THE HUMAN BODY
Facts About the Human Body

Our bodies are made up of 11 different systems.
The body is the structure of a person and is made up of a head, neck, trunk; 2 arms, 2legs and 2feet.
Our bodies are composed of almost 5 1/2 liters of blood.
It also contains muscle, bone, water and connective tissues such as cartilage, ligaments and tendons.
C
onsists of your Skin, Hair and Nails
Integumentary System

The skeletal system is made up of bones, cartilage, ligaments and tendons
Skeletal System
Muscles provide movement of the body as a whole and of materials, maintenance of posture, heat production
Muscular System
The nervous system is your body's control system and is made up of the brain, spinal cord, and nerves
Nervous System
This system is the exchanging of gases that occur between the body's tissues and the external environment
RESPIRATORY SYSTEM
This system digests and absorbs nutrients from food taken into the body; it also moves food through the gastrointestinal tract
DIGESTIVE SYSTEM
This system helps to regulate and control many physical processes that happen in the body
ENDOCRINE SYSTEM
The urinary system eliminates waste from the body, in the form of urine.
URINARY SYSTEM
OUR AMAZING HUMAN BODY
Skin is the main organ of this system
Your skin has 4 basic functions: Protects against germs, protects important organs, waterproof and protects against UV rays
Three main layers of your skin are Epidermis, Dermis and Subcutaneous layer
Fun Facts About Your Bones
A newborn baby has around 350 bones in their body. As they grow, many of these bones will fuse together. An adult has approximately 206 bones.
Nearly half of the bones in your body are found in your hands and in your feet
Many bones start off as cartilage, which will gradually turn into solid bone. This process is called ossification.
The muscular system is made up of tissues that work with the skeletal system to control movement of the body
This system sends, receives, and processes nerve impulses throughout the body. Nerve impulses tell your muscles and organs what to do and how to respond to things in the environment.
There are three parts of your nervous system that work together:
Central Nervous System (CNS)- Brain and Spinal Cord
Peripheral Nervous System (PNS)- carries nerve impulses from the central nervous system to the muscles and glands
Autonomic Nervous System (ANS) - controls involuntary actions
Your body is made up of four main types of bones:
Long bones
Short bones
Flat bones
Irregular bones
Smooth, Skeletal and Cardiac are 3 types of muscle tissue.
Fun Facts About Your Muscles
It takes over 200 muscles working together to walk
Your body is made up of approximately 696 muscles
The Gluteus Maximus is the largest muscle in the human body. That's the muscle that you sit on :-)
The respiratory system includes the nose, trachea, and lungs
Fun Facts about your Respiratory System
When resting, the average adult breathes around 12 to 20 times a minute
Diseases of the lungs include: emphysema, asthma, tuberculosis, pneumonia and bronchitis
Each day, on average a person will breathe in around 11,000 liters of air
Fun Facts about your Nervous System
The Nervous System can transmit impulses as fast as 100 meters per second
The base of the spinal cord has a cluster of nerves, which are most sensitive
Neurons in the body can be as long as 3 feet in length
Parts of this system:
mouth
esophagus
liver
stomach
pancreas
gallbladder
intestines
rectum
anus
Fun Facts about your Digestive System
The small intestine makes up about two-thirds of the length of the digestive tract (about 22 feet long and 1 inch in diameter)
The digestive system causes more cancer deaths than any other organ system in the body
Flatulence or intestinal gas is a mixture of swallowed air and the gasses produced by the fermentation of bacteria in the gastrointestinal tract
Fun Facts about your Skin
Skin is the body's first line of defense against bacteria and viruses
You shed approximately 40 lbs of skin in a lifetime (GROSS!)
Each month, a person has a whole new layer of skin
Burns
Skin Cancer
Warts
Athlete's Foot
PROBLEMS
Fractures
Scoliosis
Osteoporosis
PROBLEMS
PROBLEMS
Muscle Strain
Bruise
Hernia
Muscular Dystrophy (inherited)

PROBLEMS
Parkinson's disease
Alzheimer's disease
Multiple Sclerosis
Cerebral Palsy
The endocrine system includes all of the glands of the body and the hormones produced by those glands.
This system consists of:
Hypothalamus
Pituitary gland
Pineal gland
Thyroid gland
Parathyroid gland
Adrenal
Pancreas
Gonads
Thymus
Fun Facts About Your Endocrine System
PROBLEMS
Type 1 and Type 2 Diabetes
Hyperthyroidism/Hypothyroidism
Precocious (early) Puberty
Diabetes was once diagnosed by tasting urine (gross!)
The pineal gland secretes melatonin which regulates our sleep patterns
The endocrine system is involved in almost all functions of the human body
MALE AND FEMALE REPRODUCTIVE SYSTEM
Fun Facts of the Female Reproductive System
Fallopian tubes are no wider than the head of a pin
The ovaries of a newborn baby girl contains almost 600, 000 immature eggs
The largest cell in the female human body is the ovum or egg present in the ovaries
Fun Facts About the Male Reproductive System
In an adult male, about 500 million sperm mature each day
The average life span of a sperm is about 36 hours
Problems of the Female Reproductive System
Endometriosis
Pelvic Inflammatory Disease
Infertility
Problems of the Male Reproductive Systems
Infertility
Epididymitis (an inflammation of the epididymis)
Cancer:
Prostate Cancer
Testicular Cancer
Penile cancer
Cancer:
Uterine Cancer
Ovarian Cancer
Breast Cancer
Cervical Cancer
The reproductive system allows humans to produce children
This systems contains these parts:
Female:
Uterus
Urethra
Fallopian Tubes
Ovaries
Vagina
Male:
Urethra
Seminal Vesicle
Epididymis
Penis
Prostate Gland
The kidneys remove waste from the blood.
This system includes two kidneys, two ureters, the bladder, two sphincter muscles and the urethra
PROBLEMS
Asthma Bronchitis
Emphysema Hayfever
PROBLEMS
Colon Cancer
Irritable Bowel Syndrome
Constipation
Diarrhea
Celiac Disease

PROBLEMS
Fun Facts About the Urinary System
CARDIOVASCULAR SYSTEM
PROBLEMS
Fun Facts About Your Cardiovascular System
The cardiovascular system is the body's main transport system
It is made up of a group of organs that transport blood throughout the body
The heart pumps the blood and the arteries and veins move it to other parts of the body
This system consists of your heart, blood and blood vessels
Heart Attack
Blood Clot
Arrhythmia
Coronary Artery Disease
The heart beats around 3 billion times in an average person's lifetime
Blood that contains a larger amount of oxygen will appear red. Blood that is poor in oxygen appears blue
The heart begins beating at four weeks after conception
Kidney Stones
Urinary Tract Infection
Bladder Infection
The average person can pass up to 2 liters of urine in 24 hours
Certain foods can also influence the color and smell of urine
A normal bladder completely empties every time you go to the bathroom
