Is the nutrients travel through the deoxygenated blood to reach the body cell?

Nutrients are transported to body cells through the bloodstream. Deoxygenated blood is pumped to the lungs to pick up oxygen, while nutrient-rich blood is circulated through the body to deliver nutrients to cells. Oxygen and nutrients are carried by separate systems within the blood to reach their respective destinations.


How do your bodies deliver nutrients into the blood?

Your body delivers nutrients into the blood through the food that you eat. As food is broken down the nutrients are absorbed into the blood stream and are then carried to tissues and organs throughout the body.


How do digested nutrients get in the blood stream?

After food get digested, there are enzymes that break down larger molecules such as proteins and carbohydrates into smaller molecules before it can pass into the blood stream. Mainly in the small intestine, nutrients pass into the blood stream. Depending on the type of "nutrient" that get passed through, some just diffuse through by difference in concentration gradient. Some require active pumps in the lining of the small intestine to pump the "nutrient" into the cell or blood stream. Hope I didn't confuse you too much. In short, some molecule just pass through. Some needs to be pumped across the cell membrane.


When does the exchange of nutrients and waste materials?

I'm assuming you mean 'where' in the body, as opposed to 'when'. In terms of when, it happens all the time! The exchange of nutrients from food mainly happens in the intestine, though other nutrients can be absorbed elsewhere in the body sometimes. These enter your blood stream here and travel to the relevant area of your body using the circulation. Waste will enter your blood stream as well but be filtered out of your blood by your kidneys and is passed out of the body as urine.


What organ system transports nutrients metabolic wastes gases and defense cells?

The circulatory system is responsible for transporting nutrients, metabolic wastes, gases, and defense cells throughout the body. This system uses blood as the main transport medium, which is pumped by the heart through blood vessels to reach different tissues and organs.
