The digestive respiratory and cardiovascular system

Gas Exchange — A vital life-sustaining process where we inhale oxygen O2 and exhale carbon dioxide CO2 [1, 2]. As each and every cell in the body needs O2 to live, humans cannot go without it for more than a few minutes [3]; so, the respiratory system is active all the time. High levels of CO2 in the blood decreases the pH level increases the acidity of the blood, so getting rid of it helps maintain the acid-base balance [49]. Speech Production — Inhalation is the first step of speech production, with the next two steps being sound production through the vocal folds around the larynx phonationand forming the words or sounds with the vocal folds, mouth, nose, tongue, and jaw articulation [50].

Your digestive tract converts complex carbs, like the starch in bread, into sugar, which you can use for energy.

Your circulatory and digestive systems do not directly convert food into energy, but they process and circulate nutrients so your cells can use them for fuel. Video of the Day Food and Energy The foods you eat supply carbohydrates, proteins or fats -- and many foods contain a mix of all three.

These three macronutrients serve as your main energy source.

Digestive System Anatomy

Carbs and proteins each contain 4 calories per gram, while fat is higher in calories, at 9 per gram. Each type of macronutrient undergoes different processing in your body and has unique pathways your body uses to turn them into usable energy.

The Preferred Source of Energy Your body -- especially your muscles -- prefers to run on carbs, and sugar is the sole source of energy for your brain. After a meal, your digestive tract breaks carbohydrates down into simple sugars, like glucose. From there, the glucose gets absorbed into your bloodstream, and your circulatory system distributes it throughout your body, allowing your tissues to take up the sugar to use for energy.

A Concentrated Energy Source Fat is the most efficient way to store excess energy since it has a higher energy density than proteins or carbs.

Most of the fat in food is found in the form of triglycerides, which contain three fatty acids bound together with a glycerol backbone. Your digestive tract breaks triglycerides down into individual fatty acids for absorption. Your digestive system breaks protein down into its individual components, called amino acids, and your cells and tissues use amino acids to make new cellular proteins.The Alimentary Canal.

What Does the Respiratory System Do: Its Parts and Their Functions

In a recent article titled “Digestive System Overview“, we discussed the six processes of digestion. We also discussed the two main divisions of the digestive system, organs within the alimentary canal and accessory digestive organs.

The digestive tract is dependent upon the respiratory system, because your digestive tract functions by using muscular contractions to break up food and move it along the tract.

Smooth muscle in the stomach churns food into a liquid, and contractions of the intestine move food through the system. The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body.

Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract (GI tract).
