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

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

Nervous SystemThe Nervous System is divided into 2 parts:

Central Nervous Central Nervous SystemSystem

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

Peripheral Peripheral Nervous Nervous SystemSystemMade 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.

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

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

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

Nasal Cavity is lined with…

Cilia Filters the air

Mucous Membranes Moistens the air

Blood Capillaries Warms the air

I A – Lungs

B – Alveoli

C – Nasal Cavity

D – Mouth

E – Trachea

F – Diaphragm

G – Epiglottis

H – Bronchia

I – Pharynx

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

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 _______________.

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

We have lymph nodes

all throughout our body,

what is the largest one?
