The function (job) of the intestine is to digest and absorb food. Digestion means breaking down food into soluble substances which can be absorbed. For example, starch is broken down into sugar (glucose) and protein is broken down into amino acids. So, the substances which are taken in by the blood from the intestine are digested foods, for example sugar (glucose) and amino acids. Most food is absorbed by the small intestine. Undigested food and water pass into the large intestine which takes some of the water back into the blood.

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.
Density information for a substance is useful because it is always the same regardless of the amount of substance there is. Take water for example. The density of water is same regardless if you have ten gallons of it or tablespoon of it. (1 gram/milliliter at STP). Since the density of a substance is always the same this property can exploited to determine the identity of unknown substances.

No, haemoglobin is only found in red blood cells. It is a substance that is required to take up oxygen for transport from the lungs to the rest of our body.
Your small intestines absorb the food and nutrients as well as the water you take in. You can not survive without most of it.

Arteries take blood from the heart to the body. Capillaries are tiny blood vessels that enable substance exchange between the blood and the body tissues. Veins carry blood back to the heart.
