Question

question 4
where are peripheral chemoreceptors found?
red blood cells
kidneys
aorta and carotid arteries
lungs

Explanation:

Peripheral chemoreceptors are sensory cells that detect changes in blood oxygen, carbon dioxide, and pH levels. They are located in the aortic bodies (associated with the aorta) and carotid bodies (associated with the carotid arteries). Red blood cells carry oxygen, kidneys are involved in filtering blood and regulating fluid balance, and lungs are for gas exchange. None of these are the location of peripheral chemoreceptors.

Answer:

Aorta and carotid arteries.
