16[blank_start]Chemical level[blank_end]: This is the very [blank_start]basic[blank_end] level of anatomy, like the letters of the alphabet.

18[blank_start]Tissue level[blank_end]: [blank_start]Tissues[blank_end] are groups of [blank_start]cells and the materials[blank_end] surrounding them that work together to perform a particular function, similar to the way words are put together to form sentences.
[blank_start]Organ level[blank_end]: At the [blank_start]organ level[blank_end], different types of [blank_start]tissues are joined together[blank_end].

19System level: A system that consists of related organs with a common function.

20A Receptor
(ie feedback system)- Ais a body structure that monitors changes in a controlled condition and sends input to a control center.
(example, the pancreas detects low blood glucose in the blood.) - Bin the body, for example, the brain, sets the range of values within which a controlled condition should be maintained
- Creverses a change in a controlled condition
- Dtends to strengthen or reinforce a change in one of the body’s controlled conditions
- Ais a body structure that monitors changes in a controlled condition and sends input to a control center.
21A Positive Feedback System
may be more then one right answer;- Atends to strengthen or reinforce a change in one of the body’s controlled conditions
- Bdoes not occur often in a controlled system
- Creverses a change in a controlled condition
- Dis a body structure that monitors changes in a controlled condition and sends input to a control center
- Ean example would be during childbirth contractions of the wall of the uterus force the baby’s head into the cervix, stretching the cervix. Stretch receptors detect this and send signals to the brain which releases the hormone oxytocin. Oxytocin makes the muscles of the uterus contract even harder, forcing the baby deeper into the cervix which causes even more stretching of the cervix.
- Atends to strengthen or reinforce a change in one of the body’s controlled conditions
22[blank_start]26[blank_end] different [blank_start]chemical elements[blank_end] normally are present in your body.
[blank_start]4[blank_end] of the elements, [blank_start]hydrogen (H)[blank_end] , carbon (C), [blank_start]oxygen (O)[blank_end], and nitrogen (N), are [blank_start]major[blank_end] elements, constituting about 96% of the body’s mass.- A26

23The body regulates its [blank_start]internal[blank_end] environment using [blank_start]two types[blank_end] of [blank_start]feedback systems[blank_end]. A feedback system, or [blank_start]feedback loop[blank_end], is a [blank_start]cycle of events[blank_end] in which a body [blank_start]condition[blank_end] is [blank_start]monitored[blank_end], evaluated, changed, and adjusted accordingly. Each factor being monitored, such as body temperature, blood pressure, or blood glucose level, is [blank_start]termed a controlled condition[blank_end]. Any disruption that changes a controlled condition is called a stimulus. For example, the body tightly regulates how much glucose is in the blood. If there is [blank_start]too little[blank_end], energy reactions may not take place efficiently. If there is [blank_start]too much[blank_end], glucose can damage blood vessels.
