HUMAN SYSTEMS Digestive, Respiratory, Circulatory, and Excretory Systems

DIGESTIVE SYSTEM 1) Delivers nutrients (glucose) to the circulatory system

RESPIRATORY SYSTEM 2) Oxygen molecules move from the air to the alveoli of the lungs and then to the circulatory system O₂ O₂

CIRCULATORY SYSTEM 3) From the circulatory system, glucose and oxygen molecules move from the capillaries into the cells of the body where cellular respiration occurs

CELLULAR RESPIRATION oxidized 4) O₂ + C 6 H 12 O 6 (glucose) CO₂ + H₂O + ATP (energy)

REMOVAL OF CO₂ 5) The gas exchange process is reversed for the removal of CO₂ CO₂

HOMEOSTASIS - BLOOD SUGAR 6) The concentration of sugar in the blood is monitored Sugar can be stored or pulled from reserves (glycogen) in the liver and muscles to maintain a constant blood sugar level

AMINO ACIDS Amino Acids contained in proteins can also serve as an energy source, but first they must be deaminated, or chemically converted in the liver This produces a toxic ammonia product, which is converted to watersoluble urea and excreted by the kidneys 7)

1) 2) 3) 4) What is the main purpose of the Respiratory System? What is the main purpose of the Digestion System? Write the formula for Cellular respiration? What is a main purpose of the Circulatory system?
