The Smooth Endoplasmic Reticulum has a wide range of functions in carbohydrates and lipid synthesis. Phospholipids and cholesterol are necessary for the construction of cell membranes. It serves as a transitional area for vesicles that transport ER products to various destinations. In liver cells, Smooth ER helps detoxify certain compounds. In muscle contraction, and in brain cells it synthesis male and female hormones.
Oxygen from the respiratory system is delivered by the circulatory system.
<h3>What is the relationship between respiratory and circulatory system?</h3>
The respiratory system is responsible for delivering oxygen to the circulatory system that is made up of blood vessels which carry blood to the heart and then all cells of our body. Arteries carry blood that is loaded with oxygen from the heart to all cells whereas veins carry deoxygenated blood back to the heart and then to the lungs for disposing carbondioxide. The circulatory system carries oxygen and nutrients to the cells, and removes waste products such as carbon dioxide.
So we can conclude that Oxygen from the respiratory system is delivered by the circulatory system.
