1

What are the three main parts of the cardiovascular system

1. Heart
2. Vessels
3. Blood

2

What are the Three main functions of the blood

1. Transportation
2. Regulation
3. Protection

3

What does blood transport

1. Oxygen
2. CO2
3. nutrients
4. Hormones
5. Waste

4

What part of the blood transports oxygen and CO2

Red blood cells

5

What is the part of the blood that transports hormones, nutrients and waste

The plasma

6

What does the blood help the body to regulate

1. temperature
2. body pH
3. body fluid levels

7

What part of the blood helps the body regulate temperature

the plasma

8

How does the blood help protect the body

1. protection from infection
2. transports infection fighting antibodies
3. forms blood clots

9

What is the average blood volume in an adult

between 4-6 liters

10

what is the average temperature of the blood

38 degrees celcius
100.4 degrees farenheight

11

is blood more or less viscous than water

more

12

is blood acidic, neutral, or alkaline

slightly alkaline (pH = 7.35 - 7.45)

13

What is the hematocrit

a measurement of the percentage of blood that is made up of RBC's

14

What is the typical hematocrit for men, and for women

Men = 40% - 54%
Women = 37% - 47%

15

What are the typical percentages of blood composition of plasma, buffy coat, and Red blood cells

plasma = 55%
buffy coat = 1%
Red blood cells = 44%

16

What can cause changes to hematocrit naturally

1. hormone changes
2. altitude changes

17

What is the effect of blood doping

increased hematocrit, which is thought to favorably affect muscle performance

18

What are the two ways that people do blood doping

1. they remove and store a unit of blood, then wait for the body to replace the lost blood and reinject the blood back into the body
2. they use EPO (erythropoetin stimulates RBC production)

19

What can be a danger of blood doping

it increases the viscosity of the blood, which can lead to heart failure

20

What makes up plasma

1. Water
2. Proteins
3. Other solutes

21

What percentage of plasma is water, proteins, and other solutes

Water is 92%
Proteins are 7%
Other solutes are 1%

22

What makes up the buffy coat

platelets and leukocytes

23

What are the 4 main protein types in the blood

Albumins
Globulins
Fibrinogen
Regulatory proteins

24

list the blood plasma proteins from most abundent to least abundent

Albumins (60%)
Globulins (35%)
Fibrinogen (4%)
Regulatory proteins (1%)

25

What do albumins do in the blood

transport substances (fatty acids, thyroid, and steroid hormones)

26

What do globulins do in the blood

1. They are antibodies (immunoglobins)
2. Transport globulins (proteins)

27

What does fibrinogen do in the blood

they help form clots
they produce long-insoluble strands of fibrin

28

What are examples of regulatory proteins that can be found in blood plasma

insulin, prolactin, TSH, FSH, LH

29

what is found in RBCs (Red blood cells)

Hemoglobin

30

Are there nuclei, and mitochondria is RBCs or any organelles
