- - - - Spinal Cord- complex organization of nerve cells responsible for movement and sensation, carries signals between brain and the rest of the body
        
        Nerves- cord-like structures, role is to provide pathways to conduct electrical impulses throughout the body. It relays information from one part of the body to another
        
        Neurons- fundamental units of brain and nervous system, the cells responsible for receiving sensory input from external world, sends motor commands to muscles, and for transforming and relaying the electrical signals
- - - - Pituitary Gland- Secrete hormones into your bloodstream
        
        Parathyroid Gland- produce parathyroid hormone (PTH) which regulates serum calcium and phosphorus concentrations
        
        Thyroid Gland-Thyroxine (T4) level determines the body's metabolic rate
        
        Adrenal Gland- releases epinephrine (adrenaline) and norepinephrine, both increase heart output, blood pressure, and blood glucose, and slow digestion
        
        Pancreas-affects blood concentrations of the hormone insulin
- - - - Ureters- Takes the urine to the bladder
        
        Bladder- stores urine, allowing urination to be infrequent and controlled
        
        Urethra- tube that carries urine from the bladder to outside of the body
- - - - Right Ventricle- responsible for pumping oxygen-depleted blood to the lungs
        
        Left Atrium-collects blood from the pulmonary veins and ejects it into the left ventricle
        
        Left Ventricle- pumps the oxygen-rich blood to the body through a large network of arteries
        
        Pulmonary Artery- Blood flow to the lungs
        
        Veins-return deoxygenated blood back to your heart
        
        Aorta- pumps oxygenated blood to the body

- - - - Trachea-main passageway
        
        Bronchi- two bronchi, the bronchi branch out repeatedly, becoming bronchioles
        
        Lungs- process of gas exchange
        
        Alveoli- are small sacks that have very thin walls, allowing oxygen to easily move through them into the blood and carbon dioxide to move from the blood to the air
        
        Capillaries- take the oxygen away and deliver carbon dioxide
