Transcript of The Human Body

The Human Body By. Kodie Coyne, and Trystan Williams The Nervous System Made up of the brain, spinal cord, and the peripheral nerves. The nervous system is a complex system of nerves that led from the brain to the rest of the body, to control the body. Degeneration- causes worsening in the bodily functions
Structural defects- includes birth defects, missing limbs
Axson- a digestion disease.
Alzheimer's- when there are tangles or plaques in the brain it causes memory loss, confusion, mood swings and more. it is untreatable, and the cause is still unknown. Disorders of the Nervous System- Degeneration,Structural defects, Axson, Alzheimer's. Lymphatic system (A.K.A the immune system) It Is a network of special cells, proteins tissues and organs The immune system has cells called memory cells, the memory cells are the part of the immune system that remember a virus and get rid of it quickly the next time it is in the body It's mostly made of white blood cells Disorders or the immune system-
-Autoimmunity
-Juvenile Onset Diabetes
-Hypersensitivity
-And a lot more Autoimmunity- When the immune system attacks your body
instead of germs. No germs are produced for the immune Juvenile Onset Diabetes- Caused by the immune system
attacking the pancreas that produces insulin Hypersensitivity- Immune response that
damages the body’s own tissues Digestive System Made up of the oral cavity, esophagus, stomach,
small intestine, and the large intestine. A human digestive system is around 9 meters long. A healthy digestive system takes 24-72 hours to fully
digest and dispose of the food going through it Oral cavity- Contains the teeth, gums, and tongue.
Esophagus- The throat and tube that food, and water go to the stomach by. j Stomach- Helps break down foods, to small particles.
Small intestine- Further breaks down food particles after the stomach, and absorbs nutrients. Large intestine- the large intestine is another continuation of the digestive process, where the food is still being broken down and digested, and more nutrients are absorbed into the body. Acid reflex (A.K.A heartburn)- occurs when the stomach acid backs up into the esophagus giving a burning feeling in the chest. Ulcers- happen when a gastros juice burns a hole in the lining of the stomach.
dysentery- happens when bad foods are eaten then cause a The Reproductive System The reproductive system is a group of organs
that is located in both males and females. Included in this system is the gender-specific
sex organ (vagina in women; penis in men) As well as a variety of other organs that work together to reach a common goal, to reproduce. The functions of the reproductive system includes sexual intercourse, arousal, menstrual cycles, puberty, ovulation and pregnancy. Mastitis is painful swelling and redness in the breast. It is especially common among women who are breastfeeding. While it is most common in just one breast it can occur in both. Ejaculation occurs when a man reaches sexual climax and semen is ejected from his penis. Premature ejaculation is:

-Ejaculation occurs before the man wishes it to occur.

-Ejaculation occurs too quickly to sexually satisfy his partner An ovarian cyst is a fluid-filled sac in the ovary. During the menstrual cycle, it is normal for a cyst to develop. Most cysts are small and benign (not cancer) and go away on their own. Larger cysts can cause pain and other problems. Mastalgia is breast pain. There are two types of mastalgia, cyclical and noncyclic. Cyclical breast
pain is most often associated with menstrual
periods. Noncyclic pain does not vary with the menstrual cycle Endocrine System The system of glands that produce
endocrine secretions that help to
control bodily metabolic activity The Major parts of the endocrine system are hypothalamus, pituitary, thymus, and thyroid The parathoid, adrenals, pancreas,
ovaries, and testes are some more. DIABETES MELLITUS:The pancreas
does not secrete enough insulin DWARFISM: The anterior pituitary does
not release enough growth hormone SADS (Seasonal Affective Disorder): Pineal gland behind the eye releases too much melatonin. DIABETES INSIPIDUS: Posterior pituitary does not make enough ADH or its effects are blocked, ADH helps absorb water in the kidneys. Circulatory System The system that circulates blood
and lymph through the body. Consisting of the heart, blood vessels, blood,
lymph, and the lymphatic vessels and glands. The main parts of the circulatory system are
the heart, the blood vessels, the blood. Trauma– Penetrating trauma such as a
knife wound may damage the blood vessel. Vascular Malformations – When an abnormal connection exists between the veins and arteries, excess blood is shunted through these small vessels, which may become large and produce symptoms. Aneurysms – an aneurysm is a localized weakness of the vessel wall that results in an isolated expansion of the vessel, like a balloon popping up. Muscular System The muscular system is the anatomical
system of a species that allows it to move. The muscular system in vertebrates is controlled through the nervous system, although some muscles (such as the cardiac muscle) can be completely autonomous. These are the 12 main muscles
in a human body:
latissimus dorsi, trapezius, 
eltoid, gastrocnemius,
pectorals, biceps, 
triceps, external oblique, 
abdominals, gluteus maximus, 
hamstrings, quadriceps.  Muscular dystrophy- Is a genetic
disease that damages muscle fibers. Cerebral palsy- Impacts posture,
balance and motor functions. Myasthenia gravis is a chronic autoimmune disease that results in muscle weakness and fatigue. Skeletal System The hard structure (bones and cartilages) that provides a frame for the body of an animal The adult human body has 206 bones. An infant may have from 300-350 bones at birth. Some of these fuse together as the infant grows. Some of the most know
bones in the body are
the tibia, femur, and hip. Low bone density and osteoporosis- Makes
your bones weak and more likely to break. Bone disease can make bones easy to break Bones can also develop cancer and infections The skin and its appendages. Every month you have a whole new layer of skin. The appendages a your
hair and your nails. You will shed 40lbs of skin in a lifetime. The average amount of head hair is 120,000. Rash: A rash is a skin condition characterized
by the color change and texture of skin. Acne: Acne is an inflammatory skin
condition caused by changes in the oil
glands, clogged pores and bacteria Respiratory System The system for taking in oxygen and giving off carbon dioxide; in terrestrial animals this is accomplished by breathing Consists of the nostrils, Trachea
Bronchi, Lungs, Alveolus, Diaphragm

An average person breathes in the equivalent
of 13 pints of air every minute Approximately, 1500 miles of airways
are present in human lungs Asthma is a chronic condition of the airways or tubes of the lungs. It narrows the airways and make it difficult to breathe The flu (also called influenza) is a viral infection. It affects the respiratory system. It can cause mild-to-severe illness, and sometimes it can lead to death Integumentary System Excretory System The excretory system is a passive biological system that removes excess, unnecessary or dangerous materials from an organism The excretory system consists of the Bladder, Kidneys, Aorta, Ureters, Rectum, and the Nose.
The average person pees about 3000 times a year The average adult bladder can
hold 16-24 ounces of urine. The inflammation of the mucous membranes of the bronchi in the lungs is called bronchitis. Formation of crystals of calcium, uric acid
or struvite stones result in kidney stones. THE END
