Fixed joint? |
No movement when you are adult (skull) |
|
|
Gliding joint? |
Allows for bones to slide (wrist) |
|
|
How do muscles work? |
They work against each other (biceps against triceps) so when one is contracted, the other relaxed |
|
|
Arm moving upwards? |
Biceps contract and triceps relax |
|
|
Arm moving downwards |
Biceps relax and triceps contract |
|
|

Quadriceps (quads) |
|
|
Triceps of upper legs? |
Hamstrings (hams) |
|
|
Biceps of lower leg? |
Tibialis anterior (TA) |
|
|
Triceps of lower leg? |
Gastrocnemius (gastro) |
|
|
Joints are made of? |
Ligament Cartilage Synovial membrane and fluid |
|
|
Cartilage function? |
Shock absorber for bones |
|
|
Synovial fluid function? |
Lubricates bone |
|
|
Synovial membrane function |
Protects synovial fluid |
|
|
Ligament function? |
Joins 2 bones in a joint |
|
|
Red blood cells function? |
Carries oxygen around the body in exchange of carbon dioxide |
|
|
White blood cell function? |
Fights infection |
|
|
Platelet function? |
Helps with blood clots
(Remember cells at work!) |
|
|
What is a hormone? |
Chemical messengers to your cells |
|
|
Artery function? |
Take oxygenated blood away from heart Thick walls and narrow hole Appears red |
|
|
Vein function? |
Takes de-oxygenated blood back to heart Thin walls and large hole Appears blue Has valves |
|
|
Capillary function? |
Carries nutrients and hormones through tissues One cell thick |
|
|
Circulatory order? |
Vena cava -> right atrium -> right ventricle -> pulmonary artery -> lungs -> pulmonary vein -> left atrium -> left ventricle -> aorta (biggest artery) |
|
|
Where is blood produced? |
Bone marrow |
|
|
Respiration meaning? |
Converting oxygen into energy and carbon dioxide |
|
|
Aerobic vs anaerobic? |
Aerobic is with oxygen and anaerobic is without (can cause cramps from acid) |
|
|
Aerobic formula? |
Oxygen + glucose = c02 + h20 + atp(energy) |
|
|
Anaerobic formula? |
Glucose = lactific acid and ATP |
|
|
Breathing vs respiration? |
Breathing is inhaling gases Respiration is transforming oxygen from gas into energy |
|
|
Order of oxygen into lungs? |
Nasal cavity (mouth nose) -> trachea -> pharynx -> larynx -> trachea -> branchi -> bronicholes -> alveoli -> blood |
|
|
Inhalation process? |
Intercostal muscles expand making rib cage bigger Diaphragm contracts and moved downwards increasing lung capacity
Diaphragm turns flat |
|
|
Exhalation process? |
Intercostal muscles relax making rib cage smaller Diaphragm expands and moves upwards shrinking the lung capacity
Diaphragm turns curved |
|
|
