um science- CIRCULATION,RESPIRATION,DEFENSE (eww) Flashcards
um study obviously
blood flows in
atrium
blood goes out
ventricle
tiny vessels that carry materials to your cells
capillary
carry blood AWAY from the heart
artery
carry blood TO the heart
vein
pieces of protein helps form cots
platelet
organisms that cause disease
pathogen
a disease caused by a pathogen
infectious disease
resistant to a particular infection
immune
a dose of a pathogen or antigen that “tricks” your immune system into making antibodies and memory cells
vaccine
white blood cells that swallow and destroy microorganisms and debris in the blood
phagocyte
recognizes a pathogen
lymphocyte
a protein on the surface of a lymphocyte
antibody
large, sheet-like muscle below the lungs
diaphragm
grape-like clusters surrounded by networks of thin walled pulmonary capillaries
aveoli
describe where a red blood cell goes
Right atrium-Right ventricle-Pulmonary artery-Lungs(pick oxygen)-Pulmonary vein-Left atrium-Left ventricle-Aorta
5 functions of CIRCULATORY system
- transport nutrient to our cells
- transport oxygen to our cells
- move wastes products out of our body
- transport white blood cells to where needed
- keep our extremities warm
4 major groups of pathogens and give example of each
bacteria; food poisoning
viruses; common cold
fungi; ringworm, athlete’s foot
protozoa; maleria
2 hereditary diseases
type 1 diabetes
hemophilia
2 diseases that can be caused by the enviorment
cancer
obesity
4 parts of our bodies first line of defense against pathogens
- skin and sweat
- saliva and tears
- mucous membranes in our nose and throat
- stomach acid
how is aids different than any other known pathogenic disease
the virus attacks our T cells which prevents our immune system from doing its job
how can the miss-use of antibiotics make them less effective
underuse; not killing all of the bacteria
overuse; using when not needed
contributions of robert koch
proved pathogens cause disease (rat experiment)
contributions of louis pasteur
knew there was microscopic ‘‘things’’ around us
contributions of edward jenner
first vaccine _ smallpox
3 respiratory diseases and their cause
- asthma; air pollution
- lung cancer; smoking
- pneumonia; infection of the aveoli (by bacteria)
