Human Body
systems
Circulatory system
The job of the circulatory
system is to move blood, nutrients, oxygen, carbon dioxide, and hormones,
around the body. It consists of the heart, blood, blood vessels,arteries and
veins.
Digestive system
The digestive 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.
Endocrine system
The endocrine 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.
Immune system
The Immune system is 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.
Lymphatic system
The lymphatic system includes lymph nodes, lymph ducts and lymph
vessels, and also plays a role in the body's defenses. Its main job is to make
is to make and move lymph, a clear fluid that contains white blood cells, which
help the body fight infection. The lymphatic system also removes excess lymph
fluid from bodily tissues, and returns it to the blood.
Nervous
system
The nervous system
controls both voluntary action (like conscious movement) and involuntary
actions (like breathing), and sends signals to different parts of the body. The
central nervous system includes the brain and spinal cord. The peripheral
nervous system consists of nerves that connect every other part of the body to
the central nervous system.
Muscular system
The body's muscular
system consists of about 650 muscles that aid in movement, blood flow and other
bodily functions. There are three types of muscle: skeletal muscle which is
connected to bone and helps with voluntary movement, smooth muscle which is
found inside organs and helps to move substances through organs, and cardiac
muscle which is found in the heart and helps pump blood.
Reproductive system
Skeletal system
Our bodies are supported
by the skeletal system, which consists of 206 bones that are connected by
tendons, ligaments and cartilage. The skeleton not only helps us move, but it's
also involved in the production of blood cells and the storage of calcium. The
teeth are also part of the skeletal system, but they aren't considered bones.
Reproductive system
The respiratory 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.
The urinary 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.
Integumentary
system
Who
controls the above systems in our body? Do we
control them? We even don't know which organ of our body is where.
Clearly, random events, human
beings and technology cannot produce such an astonishing work. This fact has
been scientifically proven. This amazing work in our bodies belongs to Allah,
Whose might makes all things according to His will.
Allah maintains countless balances in our body at every second,
without our ever being aware of them.
Almighty
Allah controls our these system, from our birth to our death.
We must be
grateful to him every day, at every moment.
