Lewis is exercising and his muscles need oxygen. which best describes how systems interact to bring his body into homeostasis? a) the circulatory system brings oxygen to the respiratory system, which delivers oxygen to the muscular system. b)the respiratory system brings oxygen to the circulatory system, which delivers oxygen to the muscular system. c) the respiratory system brings oxygen to the circulatory system, which delivers oxygen to the skeletal system. d) the circulatory system brings oxygen to the respiratory system, which delivers oxygen to the skeletal system.

The correct answer is option B, that is, the respiratory system brings oxygen to the circulatory system, which delivers oxygen to the muscular system.

The respiratory system works in close harmony with the circulatory system for the conduction and transfer of carbon dioxide and oxygen gases. Each and every cell in the body requires oxygen to work accurately.  

The respiratory system permits one to exhale carbon dioxide and inhale oxygen, and this system comprises nose, mouth, lungs, and trachea.  

After the air is mediated inside the body with the help of the respiratory system, the circulatory system plays its role, and transport the desired oxygen via the bloodstream to the various parts of the body. The circulatory system comprises blood vessels and the heart.  

B)The respiratory system brings oxygen to the circulatory system, which delivers oxygen to the muscular system.

Explanation:

Multi cellular organisms like humans have complex body structure. Various grade of organisation exist within our body. For each type of work there is a specialized organ system which performs the task with great efficiency. Two such organ systems in our body are respiratory system and circulatory system. Our respiratory system is responsible for exchange of gases while circulatory system is responsible for transport of minerals, food materials, gases etc. to the various tissues of the body. With the help of our respiratory system we are able to inhale oxygen and exhale carbon dioxide out of our body. Oxygen enters our respiratory tract through nostrils and finally it is absorbed by alveoli which are located inside the lungs. This oxygen is then transported to the left atrium of our heart with help of pulmonary veins. Once the oxygen rich blood reaches the heart, the heart pumps oxygen rich blood to the rest of the body with the help of various arteries.
