A) urinary
B) digestive
C) cardiovascular
D) respiratory
E) lymphatic

Answer 1

The cardiovascular system is responsible for the internal transport of cells and dissolved materials, including nutrients, wastes, and gases.

Step-by-step explanation:

The cardiovascular system is responsible for the internal transport of cells and dissolved materials, including nutrients, wastes, and gases. It works closely with the respiratory system to facilitate gas exchange. Oxygen is absorbed by the blood in the lungs and then transported through a vast network of blood vessels to cells throughout the body where it is needed for aerobic cellular respiration. The same system absorbs carbon dioxide from cells and carries it to the respiratory system for removal from the body.
