Genesis 1:27 Man is created in the image of God

 Circulatory system ◦ Transports blood through the body ◦ 4 main functions:  Fuel to the body  Waste to the liver and kidneys  Transport cells to fight disease  Transport hormones through the body

 Organs in the Circulatory System ◦ Heart – pumps blood ◦ Arteries – carry oxygenated blood away from the heart ◦ Veins – take blood back to the heart ◦ Capillaries – carry blood from the arteries to the cells

 Common Problems with Circulatory System ◦ Anemia – shortage of red blood cells ◦ Leukemia – form of cancer the effect white blood cells

 Group of passages that exchanges gases in order for the body to function properly  Main organ: Lungs take air in and exchange gases with the blood ◦ Blood takes oxygen to the body (inhale) ◦ Then carries away carbon dioxide (exhale)

 Problems with Respiratory System ◦ Common cold – effect ability to exchange gases efficiently ◦ Pneumonia- infection of the lungs causing difficulty in breathing ◦ Asthma – passages in the lungs swell and shrink making it difficult to breathe

 The combination of joints and connecting tissues (your body has 206 bones) ◦ This system functions as a unit to protect your body and move your body. It also stores substances your body needs

 Problems ◦ Scoliosis – curvature of the spine ◦ Bursitis – inflammation of the bursa sac which are located between bones ◦ Arthritis – inflammation of joints ◦ Injuries (fractures, dislocations, sprains)

 The group of tissues that makes your body parts move (over 600 muscles) ◦ Muscle Tissue is either voluntary (you control) or involuntary (do not control)

 Problems ◦ Strain – overworking of muscle ◦ Cramp – muscle will not relax ◦ Bruise – broken blood vessels create a hematoma (bruise) ◦ Pull or tear of a muscle

 Organs that take in food and break it down

 Problems ◦ Indigestion – food is not totally digested ◦ Nausea – motion, drugs, food contamination trigger vomiting center of the brain ◦ Ulcer – sore in the lining of the stomach

 To excrete (get rid of) waste from the body  Major Parts ◦ Urinary tract – expels liquid waste ◦ Large intestine – made up of several parts, but both liquid and solid waste pass through the 2.5 inch, 5 foot long intestine (large in diameter, not length when compared to small intestine)

 Problems ◦ Constipation – difficulty in passing solid waste ◦ Diarrhea – opposite of constipation, solid waste is loose and full of liquid ◦ Flatulence – “Gas”

 Skin, hair, nails, sweat glands, oil glands  The skin is the largest organ of the body and provides protection and regulation of body temperature

 Problems ◦ Warts – small growths on skin caused by a virus ◦ Calluses/corns – build up of thickened skin caused by friction ◦ Cold Sores – caused by a virus ◦ Skin Cancer – typically caused by overexposure to the sun

 To fight of intruders in your systems  Acts a defense mechanism against germs/diseases ◦ Your body has some natural immunities that you are born with ◦ Some immunities your acquire by being exposed to intruders

 Problems ◦ Allergies – person has become hypersensitive to an allergen ◦ HIV – the disease that causes AIDS weakens the body’s ability to fight of disease

 To maintain a stable internal environment through controlling the body parts so that they work as one flowing unit  Impulses can travel through your nervous system at a rate of 350 feet per second

 Problems ◦ Pinched nerve – when a part of the spine becomes displaced causing a squeeze on a nerve ◦ Infections – polio, rabies ◦ Epilepsy – brain disorder that causes a rapid firing of nerve actions

 The glands of the endocrine system secrete hormones to send messages to the cells in the body via the blood  Problems ◦ Malfunctioning pituitary gland – releases too little or too many hormones ◦ Thyroid glands – same as above ◦ Diabetes – cannot process sugar properly

 God’s creation for the continuation of the human race  Main Organs ◦ In Males, the reproductive organs lie outside the body  testes- produces sperm  Problems – testicular cancer

 In Females, the reproductive organs lie within the body ◦ Ovaries – organs that store eggs for reproduction ◦ Eggs are release every month into the uterus, if sperm meets this egg, a pregnancy may occurr ◦ Problems – premenstural syndrome (PMS) uncomfortable condition that includes moodiness due to headaches, cramps, tension, and depression ◦ Cancer of female organs
