Q

Conduction System of Heart Route

A

1 - Electrical imuplse starts spontaneously at Sa node causing both atria to contract
2- Travels to Abu node at AV septum
3- Travels down right & left bundles in IV septum
4- Spreads out to myocardium through conducting fibres, causes ventricles to contract

Q

How are arteries named?

A

Depending on anatomical location, usually deep compared to veins and supply that territory

16
Q

What are the 4 parts of the aorta?

A

Ascending
Arch
Thoracic - Ascending
Abdominal - Descending

17
Q

How does the aorta receive blood?

A

At high pressure during systole
Arterial enters the aorta first
Elastic walls expand & elastic recoil maintain the peripheral flow during diastole

18
Q

What are the branches of the aorta?

A

Brachiocephalic Trunk
Left Common Carotid Artery
Left Subclavian Artery

19
Q

Brachiocephalic Trunk

A

Supplies head & neck

20
Q

Left Common Carotid Artery

A

Comes off arch of aorta

21
Q

Left Subclavian Artery

A

Comes off arch of aorta

22
Q

What can Arteriolar smooth muscle contraction do?

A

Reduce blood flow following an injury

23
Q

What is anastomosis

A

Connection between arteries
Alternative pathway for blood flow to supply the tissues distal to an arterial occulsion

24
Q

End Artery

A

The only aerial blood supply to a given area
Untreated occlusion can result in infarction of its territory

25
Q

Features of Veins

A

Thin walls that collapse when empty
Non-pulsatile
Have Valves
Have Tributaries

26
Q

Venous blood

A

Flows back to the heart

27
Q

What assisted Venous Return?

A

Venous Valves
Musculovenous Pump
Venae Comitantes

28
Q

What is the venous valves?

A

In limb veins, valves are present to ensure unidirectional flow back to heart against gravity

29
Q

What is the Musculovenous pump?

A

Contraction of skeletal muscles in lower limbs

30
Q

What are Venae Comitantes?

A

Small veins that run in parts or more with an artery in sheath
Arterial pulsation pushes venous blood along

31
Q

What are the 2 sets of veins?

A

Superfical & Deep

32
Q

What are the 2 main venous systems?

A

Portal & Systemic

33
Q

Capillaries

A

One layer of endothelium
Only one Rbc can pass through at a time
Allow for task metabolites & waste exchange

34
Q

Where is lymph carried to?

A

Venous angles in root of neck
Right lymphatic duct -> right venous angle
Thoracic duct - left venous angle
Superfical vessels -> deep vessels

35
Q

How does the lymphatic recycling system work?

A

Lymph drains to venous system
Venous angle where central veins from head/neck & upper limbs meet in root of neck
