61. List the survival needs for the human body.
Nutrients, Oxygen, Water, Stable Body Temperature, Appropriate Atmospheric Pressure,
Homeostasis
62. Why is it important to utilize the anatomical position?
It is important to use this because it provides a universal reference point for everyone around the
world in terms of locating organs and using landmarks to determine a particular area of the
human body.
63. What are the necessary life functions for the human body?
Maintaining Boundaries, Movement, Digestion, Responsiveness to Environment, Metabolism,
Excretion, Reproduction, and Growth.
64. Explain how two organ systems help the human body maintain homeostasis.
Ex. The Respiratory system takes in oxygen via the lungs and excretes excess carbon dioxide.
Oxygen travels from lungs into the blood and carbon dioxide travels from the blood into the lungs.
The blood circulates oxygen to all tissues and transports waste carbon dioxide to the lungs.
Together these two systems regulate a constant balance between oxygen and carbon dioxide in our
bodies.
65. List the 11 body systems below. Be sure to know the major organs and general functions of each.
Endocrine, Nervous, Integumentary, Reproductive, Respiratory, Cardiovascular, Urinary,
Digestive, Muscular, Skeletal, and Lymphatic.
66. Explain negative feedback and provide a couple examples of it in the human body. Draw a simple graph
that would illustrate negative feedback in the human body.
Negative feedback is a regulatory mechanism in which a 'stimulus' causes an opposite 'output' in
order to maintain an ideal level of whatever is being regulated; the response reverses a change in a
controlled condition. Examples include the maintenance of body temperature, blood oxygen and
carbon dioxide levels, and blood pH.
67. Explain positive feedback and provide a couple examples of it in the human body. Draw a simple graph
that would illustrate positive feedback in the human body.
Positive feedback occurs when the rate of a process increases as the concentration of the product
increases; the response strengthens the change in a controlled condition. Examples include normal
blood clotting and uterine contractions during labor.
68. Try labeling the following regional terms without using your notes. When you get as far as you can, then
use your notes to fill in any gaps.
