Soc 16- The Structure Of The Blood Vessles And Blood Distrubution

Question 1

Veins

Answer 1

Carry deoxygenated blood back into the heart

Question 2

Veins 4 characteristics

Answer 2

Veins carry blood into the heart
Veins have much thinner walls
Veins contain many valves
Pulmonary veins carry oxygenated blood

Question 3

Why is the pulmonary vein is different to other veins

Answer 3

As it carries oxygenated blood from the lungs back to the heart

Question 4

Why do veins contain many valves

Answer 4

helps deoxygenated blood flow to the heart

Question 5

Arteries 4 main characteristics

Answer 5

Arteries takes deoxygenated blood away from the heart

Arteries have thick walls

The pulomnary artery carries deoxygenated blood from the heart to lungs

They channel the blood flows through called the lumen can widen to allow more blood through to the working muscles

Question 6

Whats the name of the channel that blood travels through in order to reach the working muscles

Answer 6

Lumen - can widen to allow more blood through so when you exercise it can reach the working muscle.

Question 7

How is the pulmonary arterie different from other arteries

Answer 7

It carries deoxygented blood from the heart to the lungs

Question 8

4 main characteristics of the Capillaries

Answer 8

Microscopic vessle- one cell thick

At one end the capillaries carry deoxygenated blood which transfers oxygen and nutrients to muscles

Capillaries are where gaseous exchange takes place

Capillaries carry deoxygenated blood into the veins, picking up waste products and taking them around the body to dispose of them

Question 9

How thick are the Capillaries vessles

Answer 9

Microscopic just one cell thick

Question 10

Immune system

Answer 10

The structures and process in your body that stop diseases

Question 11

Thrombokinase

Answer 11

Substance involved in blood clotting process

Question 12

Plasma

Answer 12

The fluid part of blood

Question 13

Erythrocyte

Answer 13

Red blood cell

Question 14

Haemogoblin

Answer 14

A red protein in the blood that transports oxygen

Question 15

Anaemia

Answer 15

A condition where there is a lack of red red cells or haemogoblin in the blood

Question 16

Pathogen

Answer 16

An agent that causes disease, such a virus

Question 17

Antibody

Answer 17

Chemical that destroyd a pathogen

Question 18

Blood pressure

Answer 18

Is a measure of the force that yout heart uses to pump the blood around your body

Question 19

What are the 4 components that blood is made up of

Answer 19

Red blood cells
White blood cells
Platlets
Plasma

Question 20

What do red blood cells contain

Answer 20

They contain haemogoblin, which stores oxygen and carbon dioxide

Question 21

What do white blood cells produce

Answer 21

They produce antibodies to fight againts infection and diseases

Question 22

What do the white blood cells do to help protect the body from diseases

Answer 22

The white blood cells help protect the bodys immune system from viruses and bacteria

Question 23

Where are platelets formed

Answer 23

Blood platelets are formed in bone marrow

Question 24

Platelets

Answer 24

Tiny fragments that clump together to help blood clot and stop bleeding

Question 25

What is the bodys first line of defence when repairing a wound

Answer 25

The blood is the first line of defence in the repair of a wound

Question 26

What happens when a blood vessle gets cut

Answer 26

Platelets rush to the area and swell into irregular shapes, they become sticky and act as a plug

Question 27

Whats the main role of the plasma

Answer 27

The plasma takes oxygen, nutrients,hormones and protiens to the parts of the body that need it

Question 28

Where do cells up their waste prodcuts in

Answer 28

Cells put thier wast prodcuts into the plasma then helps remove the wast from the body

Question 29

Capillaries main characteristics

Answer 29

Microscopic vessles Carry oxygenated blood Carry deoxygenated blood Are where gaseous exhange takes place

Question 30

What are the main vessles of the heat

Answer 30

The lungs and the body

Question 31

Double circulatory system

Answer 31

A double chemistry sysetm is one where the blood has to pass through the heart on eah crcuit of the body

Question 32

Double circulatory system

Answer 32

A double chemistry sysetm is one where the blood has to pass throught the heart on eah crcuit of the body

Question 33

The main 2 atriums of the heart

Answer 33

Left atrium and right artrium

Question 34

2 main ventricles of the heart

Answer 34

Left ventricle and right ventricle

Question 35

3 main valves of the heart

Answer 35

Semi-lunar valves Tricuspid valve Bicuspid valve

Question 36

4 main blood flow and air flow entrences of the heart

Answer 36

Pulonary artery Pulmonary vein Aorta Vena cava

Question 37

Explain how deoxygenated blood gets oxygenated

Answer 37

Deoxygenated blood enters the right side of the heart, is pumped to the lungs for oxygen, then returns to the left side of the heart, which pumps the now oxygenated blood through the aorta to the body.
