How do human bodies maintain homeostasis in cold weather?
blood vessels constrict, pores close, metabolism increases
How does active and passive transport help maintain homeostasis?
Active and passive transport help to maintain homeostasis because they transport fluid/water/materials across the plasmalemma (cell membrane). All of these materials need to exist in certain ratios for the cell to function properly. All levels of organization in the body (chemical/molecular level, cellular level, tissue level, organ level, organ system level) are dependent on one another. Example: Heart functioning normally requires coordinated contractions in the adjacent muscle cells of cardiac muscle tissue to produce a heartbeat. Once that occurs, the internal anatomy of the heart allows it to act as a pump and every time it contracts, blood is pushed into the circulatory system. The heart, blood, and circulatory system then from the cardiovascular system (which is an organ system). Damage at any of the levels can affect the entire system and something that affects the system will end up affecting all components. Ex: Chemical change in heart muscle cells can cause abnormal contractions or even stop the heartbeat alltogether. So, in order for those chemicals/materials to stay the same, active and passive transport are needed to keep them at stable levels inside and outside the cell membrane. When all the systems are functioning normally, the characteristics of the internal environment will be relatively stable at all levels. This is known as homeostasis. Failure to maintain homeostasis can cause disease. Hopefully this answers your question!
How is homeostasis maintained by the muscular system?
Homeostasis refers to the regulation and survival of cell systems within an organisms. There are many systems in the human body that contribute to maintaining the various biological levels necessary for homeostasis. Homeostasis needs may vary between different species.The muscular system consists of cardiac, skeletal and smooth tissues. Muscles are able to move because of the skeletal tissue attached to bones, explains Oswego City School District Regents Exam Prep Center. The skeletal muscles receive movement signals from the motor neurons in the nervous system. The signals serve as impulses that tell the muscles what type of movement is necessary. Similarly, the circulatory system helps deliver oxygen to the muscles. Oxygen is necessary for cellular respiration in the muscles. Cellular respiration provides muscles with the appropriate amount of energy for the muscles to move efficiently and keep up with the demands of the human body.Hope it helped:)
Two body systems that work together to maintain Homeostasis?
All your body's systems work together to maintain homeostasis, but an example of two would be the circulatory system and the respiratory system. The circulatory system to exchange waste and gasses, as well as bringing fresh oxygen to your tissues. The circulatory system will bring the gas waste to your respiratory system (lungs) to be expelled. You also breathe in fresh O2 into your lungs, and through diffusion from the alveoli to the capillaries, your circulatory system takes the O2 back to the tissues. This maintains pH homeostasis throughout your body, and it'll keep you alive.
What is Homeostasis? please someone explain?
Homeostasis is the property of a system in which variables are regulated so that internal conditions remain stable and relatively constant. Examples of homeostasis include the regulation of temperature and the balance between acidity and alkalinity (pH). It is a process that maintains the stability of the human body's internal environment in response to changes in external conditions. So it's a system that keeps the body balanced (Heat, PH, glucose, water etcetc)
What are the four things that cells do to maintain homeostasis?
Homeostasisis the maintenance of a constant internal state in a changing enviorment .In order to survive , [1]yours cells need to be able to obtain and use energy,[2]make new cells,[3]exchange materials,[4]and eliminate wastes .What cells doRegulate intracellular ion control (e.g. maintain very specific [Ca^2+] levels)Regulate extracelluar to intracellular ion transport. E.g. for maintaining water and blood pressure via the kidneys.Regulate metabolism, for temperature control (e.g. in brown adipose tissue).Regulate transcription and translation, for hormone release (through negative feedback).How do cells maintain homeostasis?
What are some examples of homeostasis in animals?
A good example is the jackrabbit (please google image); the regulation of blood flow through its ears helps maintain a constant body temperature by adjusting heat exchange with the surrounding air.
Using the key choices, correctly identify the survival needs to correspond to the following description.?
1. C 2. D, B 3. E 4. D 5. E, C 6. A I don't know if you're allowed to answer with more than one letter, but a few of them overlap. Here's my reasoning on the above: 1: kind of self-explanatory. 2: oxygen is obviously vital for function to the respiratory system, but a lack of pressure (which limits the amount of O2 you're exposed to) can also kill you. 3: Again, obvious. 4: mitochondria produce energy via oxidative phosphorylation, which uses oxygen. Water is produced, but not used in this process. 5: You need both water and nutrients to produce a bodily fluid. Without nutrients (in some form) it'd just be water, and without water it wouldn't be a liquid. 6: The reason the body has homeostasis.
What is homeostasis? What are 3 examples?
constant condition of properties.Homeostasis is happening constantly in our bodies. We eat, sweat, drink, dance, eat some more, have salty fries, and yet our body composition remains almost the same. If someone were to draw your blood on ten different days of a month, the level of glucose, sodium, red blood cells and other blood components would be pretty much constant, regardless of your behavior (assuming fasting before drawing blood, of course).No matter how much water you drink, your body doesn't swell up like a balloon if you drink tons, and it doesn't shrivel like a raisin if you drink very little. Have you ever wondered about this? Somehow, our bodies know how much fluid we need to keep, and then maintain a constant level regardless of how much water we drink.This maintenance of body size is an example of homeostasis. And we don't even have to think about it for this to happen! Aren't our bodies amazing?There are several other examples of homeostasis. For example, our concentration of salts and glucose (sugar) is constant; our body temperature is usually around 37 degrees Celsius (98.6 degrees Fahrenheit); the amount of blood in our bodies is about 5 liters, the osmolarity (number of solutes) of our blood remains about 300mOsm. The normal value of a physiological variable is called its set point.Study.com
