makes up two thirds of your palate, provides structure in the mouth, and allows space for the tongue to move around.
completely separates the mouth from the throat, keeping food out of the respiratory tract.
makes saliva which helps with chewing and swallowing
serves as a passageway for both air and food
move food to stomach by rhythmic waves of muscular contractions
temporary storage for food, mixing and breakdown of food, and digestion of food.
gateway between the stomach and small intestine
separates the esophagus from the stomach and prevents the backward flow of blood.
breaks down food from the stomach and absorbs nutrients from the food.
first part of the small intestine and key part of the breaking-down process
attaches parts of the intestine to the interior abdominal wall
protect good bacteria in the gut
Absorbs water and forms feces
stores the remains of digested food that will be emptied into the rectum
connects colon to anus and is it receives stool from
terminal end or opening of the digestive tract to the outside of the body
regulates chemical levels and excretes a product called bile
makes enzymes and insulin
house of the digestive system
housing to lungs and heart
throat; passageway for food to the esophagus and air to the larynx
a flap of cartilage that covers the windpipe while swallowing
Allows air to pass to and from lungs
carries air in through to the functional tissues of the lungs called alveoli
Airways in the lungs that lead from the bronchi to the alveoli.
organs of the respiratory system that bring oxygen-rich air into the body and send oxygen-poor air out of the body
tiny sacs in lungs which gas exchange occurs
Large, flat muscle at the bottom of the chest cavity that helps with breathing
makes white blood cells and anti bodies
produces hormones that regulate metabolism, body heat, and bone growth
A pair of endocrine glands that sit just above the kidneys and secrete hormones that help arouse the body in times of stress.
Glands that produce the egg cells and hormones
A hollow, muscular organ that pumps blood throughout the body.
Double-layered membrane surrounding the heart.
the two upper chambers of the heart
Lower chambers of the heart
supply oxygen-rich blood to the myocardium and go across the heart
superior vena cava
receives blood from the head and arms and chest and empties into the right atrium of the heart
inferior vena cava
carries blood from lower regions of the body to right atrium
carrying blood from the right ventricle of the heart to the lungs for oxygenation.
carry the oxygenated blood from the lungs into the left atrium of the heart
The large arterial trunk that carries blood from the heart to be distributed by branch arteries through the body.
blood vessel that carries blood to the kidney
blood vessel that carries blood away from the kidney and toward the heart
Organ near the stomach that produces, stores, and eliminates blood cells and filters blood
Filters waste from the blood like urea, water, salt and proteins.
tube that carries urine from the kidney to the urinary bladder
outer layer of the kidney, home of nephrons
medulla and pyramids
the inner region of the kidney is the ____, and it is made up of cone-shaped masses of tissue called ____
funnel-shaped reservoir that collects the urine and passes it to the ureter
Functional units of the kidneys
Area of the brain responsible for all voluntary activities of the body
separates the two cerebral hemispheres
three protective membranes that surround the brain and spinal cord
a broad band of nerve fibers joining the two hemispheres of the brain.
Connection to spinal cord. Filters information flow between peripheral nervous system and the rest of the brain.
Nerves that run up and down the length of the back and transmit most messages between the body and brain
Part of the brainstem that controls vital life-sustaining functions such as heartbeat, breathing, blood pressure, and digestion.
A brain structure that relays information from the cerebellum to the rest of the brain
A small part of the brain above the pons that integrates sensory information and relays it upward.
the nerve that carries neural impulses from the eye to the brain
the brain's sensory switchboard, located on top of the brainstem; it directs messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum and medulla
a neural structure lying below the thalamus; directs eating, drinking, body temperature; helps govern the endocrine system via the pituitary gland, and is linked to emotion
The endocrine system's most influential gland. Under the influence of the hypothalamus, regulates growth and controls other endocrine glands.
white of the eye
The clear tissue that covers the front of the eye
a ring of muscle tissue that forms the colored portion of the eye around the pupil and controls the size of the pupil opening
lens of eye
The main optical function of the lens is to transmit light, focusing it on the retina. The cornea contributes about 80% of total refraction, while the lens fine-tunes the focusing of light onto the retina.
soft, jelly-like material behind the lens in the viterious chamber, helps maintain shape of eyeball
Light sensitive layer of the eye; contains rods and cones
A reflective layer of the choroid in the eyes of many animals, causing them to shine in the dark.
Divides the right and left chambers of the heart
functions as a one-way valve that closes during ventricular systole to prevent regurgitation of blood from the right ventricle back into the right atrium. It opens during ventricular diastole, allowing blood to flow from the right atrium into the right ventricle.
Located on the left side of the heart between the left atrium and left ventricle
A large structure of the hindbrain that controls fine motor skills.
