1. Body systems

2. Skeletal System
System- Provides shape and structure to the body. Allows for movement. Protects vital organs. Produces blood cells.
Organs- bones, ligaments, cartilage
Relationship with other organs-
Gives the skeletal muscles something to pull against to provide bodily movement
Medical Conditions-
Arthritis
Leukemia (could also be immune)
Osteoporosis
Rickets

3. Muscular System System- Allows movement of the body to provide heat
Organs- Smooth muscle, skeletal muscle, cardiac muscle, tendons
Relationship with other organs-
Urination is caused by the contraction of muscle surrounding the bladder
Contractions of the cardiac muscle in heart is responsible for the movement of blood throughout the circulatory system
Many muscles are attached to bones of the skeletal system to provide bodily movement
Medical Conditions-
Muscular dystrophy
Fibromyalgia
Myopathy
cramps and spasms
Tendonitis

4. Nervous System
System- Receives and interprets information for the bodies internal and external environments. Sends messages to the body about how to react to changes in the environment.
Organs- spinal cord, brain, nerves
Relationship with other organs-
Receives information in the form of electrical signals from all organs in the body
Has control over the functions of all organs in the body
Linked to every organ in the body through a network of nerves
Medical Conditions-
Alzheimer's disease
Epilepsy
Stroke
Parkinson's disease
Spina bifida

5. Endocrine System
System- controls body functions using chemicals messengers called hormones
Organs- adrenal gland, thymus, thyroid gland, pituitary gland, pancreas
Relationship with other organs-
Produces hormones that controls the growth of bones in the skeletal system
The hormones it produces are transported throughout the body by the circulatory system
Hormone production is dictated by signals received from the nervous system
Medical Conditions-
Cushing’s disease
Diabetes mellitus
Thyroid cancer
Addison's disease

6. Integumentary System
System- protects the body from foreign invaders by providing a tough protective layer. Helps maintain the body’s internal temperature. Protects against the sun’s UV radiation. Produces vitamin D.
Organs- nails, hypodermis, hair, dermis, epidermis
Relationship with other organs-
Works with the immune system to provide the body with the first layer of defense against disease causing pathogens.
Provides protection for the the organs of the digestive, respiratory, circulatory, urinary, and nervous systems (can also be skeletal or immune)
Works with the nervous system to control body temperature (sweating, goose bumps)
Medical Conditions-
Warts
Basal cell carcinoma
Eczema
Acne
psoriasis

7. Immune and Lymphatic System
System- helps fight off disease causing foreign invaders
Organs- lymph nodes, lymph vessels, white blood cells
Relationship with other organs-
Runs parallel to the circulatory system to transport disease fighting white blood cells
Medical Conditions-
Lymphomas
Splenomegaly
Multiple sclerosis (can also be considered nervous)
Tonsillitis

8. Respiratory System
System- brings oxygen into the body, gets rid of excess carbon dioxide
Organs- lungs, bronchi, nose, alveoli, trachea, diaphragm (also muscular), bronchioles
Relationship with other organs-
Smooth muscle in the diaphragm help control breathing (also muscular system)
Works with the circulatory system to provide oxygen to all the cells in the body and remove excess carbon dioxide
Medical Conditions-
Asthma
Bronchitis
COPD
Emphysema
Cystic fibrosis
Pneumonia

9. Circulatory System
System- Transports oxygen, waste, nutrients, hormones, hear, etc. around the body
Organs- veins, arteries, heart, capillaries, red blood cells
Relationship with other organs-
Works with the endocrine system to transport hormones throughout the body
Works with the lymphatic/immune system to transport white bloods cells to site of infection
Heartbeat is involuntary controlled by the nervous system
Works with the digestive system to absorb and deliver nutrients to the cells
Works with the excretory system to filter waste out of blood for removal
Works with the respiratory system to exchange oxygen and carbon dioxide
Medical Conditions-
Heart disease
Deep vein thrombosis
Atherosclerosis
Aneurism
Myocardial infarction

10. Excretory System
System- filters blood and rids the body of waste material. Maintains water and electrolyte balance in the body.
Organs- kidneys, urethra, ureter, bladder
Relationship with other organs-
Urination is caused by the contraction of muscle surrounding the bladder
Filters blood from the circulatory system of waste products so they can be removed from the body
Medical Conditions-
Acute renal failure
Nephritis
Cystitis
Urinary incontinence
Kidney stones

11. Digestive System
System- breaks down food into smaller molecules and absorbs these nutrients into the body
Organs- large intestine, small intestine, stomach, gall balder, esophagus, salivary glands, pancreas (also part of the endocrine), mouth, liver
Relationship with other organs-
Works with the nervous system to trigger appetite
Works with the muscular system to control the contractions of organs responsible for breaking down food
Works with the circularity system to deliver digested nutrients to cells throughout the body
Smooth muscle found in the esophagus, stomach, small intestine, and large intestine are responsible for the mechanical breakdown of food
Works with the circulatory system to provide essential nutrients for all organs in the body
Medical Conditions-
GERD
Irritable bowel syndrome
Crohn’s disease
Celiac disease

12. Reproductive System
System- produces sex cells; sperm (male) and eggs (females). Provides suitable environment for the development of unborn baby (females)
Organs- uterus, testes, ovaries
Relationship with other organs-
Works with the endocrine system to control the production of sperm (males) and eggs (females)
Requires the help of the muscular system during childbirth. Muscles surrounding the uterus contract to give birth.
Medical Conditions-
infertility
