Question

students were engaged in an argument about body systems working together to supply cells with necessary nutrients and oxygen so that the body gets the energy it needs to perform life - based work. which argument best supports how nutrients and oxygen get to cells to provide energy?
a the nervous system regulates all the other body systems, the digestive system breaks down food into usable nutrients, and the cardiovascular system takes in oxygen for the cells.
b the digestive system breaks down food into usable nutrients, the cardiovascular system delivers oxygen to the cells, and the excretory system removes waste from the body.
c the cardiovascular system delivers oxygen to the cells, the immune system fights off infections, and the respiratory system takes in food needed for nutrients in the body.
d the digestive system breaks down food into nutrients, the respiratory system takes in oxygen, and the cardiovascular system delivers the oxygen and nutrients to the cells.

Explanation:

The digestive system breaks down food into usable nutrients, the cardiovascular system delivers oxygen to the cells, and the excretory system removes waste from the body. This option comprehensively describes how different body systems (digestive, cardiovascular, excretory) work together to supply cells with necessary nutrients (from digestion), oxygen (delivered by cardiovascular), and remove waste (excretory), which is essential for energy production as cells need these to function and produce energy.

Answer:

B. The digestive system breaks down food into usable nutrients, the cardiovascular system delivers oxygen to the cells, and the excretory system removes waste from the body.
