What does the right atrium do? | Takes the deoxygenated blood entering the heart and transfers it to the right ventricle |
What does the right ventricle do? | Pumps deoxygenated blood to the lungs. |
What does the left atrium do? | Oxygenated blood goes from the lungs and enters the left atrium, which then transports down to the left ventricle. |
What does the left ventricle do? | Pumps to the body to give cells oxygen and then travels back to the right atrium. |

What are the 4 chambers in the heart? | Right Atrium, Right Ventricle, Left Atrium, Left Ventricle, |
What do Lymph Nodes do? | Filter foreign substances. |
What does Bone Marrow do? | Produces blood. |
What does the Thymus do? | Trains T-Cells. |
What does the Spleen do? | Filters blood by removing cell waste and getting rid of old/damaged blood cells. |
What do Killer T-Cells do? | Directly attacks and destroys virus-infected cells. |
What do Helper T-Cells do? | Identifies infected cells and such, then notifies killer T-Cells to attack and B-Cells to make antibodies |
What do B-Cells do? | Creates antibodies |
What are all T and B-Cells? | White Blood Cells |
What is Chemical Digestion? | Digestion where you break down or change the chemical composition of food into a new substance. (A Chemical Change) |
What is Mechanical Digestion? | Digestion that only affects the physical form of food, not changing the chemical composition. (A Physical Change) |
What does the Esophagus do? | Move food from mouth to stomach. |
What does the Stomach do? | Digests food with acid and enzymes. |
What does the Liver do? | Filters toxins and makes Bile. |
What does the Gallbladder do? | Stores Bile and uses it to break down fatty foods |
What does the Pancreas do? | Regulates blood sugar with insulin or glucagon. |
What does the Large Intestine do? | Absorb water and vitamins for the body and forms feces and propels it to the rectum for it to be expelled from the body. |
What do the Kidneys do? | Cleanses the bloodstream by separating waste aka urine. |
What is the purpose of the Ureters? | Tubes that urine travels through to the bladder. |
What does the Bladder do? | Stores urine until it is expelled from the body. |
What is the Urethra's Function? | Tube urine travels through to leave the body. |
Epidermis | Strong Protective Covering |
Dermis | Contains Blood Vessels, Sweat Glands, Oil Glands, and Hair Follicles |
Hypodermis(Subcutaneous Fat) | Insulates body, stores fuel, and provides cushion for skin |
Hair Follicles | Protects skin, regulates body temperature, and helps with nerve sensing functions |
Oil Glands | Makes skin waterproof and prevents the skin from dryness |
Sweat Glands | Regulates body temperature and prevents skin from dryness |
Pores | Allows passage of gas and fluid through the surface of the skin |
Blood Vessels | Delivers blood to organs and tissues in the body |
Nerves | Allows you to interact and react to your surroundings |
Skin | Protects from pathogens/bacteria, serves as a protective layer for organs, and regulates body temperature. |
Hypothalamus | Controls the entire endocrine system |
Pituitary | Controls growth/development hormones |
Pineal | Controls melatonin (sleep patterns) |
Thyroid | Controls metabolism (digestion) |
Pancreas | Controls blood sugar (insulin and glucagon) |
Adrenal | Produces adrenaline (fight or flight) |
Central Nervous System | Brain and Spine |
Spinal Cord | Allows your brain to communicate with the rest of the body |
Brain | Receives impulses from the body (nerves) |
Peripheral Nervous System | The nerves |
