16
Q

These are red blood cells-RBC’s (“erythro” means “red”; “cyte” means “cell”)

A

Erythrocytes

17
Q

______ uses iron (Fe) to hold oxygen. (“heme” means “iron”)

Each RBC can hold 1 billion oxygen molecules.

A

Hemoglobin

18
Q

These are white blood cells – WBC’s (“leuko” means “white”)

They protect our bodies against invading organisms or materials.

A

Leukocytes

19
Q

These are pieces of RBC’s used for making clots.

A

Platelets

20
Q

These are for gas exchange with the environment.

A

Respiratory Systems

21
Q

(Oxygen in and Carbon dioxide out.)

Oxygen is need for cellular respiration; Carbon dioxide is the waste product of cellular respiration.

A

Gas Exchange

22
Q

This term refers to where the oxygen molecules are located. It is either water or air.

A

Respiratory Medium

23
Q

This term refers to where the gas exchange occurs.

A

Respiratory Surface

24
Q

Diffusion must occur across a ______ surface. Gases do not diffuse across dry surfaces.

A

wet

25
Q

A large surface area is needed to get large amounts of gas exchange to occur. ______ in the surface increases surface area within a small space.

A

Folds

26
Q

Gills, Lungs, Tracheal tubes, Skin, membranes are all ________ surfaces.

A

respiratory

27
Q

Works with the circulatory system ( That is why they are always located together.)

A

Respiratory system

28
Q

Mammalian Respiratory system is located in the ________ Cavity (Chest)

A

Thoracic

29
Q

These cavities warm, moisten, and clean the air using mucous and hairs.

A

Nostrils and Naval Cavity

30
Q

This is the back of mouth

A

Pharynx

31
Q

This is the top of trachea

A

Larynx

32
Q

This muscular flap covers the trachea by bending over the opening.

A

Epiglottis

33
Q

These vibrate to make sounds. (You can only talk while

exhaling because the moving air is causing the vibration by “catching” the wind, much like a parachute catches air.)

A

True and False Vocal Cords

34
Q

A.K.A. windpipe) It is protected by C- shaped cartilage rods on the front side.

A

Trachea

35
Q

(There is one for each lung.) Cartilage keeps them open for air to travel through.

A

Bronchi

36
Q

These carry air into each lobe of each lung.

A

Bronchioles

37
Q

This is an inflammation of the air ways.

A

Bronchitis

38
Q

This condition is having trouble breathing due to airways swelling shut.

A

Asthma

39
Q

means “air sacs” This is the site of gas exchange by diffusion. (If it is a wet surface.) They are only one cell layer thick which allows for rapid diffusion of gases. They are surrounded by capillary beds. (This makes it 2 cell layers thick. It leads to rapid diffusion in and out.) WBCs that keep these areas clean. (Smoking? Kills the WBCs.)

A

Alveoli
