Dear student 
There are major 5 organ system in human body. They are nervous system, excretory system, circulatory system, digestive systems and reproductive system. 
Digestive System -- This system is responsible for breaking down all of the macromolecules into simple components for the body to use. The 4 macromolecules includes proteins, carbohydrates, lipids and nucleic acids. The parts of the digestive system include the mouth, salivary ducts, esophagus, stomach, duodenum, small intestine, large intestine, rectum and anus. 
Nervous System -- The nervous system consists of two parts one which is the PNS (includes spinal nerves), and the CNS (spine and brain). This system initiates the flight and fight response during extreme stress, and also will perform reflex arcs to various stimuli.
Reproductive System -- produces off springs. Contains the male and female systems.

Excretory System -- this is responsible for the excretion of nitrogenous wastes such as urea and urine. This system includes nephrons, kidneys, ureters, urinary bladder, urethra.

The pulmonic one carries it around the upper half of the body, and the systemic system carries it through the lower extremities and the high parts of the body.

Beside above there are other systems as well like:

Endocrine System -- this system includes the exocrine and endocrine hormones that target different systems. This system is a lot slower than that of the nervous system. The organs of the endocrine system is pineal gland, hypothalamus, thymus, parathyroid, thyroid, pancreas, ovaries, adrenals, testes.
Integumentary System -- this is the system that provides protection to the body itself. The parts of this system are: skin, hair, finger and toe nails
Lymphatic/Immune System -- these are the systems that help with the protection within the inside of the body. The lymphatic system includes all of the lymph nodes, thoracic duct, lymphatic duct, spleen, etc. The Immune system includes antibodies, antigens, immunoglobulins, helper cells etc.
