Human Body Systems

Circulatory System

• This is the system that circulates blood and lymph throughout the body. The heart is made up of four different blood-filled areas called chambers.
• These are the right and left atriums, and the right and left ventricles. While the aorta is the large artery that brings blood from the heart to the rest of the body.

Circulatory System

• Blood first enters the heart through the top right atrium here it is pumped down to the right ventricle, here it is pumped through the pulmonary arteries, to the lungs to be enriched with oxygen, they then enter the heart through the pulmonary veins and into the left atrium, here it is pumped in to your left ventricle where it is then pumped into your aorta to be spread to the entire body.

Respiratory System

• The respiratory system is the exchange of oxygen and carbon dioxide between an organism and its environment.
• This includes the nasal cavity, diaphragm, the pharynx, larynx, trachea, bronchioles, and lungs.

Respiratory System

• Oxygen enters the mouth and nose, it travels down the trachea, then moves into one of two bronchi that then delivers it to each lung while the diaphragm helps the lungs expand and fill with oxygen. The bronchi branch off into alveoli and then directly in to the bloodstream. As red blood cells drop off the oxygen they pick up the carbon dioxide that needs to leave the body. The carbon dioxide travels back out through to bronchi, trachea, and finally through to nose or mouth.

Digestive System

• The system of organs responsible for getting food into and out of the body and for making use of food to keep the body healthy. It includes the salivary glands, mouth, esophagus, stomach, liver, gallbladder, pancreas, small intestine, colon, and rectum.

Digestive System

• Food is placed in the mouth and chewed, and mixed with saliva from the salivary glands. The tongue directs the food as it is swallowed.The food travels to the esophagus and moves into the stomach., the food is mixed with acids that break its materials down.
• Once the food is broken down it enters the small intestine. In the upper part of the small intestine, chyme is present to further break down nutrients and neutralize some of the remaining stomach acid. The pancreas is also located here and adds several necessary digestive enzymes.The lower part of the small intestine is lined with millions of villi, which absorb nutrients out of the food, and into the bloodstream.Once most of the nutrients are removed, the remaining materials move to your large intestine. In the large intestine, most of the water and some compounds such as vitamins are removed. The large final section is called the colon.The mostly-dehydrated waste is pushed through the colon to the rectum and leaves the body.
