Bio Body System Test
Reproductive,Immune, Integmentary,Skeletal, Muscular
| Term | Definition |
|---|---|
| Disease | any change that disrupts normal body functions |
| Thymus | Helps with immunity by producing hormones and white blood cells known as T cells |
| Killer T | Type of T cell that track down and destroy pathogens & foreign tissue |
| Helper T | Type of T cells that identify pathogen & send message to Killer T |
| Suppressor T | Type of T cells that turns off the immune response |
| Antibody(AKA good guy) | Produced in response to antigens(bad guy) contains 2 binding sites. Are produced by B cells in the bone marrow. Are very specific to a pathogen. |
| Inflammation | Pathogens enter; blood cells dilate; macrophages destroy them |
| Fever | chemicals are released to kill pathogens that have spread throughout the body. |
| Skin | #1 most important line of defense against pathogens |
| Mouth and Respiratory system | cilia lined cells and mucus that can trap pathogens and swept them into the stomach |
| Infected Animals | by animals or protists |
| Sexual Contact | through bodily fluids |
| Indirect Contact | You used a glue stick after someone with a cold |
| Physical Contact | shaking someone’s hand who has a cold |
| Contaminated Food | eating food that has sat out too long |
| Integumentary System function | 1.Protection against pathogens,UV light, dehydration 2.Regulates body temperature 3. Vitamin Production- when exposed to sunlight the skin produces vitamin D 4.Sensory Info |
| Basal Layer (Epidermis) | Layer that contains protein keratin that waterproofs skin, and the protein melanin that gives you skin color. Contains cell undergoing mitosis. |
| Outer Layer(Epidermis) | Layer that contains cells that flatten out and die |
| Hypodermis | Innermost layer that stores fat |
| Dermis | Middle layer of skin that contains vessels, hair follicles, nail follicles, sensory receptors, and sweat glands. |
| Skeletal System | 1. Support- provides framework that supports the body 2. Red Blood Cell Production 3.Storage of Calcium and Phosphorous 4.Protects many organs from mechanical injury 5. Movement occurs when skeletal muscles attached to bones contract |
| Appendicular | Contains the bones that form the arms and legs; including the bones that attaches them to the main skeletal. |
| Axial | The center bones of the skeleton. |
| Cartilage | Embryo, tip of nose, ears and disc between vertebrae made of this |
| Periosteum | The tough protective layer that surrounds the bone |
| Compact Bone | The outer dense layer of bone |
| Ligaments | Connects one bone to another bone |
| Joints | Place where two bones meet |
| Spongy Bone | Part of bone structure that contains marrow. Red marrow is the location of Red Blood cell production. Yellow Marrow- site of fat storage. Also, provides a lot of strength without more added mass. |
| Origin | Muscle attachment sites that doesn't move |
| Insertion | Bone that is moved by contraction |
| Flexor | muscle that causes a limb to bond at joint |
| Extensor | muscle that causes a limb to straighten at joint. |
| Tendons | Connects muscle to bone |
| Actin | Thin protein filaments |
| Myosin | Thick protein filaments |
| Cardiac Muscle | Type of muscle that is involuntary, striated and only found in the heart. |
| Sketal Muslce | Type of muscle that is voluntary, striated & multi-nucleated. Found attached to bones. |
| Muscle Fibers | An individual muscle cell. The number of fibers that contact at one time is consider your strength, the length of time of the contraction is your endurance. |
| Smooth Muscle | Type of muscles that is involuntary and smooth . Found in the digestive tract. |
| Sarcomeres | Contracting units of a muscle are |
| Scrotum | Sac containing Testes |
| Testes | Produce sperm; secrete hormone testosterone |
| Seminal Vesicles and Prostate Gland | make semen to provide nutrients and protect sperm |
| Bulbourethal Gland | Produces acid neutralizer to protect sperm from urine in the urethea |
| Vas Deferens | Tubes that transport sperm to urethea |
| Ovaries | Produce, release egg cells & production of estrogen |
| Uterus | Site of embryo development |
| Fallopian Tubes | Passageway for egg cell; site of fertilization |
| Vagina | Passageway for sperm to come in; baby to go out |
| Epididymis | located on top of testes where sperm mature and are stored |
