| Question | Answer |
|---|---|
| respiratory | brings oxygen, removes carbon dioxide |
| Cardiovascular (circulatory) | transport blood, oxygen, carbon dioxide, nutrients and waste |
| Nervous | sends electrical messages, senses stimuli, coordinates rapid responses |
| Muscular | contracts to produce movement |
| Skeletal | supports/protects organs: attachment points for muscles |
| excretory | organs like kidneys remove waste from blood |
| digestive | breaks down food and absorbs nutrients |
| bone marrow/hematopoiesis | produces red & white blood cells |
| Respiratory/ cardiovascular (interaction) | cardiovascular- lungs exchange gases, blood carries and oxygen to tissue and carbon dioxide to lungs for exhalation |
| cardiovascular/ digestive (interaction) | absorbed nutrients enter bloodstream (digestive) distributes to cells (cardiovascular) |
| nervous/muscular (interaction) | sensory neurons go to the spinal cord/brain go to motor neurons go to muscle movement |
| excretory/respiratory (interaction) | kidneys remove chemical wastes, lungs remove gas waste (carbon dioxide) |
| skeletal/muscular (interaction) | bones provide leverage and attachment for movement |
| inhalation | air with oxygen goes to alveoli goes to oxygen diffuses into capillaries |
| exhalation | carbon dioxide from blood to the alveoli to out of body |
| arteries vs. veins | arteries generally carry oxygenated blood away from heart: veins generally carry deoxygenated blood to heart (pulmonary exceptions exist |
| how do respiratory and cardiovascular system support survivial? | oxygen inhaled and diffuses into blood and then carried into tissues, carbon dioxide from celles is carried back to lungs and exhaled |
| why can a broken forearm stop movement | bones support muscles: a fracture disrupts structure so muscles cannot move the limb normally |
| what happens in a reflex when you touch a hot pot | signal sent to spinal cord, motor neurons trigger muscle to withdraw hand |
| which system brings in oxygen? | respiratory |
| which system sends electrical messages? | nervous |
| name 2 systems that remove waste from blood | excretory (kidneys) and respiratory (lungs) |
| where are red blood cells made | bone marrow |
| which system makes white blood cells inside the bones | immune |
