How complimentary activity of major body systems provide cells with oxygen and nutrients and removes CO2?

There are two organ systems that work in conjunction with each other to provide tissues with oxygen and remove carbon dioxide.  Those are the respiratory and the circulatory system (the major organs of these systems being the lungs and the heart respectively).\n\nNutrients are provided by the combined actions of the digestive and circulatory system, and wastes are removed through the combined actions of the circulatory and excretory systems.

Each cell must have the ability to get oxygen, nutrients, get rid of waste products like CO2. This is accomplished by the fluid in the tissues and the fluid around each cell. When blood goes through a capillary fluid can leak to the tissues, this is where it comes from. Now through the process of osmosis some of this fluid must go back into the circulatory system, but not all of it does. The fluids left over makes up the lymphatic fluid and is carried in lymphatic vessels.

muscles provide both support and functionality. Muscles pull ang push on bones so that they may work. Digestive system digests food and provides energy supply and calcium deposits. Circulatory system transports essential nutrients into bones. Nervous system regulates the action of the bones whether to move or not. Endocrine system parathyroid gland regulates bone formation and bone breakdown. Integumentary system protects bone and muscle from outside environment. Respiratory system brings oxygen

After eating, astronauts settle down to the assigned tasks of the day, either supervising experiments or performing routine maintenance on station equipment. It takes a complex array of machinery to keep people alive and well in orbit. Daily, each human breathes the equivalent of 0.9 kg. of liquid oxygen - enough air to fill a 3.5 cubic metre room - and drinks a total of 2.7 kg of water. To minimize on resupply needs, the ISS life-support systems are designed to recycle as much as possible. Waste water from urine and moisture condensed from the air is either purified and reused direct, or broken down by electrolysis to provide fresh oxygen. Carbon dioxide 'scrubbers' chemically remove that toxic gas from the air.

oxygen helps in breathing of the million cells in your body.Blood transfers oxygen to the cells & the cells can carry out their processes with help of oxygen.Since everything requires energy to carry on its processes,human require oxygen to carry out its process of living

Apart from production of red cells and oxygen & carbon dioxide balance, the bones are the organs where calcium and phosphorous are stored when  excess in the blood thereby maintaining homeostasis...

Homeostasis \nHomeostasis is the physiological process by which the internal systems of the body (e.g. blood pressure, body temperature, acid-base balance) are maintained at equilibrium despite variations in the external conditions. \nThe body can maintain the fluid levels using the kidneys, these organs filter out harmful chemicals and excess liquid into the bladder from which the urine is then expelled.  Body temperature is regulated somewhat by the skin, example, if you are hot you begin to sweat and this helps to cool the body, if you are cold you shiver this helps to raise, the body temperature.

Respiration removes carbon dioxide which, when in the body, forms carbonic acid in the blood. Too much carbonic acid and you will suffer from acidosis. In addition to keeping the blood at the correct pH, respiration supplies oxygen to the blood and tissues, such as muscle so that they too, can function correctly.\nSo, homeostasis is when all systems and fluids and tissues are "balanced", or in their correct working state. By removing carbon dioxide, respiration helps to keep the blood (and the body) in homeostasis.

Arteries are muscular blood vessels that carry blood away from the heart. They are contrasted with veins, which carry blood toward the heart.\n\nThe circulatory system is extremely important in sustaining life. Its proper functioning is responsible for the delivery of oxygen and nutrients to all cells, as well as the removal of carbon dioxide and waste products, maintenance of optimum pH, and the mobility of the elements, proteins and cells of the immune system. In developed countries, the two leading causes of death, myocardial infarction and stroke each may directly result from an arterial system that has been slowly and progressively compromised by years of deterioration.

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.

breathing, thought, eating, excersize, emotion, sickness, immunity and basically everything a human does would have some kind of chemistry involved considering we are multicellular organisms made up of many elements such as oxygen, calcium, carbon, nitrogen etc

Basically by osmosis. The cell absorbs nutrients and oxygen through the cell wall from the blood circulating in the capillaries. The oxygen is absorbed by the body in an exchange in the lungs and nutrients are absorbed through the small and large intestine and they all travel in the blood stream to the cells.
