Body Systems
red blood cells
transports nutrients, gas, and waste to the body; gives blood it's color
Bronchi
two short branches located at the lower end of the trachea that carry air into the lungs
muscular system
works with the skeletal system to allow the body to move
right atrium and right ventricle
contain oxygen-poor blood
left atrium and left ventricle
contain oxygen-rich blood
skeletal system
gives the body structure and protects internal organs
circulatory system parts
heart, arteries, capillaries, veins, blood, white blood cells
immune system
helps fight viruses, germs, and diseases
diaphragm
large, flat muscle at the bottom of the chest cavity that helps with breathing; when it is contracted oxygen is inhaled, and when it is relaxed carbon dioxide is exhaled
digestive system parts
mouth, esophagus, stomach, liver, pancreas, small intestine, large intestine, rectum, anus
respiratory system parts
nose, trachea, larynx, bronchi, lungs, alveoli, diaphragm
white blood cells
part of the blood that helps destroy bacteria and fight disease
platelets
part of the blood that helps it clot to form scabs
reproductive system
produces sex cells that can unite with other sex cells to create offspring
integumentary system
protects the body, releases excess water in sweat, and helps regulate body temperature
excretory system
removes waste products from the body
nervous system
responds to stimuli in the environment, and controls most body functions
sequence of blood flow
right atrium, right ventricle, lungs, left atrium, left ventricle, aorta
Alvioli
small air sacs in the lungs where oxygen and carbon dioxide are exchanged
capillary
smallest blood vessel; brings nutrients and oxygen to the tissues and absorbs carbon dioxide and waste products
Bronchioles
smallest branches of the bronchi
digestive system
breaks down food to give the body energy
respiratory system
takes oxygen into the body when we inhale, and releases carbon dioxide when we exhale
circulatory system
carries needed materials to the body cells, including oxygen; carries waste away from the body, including carbon dioxide
veins
carry oxygen-poor blood back to the heart
plasma
Liquid part of blood, made mostly of water, salt, sugar, and protein
arteries
carry oxygen-rich blood away from the heart to other parts of the body
