What is the name of the group of heart cells that
sends out signals that make the heart muscle
contract? (its located in the right atrium)
3100
pacemaker
4200
How do the heart and veins keep blood from
flowing backwards?
5200
They use valves to allow blood to pass through
and then close to keep it from moving backwards.
6300
What are the 3 main functions of the
cardiovascular system?
7300
- Delivering needed materials
- Removing waste products
- Fighting disease
8400
Which ventricle exerts more force when pumping?
Why?
9400
Left ventricle. The left ventricle pumps blood
to the entire body, while the right ventricle
pumps blood only to the lungs.
10500
Explain the movement of blood in our two loop
system.
11500
In the first loop, oxygen-poor blood travels from
the heart to the lungs and then back to the
heart. In the second loop, oxygen-rich blood is
pumped from the heart throughout the body and
then returns again to the heart.
12100
Blood is made up of what 4 components?
13100
- Plasma
- Red blood cells
- White blood cells
- Platelets
14200
Whats the purpose of the lymphatic system?
15200
It is a network of vein-like vessels that return
fluids to the bloodstream like a gutter during
a rain storm.
16300
Where do you find hemoglobin? What is its
function?
17300
Hemoglobin makes up most of the red blood cell.
It binds chemically to oxygen molecules so that
the red blood cell can pick up and release oxygen
throughout the body.
18400
- Name the function of each
- Red blood cell
- White blood cell
- Platelet
19400
- Carry oxygen to the bodys cells
- Fight disease
- Release chemicals to start process of blood
clotting.
20500
Explain the idea of a universal
recipient? Explain the idea of a universal
donor?
21500
Universal recipients are AB because AB blood
does not contain clumping proteins. Universal
donors are O- because O- blood cells do not have
anti-A or anti-B markers.
22100
What are the 3 important things you should do to
avoid such cardiovascular health problems such a
heart attack or hypertension?
23100
- Exercise regularly
- Eat balanced diet (low sat. fat, trans fat,
cholesterol, sodium) - Dont smoke.
24200
Capillaries have very thin walls. What process
occurs often in capillaries where molecules move
from an area of higher concentration to an area
of lower concentration?
25200
diffusion
26300
What is the name of the condition where an artery
wall thickens as a result of the buildup of fatty
materials?
27300
atherosclerosis
28400
How many layers does an artery wall have? What
is each layer called?
29400
- Three.
- Epithelial cells
- Smooth muscle
- Connective tissue
30500
Since the pushing force of the heart is minimal
for veins (when compared to arteries), what are
the three factors that help move blood through
veins?
31500
- Contraction of skeletal muscles.
- Larger veins have valves to prevent backward
flow. - Breathing exerts pressure against veins in the
chest.
32100
What stretches across your larynx? What is its
purpose?
33100
2 vocal cords Its purpose is to produce sound
when they contract and air rushes past them.
34200
Explain the difference between breathing and
respiration.
35200
Breathing is the movement of air into and out of
the lungs. Respiration is the when oxygen and
glucose undergo a complex series of chemical
reactions in side cells to release energy for the
body.
36300
What are cilia? What do they do?
37300
Cilia are tiny hair-like extensions found in the
nasal cavities that move together in a sweeping
motion. They sweep the mucus into the throat and
then stomach. There, stomach acid destroys the
mucus and material trapped in it.

Whats the difference between the bronchi and
alveoli? What do each do?
41500
Bronchi are the passages that direct air into the
lungs. Alveoli are tiny sacs of lung tissue at
the end of the bronchi branches that facilitate
gas exchange oxygen ?? carbon dioxide and water
42100
What type of waste is the excretory system
removing from the body?
43100
cellular waste
44200
How does urine get from the kidneys to the
bladder?
45200
Through two small tubes called ureters.
46300
Whats the difference between urea and urine?
47300
Urea is the chemical that comes from the
breakdown of proteins. Urine is the watery fluid
that contains urea and other wastes after leaving
the kidneys.
48400
Explain how homeostasis and excretion are related.
49400
Homeostasis keeps the bodys internal environment
stable. The excretory system must balance how
much of the materials to either filter out or
reabsorb depending on the factors acting upon the
body. Homeostasis helps keep this balance.
50500
Explain the filtration process done by millions
of nephrons in the kidney. Be specific on what
materials are involved in filtration and
absorption.
51500
- Blood flows from artery into kidney.
- Blood gets filtered in cluster of capillaries.
Urea, water, glucose and other materials get
passed into surrounding capsule. - Materials removed pass into long, twisting tubule
surrounded by capillaries. - Most of water and glucose gets reabsorbed, while
urea does not. - After reabsorption process, fluid leaves kidney
and is called urine.
