Human Body Structure
There are six levels of organization when in comes to the human body. These structures include the following; chemical, cellular, tissue, organ, organ system & organisms. Below I have provided an example from our textbook that really helped:
As you can see, the higher levels of organization are built from the lower levels. This means cells combine to form tissue, tissue combines to form organs, organs combine to make organ systems and organ systems combine to form organisms.
If this is all still confusing to you I suggest watching this YouTube video: https://www.youtube.com/watch?v=epdpv7IOElw Question 2:

During my research, I found that brain damage is likely to occur within 5 minutes of no oxygen and in about 10 minutes death is likely to happen. Wow!
The nutrients help fuel our body and give us the energy to function. Nutrients are the beverages and food we consume daily. The most crucial is water. Depending on the environment and health of the body, a human may only be able to live without water for a short amount of time (3 days). Now the body is known to function several weeks without proteins, lipids, vitamins, minerals and carbohydrates. BODY TEMPATURE
The human body can respond to high temperatures by producing sweat and responds by shivering during colder (low) temperatures. Although, our bodies are capable of those responses our bodies can simply not handle the long exposures to hot or cold temperatures. For instance, heat strokes and hypothermia are examples to results of long exposures to extreme …show more content…
Most of the functions occurring in the human body are there to maintain homeostasis. For example, the body communicates through neural and hormonal control systems. The Receptor which responds to changes in the environment and sends info to the Control Center .The Control Center which determines the set point for each variable. “A set point is the physiological (function) value around which the normal range fluctuates” according to http://philschatz.com/anatomy-book/contents/m45989.html. (Sorry to just through the link in but it has helpful information and really breaks it down) The Control center also analyzes info coming in and sends out the right response. Lastly, the Effector (and remember to think muscle and glands every time this word is mentioned) is an organ that can cause change in a value. Homeostasis is maintained by negative feedback loops and, less continual positive feedback loops. Negative feedback loops work to stop an uncontrolled response to the stimulus. However, positive feedback loops build up the response until an end is
