How are carbohydrate polymers formed.

Explanation:

Carbohydrates are made of sugar molecules, including glucose, fructose, and arabinose. These sugar molecules, or monomers, can be combined to form dimers such as sucrose or lactose, polymers such as starch or cellulose, or be added to other molecules to form glycosides. This occurs through a dehydration synthesis reaction.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
