systems Flashcards
(19 cards)
musculoskeletal
made up of bones/muscles, supports/protects organs, makes movement possible
connective tissue that make up skeleton (3)
bones ligaments cartilage
nervous system
bodys control system, brain spinal cord nerves
3 groups of nerves in nervous system
- nerves that control voluntary muscles
- nerves that carry info from SENSE ory organs
- nerves that regulate involuntary functions
whats the function or sensory receptors
special cells/tissue that receive input from environment (eyes sensitive to light, skin sensitive to temps)
lymphatic system
vessels that collect fluid from body & returns to blood, fights off infection
endocrine system
glands produce hormones, regulates growth, reproduction, energy production
excretory system
kidney, bladder, filters blood and eliminates waste
reproductive system
male/female parts produce sperm/egg, create offspring
respiratory system
gas exchange, exchange O2 for CO2, tubes leading to lungs
digestive system
-group of organs break down food/absorb nutrients for fuel, eliminates waste
whats the path food takes in digestive system
mouth (breaks down food/enzymes in saliva and teeth) , esophagus, stomach (phys/chem digestion,break down into proteins) , small intestine (absorb nutrients into blood), large intestine (absorbs water/minerals) , rectum anus (temp storage and elimination of waste)
3 accessory organs (digestion)
salivary glands liver pancreas
circulatory system
- heart/blood vessels carry blood/subs around body
- supplies nutrients and eliminates waste from cells
- blood heart blood vessels
4 components of blood
red blood cells
white blood cells
platelets
plasma
3 tissues present in heart
- cardiac muscle
- nerve
- connective
3 blood vessels in circulatory system
- arteries (carry blood from heart)
- capillaries (blood vessels w thin walls allowing diffusion)
- veins (carry blood to heart)
how digestive and circulatory work together
digestive gets nutrients from food hands over to blood, circulatory carries them where they gotta go, filters waste
how respiratory and circulatory systems work together
circulate blood/o2 through body, air moves in/out of lungs, blood moves in/out of lungs to heart
