- oxygen.
- water.
- stable body temperature.

Does every organ play a direct role in excretion?
Excretion is the process of removing wastes, or excreta (ek-skre′tah), from the body. Every organ system plays a direct role in excretion.
What is appropriate atmospheric pressure?
The standard, or near-average, atmospheric pressure at sea level on the Earth is 1013.25 millibars, or about 14.7 pounds per square inch.
Which of the following is true of positive feedback mechanisms?
Which of the following is true of positive feedback mechanisms? The result or response enhances the original stimulus, and the response is accelerated. Which of the following is an example of positive feedback? Release of oxytocin to increase the strength of labor contractions.
What nutrition does the human body need for survival quizlet?
The six essential nutrients include carbohydrates, protein, fat, vitamins, minerals and water. There are three macronutrients required by humans: carbohydrates (sugar), lipids (fats), and proteins. Each of these macronutrients provides energy in the form of calories.
What are survival needs?
Survival Needs To sustain human life, certain physiological needs include air, water, food, shelter, sanitation, touch, sleep and personal space.
How does the excretory system maintain homeostasis?
The excretory system works with the endocrine system to help maintain homeostasis. Chemical messengers called hormones signal the kidneys to filter more or less water or salt, depending on the levels of water and salt in the body. For example, when you sweat a lot the water content of your blood can drop.
Why do we need the excretory system?
The excretory system is important because it helps the body eliminate metabolic waste, maintain a balance of salt and water, and control blood…
What is required to sustain human life?
We must have food, water, air, and shelter to survive. If any one of these basic needs is not met, then humans cannot survive.
Why is heat necessary for survival?
In physical science, heat is important to all aspects of life, especially plants and mammals. Plant life relies on heat, among other things, to survive as well. Heat is a result of energy, which can be beneficial as well as dangerous.
What is true of positive feedback?
Positive feedback occurs to increase the change or output: the result of a reaction is amplified to make it occur more quickly. Some examples of positive feedback are contractions in child birth and the ripening of fruit; negative feedback examples include the regulation of blood glucose levels and osmoregulation.
How does positive feedback maintain homeostasis?
Positive feedback is a mechanism in which an output is enhanced in order to maintain homeostasis. A positive feedback example is blood platelet accumulation and aggregation, which in turn causes blood clotting in response to an injury of the blood vessels.
Which is an example of not sufficient survival factors?
Atmospheric pressure is an example of how the mere presence of survival factors is not sufficient to maintain life. Too much or too little may be equally harmful. For example, excessive oxygen is toxid to body cells. The reproductive system __________.
How many basic survival needs do you need?
But there are six basic survival needs that, if met, should help you stay alive longer than anyone else. Obviously there will be others, but to physically sustain your body, you need to plan for five of these (while the 6th is not really as basic as the rest, but just as critical).
Why do we need fresh water for survival?
The next crucial survival need is for fresh water. About 60% of the human body consists of water. It’s a needed component for every cell in our bodies and it acts as a joint lubricant, helps to flush waste and toxins, and to balance body temperature via respiration and perspiration.
What are the 5 basic needs of life?
The 5 Basic Survival Needs 1 Need for Oxygen/Air to Breathe. 2 Need for Shelter/Warmth. 3 Need for H2O/Water. 4 Need for Food. 5 Need for Sleep.
