How do the lymph and immune systems depend on the cardiovascular system?

a. the cardiovascular system pumps lymph fluid through blood vessels.
b. nerve impulses from the brain are carried to the lymph nodes by blood.
c. white blood cells from the lymph and immune systems travel through blood vessels.
d. the lymph and immune systems do not interact with the cardiovascular system.

The correct answer is option C. "White blood cells from the lymph and immune systems travel through blood vessels".

Explanation:

The functions of the body are divided into different systems, which most of the time interact with each other to perform complicated processes. For instance, the immune system interact with the cardiovascular system upon an infection when white blood cells from the lymph and immune systems travel through blood vessels. Once the pathogens reach the lymph nodes they are filtered, acting as a barrier to isolate the infection where the white blood cells can attack.

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.
