Carbohydrates are present in food in the form of starch, sugar and fiber.
A carbohydrate is a molecule containing carbon, oxygen and hydrogen, and can be either simple or complex.
Monosaccharides are a single sugar molecule, while disaccharides are two simple sugar molecules linked together.
More complex carbohydrates are called polysaccharides and are multiple sugar molecules linked together.
Carbohydrates are primary energy producers.
The two main forms of carbohydrates are: sugars such as fructose, glucose, and lactose. Starches, which are found in foods such as starchy vegetables (like potatoes or corn), grains, rice, breads, and cereals.
What is the difference between the pulmonary circulation and the systemic circulation?
Pulmonary circulation only occurs between the heart and the lungs.
The pulmonary circulation is the portion of the circulatory system which carries deoxygenated blood away from the right ventricle of the heart, to the lungs, and returns oxygenated blood to the left atrium and ventricle of the heart.
Systemic circulation refers to the circulation of blood in which oxygenated blood is pumped from the heart to the body and deoxygenated blood is returned back to the heart.
Systemic circulation occurs between the heart and the entire body.
SYSTEMIC CIRCULATION carries oxygenated blood away from the heart to the body, and returns deoxygenated blood back to the heart.
