Blood oxygen content homeostasis.
- Extracellular fluid pH homeostasis.
- Plasma ionized calcium homeostasis.
- Arterial blood pressure homeostasis.
- Core body temperature homeostasis.
- The volume of body water homeostasis.
- Extracellular sodium concentration homeostasis.
How might reflexes be useful in maintaining homeostasis?
Reflexes maintain homeostasis (autonomic reflexes) – heart rate, breathing rate, blood pressure, and digestion. b. Reflexes also carry out the automatic action of swallowing, sneezing, coughing, and vomiting.
How does reflex action help in daily life of human being?
It helps organisms to quickly adapt to an adverse circumstance that could have the potential to cause bodily harm or even death. Pulling our hands away immediately after touching a hot or cold object is a classic example of a reflex action.
How do reflex actions work in humans?
Many reflexes start at the muscle or skin and go to the spinal cord. When the action potential reaches the nerve ending, the signal is transferred to another neuron, such as an interneuron or motor neuron. The action potential then travels outside the spinal cord to a muscle.
How do reflexes help us survive?
Reflexes are kind of like safety features for survival that allow us to move in response to something in the environment. Reflexes can act to protect you in many ways, including removing your hand from a hot or sharp object, or ducking when a loud and sudden sound occurs. These fast actions are reflex responses!
