Functional Relationship of the different Organ
Systems in ensuring Animal Survival

There are various systems in the animal’s
body:
• Muscular System
• Respiratory System
• Digestive System
• Skeletal System
• Circulatory(Cardiovascular) System
• Excretory(Urinary) System
• Reproductive System
• Nervous System
• Immune System
• Endocrine System
Digestive System
Major organs: Esophagus, stomach, small

intestine, large intestine, rectum.
The digestive system breaks down food into nutrients
such as carbohydrates, fats and proteins. They can
then be absorbed into the bloodstream so the body
can use them for energy, growth and repair. Unused
materials are discarded as faeces (poo).
Respiratory System
Major organs: Nose, Trachea, Bronchi, Lungs.

The respiratory system is the network of organs and tissues
that help you breathe. It includes your airways, lungs and
blood vessels. The muscles that power your lungs are also
part of the respiratory system. These parts work together to
move oxygen throughout the body and clean out waste
gases like carbon dioxide.
• Allows you to talk and to smell.
• Warms air to match your body temperature and
moisturizes it to the humidity level your body needs.
• Delivers oxygen to the cells in your body.
• Removes waste gases, including carbon dioxide, from
the body when you exhale.
• Protects your airways from harmful substances and
irritants.ste gases like carbon dioxide.
Circulatory System
Major Organs: Heart and Blood vessles.
• Also known as Cardiovascular system.

• transport oxyge, nutrients,and other substances to the cell
and transport wastes, carbon dioxide and other
substances away from the cell;helps to stabize body
temperature and pH.
Excretory System
Major Organs:Kidneys, Urinary bladder, Ureter.
• Also known as Urinary System.

• Removes excess water,salts, and waste products from
the blood and body and controls pH.
Immune System
Major organs:Bone marrow and Thymus.
• The immune system defends the body from infection. It is

made up of a complex network of cells, chemicals, tissues
and organs. An underactive or overactive immune system
can cause health issues. The immune system’s job is to
protect the body from infection.
Nervous System
Major organs:Brain and Spinal cord.

• Collects, transfers and process information and direct
short term change in other organ systems.
• it controls your movements, thoughts and automatic
responses to the world around you. It also controls other
body systems and processes, such as digestion,
breathing and sexual development (puberty).
Endocrine System
Major organs:Glands produce hormones.

• Provides communication within the body via hormone and
directs long term change in other organ systems to
maintain homeostasis.
Muscular System
Major organs: Muscles and Tendons.

• Provides movement support and heat production.
• It permits movement of the body, maintains posture, and
circulates blood throughout the body. The muscular
systems in vertebrates are controlled through the nervous
system although some muscles (such as the cardiac
muscle) can be completely autonomous.
Skeletal system
Main organs:Bones, Cartilages, Ligaments.

• skeletal system The framework of the body, consisting of
bones and other connective tissues, which protects and
supports the body tissues and internal organs. The
human skeleton contains 206 bones, six of which are the
tiny bones of the middle ear (three in each ear) that
function in hearing.
• Supports and protects soft tissues of the bodyl; provide
movement at joints;produce blood cells.
Each individual body system works in conjunction with other
body systems. The circulatory system is a good example of
how body systems interact with each other. Your heart
pumps blood through a complex network of blood vessels.
When your blood circulates through your digestive system,
for example, it picks up nutrients your body absorbed from
your last meal.
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. Meanwhile, the circulatory system carries
hormones from the endocrine system, and the immune
system’s white blood cells that fight off infection.
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.
Even seemingly unrelated body systems are connected.
Your skeletal system relies on your urinary system to
remove waste produced by bone cells; in return, the bones
of your skeleton create structure that protects your bladder
and other urinary system organs. Your circulatory system
delivers oxygen-rich blood to your bones. Meanwhile, your
bones are busy making new blood cells.
Working together, these systems maintain internal stability

and balance, otherwise known as homeostasis.
