This is the only homework on human systems, excluding reproduction.  You will find the text reading for this on pp 8 to 11 and in your notes. We will take only one week to cover...if all goes to plan.  Next week we will do reproduction (may begin this week) and at the end of the two weeks we will have a test on all human systems.

Question #1:
Finding shelter, avoiding predators, and obtaining food are most closely related to the ability of an animal to:
          1) use structures adapted for movement
          2) increase the rate of mitosis
          3) transport carbon dioxide to cells
          4) excrete waste products of metabolism

Question #2: A similarity betwen the nervous system and the hormone-secreting system in humans is that they both
          1) are composed of the same type of cells
          2) are composed of many glands
          3) help to maintain homeostasis
          4) secrete chemicals directly into the blood

Question #3: Inhaling carbon monoxide reduces the ability of red blood cells to carry oxygen.  This can lead to brain damage.  Which three systems of the body interact in this situation?
          1) digestive, respiratory, and circulatory
          2) immune, circulatory, and digestive
          3) respiratory, circulatory, and nervous
          4) excretory, nervous, and respiratory

Question #4: The activity of all human body systems is coordinated by:
          1) the secretion of hormones and the nervous
              system
          2) the interaction of nerve impulses with the
              excretory system
          3) the movement of digested food by the
              circulatory system
          4) the secretion of hormones and the circulatory
              system

Question #5: Two organs are considered to be a part of the same body system if the organs
          1) are located next to each other
          2) work independently of each other
          3) work together to carry out life functions
          4) are made up of cells with organelles

Queston #6: During exercise, the heart beats faster to
          1) carry digestive juices to the small intestine
          2) provide muscles with additional oxygen
          3) lower the blood pressure
          4) digest more food

Question #7: The circulatory system helps to maintain homeostasis by interacting with the
          1) nervous system and transporting chemicals
             produced by nerve cells from one cell to
             another
          2) respiratory system and producing oxygen for
             gas exchange
          3) digestive system by removing undigested food
             from the stomach
          4) excretory system in helping to regulate body
             temperature through sweating

Question #8: Before it can be used by individual cells, food must be broken down and distributed throughout the humnan body.  Name the two systems that must interact to accomplish this.

Question #9: Your finger brushes against a hot stove and you quickly pull away.  Identify which two human body systems work together to respond to this painful stimulus  and explain the specific interaction between them.

Question #10 Describe how the chemical composition and genetic information of humans resembles the chemical composition and genetic informatin of other organisms.
