the maintenance of a stable internal environment that all the human organ systems work together to achieve

organ system, regulates body processes through hormone production

organ system, gas exchange between the internal and external environment

organ system, physical and chemical breakdown of food to aloow absorption of nutrients

organ system, production of reproductive cells that will generate offspring

organ system, protection against the external environment and regulation of temperature

organ system, does voluntary and involuntary movement, enables movement

organ system, processing center for sensory input, using the input to elicit appropriate responses

organ system, circulation of blood, which transports gases, nutrients, hormones, and wastes

organ system, circulation of lymph, which maintains fluid balance and helps fight infection

organ system, filtration of blood and excretion of wastes from the body

organ system, support and protection of many internal organs

this attaches bones together

this attached skeletal muscles to bones

is a bone where marrow is. blood cells are made in the marrow of this bone.

these muscles are involuntary

this muscle is voluntary

muscle usually attached to the skeleton

muscle found in the walls of the heart

muscles found in walls of internal organs and blood vessels

the major organ/muscle of the cardiovascular system

organ pumps blood through four chambers

the bottom chambers of the heart

the top chambers of the heart

circulation where blood is pumped to the lungs and back, getting oxygenated in the process

circulation where blood is pumped to the whole body starting in the aorta and then come back to the heart

one way door like structures that regulate the flow of blood between the chambers of the heart

prevents the backwards flow of blood

blood vessels that carry clood away from the heart, to the organs of the body

blood vessels that carry blood back to the heart and away from the body's organs

small blood vessels where gas exchange occurs

the fluid that circulates in the heart and blood vessels to carry oxygen to organs

cells that contain hemoglobin

an iron rich protein that carries oxygen, found in red blood cells

function in the immune system, helps fight against foreign particles

help in blood clotting

fluid of the blood made mostly of water

organ that helps to filter toxins in the blood

the four main blood types

organ chews and grinds food

organ where saliva begins chemical breakdown of food

pipe connecting mouth to the stomach

organ secretes an extraordinarily strong acid (ph=2) that leads to the breakdown of food

substance formed when food is broken down in the stomach and mixed with digestive juices

organ that produces the hormone insulin that regulates blood sugar levels

organ that helps neutralie stomach acid

organ that PRODUCES bile, which breaks down fats in food

pouch-like organ that STORES bile for future use

chyme enters this organ after digestion is complete where it is absorbed into the bloodstream

this is what chyme is propelled by. these are folded surfaces located in the small intestine

removes water from the chyme and gets the waste ready from excretion

internal entry and exit point for air

serves as a passage way for both air and food at the back of the throat

your "voicebox"

your "windpipe"

you speak because of this organ when air passes over the vocal chords

connects the pharynx to the lungs

a piece of skin that covers the trachea. when you swallow, preventing food from entering

two large passage ways that lead from the trachea to the lungs

what bronchi are subdivided into

what bronchioles subdivide into

organ that are in clusters, like grapes

capillaries are where the gas exchange occurs and surround each one of this orga

the muscle that causes you to breathe

hiccups are involuntary contractions of this organ

main organ of the excretory system

waste-laden blood enters this organ and the organ filters out urea, excess water, and other waste products, which eventually travel out of the organ as urine

organ that transports urine from kidneys to urinary bladder

solid (food) waste travels out of the body through this organ

sweat glands remove excess water and salts from the body in this organ

expels the waste gas called carbon dioxide (CO2)

control center of the body

controls thought and senses. in the brain

controls motor functions

organ that sends instructions from the brain to the rest of the body, and vice versa

any organism with a major nerve cord is classified as this

organ conducts impulses to muscle cells throughout the body

what the endocrine system produces and secretes

the first line of defense against foreign particles

cells that recognize disease agents (antigens) and create antibodies to tag and remove these antigens

the type of WBC that eats and destroys antigens

organ that helps restore fluid lost from the blood and return it to the cardiovascular system

the male reproductive cell

organ produces sperm and the hormone testosterone

organ that transfers sperm to a female and carries urine out of the body

tube that transfers sperm to penis

produces the female egg cells necessary for reproduction

transport the egg cell to the site of fertilization, where it gets fertilized by sperm.

where the fertlized egg is implanted into the walls of, beginning the initial stages of pregnancy

outermost layer of skin

layer of skin below epidermis

layer of skin responsible for sensory details (touch)

type of joint this is (cranium)

type of joint this is (wrist)

type of joint this is (knee)

type of joint this is (neck)

type of joint this is (shoulder)

carries oxygen-rich blood from the left ventricle of the heart to the body

a large vein that carries oxygen-poor blood to the right atrium from the lower half of the body

heart chamber that recieves oxygen-rich blood ffrom the lungs via the pulmonary vein.

biggest and longest artery in the body

left upper chamber of the heart

the left lower chamber of the heart

heart chamber that pumps blood through the aortic valve into the aorta

the valve between the left atrium and ventricle

valve that prevents the back flow of blood from the left ventricle to the left atrium

the blood vessel that carries oxygen-poor blood from the right ventricle to the lungs

the blood vessel that acrries oxygen-rich blood from the lungs to the left atrium

the right upper chamber of the heart

chamber ofheart that recieves oxygen-poor blood from the body through the inferior and superior vena cavas

chamber of heart that pumps blood into the pulmonary artery

the muscular wall that speperats the left and right sides of the heart

the right lower chamber of the heart

a large vein that carries oxygen-poor blood to the right atrium from the upper parts of the body
