Circulatory system
Consists of a series of connected organs that together, allow the body to break down and absorb food, and remove waste.
It includes the mouth, esophagus, stomach, small intestine, large intestine, rectum, and anus.
The liver and pancreas also play a role in the digestive system because they produce digestive juices.
Digestive system
Consists of eight major glands that secrete hormones into the blood.
These hormones, in turn, travel to different tissues and regulate various bodily functions, such as metabolism, growth and sexual function.
Endocrine system
The body’s defense against bacteria, viruses and other pathogens that may be harmful.
It includes lymph nodes, the spleen, bone marrow, lymphocytes (including B-cells and T-cells), the thymus and leukocytes, which are white blood cells.
Immune system

includes the brain and spinal cord.
Nervous system
consists of about 650 muscles that aid in movement, blood flow and other bodily functions.
Muscular system
consists of 206 bones that are connected by tendons, ligaments and cartilage.
it’s also involved in the production of blood cells and the storage of calcium.
Skeletal system
allows us to take in vital oxygen and expel carbon dioxide in a process we call breathing. It consists mainly of the trachea, the diaphragm and the lungs.
Respiratory system
helps eliminate a waste product called urea from the body, which is produced when certain foods are broken down.
The whole system includes two kidneys, two ureters, the bladder, two sphincter muscles and the urethra.
Urine produced by the kidneys travels down the ureters to the bladder, and exits the body through the urethra.
Urinary system
is the body’s largest organ. It protects us from the outside world, and is our first defense against bacteria, viruses and other pathogens.
