Body Systems

By: Sophie Schulze

Skeletal

Parts of the system: Bones, joints, tendons, ligaments, cartilage.


Other systems: Muscular, nervous, digestive, circulatory, respiratory.


Purpose of the system: The body has it to give it shape and support. It helps out other body systems by protecting the body and producing blood cells.


Potential infections and diseases: Osteoporosis (fragile bones), Leukemia (cancer of white blood cells),


Interesting facts: Smallest bones found in your body are in your ear. Over half the body's bones are in the hands and feet.

Muscular

Parts of the system: Muscles(skeletal, smooth, cardiac), bones, tendons.


Other systems: Nervous, skeletal, respiratory, circulatory, digestive.


Purpose of the system: Movement of the body.


Potential infections and diseases: Muscular dystrophy (imbalance, immobility, weakness), Cerebral Palsy(affects posture, balance, and motor functions)


Interesting facts: Muscles make up 40% of your total body weight. It takes half as long to gain muscle than to lose it.

Respiratory

Parts of the system: Nose/mouth, pharynx/throat, epiglottis trachea(windpipe), larynx(voice box), main stem, bronchi, bronchiole, alveoli.


Other systems: Nervous, circulatory, skeletal, digestive, muscular.


Purpose of the system: To get oxygen into the body and to get carbon dioxide out of the body. (helps to balance the amount of oxygen and carbon dioxide gasses in the body)


Potential infections and diseases: Common cold, Sinusitis, Pharyngitis, Epiglottis.


Interesting facts: The right lung is slightly larger than the left. " The surface area of the lungs is roughly the same size as a tennis court."- Amazing Facts about the. Respiratory - Amazing Facts. N.p., n.d. Web. 12 May 2017.

Digestive

Parts of the system: Mouth, epiglottis, esophagus, stomach, small intestines, large intestines, rectum, anus.


Other systems: Nervous, muscular, circulatory, respiratory (for oxygen for the organs)


Purpose of the system: Take nutrients from foods and take them to cells. Gets rid of food waste materials.


Potential infections and diseases: Cirrhosis; A degenerative disease of the liver. Dysphagia; Difficulty swallowing.


Interesting facts: Muscles contract in waves to move the food down the esophagus. The esophagus is approximately 25cm long.

Circulatory

Parts of the system: Blood, blood vessels, heart.


Other systems: Nervous, digestive, respiratory, muscular, urinary, skeletal, immune.


Purpose of the system: Carries nutrients (from digested food) to all cells in the body. Oxygen is carried from the lungs to all the other cells and exchange carbon dioxide. This carbon dioxide and other waste materials are carried back to the organs which then remove them from the body.


Potential infections and diseases: Coronary artery diseases: clogs up the arteries that are supplying the heart. Heart failure: The failure of the heart.


Interesting facts: The heart beats about 3 billion times in the average person's life. About 8 million blood cells die in the human body every second, and the same number are born each second.
