Which of the following systems is mismatched?
Urinary -- Includes kidney & bladder; removes wastes
Endocrine -- Includes the hormone producing glands, involved in metabolism and growth, puberty, sexual reproduction, etc.
Respiratory -- Includes lungs, involved in gas exchange & pH balance
Digestive -- Includes blood vessels, transports nutrients and gases to organs and wastes (CO2) from organs
The Correct Answer is D
A. Urinary – Includes kidney & bladder; removes wastes: The urinary system includes the kidneys and bladder, which remove nitrogenous waste and regulate water and electrolyte balance.
B. Endocrine – Includes the hormone-producing glands: The endocrine system includes pituitary, thyroid, adrenal glands, etc., involved in metabolism, growth, and reproduction.
C. Respiratory – Includes lungs, involved in gas exchange & pH balance: The lungs are central to the exchange of O₂ and CO₂, which also helps regulate blood pH.
D. Digestive – Includes blood vessels, transports nutrients and gases to organs and wastes (CO2) from organs: Blood vessels are primarily part of the circulatory system, not the digestive system. The digestive system includes the mouth, esophagus, stomach, intestines, liver, pancreas, etc., which process food and absorb nutrients-not gas transport.

Tissue comes before cell, which is anatomically incorrect.
