Digestive System

3. Digestive system
What does it do? Digestion is the process by which food and drink are broken down into their smallest parts so the body can use them to build and nourish cells and to provide energy.
Common problems/injuries? Heartburn (acid reflux), ulcers, gallstones, IBS, constipation, Crohn’s disease

4. Digestive System Mouth Pharynx Esophagus Stomach Small Intestine
Large Intestine
Rectum

Nervous System

6. Nervous system
What does it do? Sensory neurons take information from the eyes, ears, nose, tongue, and skin to the brain. Motor neurons carry messages away from the brain and back to the rest of the body.
Common problems/injuries? Brain tumors, cerebral palsy, epilepsy, concussions, meningitis, mental illnesses, migraines

7. Central Nervous System Peripheral Nervous System Nervous System
The Nervous System is divided into 2 parts:
Central
Nervous System
Peripheral
Nervous System

8. Central Nervous System
Cerebrum – 85% of the brain, controls thinking, long and short term memory.
Cerebellum – located at the back of the
brain, controls balance.
Spinal Cord – connects neurons to the brain

9. Peripheral Nervous System
Made up of hugh network of interconnecting neurons across the body.
Cranial Nerve – effects motion and feeling in the face. It does not pass through the spinal cord.

Endocrine System

11. ENDOCRINE system ENDOCRINE = HORMONES
What does it do? The endocrine system helps regulate and maintain various body functions making and releasing hormones.
Common problems/injuries? Diabetes, thyroid disorders
ENDOCRINE = HORMONES

12. Endocrine System Pituitary Gland
“Master Gland”; controls all endocrine glands
Hypothalamus
Controls metabolism and homeostasis
Thyroid Gland
Regulates metabolism
Parathyroid Gland
Controls calcium in blood and bones
Adrenal Gland
Controls metabolism and stress responses
Pinal Gland
Regulates wake/sleep cycle
Reproductive Glands
Controls sex hormones
Pancreas
Aids in food digestion and controls blood sugar levels

Respiratory System

14. Respiratory system
What does it do? To supply the blood with oxygen. We inhale oxygen and exhale carbon dioxide – this gas exchange is how we get the oxygen to the blood
Common problems/injuries? Asthma, bronchitis, emphysema, pneumonia

15. Respiratory System Nasal Cavity is lined with… Cilia Filters the air
Mucous Membranes Moistens the air
Blood Capillaries Warms the air

16. Respiratory System A – Lungs B – Alveoli C – Nasal Cavity D – Mouth
E – Trachea
F – Diaphragm
G – Epiglottis
H – Bronchia
I – Pharynx I G H

Circulatory System

18. Circulatory system
What does it do? It circulates blood through the body. This is our “blood pressure,” which is the contraction and relaxation of our heart muscle.
Systole = Contraction
Diastole = Relaxation
Normal Blood pressure is 120 / 80
Common problems/injuries? Atherosclerosis, high blood pressure, angina, aneurysm, arrythmia

19. Circulatory System atrium ventricle atrium ventricle blue lungs oxygen
The heart is divided into 4 chambers, right ________________ and ____________________ and the left ______________________ and _________________________.
Oxygen poor blood, ____________ blood, circulates to the right side of the heart, it is sent to the _______________ to get __________________. The _______ blood is then sent back to the left side of the heart to be circulated back through the _______________.

Lymphatic System

22. LYMPHATIC = IMMUNE SYSTEM
Lymphatic system
What does it do? The lymphatic system transports fluids throughout the body. The vessels carry proteins to the lymph nodes, which are filled with white blood cells that kill bacteria and other pathogens, before sending the protein back into the body.
Common problems/injuries? Lymphedemia, lymphoma, cancer
LYMPHATIC = IMMUNE SYSTEM
