Your Body is the only Lifetime & trustworthy possession you have. Understand, Realize and accept it.
It’s needless to say or talk about the importance of a good health but there is
the need to get back to our school days and recollect what we learnt about our
body.
Our body and its parts are our life time acquaintances.
Are we Aware???
Lets BEFRIEND our BODY & It’s most important Parts and greet them TODAY!!!
The basic parts of the human body are
• The Head
• Neck
• Torso
• Arms
• Legs
Body Systems- Our bodies consist of a number of biological systems that carry out specific
functions necessary for everyday living.
- Circulatory system
- Its job 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
- It 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
- It consists of eight major glands that secrete hormones into the blood. These
hormones, in turn, travel to different tissues and regulate various body
functions, such as metabolism, growth and sexual function.
- Immune system
- It’s 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
- It includes lymph nodes, lymph ducts and lymph vessels and also plays a role in
the body's defenses. Its main job is to make and move lymph, a clear fluid that
contains white blood cells, which helps the body fight infection. The lymphatic
system also removes excess lymph fluid from body tissues and sends it to the
blood.
- Nervous System
- It controls both voluntary action (conscious movement) and involuntary
actions (breathing), and sends signals to different parts of the body. The
central nervous system includes the brain and the spinal cord. The peripheral
nervous system consists of nerves that connect every other part of the body to
the central nervous system.
- Muscular System
- It consists of about 650 muscles that assist in movement, blood flow and other
body 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
- It allows humans to reproduce. The male reproductive system includes the
penis and the testes, which produce sperm. The female reproductive system
consists of the vagina, the uterus and the ovaries, which produce eggs. During
conception, a sperm cell fuses with an egg cell, which creates a fertilized egg
that implants and grows in the uterus.
- Skeletal System
- It supports our bodies which consist of 206 bones that are connected by
tendons, ligaments and cartilage. It 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.
- Respiratory System
- It allows us to take in vital oxygen and expel carbon dioxide in a process we call
breathing. It mainly consists the trachea, the diaphragm and the lungs.
- Urinary System
- It 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
- It is the body's largest organ. It protects us from the outside world and is our
first defense against bacteria, viruses and other pathogens. It also helps
regulate body temperature and eliminate waste through perspiration. The
integumentary system includes Skin, hair and nails.
Humans have five vital organs that are essential and important for survival.
The human brain is the body's control center, receiving and sending signals to
other organs through the nervous system and through secreted hormones. It is
responsible for our thoughts, feelings, memory storage and general perception
of the world.
The human heart is a responsible for pumping blood throughout our body.
The job of the kidneys is to remove waste and extra fluid from the blood. The
kidneys take urea out of the blood and combine it with water and other
substances to make urine.
The liver has many functions, including detoxifying of harmful chemicals,
breakdown of drugs, filtering of blood, secretion of bile and production of
blood-clotting proteins.
The lungs are responsible for removing oxygen from the air we breathe and
transferring it to our blood where it can be sent to our cells. The lungs also
remove carbon dioxide, which we exhale.
- Amusing Truth Of Human Body
-
 |
The human body contains nearly 100 trillion cells. |
|
The average adult takes over 20,000 breaths a day. |
|
Each day, the kidneys process about 200 quarts (50 gallons) of blood to
filter out about 2 quarts of waste and water |
|
Adults excrete about a quarter and a half (1.42 liters) of urine each day. |
|
The human brain contains about 100 billion nerve cells |
|
Water makes up more than 50 percent of the average adult's body
weight |
