food ingested is broken down into smaller pieces via mechanical and chemical digestion. this takes place in the mouth stomach and the intestine. it is then absorbed (taken in) by cells of the gut called enterocytes. these cells then transfer the nutrients into the capillaries supplying the gut. in this way nutrients from your diet enter the circulatory system to transfer them to other tissues
Nutrients from the digestive system enter the circulatory system. From there, they are transported to all body cells.
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.
Most nutrients enter the circulatory system through the small intestine. After digestion, nutrients are absorbed by the intestinal villi and then transported into the bloodstream. From there, they travel to the liver via the hepatic portal vein for processing and distribution to the rest of the body. This efficient system ensures that essential nutrients reach cells and tissues where they are needed.
The circulatory system is responsible for the distribution of food nutrients to different parts of the body. After nutrients are absorbed in the digestive system, they enter the bloodstream, where the circulatory system transports them to cells and tissues. This system includes the heart, blood vessels, and blood, ensuring that essential nutrients reach their destinations efficiently.
The nutrients of food are absorbed at the intestine from where they reach the organs and tissues through the circulatory system.
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.
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.
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.
The reproductive system and circulatory system are interconnected through the transport of hormones and nutrients essential for reproduction. Hormones such as estrogen and testosterone, produced by the reproductive organs, enter the bloodstream and regulate various functions, including the menstrual cycle and sperm production. Additionally, the circulatory system delivers oxygen and nutrients to reproductive tissues, supporting their health and function. This interplay is crucial for processes like fertilization, pregnancy, and overall reproductive health.
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 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.
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.
