It is important for us to eat, because our body needs the nutrients. You need food to provide energy for it, nutrient are important because they enable your body to move, grow, and maintain homeostasis.

Some of the nutrients you body needs include, protein, carbohydrates, fats, and water. It may not seem like water is an important nutrient, but it is necessary for all living things.

Living organisms use matter and energy to create a wide range of organic molecules. Such as proteins, carbohydrates, lipids, etc.
As i said before, proteins are one of the most important nutrients your body needs, and it is very essential, because it is the material your body uses for growth and repair.

WHY DO WE BREATHE?

The respiratory system is the body system that functions to get oxygen from the environment, and removes carbon dioxide and other waste products from your body.

The respiratory system gets oxygen and removes carbon dioxide.
A:Your body needs oxygen
-Oxygen is used to release energy
-Oxygen is in air you breathe.

B.Structures in the respiratory system function together, like the nose, throat, trachea, and most importantly the lungs.
In conclusion, the simplest explanation for us to eat and breathe, is because we do it to live

THE BRAIN AND HOW IT CONTROLS THE CIRCULATORY SYSTEM.
The nervous system and the circulatory system are connected through the organ and body function control. Without messages from the brain, none of the systems would be able to work. Heart function and fluid circulation are triggered by the nervous system. So basically, the brain tells a nerve called the vagus nerve, which controls the pumping of the heart to circulate blood. so when the heart pumps, it circulates blood through the blood passage ways around the body, and to the organs.

THE BRAIN AND HOW IT CONTROLS THE DIGESTIVE SYSTEM.
The digestive system is controlled by the autonomic nervous system, which means when we eat food, we don't want to think about it. The ANS Controls the various digestive functions, such as releasing saliva when the food is put into the mouth . There are two groups of nerves which controls the digestive system. There are nerves that control esophagus, stomach, small intestine, and large intestine, and the other group controls the release of substances that speed up or slow down the digestion, absorption, secretion and movement of food along your digestive tract.

THE BRAIN AND HOW IT CONTROLS THE RESPIRATORY SYSTEM.
When you don't have enough carbon dioxide or oxygen in your body, the nervous system will tell the respiratory system how fast or how slow to breathe, autonomically.
THE BRAIN AND HOW IT CONTROLS THE MUSCULAR SYSTEM.
When the brain wants a certain body part to move, it sends a message to the neuron that's connected to Th body part, through multiple other neurons, and when it finally gets to the body part, a shock-like sensation is applied to it, which causes it to move.

THE BRAIN AND HOW IT CONTROLS THE SKELETAL SYSTEM.
-The bones provide calcium for the proper functioning of the nervous system.
-the skull protects the brain from injury, and the vertebrae protects the spinal cord from injury,

The connection between the Skeletal and Digestive system.
The skeletal system cannot produce its own calcium to strengthen itself. It depends on the digestive system. When a person eats food that contains calcium, the body breaks the food down into smaller molecules that can be absorbed by the body into the bloodstream.

The connection between the Skeletal and Digestive system.
With the aid of the circulatory system, the smaller molecules of calcium and phosphorus are then delivered into the bone tissues that need them for repair and to strengthen themselves.

The medical scenario I chose is anxiety.

How anxiety affects your respiratory system.
In the respiratory system, anxiety leads to hyperventilation, or overbreathing, which reduces the carbon dioxide in the blood, with symptoms of "air hunger," deep sighs, and pins-and-needles sensations.

How anxiety affects your nervous system.
Through changes in the central nervous system, the anxious person is generally more apprehensive, aroused, and vigilant, feeling "on edge," impatient, or irritable. He may complain of poor concentration, insomnia, and fatigue.

How anxiety affects your nervous system.
Anxiety activates the autonomic nervous system - the flight or fight response - which can express itself through a number of different physiological (and generally unpleasant) bodily symptoms including panic attacks, fast pulse, palpitations, shallow breathing, shortness of breath, and chest pain/tightness.

Some other symptoms:
Sweating, choking, headaches, insomnia, irritability, uncontrollable muscle tension/twitches, trembling, feeling faint/unreal, tingling in hands/arms/legs, tightness in throat, dry mouth, problems with speech, fear of dying, going mad and losing control.

Research tells us that most people have suffered some form of panic attack and experienced symptoms similar to the above at some time in their life.
