Blood

Question 1

Three types of blood vessels

Answer 1

• Arteries
• Veins
• Capillaries

Question 2

Arteries

Answer 2

Carry blood away from the heart

Question 3

Veins

Answer 3

Carry blood back to the heart

Question 4

Capillaries

Answer 4

Site of where exchanges of gases between cells and blood takes place

Question 5

Heart Rate

Answer 5

Amount of times the heart contracts per minutes

Question 6

Stroke Volume

Answer 6

Amount of blood ejected from the left ventricle with each heartbeat

Question 7

Cardiac Output

Answer 7

Amount of blood ejected from the left ventricle of the heart per minute

Question 8

Cardiac Output Equation

Answer 8

Cardiac Output = Stroke Volume x Heart Rate

Question 9

Blood role

Answer 9

Blood transports materials required for energy production, including oxygen and glucose, and byproducts of energy production such as carbon
dioxide and lactate, around the body

Question 10

Red blood cells

Answer 10

Transport oxygen to, and carbon dioxide from, the cells and muscles

Question 11

White blood cells

Answer 11

Pass through capillary walls into
the body cells to fight disease

Question 12

Platelets

Answer 12

Cause blood to clot when a blood
vessel is damaged

Question 13

Plasma

Answer 13

Provides the cells with proteins, salts, glucose, fats, antibodies and some oxygen.

Question 14

Systematic circulation

Answer 14

when oxygenated blood is transported from the heart via the left ventricle and aorta and circulated into the arteries around the body, and deoxygenated blood returns to the heart via the vena cava and into the right atrium

Question 15

Pulmonary circulation

Answer 15

when deoxygenated blood is transported away from the heart and circulated to the lungs via the right ventricle and pulmonary artery, and oxygenated blood returns to the heart via the pulmonary vein and into the left atrium

Question 16

Thermoregulation

Answer 16

Thermoregulation relates to the
maintenance of body temperature and the heat exchange that occurs between the body and the environment.

Question 17

Core temperature

Answer 17

36.5-37.5 centigrede

Question 18

Core temperature increase due to:

Answer 18

increased blood flow around the
body

muscle use and energy production

the environmental conditions that
an individual may exercise in, such
as heat and humidity.

Question 19

Mechanisms to control body temperature

Answer 19

sweating

shivering

controlling blood flow to the skin and
around the body.

Question 20

Vasodilation

Answer 20

When the body is too hot and there is need for heat loss, the cardiovascular system will automatically direct more blood flow through the vessels to the skin surface

Question 21

Vasoconstriction

Answer 21

When the body is too cold and there is need for heat retention, the cardiovascular system will restrict blood flow to the skin and redirect it to the internal organs, decreasing heat loss.

Question 22

Hypothermia

Answer 22

Hypothermia is a thermal risk associated with exercising in cold environmental conditions. It occurs when the body’s core temperature falls below 35 degrees Celsius.
