The diagram below shows a comparison between a healthy artery and one with arteriosclerosis. Which body function is, most affected by arteriosclerosis? A. circulating blood to tissues B. assembling amino acids into proteins C. replacing damaged cells with new cells D. breaking down food particles into molecules

D

Use the information below to answer the following question(s). Most organisms need oxygen for their cells to function normally. In mammals, two organ systems work together to move oxygen throughout the body. The respiratory system brings oxygen into the body from the environment. Which of these body systems is directly involved in the delivery of oxygen to the major organs of the human body? A. the nervous system B. the digestive system C. the endocrine system D. the circulatory system
