The Human Body Systems: Overview, functions and anatomy

The human body has a collective number of biological systems which carry out the specific functions that are necessary to everyday living of human body.

The group of organs and tissue form the body system that perform various functions of human body.

Some organs may serve more than one function of different systems and some serve only one body system.




There  are various different functions which are necessary for an organism to be able to survive and reproduce.

Here we will focus on the systems of human body and the brief explanation will also discuss in this article :-

Functions of different body systems

• Oxygen for use in cellular , and excrete waste carbon dioxide.
• Must be able to ingest and process food to obtain sugars and other nutrients.
• The body must transport necessary substances, such as oxygen and nutrients, to all cells.
• Clear toxic waste products from the body.
• Respond to the environment.
• Protect the body’s organs from the environment.
• Must be able to fight infections.
• For a species to survive, its individuals must be able to reproduce.

Below, we’ll see how our organs and tissues work together as body systems to perform their functions :-

1.) Skeletal system

The skeletal system is the body system composed of bones and cartilage and performs the following critical functions for the human body:

• supports the body
• facilitates movement
• protects internal organs
• produces blood cells
• stores and releases minerals and fat

2.) Muscular system

• The muscular system is composed of different types of muscles which provide motor power for movers of body parts .

3.) Nervous system

• The nervous system is composed of brain ,spinal cord , nerves and nerve ending. It help in control and coordination of all body function.
• It allows us to sense stimuli such as light, sound, smell, and touch from our environment.
• It also allows rapid communication of stimuli within our body, such as sensations of pain, illness, and wellness.

4.) Respiratory system

• The respiratory system helps in gas exchange between cells and the environment. Includes trachea, nose ,bronchi, bronchioles, alveolar sacs , alveoli .

5.) Cardiovascular system

• The cardiovascular system consists of the heart, blood vessels, and blood.
• This system has three main functions: Transport of nutrients, oxygen, and hormones to cells throughout the body and removal of metabolic wastes (carbon dioxide, nitrogenous wastes).

6.) Lymphatic system

• • The lymphatic systems the system of vessels, cells, and organs that carries excess fluids to the bloodstream and filters pathogens from the blood.

• It consist lymph vessels ,central lymphoid tissue ,peripheral lymphoid organs , lymphocytes.
• The main function of drainage of body fluid and protection.

7.) Digestive system

• The digestive system consist alimentary canal and it’s accessory organ i.e oral cavity, small intestine, large intestine, anus and other some organs are  liver, pancreases, salivary glands, teeth and tongue.
• The function of the digestive system is to break down the foods you eat, release their nutrients, and absorb those nutrients into the body.

8.) Urinary system

• The urinary system consist kidneys , ureters , urinary bladder and urethra.
• The urinary system has roles of cleansing the blood and ridding the body of wastes probably come to mind.
• However, there are additional functions are regulation of pH, a function shared with the lungs and the buffers in the blood.

9.) Male Reproductive System

• The structures of the male reproductive system include the testes, the epididymitis, the penis, and the ducts and glands that produce and carry semen.
• Sperm exit the scrotum through the ductus deferens, which is bundled in the spermatic cord.
• The seminal vesicles and prostate gland add fluids to the sperm to create semen.

10.) Female reproductive system

• The female reproductive system consist Uterus, Ovaries, Vulva, Labia, Clitoris and the main function of female reproductive system is the formation of eggs and bearing foetus during development.

11.) Integumentary system

• The integumentary system refers to the skin and its accessory structures, and it is responsible for much more than simply lending to your outward appearance.
