Nutrients from the digestive system enter the circulatory system. From there, they are transported to all body cells.
The nutrients of food are absorbed at the intestine from where they reach the organs and tissues through the circulatory system.
The capillaries are the site in the circulatory system where nutrients enter and wastes leave the tissues. The thin walls of the capillaries facilitate this diffusion.
Absorption is the process that takes nutrients through the small intestine wall. These nutrients then enter the circulatory system, which carries the nutrients to all body cells.
Most nutrients are just dissolved in the plasma of the blood. They are transported to the cells when the heart pumps the blood through arteries, arterioles and capillaries. Nutrients diffuse through the walls of capillaries and enter cells.
The lung or pulmonary system is the essential respiration organ that makes it possible for oxygen to enter the circulatory system.The alveoli struture makes it possible for oxygen to enter the circulatory system.
blood septicemia.a grave condition .
Products of carbohydrate digestion and protien digestion move through brush border cells, diffuse through the interstitial fluid inside the villus, then enter a capillary. Products of fat digestion also cross the brush border cell and interstitial fluid, but they enter lymph vessels which eventually carry them to the blood.
The small intestine is the site of most chemical digestion and absorption in the digestive tract. During absorption, nutrients enter the bloodstream, and the circulatory system can then transport these nutrients to all body cells.
Nutrients from food and beverage is absorbed inside the walls of the small intestine. As we digest our food, all nutrients are taken in the small intestine and would most probably then enter our bloodstream from there on.
First, with the help of digestive system the food is broken down into smaller pieces which we eat and nutrients are separated which are further transported with the help of blood circulatory system.
Three examples would be: -digestive system, where nutrients enter the bloodstream -endocrine system, where hormones enter the bloodstream -immune system, where blood, organs, tissues, cells, and cell products work together to respond to dangerous organisms that enter the body.
