What is this weird looking word mean?

"Homeostasis or homoeostasis is the property of a system in which variables are regulated so that internal conditions remain stable and relatively constant. Examples of homeostasis include the regulation of temperature and the balance between acidity and alkalinity (pH)."


Cardiovascular system

The cardiovascular system supplies oxygen and nutrients to our body by working with the respiratory system, circulatory system and the endocrine system. Working together they supply the body with oxygenated blood while at the same time taking deoxygenated blood back to the heart.

What does the blood have in it?

The oxygenated blood is rich with nutrients, antibodies, & oxygen. This blood comes out of the left ventricle.

While deoxygenated blood carries waste and carbon dioxide. This blood is pumped into the right atrium to the right ventricle to the lungs.

Muscular System

Muscular System
The muscular system works with the skeletal system to help the body move.

"The skeletal system makes up the framework of the body and allows us to move when our muscles contract. It stores minerals (e.g. calcium, phosphorous) and releases them into the body when they are needed. The skeletal system also protects internal organs and produces blood cells."

Digestive System

The digestive system is the system you can thank for getting all of the food and nutrients you eat into your body. "The digestive system works very closely with the circulatory system to get the absorbed nutrients distributed through your body. The circulatory system also carries chemical signals from your endocrine system that control the speed of digestion."


How does what you eat affect you?

Fatty Foods

"Other studies have suggested that long-term consumption of a high fat diet is associated with weight gain, heart disease and declines in cognitive function. But new research shows how indulging in fatty foods over the course of a few days can affect the brain and body long before the extra pounds show up."

One effect of eating fatty foods is your short term memory is not as sharp as it would have normally been if you had been eating a healthier diet.

Salty foods

Salty foods work on your kidneys making them hold more water. This extra water puts a strain on your kidneys, arteries, heart, & brain causing your blood pressure to rise.
