Q

What is the structure of Veins?

A

Structure of Veins
- Valves (Stops back flow of blood)
- Large lumens
- Has no pulse so blood travels smoothly
- Thin walls

Q

?What are the three types of Blood Vessels?

Study These Flashcards
A

Blood Vessels
- Veins
- Arteries
- Capillaries

22
Q

What is the function of Arteries?

Study These Flashcards
A

Arteries - Take blood Away from the Heart (Carries Oxygenated blood)

23
Q

What is the structure of Arteries?

Study These Flashcards
A

Structure of Arteries
- No valves
- Small lumens
- Has a pulse/Blood travels in spurts
- Thick + Elastic walls

24
Q

What is the function of Capillaries?

Study These Flashcards
A

Capillaries - Carries blood to and from the body’s cells

25
What is the structure of Capillaries?
Capillaries - Small blood vessels - One cell thick - Allow gaseous change
26
What is Capillarisation?
Capillarisation - The number of Capillaries increase with the amount of exercise
27
Which blood vessel has Large Lumens?
Veins have Large Lumens
28
Which blood vessel has Small Lumens?
Arteries have Small Lumens
29
Which blood vessel has Thick and Elastic Walls?
Arteries have Thick and Elastic Walls
30
Which blood vessel has Thin Walls?
Veins have Thin walls
31
Which blood vessel is one cell thick?
Capillaries are one cell thick
32
Which blood vessel takes blood Back to the Heart?
Veins take blood Back to the Heart
33
Which blood vessel takes blood Away from the Heart?
Arteries take blood Away from the Heart
34
Which blood vessel has Valves?
Veins have Valves
35
Which blood vessel does not have Valves?
Arteries do not have Valves
36
Which blood vessel has a pulse?
Arteries have a pulse
37
Which blood vessel does not have a pulse?
Veins have no pulse
38
How does blood travel in terms of blood vessels?
Blood travels from an Artery -> Arteriole -> Capillary -> Venule -> Vein
39
Which Pulmonary blood vessel carries blood at a low pressure?
The Pulmonary Vein carries blood at a Low Pressure
40
Which Pulmonary blood vessel carries blood at a high pressure?
The Pulmonary Artery carries blood at a High Pressure
41
What is the Double Circulatory System?
The Double Circulatory System is the two different circuits that the Heart consists of
42
What are the two circuits in the Double Circulatory System?
The two circuits in the Double Circulatory System is the Pulmonary Circuit and the Systemic Circuit
43
What is the Pulmonary Circuit in the Double Circulatory System?
The Pulmonary Circuit is the path of blood when it travels from the Heart and Lungs
44
What is the Systemic Circuit in the Double Circulatory System?
The Systemic Circuit is the path of blood when it travels from the Heart to the Body
45
What is the role of Blood Cells?
Blood Cells - Transport O2 to working muscles - Transport CO2 to the Lungs - Allow efficient gaseous exchange at the muscles, lungs, and alveoli
46
What is the Vascular Shunt Mechanism?
Vascular Shunt Mechanism - How greater amounts of blood can be directed to muscles during exercise ( Prioritises muscles when working)
47
What is Vasodilation?
Vasodilation - When Capillaries and Arteries dilate (expand) to allow greater blood flow. - This happens when a person is Hot
48
What is Vasoconstriction?
Vasoconstriction - When Capillaries and Arteries constrict to allow less movement of blood to muscles - (Prioritises organs when working) - Happens when a person is Cold
49
Give a sporting example of when the Vascular Shunt Mechanism is used
- There will be an increased blood supply to the quadriceps during a game of football - There will be a decreased blood supply to the digestive system (liver/kidney/intestines) during a game of football
50
What are the two components of the Vascular Shunt Mechanism?
The two components of the Vascular Shunt Mechanism is Vasodilation and Vasoconstriction
