Chapter 6 (Composition of Blood)

Question 1

What are the components of blood?

Answer 1

Plasma, red and white blood cells, platelets

Question 2

Plasma

Answer 2

Watery salty fluid that makes up more than half of the body’s blood volume. Red, white blood cells and platelets are carried in the plasma.

Question 3

What waste dissolves in plasma in order to be transported back to the lungs?

Answer 3

carbon dioxide from cells.

Question 4

Red blood cells (RBC, Erythrocytes, red corpuscles)

Answer 4

carry oxygen to tissues. hemoglobin molecules on these cells also provide the the red color in the blood.

Question 5

White blood cells (WBC, leukocytes, white corpuscles0

Answer 5

involved in destroying microorganisms (germs) and producing substances called antibodies.

Question 6

Antibodies

Answer 6

help body resist infection

Question 7

Platelets

Answer 7

membrane enclosed fragments of specialized cells.

Question 8

what do platelets do when activated?

Answer 8

they release chemical clotting factors needed to form blood clots

Question 9

what are 5 different types of white blood cells?

Answer 9

Eosinophil
Basophil
Monocyte
lymphocyte
neutrophil

Question 10

when is a pulse formed?

Answer 10

when left ventricle contracts sending pressure wave through the arteries.

Question 11

primary arteries (3) where pulse is taken for vital signs or CPR

Answer 11

Carotid, brachial, radial arteries

Question 12

where to check for circulation in lower extremities

Answer 12

posterior tibial and dorsal pedis

Question 13

the radial, brachial, posterior tibial and dorsals pedis are called peripheral pulses, why?

Answer 13

bc they can be felt in the periphery, or outer reaches, of the body

Question 14

Carotid and femoral pulses are called?

Answer 14

central pulses bc they can be felt in the central part go the body.

Question 15

central pulses can be felt even when _______ ______ cannot

Answer 15

peripheral pulses

Question 16

Blood pressure

Answer 16

the force blood exerts against the walls of blood vessels. (usually arterial blood pressure)

Question 17

Systolic blood pressure

Answer 17

The pressure created in the arteries when the left ventricle contracts and forces blood out into circulation

Question 18

diastolic blood pressure

Answer 18

the pressure remaining in the arteries when the left ventricle is relaxed and filling

Question 19

T or F. the systolic pressure is reported first (120), and diastolic second (80) to result in 120/80

Answer 19

True

Question 20

Perfusion

Answer 20

the passage of blood, a blood substitute, or other fluid through the blood vessels or other natural channels in an organ or tissue.

Question 21

hyperprofusion (shock)

Answer 21

inadequate perfusion. inadequate circulation of blood.

Question 22

cardiopulmonary system

Answer 22

respiratory system and cardiovascular system together

Question 23

Glucose is converted into what by the cells?

Answer 23

energy in the form of adenosine triphosphate (ATP)

Question 24

what is the process of conversion from glucose called?

Answer 24

aerobic metabolism

Question 25

When oxygen is not present in sufficient supply, the process of glucose conversion will shift to what?

Answer 25

anaerobic metabolism. produces less energy and more waste products such as lactic acid

Question 26

what do waste products do?

Answer 26

make the body more acidotic

Question 27

Acidosis injures the body’s what?

Answer 27

cells and limits bloods ability to carry oxygen

Question 28

The coupling of sufficient air with sufficient blood is called what?

Answer 28

ventilation perfusion match (V/Q match)

Question 29

what is a condition that reduces the amount of oxygen carrying red-blood cells?

Answer 29

anemia

Question 30

consider anything that threatens the normal function of ____________ system to be a threat to quality profusion

Answer 30

cardiopulmonary (heart and lungs)
