Question

human reproductive system test unit test
it is important that you maintain a healthy weight both for your overall health and so that your respiratory system can
(1 point)
○ deliver oxygen more adequately
○ pump blood more forcefully from the heart
○ allow for smaller amounts of air to enter your lungs
○ keep capillaries constricted

Explanation:

To solve this, we analyze each option:

• The respiratory system's main role is gas exchange (delivering oxygen and removing carbon dioxide). A healthy weight supports the respiratory system's function. "Deliver oxygen more adequately" matches the respiratory system's purpose.
• "Pump blood more forcefully from the heart" is a circulatory (heart) function, not respiratory.
• "Allow for smaller amounts of air to enter your lungs" is incorrect; a healthy weight should allow more, not less, air.
• "Keep capillaries constricted" is not a respiratory system goal; capillaries constricting would hinder oxygen delivery.

Answer:

A. deliver oxygen more adequately
