  1. Reporting Category 4 Biological Processes and Systems Station 13 Interaction Among Animal Systems

  2. 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.

  3. Pre-Preview Question • Which two body systems interact to send oxygen throughout the body?  • Digestive and circulatory • Circulatory and respiratory • Circulatory and Endocrine • Skeletal and Circulatory

  4. Pre-Review Question • Which of the following is a direct interaction of the skeletal, muscular and nervous systems? • Feeling tired after eating a meal. • Movement of a person’s arm. • Healing of a cut on the arm. • Increased production of hormones.

  5. Pre-Review Question • Which system of the body would be most directly affected if excess cholesterol led to plaque deposits in arteries? • Cardiovascular system • Immune system • Endocrine System • Integumentary System

  6. 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.

  7. 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.

  8. 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 body—the circulatory system transports the waste products internally and the integumentary system excretes them through the skin’s 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 .

  9. 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.

  10. Post Review Question • What two body systems are most useful in getting nutrients from the food you eat to your brain? • Muscular and endocrine • Nervous and digestive • Nervous and Circulatory • Circulatory and Digestive

  11. Post Review Question • The human reproductive system produces the eggs and sperm used in sexual reproduction. Which system is most responsible for controlling the development and function of the reproductive system? • Digestive • Circulatory • Respiratory • Endocrine
