The human body has a Skeletal system, Respiratory system, Digestive system, Integumentary system, Lymphatic system, Muscular system, Nervous system, Cardiovascular system, Reproductive and Urinary system, Endocrine system, so in all it has eleven (11) organ systems.
Our body’s significant functions are performed by the coordination of the various organs system mentioned above. The management is well-performed and in a rhythmic manner that if one lacks to perform their job on that particular time, the other organ put all the efforts to cover that issue. Therefore, homeostasis is the term used to describe such coaction, which is said as ‘the state of balance within the body.
This system includes our body’s bones and joints, which form the framework and give shape and support to it (body). The most critical role of the skeletal system is to provide protection of the delicate internal organs, as once they get injured, it’s hard to recover. For example, Skull protects the brain, the ribs guard the abdominal organs. This system is also helpful in the body’s movements and connects the muscles from one part of the body to other.
It is counted with the parts like Larynx, Pharynx, Lung, Trachea, Nasal Cavity. It is supportive in breathing. As when we inhale air or exhale it, it is done with the respiratory system. It also play role in speech and smell.
It includes the Liver, Esophagus, Oral cavity, Rectum, Anus, Small and Large Intestine. From the beginning with the mouth, which is used for the intake of food, till the removal of waste material and from identifying the proteins, vitamins, irons, and minerals for absorbing and using it in the growth of the body, the digestive system is active
Our body’s outer layer – the Skin, is a protective layer and thus acts as the barrier for harmful substances to enter the body. The skin also functions in maintaining the body’s temperature and feels the sense to touch, pleasure, and pain. The skin is the major exposed part that is likely to get wounds and injury, which may allow the infecting agents to enter the body.
Thymus, Lymphatic Vessels, Red Bone Marrow, Spleen, Thoracic Duct are the parts of this system and play the important role in improving the immune system and fighting against diseases and the agent causing them.
The muscular system comprises the Skeletal, Smooth, and Cardiac muscles. Skeletal muscles are also known as the voluntary muscles, that function as per the requirement of the body, the signals are sent from the brain via the nervous system, and the task is performed. Smooth muscles are also known as the involuntary muscles, they are found in such parts where the working of the muscles is throughout on active modes, like in the region of the heart, digestive tracts, etc. Cardiac muscles are present in the heart and thus circulate the blood throughout the body.
It has two parts – the Peripheral Nervous System (PNS) and the Central Nervous System (CNS). The PNS comprises all the nerves that are connected or interconnected in our body, while the CNS includes the spinal cord and brain.
This system comprises the various types of glands that perform different activities in our body, these glands are – Pituitary Gland, Thyroid Gland, Pineal Gland, Adrenal Gland, Pancreas, Ovary, and Testis. These glands secrete a chemical known as ‘hormones’. These hormones play a significant role in one’s growth, metabolism, and reproduction and also the maintaining the glucose level of the body.
The cardiac muscles’ role is to continuously and rhythmically perform their action, and that’s the reason, our Heart has such muscles, that pump blood, and with the help of arteries and veins transfer it to the all parts of the body. This cycle keeps on going as the deoxygenated blood gets oxygenated and send back.
This system varies in the male and female, as in the male it includes testis, prostate gland, ductus deferens, scrotum, penis, whereas in the female the reproductive system comprises of the uterus, vagina, mammary glands, fallopian tubes. The reproductive system plays a crucial role in creating the new human life, following the proper process of reproduction.
The organ system, that is regulating the excretion of waste material of the metabolism and other waste materials. It is also maintaining the fluid volume, concentrations of electrolytes, and the pH level of the body.
