e. Right ventricle pumps blood to lungs to get __________________
and give off ________________________________
f. Left ventricle pumps oxygen rich blood to the rest of your body where
the cells take the oxygen from the blood and give carbon dioxide
g. Blood flows back to the atrium on the __________________ side of
your heart
3. Blood Vessels
a. _____________________ – carry blood __________ from your heart
i. thick, flexible muscle walls to stand pressure of blood being
pumped out of the heart
b. ____________________ – carry blood ________________ your heart
i. thinner walls than arteries because the pressure of blood is
lower in veins
ii. they have small flaps in veins keep blood flowing in 1 direction
c. ____________________ – thin blood vessels that connect arteries to
veins
i. very thin walls
ii. every tissue has these next to it
iii. nutrients, oxygen, and wastes pass in and out through capillary
walls
iv. plasma also passes through walls
d. _____________________ – excess plasma, plus tissue fluid that
surrounds body cells, colorless (blister)
i. carries cell wastes and other materials
ii. lymph tissue also produces a kind of white blood cell

3. What are the chambers of the heart called?
Vocabulary – Lesson 6 – Respiratory System
1. trachea –
2. bronchial tubes –
3. alveoli –
4. inhalation –
5. exhalation –
6. breathing –
7. diaphragm –
Notes – Lesson 6
1. Organs that help you breath make up the respiratory system – draws air into
your lungs, takes _____________ from the air for your body to use, helps
remove ________________________________
2. How does air travel to your lungs
a. Air comes into your body through your nose and mouth
b. It then enters your throat (pharynx) to your voice box (larynx)
c. From this point it moves through a pipe called the trachea, or
______________________
d. The trachea is divided at the end into 2 branches called bronchial
tubes or bronchi
e. Air moves into your lungs through these tubes, which branch into
smaller tubes (_______________________), which lead to tiny air
sacs called _______________________
f. In the lungs (sponge like)
i. Air you breathe in fills up the alveoli
ii. Oxygen passes from the ________________ into the
____________________
iii. RBC in the capillaries pick up the oxygen
iv. Your blood takes the oxygen to the rest of your cells
g. Deoxygenated blood
i. Blood delivers _________________ and picks up
___________________________ given off by your cells
ii. Carbon dioxide moves through the body to the capillaries in the
alveoli and into the lungs
iii. It then leaves the body when you breathe out
3. The breathing process
a. ________________________ – moving air in and out of the lungs
b. Breathing involves both ________________ and ________________
c. _________________ – is the process in which the air enters the lungs
d. _________________ – is the process in which the air leaves the lungs
e. Inhalation occurs when the diaphragm contracts and the rib cage
expands
f. _________________– is a muscle that separates the chest from the
abdomen, helps to also force air out of the lungs
4. How does your body clean the air you breathe?
a. Hairs in your nose being the cleaning by screening out some particles
b. Sticky ____________________ traps more
i. this lines your nasal passages and the walls of your trachea and
bronchial tubes
ii. it may trap germs and other harmful matter
c. Trachea and bronchial tubes have tiny hairs called _______________
i. Cilia wave quickly back and forth and push mucus that has
trapped dirt and dust up toward your __________________
d. When you swallow, much of the mucus passes into the
_____________________________________
