Definition
Trachea
Term
What are the 2 tubes that lead to lungs?
Definition
Bronchi
Term
Describe the bronchioles.
Definition
small branches in lungs, lined with ciliated cells that secrete mucus to entrap foreign particles and carry them upward to be swallowed.
Term
T/F. The muscle that controls breathing is the diaphragm.
Definition
True
Term

When you inhale, the diaphragm (lowers/raises), and the surface area (increases/decreases).

 

Only 2 answers are right, choose one out of each pair.

Definition
 lowers, increases
Term
When you ______, diaphragm raises and the surface area (increases/decreases).
Definition

exhale

decreases

Term
What do the alveoli do?
Definition
increase lung surface area for diffusion
Term
Alveoli are surrounded by _________ that keep a constant flow of blood over them.
Definition
capillaries
Term
T/F. Humans swallow approximately 1 gallon of mucus a day.
Definition
False, 1 quart.
Term
The alveoli are also surrounded by capillaries to aid in ___ exchange.
Definition
gas
Term
How many alveoli does each lung contain? What's the approximate surface area?
Definition

1.300 million

2.40X greater than the skin

Term
of the __ that diffuses into the blood, 97% goes into the ___ blood cell where it combines with __________ that has 4 ____ atoms that can combine with each __.
Definition

1.O2

2.red

3.hemoglobin

4.iron

5.O2

Term
Why does O2 diffuse into the cells/tissues?
Definition
because the oxygen level is higher in the blood than in the cell
Term
Why is there a high level of carbon dioxide in cells and tissues?
Definition
because it's the biproduct of cellular respiration which diffuses into the blood later on.
Term
The circulatory system consists of the ____ and _____ _______.
Definition
heart and blood vessels
Term
What is the job of the circulatory system?
Definition
to deliver nutrients and oxygen to tissue, cells, and to remove waste
Term
The heart has a __________ which is a sac like membrane that secretes fluid and reduces friction as heart pumps.
Definition
pericardium
Term
List and describe the layers of the heart.(3)
Definition

Epicardium(outside)-often filled w/ fat

Myocardium(middle)-cardiac muscle tissue, connective tissue, fibrous tissue[strength]

Endocardium-lines heart chamber, makes most of tissue of heart valves

Term
What are the 2 types of blood circulation?
Definition
Pulmonary and Systemic
Term
What's the difference between the 2 types of blood circulation?
Definition

Pulmonary carries blood from heart to lungs back to heart

 

Systemic carries blood from heart to body cells back to heart

Term
List the 3 types of blood vessels.
Definition

Arteries

Veins

Capillaries

Term
Arteries carry __________ blood (away/towards) the heart.
Definition

Definition
deoxygenated, back
Term
T/F. Veins are thick walled.
Definition
False, thin walled
Term
How do veins move blood? What is the largest vein?
Definition
using valves, largest in Vena Cava
Term
Why are capillaries single celled?
Definition
for diffusion of gases and nutrients
Term

What do white blood cells do? How long do they live?

Definition

1.carry oxygen

2.120 days

3.protect body from invasion

4.months or years

Term
Matured red blood cells (have/don't have) a nucleus. Why or why not?
Definition
don't have since hemoglobin pushes it out
Term
Which type of blood cell IS outnumbered 500---1?
Definition

Term
What is the lifespan of a platelet? Platelets cause a ____ reaction. Example?
Definition

5-9 days

chain

clot blood and stop bleeding

Term
T/F. Platelets release proteins which form a mesh to stop bleeding.
Definition
True
Term
Lymph system is known as the ___ circulatory system.
Definition
2nd
Term

-Lymph capillaries absorb excess fluid and return it to blood stream

-Produces and maintains lymphocytes

 

 

What are the other 2 functions?

Definition

-Lymph capillaries absorb fats from small intestines and transport to blood stream

-Helps defend body againt pathogens

Term
_____ vessels are one way systems(with _____) that pick up excess fluid, send it through _____ nodes to filter it and return it back to the ________.
Definition

Lymph

valves

lymphnodes

bloodstream

Term
Describe how the lymphatic system and circulatory system are different.
Definition
the lymphatic system has no pump like the circulatory has, so it uses skelatal muscle contractions forcing lymph through the vessels.
