We kick off our journey through the organ systems of the body with the systems that literally breathes life into us. The respiratory system is responsible in handling the gas exchange of the body, keeping every cell in our body healthy by providing fresh supply of oxygen. There are two components of the respiratory system, the upper respiratory tract consisting of the nose through the larynx and the lower respiratory tract consisting of the trachea down to the ends of the lungs. Gas exchange occurs in the alveoli of the lungs and the capillaries, which then distributes the oxygen to the different parts of the body.
The digestive system is responsible in handling situations which involved the breakdown, assimilation and digestion of foods as well as the elimination of the residue. The digestive system employs a very long digestive tract, starting from the mouth down to the stomach, to the intestines and then ending up in the opening of the anus. The liver, the biliary system which includes the gall bladder and related ducts, and the pancreas are all associated parts of this system.
This system’s main goal is the excretion of waste from our body. But to have a more working definition of what the urinary system does, it is involved in efforts of the body to conserve water and maintain a neutral balance of acids and base in the body. The main functionaries of this system are the kidneys. Urine or residual fluid travels first through the ureters and ends up in a waiting chamber known as the bladder. Once the bladder reaches a certain point, it releases the stored residual fluid with what we refer to as the call of nature.
This is the body’s version of the military, aiming to protect the body against foreign invasion. This system is very important in keeping us healthy and able to withstand changes in weather and exposure to harmful microorganisms. There is an untold battle happening inside our body everyday and if you are healthy, then your immune soldiers are winning the battle. The bone marrow, thymus, the spleen, tonsils, lymph nodes, and lymphoid tissues are all part of the lymphoid system which is concerned with the protection of the body. This system which includes the diffuse collection of immune-related cells all over the body is tasked with resistance to invasive microorganisms and the removal of damaged or otherwise abnormal cells.
Female Reproductive System
The female reproductive system, to put it simply, is half of the reason why the population continues to swell. This system is concerned with our reproduction, the continuation of life. This system regulates the secretion of sex hormones, the production and the safe transportation of the ova, the accommodation of the male sex cells and guides them to the fertilization spot, maintenance of the developing embryo and also a makeshift mechanism for the sustenance of the newborn.
Male Reproductive System
The male counterpart to that of the female, this system is the other half to complete the only power man is capable off, the ability to propagate life. This system is responsible for secretion and regulation of the male sex hormones, the creation and formation of sperm cells and the transport of the germ cells to where they should be in the first place, the female genital tract.
Our understanding is relatively little compared to how complex our body works. Understanding the organ systems in our body is one of the key in trying to understand human nature. The body, on its own right, is a perfectly oiled machine but like any other machine, it does expose itself to some wear and tear and by understanding the role it plays in the body, we can be prepared to assist the ailing body system to still be able to attain optimum level of functioning.
