Essential Question Bell Ringer

• Why is it important that an organ system interact
  with other organ systems?

Each organ system is part of the whole living
organism. The specialization of each system
requires that it rely on and interact with other
systems so that the organism can function
properly and survive. A single system cannot by
itself ensure proper function and survival of an
organism.

Write and answer the following question in your
journal.
1. What are some of the interactions that occur
among the lymph, circulatory, and immune systems
when a person is fighting an infection like the
flu?
All three systems are involved in protecting the
organism from infection and disease. The lymph
system produces lymphocytes to fight infection
that may be found in the blood stream. It also
collects and transports fluids around the tissues
back to the veins of the circulatory system. In
the circulatory system, white blood cells fight
infection and protect the body against foreign
materials. It works with the lymph system to
stabilize the concentration of fluids in the body
and helps transport the lymphocytes to the site
of the infection. The immune system includes
parts of the lymph system and works with the
lymph and circulatory systems by fighting
infection through production of T-cells and
antibodies.

Write and answer the following question in your
journal.

• 2. What interactions must occur among the
  digestive, nervous, and lymph systems to enable
  digested food (biomolecules) to be transported
  from the digestive system to the cells of the
  body?

The digestive system must break down the foods
that are eaten by an organism into smaller
particles (or biomolecules) such as
carbohydrates, lipids, and amino acids. Fats are
emulsified by the bile that is produced by the
liver and then transported to the circulatory
system through the lymph system for further
digestion. The nervous system has control of the
processes and functions of the digestive and
lymph systems.

Write and answer the following question in your
journal.

• 3. When a runner completes a 10K race, she is
  breathing heavily, sweating profusely, and her
  heart rate is rapid.
• What systems are involved in causing these
  changes in her body systems? How do these
  systems interact to allow her to complete the
  race?

The three systems that are involved are the
integumentary, circulatory, and nervous systems.
Their interactions enable her to run, and with
proper training, to run long distances like a 10K
race. The integumentary system is working with
the circulatory system to rid the body of liquid
waste products that are formed in the muscles of
the bodythe circulatory system transports the
waste products internally and the integumentary
system excretes them through the skins glands as
sweat. The sweat has a secondary function in
that, as it evaporates, it helps cool and control
the temperature of the body during these kinds of
activities. The nervous system assists in
regulating the heart rate .

I need to remember..

• I need to remember . . .
• Systems do not stand alone they must work with
  other systems to enable the organism to function
  properly.
• Each system has specific functions that it must
  perform, but each system is closely connected to
  other systems in the body and works with them to
  perform its functions.
