In the small intestine
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.
digestive system throw the waste and dirt from the body and nutrients enters the circulatory system through capillaries.
Ingestion, digestion, absorption, and elimination.
The digestive system is responsible for themechanical and chemical digestion of food products, for the absorption of nutrients, and the excretion of waste products. The proper functioning of the digestive system is necessary for proper nutrient absorption. Nutrients are critical to ensure overall good general health.BASICALLY I JUST USED MY COMMON SCENSE hope i helped sorry if i didnt im not good in science
absorption
The digestive system absorbs nutrients from the food and these nutrients are carried to their eventual targets (liver, muscle and fat tissue) within the circulatory system. Digestion requires that the body redirect blood flow towards the digestive system in order to adequately handle the metabolic needs of digestion as well.
Digestion
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 circulatory and digestive systems work together to ensure that mammals survive by facilitating nutrient absorption and distribution. The digestive system breaks down food into essential nutrients, which are then absorbed into the bloodstream via the intestinal walls. The circulatory system transports these nutrients to cells throughout the body, providing the energy and building blocks necessary for growth, repair, and overall functioning. Additionally, the circulatory system helps remove waste products produced during digestion, maintaining internal balance and health.
The immune system evolved by piggybacking on the circulatory system, as immune cells circulate throughout the body via the blood. The lymphatic system also utilizes the circulatory system to transport lymph fluid and immune cells. Additionally, the endocrine system often influences digestive system functions by releasing hormones that regulate digestion and nutrient absorption.
The process of food entering the bloodstream is called absorption. Enzymes that are released by various organs of the digestive system assist in the chemical breakdown of food into smaller molecules so that it can be absorbed by the body.
This is an example of absorption, which is the process by which nutrients and other molecules pass through the walls of the digestive system and into the bloodstream or lymphatic system to be used by cells in the body.
