Answer:
The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
Your circulatory system delivers oxygen-rich blood to your bones. Meanwhile, your bones are busy making new blood cells. Working together, these systems maintain internal stability and balance, otherwise known as homeostasis

The sympathetic nervous system controls the response to a threat. We perspire, breathe more quickly and get goosebumps and feel nauseated. The correct answer is c. sympathetic nervous system.
The autonomic nervous system responds to information about the body and the environment by either stimulating or inhibiting bodily functions, typically through the sympathetic or parasympathetic nervous systems.There are two primary divisions of the autonomic nerve system-
- Sympathetic
- Parasympathetic
The sympathetic nervous system controls the "fight-or-flight" reaction, which is activated by danger or stress and can lead to a number of physiological changes. Most blood vessels, including many in the epidermis, digestive tract, and kidneys, constrict when the sympathetic nervous system is stimulated. This happens due to norepinephrine, released by post-ganglionic sympathetic neurons, activating alpha-1 adrenergic receptors. Sympathetic nervous system may impact these organs while under threat or stress:eyes, heart, lungs, digestive tract, liver, and genitalia.
