Which body system is directly responsible for delivering nutrients to cells in the body?

I'd say circulatory system, because nutrients that are decomposed in the small intestine go into the blood stream to be transported to wherever part of the body the nutrients are required.

When you eat, your stomach produces glucose that acts like an acid to break down the food, pass it into your blood and absorb it into the body tissues. Insulin packs the food into your body tissues and, at the same time, flushes the excess glucose out of your body. Insulin is made by the pancreas and diabetes occurs when the pancreas fails to produce enough insulin to do these two jobs. Therefore an excess of glucose also builds up in the blood and bercause it is acidic, it eats away at your body's blood vessels. It attacks the liver, kidneys, eye retinas and the toes causing kidney disease, blindness and sometimes requiring amputation of the feet. So, the second part of your question is correct: the cells cannot deliver energy without insulin but there is also a build up of glucose in the blood which attacks the blood vessels.

im studying the digestive system right now, so i'll have a go at this question (u may want to chec accuracy).\nthe cell gets the carbon it needs via the blood supply. when we eat, all the nutrients are broken down and molecules such as hydrogen, oxygen and carbon are filtered into the blood stream so that they can be passed on to all the cells in th body.\n\ndoes that help?

You are probably referring to metabolism.  Metabolism is a collection of chemical reactions that takes place in the body's cells to convert the fuel in the food we eat into the energy needed to power everything we do, from moving to thinking to growing. Specific proteins in the body control the chemical reactions of metabolism, and each chemical reaction is coordinated with other body functions. In fact, thousands of metabolic reactions happen at the same time - all regulated by the body - to keep our cells healthy and working.

The circulatory system absorbs the stuff you eat once it's broken down.  The lymphatic system helps protect you from bad stuff you've eaten.

The excretory system is responsible for removing waste materials from the body. The primary organ for excretion is the kidney which releases waste in the form of urine. Another organ of excretion is the skin which removes waste from the body in the form of sweat. Another organ of excretion is the lung. The lung is responsible for removing Carbon dioxide and water vapor. And the last member of the said system is the large intestine. The large intestine is responsible for removing undigested food from the body. The process of doing so is called elimination rather than excretion.

The endocrine system is based upon the notion that a set of chemical signals, hormones, can travel through the body to regulate critical homeostatic mechanisms. These include things like sugar utilization (insulin and glucagon), reproduction (gonadotrophic hormones), heart rate (many hormones including adrenaline or epinephrine), temperature control (many hormones), feeding behaviors (hormones such as leptin and ghrelin), etc. By assessing the metabolic needs and survival requirements of various body tissues and cells, the endocrine system maintains the appropriate balance between differing control systems.

When you eat, the digestive system breaks down food & its nutrients into forms that can be absorbed by the bloodstream; blood flows to skeletal muscles as you move them (skeletal muscles are attached to bones - these are the muscles that are controlled by the voluntary movements you make - like walking, running, clicking the mouse button, etc.). The bloodstream takes oxygen & nutrients to the muscles. \nSo, the nutrients that end up going to your muscles are dependent on what foods your eating.

Mouth, esophagus, stomach, small intestine, large intestine, colon, rectum, anus are the parts the food or the waste from food travel through.  Side line contributors are glands such as\nsaliva glands, liver, gall bladder, pancreas.

Hi there !\nWhat do you mean by the question ? \nYou expect somebody to describe the "entire digestion" and the "metabolism mechanism" of the Human body in this column ?\nBetter verify the "Book of Physiology by Guyton" or "Chatterjee"..they have given beautiful descriptions ! \nbest wishes !

The circulatory system comprises all structures that relate to the circulation of blood throughout the body.  This includes the heart, the aorta (main artery coming out of the heart), the major organ arteries, the smaller branch arteries going into the organs, arterioles (even smaller branch arteries), capillaries (fine, almost microscopic vessels where oxygen and nutrients are delivered to the organ), venules (small veins that start the return of blood away from the organ), small veins, larger veins, inferior vean cava (main vein from the lower 2/3 of the body), superior vena cava (main vein from the upper 1/3 of the body), and finally the heart again.  The circulatory system is essentially a closed plumbing system, driven by the beating of the heart.

Respiratory and circulatory.\n\nRespiratory brings oxygen into your body.  Circulatory pumps blood, which carries the oxygen, to the cells in the rest of your body.

In mulitcellular organisms, it is more difficult for cells to take in nutrients and excrete waste.  Single celled organisms can easily do this in their environment.  But in multi-celled organisms, cells are found layer upon layer.  They can't easily get nutrients, and any waste that they excreted would just stay there, building up in toxic quantities that would kill the entire organism.  Thus, we have circulation, a network of vessels that reaches out throughout the organism, easily reaching all the cells and allowing them to do their thing.

Blood vessels nourish all parts of the digestive system from mouth to anus, but the circulation to the small intestines is probably one of the most importantfor distribution of nutrients. The small intestine is the site of both digestion and absorption of PFC nutirents from the food taken in at our mouth; protein is broken down into smaller subunits called amino acids, complex carbs are broken down into smaller monosaccharides, lipids are broken down into glycerol and fatty acids, and nucleic acids are broken down into nucleotides.  These smaller molecules are more easily absorbed from the lumen in the intestine to the villi. Thus the nutirents are more readily available for the many chemical reactions for misc cells metabolism.  The intestines are lined with epithelial tissues that have a unique arrangement of intestinal projections called "villi".  These villi increase the surface area for absortion of these molecules digested for us.  The villi have blood vessels (capillary) and lacteals in them so that the nutrients we ate, digested and absorbed can be transported to the blood or lymph vessel in the villi and then eventually go to to-thru blood stream so that any cells throughout the body that need nutrients can be "fed," esp so that cell respiration can take place. The blood vessels in the stmach make it easy for some molecules to even be absorbed in the stomach.  Same is true in the  mouth. Water, misc drugs, sugar and ions can be absorbed into the blood vessels located under the tongue.\n\nOne of the most COMPLEX sites connecting the circulatory system and the digestive system is the hepatic portal system (and all associated vessels) that help to transport and process MANY molecules-nutrients as they go thru the sinuses in the liver. The liver has hundreds of functions related to the complex metabolism and processing of proteins, fats and carbs.

The endocrine system  regulates mood, growth and development, tissue function, metabolism, and sexual function and reproductive processes.It is in charge of body processes that occur slowly. The most imporant parts of the endocrine system are hormones and glands. Hormones transfer information and instructions from one set of cells to another and only affect certain cells. Glands produce and secrete chemicals. A gland selects and removes materials from the blood, processes them, and secretes the finished chemical product for use somewhere in the body.

In general, the endocrine system is in charge of body processes that happen slowly, such as cell growth. Faster processes like breathing and body movement are monitored by the nervous system. But even though the nervous system and endocrine system are separate systems, they often work together to help the body function properly
