Respiratory system key structures and organs - CORRECT ANSWERS · consists of lungs,
passageways for air flow, blood vessels, and muscles.
· They work together to bring oxygen into the body and expel carbon dioxide, that is produced
during metabolism.
· Lungs-primary organ- which exchange gases (oxygen and carbon dioxide) during breathing.
upper respiratory tract - CORRECT ANSWERS nose, pharynx (throat), and larynx (voice box)
lower respiratory tract - CORRECT ANSWERS · trachea, (windpipe), bronchial tree, and lungs
Respiration - CORRECT ANSWERS events that deliver oxygen into the body followed by the
transfer of carbon dioxide out of the body. This occurs in tiny air sacks called alveoli.
Respiratory Process - CORRECT ANSWERS oxygen is delivered from the air through the
respiratory passages into the air sacks in the lungs. Oxygen move int the blood in the capillaries.
Carbon dioxide moves from blood to air sacks through respiratory passages and is expelled
through mouth or nose.
cardiovascular system - CORRECT ANSWERS consists of heart and blood vessels; The heart is a
pump that has four chambers: two upper chambers and two lower chambers; Two categories
of blood vessels- arteries and veins; Arteries- carry blood away from the heart to the body
tissues; Veins-carry oxygen-poor blood back to the heart; ARTERY BLOOD VESSELS- muscles on
left of heart pump take blood out of the heart through the AORTA (largest artery)
circulation - CORRECT ANSWERS provides supply of nutrients and oxygen to the body's cells
through the flow of blood.

absorption, and elimination

digestive system organs - CORRECT ANSWERS Mouth-food broken down by teeth and saliva
Esophagus- tube 9-10 inches long connected to stomach
Stomach-helps digest food, by mixing it with digestive juices and churning it into a thin liquid
Small intestine- absorbs nutrients into the bloodstream
Large Intestine-Undigested food and fluids that exit small intestine, creates stool
Anus- stool is eliminated after it passes from large intestine into the rectum
Accessory organs-salivary glands, liver, gallbladder, and pancreas
urinary system function - CORRECT ANSWERS Balance's fluids in body by stimulating thirst and
producing, storing, and eliminating urine.
urinary system organs - CORRECT ANSWERS 1) Kidney- filters waste products (urea, uric, acid)
from bloodstream and removes the products in form of urine so that they don't become
wasteful to body. It also reabsorbs fluids and other substances back to the bloodstream, so
body doesn't lose too much water and essential salts.
2) Ureter-connected to kidneys, urine flows out of kidney through ureter
3) Bladder-holding reservoir for urine
4) Urethra- when urine start to flow it travels through it and expelled from body. Female (1-2
in) Male (8 in.)
immune system - CORRECT ANSWERS (lymphatic system) is a complex network of cells,
tissues, and organs that work together to defend and protect the body against foreign invaders
that can cause sickness and disease.
white blood cells (leukocytes) - CORRECT ANSWERS it's job is to find and destroy bacteria,
viruses, parasites, fungi, and substances that appear foreign and harmful.

integumentary system functions - CORRECT ANSWERS 1) Protects from environment-deeper
tissue from loss of water, salts, heat, and prevents bacteria from entering body
2) Encloses-cover and protects fibers that send messages of pain, temperature, pressure, and
touch to brain
3) Lubrication-Two types of glands that produce sebum and sweat. Sebum-oily.
endocrine system - CORRECT ANSWERS Sends chemical messages (signals) called hormones
reproductive system - CORRECT ANSWERS produce, nourish, and transport either egg or
sperm.
top ten deadliest diseases - CORRECT ANSWERS Coronary artery diseases, stroke, lower
respiratory infections like the flu, chronic obstructive pulmonary diseases, respiratory cancers,
diabetes mellitus, Alzheimer disease and other dementias, diarrheal diseases that result in
dehydration, tuberculosis, and cirrhosis.
four main types of germs - CORRECT ANSWERS Bacteria, viruses, fungi, parasites
Transmitted by: Direct contact, Indirect contact, bites, and contamination.
Common cold symptoms - CORRECT ANSWERS watery eyes, nasal and chest congestion,
sneezing, sore or scratchy throat
Flu symptoms - CORRECT ANSWERS fatigue, muscle stiffness, coughs, sore throat, and nasal
congestion, headaches, high fever
Mononucleosis(mono) symptoms - CORRECT ANSWERS fatigue, swollen lymph nodes in neck
and armpits, swollen tonsils, sore throat, soft swollen spleen fever, headache, skin rash
