How body systems work together chart

The human body contains trillions of cells, 78 different organs and more than 60,000 miles of blood vessels if you stretched them end-to-end. Incredibly, all of these cells, vessels and organs work together to keep you alive.

Each organ belongs to one of ten human body systems. These body systems are interconnected and dependent upon one another to function. Your heart does not beat unless your brain and nervous system tell it to do so. Your skeletal system relies on the nutrients it gains from your digestive system to build strong, healthy bones.

There are 10 body systems:

1. Circulatory
2. Respiratory
3. Nervous
4. Muscular
5. Skeletal
6. Digestive
7. Endocrine (hormones)
8. Lymphatic, or immune system
9. Reproductive
10. Integumentary (skin, hair)

A body system is a group of parts that work together to serve a common purpose. Your cardiovascular system works to circulate your blood while your respiratory system introduces oxygen into your body.

Each Body System Works with the Others

Each individual body system works in conjunction with other body systems. The circulatory system is a good example of how body systems interact with each other. Your heart pumps blood through a complex network of blood vessels. When your blood circulates through your digestive system, for example, it picks up nutrients your body absorbed from your last meal. Your blood also carries oxygen inhaled by the lungs. Your circulatory system delivers oxygen and nutrients to the other cells of your body then picks up any waste products created by these cells, including carbon dioxide, and delivers these waste products to the kidneys and lungs for disposal. Meanwhile, the circulatory system carries hormones from the endocrine system, and the immune system’s white blood cells that fight off infection.

Each of your body systems relies on the others to work well. Your respiratory system relies on your circulatory system to deliver the oxygen it gathers, while the muscles of your heart cannot function without the oxygen they receive from your lungs. The bones of your skull and spine protect your brain and spinal cord, but your brain regulates the position of your bones by controlling your muscles. The circulatory system provides your brain with a constant supply of oxygen-rich blood while your brain regulates your heart rate and blood pressure.

Even seemingly unrelated body systems are connected. Your skeletal system relies on your urinary system to remove waste produced by bone cells; in return, the bones of your skeleton create structure that protects your bladder and other urinary system organs. Your circulatory system delivers oxygen-rich blood to your bones. Meanwhile, your bones are busy making new blood cells.

Working together, these systems maintain internal stability and balance, otherwise known as homeostasis. Disease in one body system can disrupt homeostasis and cause trouble in other body systems. If you become ill with the AIDS virus that affects your immune system, for example, you may develop pneumonia in your respiratory system, a yeast infection in your reproductive system, Candida that affects your esophagus in your digestive system or the skin cancer known as Kaposi’s sarcoma.

The human body is composed of many parts. Each part of the body has a specific function. Scientists divide the human body into systems to better understand how its parts interact with each other, to function as a whole.

A body system is a group of body parts that work together to perform a certain job. For example, the skin, hair, and nails are part of a system called the integumentary system, which protects the body from its environment. The immune system is another example of a system that protects the body. It consists of a complex network of organs, tissues, and cells, such as white blood cells, that help the body recognize and destroy foreign substances and fight off infections.

Some body systems work together to complete a job. For example, the respiratory and circulatory systems work together to provide the body with oxygen and to rid the body of carbon dioxide. The lungs provide a place where oxygen can reach the blood and carbon dioxide can be removed from it.

Some body systems share a common organ that performs more than one job. For example, the pancreas serves both the digestive system and the endocrine system.

In the digestive system, the pancreas helps break down food into nutrients by secreting enzymes into the small intestine to digest fats, starches, and proteins. As part of the endocrine system, the pancreas produces two kinds of hormones--insulin and glucagon--to regulate the amount of glucose, or sugar, in the blood.

Glucose is the main source of energy for the body's cells. Insulin travels through the bloodstream to help cells remove glucose from the blood and use it. The hormone glucagon causes the liver to add glucose to the blood. Together the hormones insulin and glucagon--supplied by the pancreas--keep glucose in the blood at a healthy level.

Although scientists categorize groups of organs into different body systems, these systems do not work in isolation. A disorder in one system can cause other systems to break down.

For example, the pancreas may fail to produce enough of the hormone insulin. This causes the level of glucose in the bloodstream to rise, and a condition known as Type I diabetes mellitus results.

Other body systems, including the digestive, circulatory, and excretory systems, are affected by the disease. Symptoms include excessive urination, thirst, loss of appetite, poor circulation, and vomiting. If left untreated, coma and death can follow. Type I diabetes is managed by injections of insulin and small regularly spaced meals and snacks to keep the amount of glucose in the blood at a steady and normal level.

The human body is beautifully complex. Although each body system performs a different role, all the systems work together to keep the entire body healthy. Learning how these systems interact can help us understand how food, exercise, and disease affect more than just a single system.
