The document discusses the interactions between the digestive, circulatory, respiratory, and excretory systems. The digestive system breaks down food and absorbs nutrients into the bloodstream. The circulatory system then transports these nutrients and oxygen from the respiratory system to all the body's cells. The excretory and respiratory systems both work to remove waste from the body. These systems are all interdependent, with each relying on the others to function properly and sustain life.

9. After going through this module, you are expected to:
1. Illustrate how ingestion, absorption, assimilation, and
excretion take in the interaction of digestive system with
the circulatory, respiratory and excretory systems.
2. practice moderation and healthy lifestyles
13. A.Compare the rate of your breathing before
and after exercise.
B.What have you noticed with your body
after the exercise?
C.Did you sweat out or perspire?
D.Do you need to drink water after the
exercise?
E.What do you think are the organ systems
involved as you performed this activity?
14. The human body contains trillions of cells, 78 different organs and more
than 60,000 miles of blood vessels if you stretched them end-to-end.
Incredibly, all of these cells, vessels and organs work together to keep you
alive.
15. Every cell in the body needs energy to perform its duties and
stay alive. Cells use energy when they have the nutrients they
need to perform. The digestive system converts bulk foods
like bread and meat into their simple components, and absorbs
them into the bloodstream through the intestines. The
circulatory system moves the nutrients from the intestines to
the cells that need them.
16. The respiratory
system provides the
oxygen necessary for
cells to metabolize,
and the circulatory
system moves the
oxygen around the
body and to the cells.
17. The excretory system and
respiratory system both get
rid of waste products. The
excretory system disposes of
all food not absorbed by the
body, and any foods that the
digestive system couldn't
break down.
19. When the stomach is
empty and blood glucose
levels are low, the
digestive system
receptors and the brain
respond by making you
feel hungry—your
stomach may “growl,”
and you may feel pain or
discomfort in your
midsection.
20. Your blood also carries oxygen inhaled by
the lungs. Your circulatory system delivers
oxygen and nutrients to the other cells of
your body then picks up any waste products
created by these cells, including carbon
dioxide, and delivers these waste products to
the kidneys and lungs for disposal.
21. The circulatory system carries
hormones from the endocrine
system, and the immune system’s
white blood cells that fight off
infection.
22. Each of your body systems relies on the others to
work well.
• Your respiratory system relies on your
circulatory system to deliver the oxygen it
gathers, while the muscles of your heart cannot
function without the oxygen they receive from
your lungs.
• The bones of your skull and spine protect your
brain and spinal cord, but your brain regulates
the position of your bones by controlling your
muscles.
• The circulatory system provides your brain with
a constant supply of oxygen-rich blood while
your brain regulates your heart rate and blood
pressure.
23. Another example, the cardiovascular, urinary, and
lymphatic systems all help the body control water
balance. The cardiovascular and lymphatic systems
transport fluids throughout the body and help
sense both solute and water levels and regulate
pressure.
24. Which system in your
body is the most
important for you?
Why?
