the only thing listed that is related is the hand.
To determine which organ is to the integumentary system what the lung is to the respiratory system, we need to understand the function of the integumentary system.
The integumentary system is responsible for protecting the body from the external environment. It includes the skin, hair, nails, sweat glands, and oil glands.
Now, let's consider the options:
A) Heart: The heart is part of the cardiovascular system, which is responsible for pumping blood throughout the body. It is not directly related to the integumentary system.
B) Kidney: The kidneys are part of the urinary system, responsible for filtering waste products from the blood. They are not directly related to the integumentary system.
C) Hand: The hand, along with other body parts, is covered by the skin which is part of the integumentary system. However, the hand itself does not play a fundamental role in protecting the body from external environment.
D) Brain: The brain is part of the nervous system, responsible for controlling bodily functions. It is not directly related to the integumentary system.
Therefore, out of the given options, the best answer is C) Hand. Though the skin covers the entire body, the hand is an appendage that comes in contact with the external environment and performs various functions, like touching, feeling, and interacting with objects.
