The Circulatory System In The Human Body
The body is made up of a number of systems that all interlink and produce everything we need in order to survive. Within the body there is the digestive system; the circulatory system, the nervous system, the muscular system, the skeletal system and the reproductive system. These systems are all part of one another and they share organs, tissues and cells and that is how they interlink.
The diagram above shows each system and where they are located in the body. Each system is shown in a different image but clearly the systems that are in the same area of the body interlink and work together to do two different jobs.
Firstly, the skeletal system is the basic frame of our body and it consists of 206 bones which are all connected by a number …show more content…
Mentioned above, nutrients from food travels throughout the body through the blood and these nutrients are sourced from the digestive system as the nutrients are produced by the breakdown of food. The absorption of food occurs in the small intestines and inside the small intestines there are thin finger like tubes called villi. Digested food enters the small intestines and each villus allows absorption of the nutrients into the blood stream. There are three main ways the nutrients are absorbed into the blood stream and these are; passive diffusion, active transport and phagocytosis. Passive diffusion is diffusion of substances across a membrane and the nutrients pass through capillaries and capillary walls meaning they pass through the membrane within the capillary wall. Active transport is when molecules use energy to move from a low concentrated area to a high concentrated area. Inside the small intestines, there is a low concentration of blood therefore the nutrients moves from the low concentration area through the cell membrane to the high concentration of blood in the capillaries and into the blood stream. Phagocytosis is when living cells called phagocytes engulf harmful or infectious cells and get rid of them. The phagocytes engulf the bad chemicals from digested food and get rid of them through waste products. The link between the circulatory and digestive system is through the transfer of nutrients through different types of
