What system carries nutrients throughout the body?
The circulatory system is responsible for transporting essential nutrients throughout the body. It picks up the nutrients from the small intestine and large intestine, and brings the nutrients to cells in the body.
What system carries oxygen and nutrients to the cells in the body?
There are many Organ System for Food and Oxygen. The Food Organs are the Mouth, Pharynx, Esophagus, Stomach, Liver, Pancreas, Small Intestine, Large Intestine. The Air Passage Organs is in the Nose, Trachea, Lungs, Heart. This Topic is all about the Circulatory system, and the Digestive System
What is the difference between macroorganism and microorganism?
Micro-organisms- needed in small quality Macro-organisms - needed in big quality
How do needed substances travel through the body?
Your circulatory system transports materials throughout your body. This is not the sole transport system, but the primary one. The lymph system is used to carry fat molecules that have been absorbed from the small intestine, but the lymph system will ultimately end up emptying back into the circulatory system.
What type of organisms first move into an area after a primary disturbance A Organisms that reproduce slowly B Large predators C Small organisms D Animals with long lives?
Small animals that can live in severe conditions -Apex
How do organisms live without a circulatory or respiratory system?
You don't need a "system" if you're small enough so that the function can be distributed throughout your entire body - as are all single celled organisms. But it works all the way up through jelly fish.
What comes after the small intestine the villi or the circulatory system?
The large
What do platlets do?

Circulatory system
How is your small intestine related to the circulatory system?
no it is a part of the digestive sistem
Where does food leave the digestive system and into the circulatory system?
digestive system throw the waste and dirt from the body and nutrients enters the circulatory system through capillaries.

What organ carries nutrients and passes it to the bloodstream?
The small intestines to be exact. :)
Where does most absorption of the end products of digestion into the circulatory system?
In the small intestine
What does the digestive system do for the circulatory system?
When your food is being digested and it is in your small intestines and the villi sucks up the nutrients it gives the nutrients to blood vessels which take it to your cells. Small intestines and villi are parts of digestive system. Blood vessels and cells are part of circulatory system.
Why is it important your body has a circulatory system?
If we were small enough we could absorb all our oxygen and nutrients by diffusion. But because we're as big as we are it would take too long for substances to diffuse to everywhere they need to go. So we have to have a more efficient means of getting oxygen and nutrients to where they're needed and that is the circulatory system.
