How All Aspects of the Circulatory System Work Together
The circulatory system includes multiple organ systems, the cardiovascular (heart and blood) system, the respiratory (breathing) system, a part of (kidneys) the urinary (pee) system, the immune or lymphatic (germ defence) system, and a part (liver) from the digestive system. Since no systems are able to work without the brain, the brain and its nervous system are part of every system. To stay alive, all body cells need a constant, continuous delivery of oxygen, food, other substances, and waste removal, and that is what the circulatory system is for.
It starts in the heart where blood is pumped through the pulmonary artery to the lungs where a gas exchange takes place in the alveoli, and now the new, oxygen-rich blood is carried back to the heart through the pulmonary veins. Afterwards, blood is pumped throughout the body, and into the coronary arteries. Blood travels through arteries, then through smalller arteries called arterioles, then into capillaries where a gas exchange takes place with the body cells. The blood then travles into small veins called venules, and then through veins and back to the heart for the process to be repeated.
The cardiovascular system is the transport system for oxygen, wastes, and nutrients where as the respiratory system is the oxygen supply system, which is essential for cells. The digestive system is the nutrients supply system, the kidneys and liver are the filtration system that remove some of the wastes.

Below are some helpful jot notes on the contributing systems.
CARDIOVASCULAR SYSTEM
= heart, blood, blood vessels
= tissues
= epithelial, muscle, nerve, connective
= pump blood around body to supply cells with oxygen , food, other essential nutrients, and remove wastes
= oxygen diffuses out of the red blood cells into the tissues and at the same time carbon dioxide diffuses into the red blood cells out of the tissues as it travels through the blood stream
= transports nutrients, dissolved gases (oxygen, carbon dioxide), and wastes to and from individual cells
= oxygen rich blood - red - arteries - supplies body with oxygen (carotid, femoral, etc.)
= oxygen poor blood - blue - veins - drains blood back to heart (jugular, tibial, etc.)
DIGESTIVE SYSTEM
= mouth, esophagus (pharynx and epiglottis), stomach, liver, pancreas, small and large intestines, anus
= tissues
= epithelial, muscle, nerve, connective
= breaks down food, releases essential nutrients that are absorbed by the bloodstream, removes wastes
= breaks down food into small particles, called nutrients, that can be transported by the circulatory system to all the cells of the body
MUSCULAR SYSTEM
= muscles
= play a role in movement and locomotion
= cardiac - heart only, automatic
= smooth - usually is the inner lining of hollow organs (eg. stomach)
internal
= digestive - push food along ______,
= cardiovascular - makes the heart beat
IMMUNE SYSTEM
= lymphocytes, etc./white blood cells
= destroys harmful bacteria and viruses
= found in circulatory and lymphatic systems, and
other tissues
NERVOUS SYSTEM
= core
= brain, spinal cord (both receive, process, and send info along nerves), sensory organs (eyes, ears, nose, taste buds)
= tissues
= epithelial, nerve, connective
= body's primary control system, uses electrical signal messaging, responds to changes in the internal and external environments of the body, coordinates the functions of all other organ systems
RESPIRATORY SYSTEM
= lungs, trachea (windpipe), blood vessels, esophagus (larynx and epiglottis)
= located in head, neck, chest
= tissues
= epithelial, muscle, nerve, connective
= oxygen is used for "burning" energy rich foods from eating to release energy (energy is essential for body and cells to stay alive)
= exchanges oxygen and carbon dioxide between blood and the external environment (releases the carbon dioxide before it poisons us)
= the harder work, the faster we breathe so we can supply our "hard-working" muscles with enough oxygen
URINARY SYSTEM
= kidneys, ureters, bladder
= removes excess water and wastes from blood by filtering blood and mixing it with the 2 liquids
