Q

What are the 3 large branches of the AORTA?

A

1) BRACHIOCEPHALIC ARTERY
2) L. COMMON CAROTID ARTERY
3) L. SUBCLAVIAN ARTERY

24
Q

Which are the first BLOOD VESSELS to receive blood from the AORTA?

A

The CORONARY ARTERIES

25
Q

What is the CIRCLE OF WILLIS?

A

An arterial ring that circles around the PITUITARY GLAND, gives rise to the ANTERIOR, MIDDLE, and POSTERIOR CEREBRAL ARTERIES

26
Q

DEEP VEINS…

A

…typically travel alongside an artery of the same name

27
Q

VENOUS SINUSES…

A

…e.g in the HEART (CORONARY SINUS) or in the DURA MATER, there are several sinuses providing quick drainage of the BRAIN

28
Q

Via which two BLOOD VESSELS does the SYSTEMIC system return blood from the various non-digestive organs and tissues of the body?

A

The SUPERIOR or INFERIOR VENA CAVA

29
Q

Where do the CORONARY ARTERIES originate from?

A

The base of the AORTA

30
Q

What does CAD stand for?

A

CORONARY ARTERY DISEASE

31
Q

What is CORONARY ISCHEMIA?

A

Not having enough BLOOD through the CORONARY ARTERIES, can be a result of HEART DISEASE or HEART ATTACKS

32
Q

What is a MYOCARDIAL INFARCTION?

A

A HEART attack

33
Q

When could cause a MYOCARDIAL INFARCTION?

A

Dec. BLOOD flow to a part of the HEART

34
Q

What is does a CORONARY BYPASS GRAFT (CABG) do?

A

Redirects BLOOD around partially/fully blocked ARTERIES in the HWRAT to improve BLOOD flow

35
Q

Which 2 pairs of major ARTERIES supply OXYGENATED blood to the BRAIN

A

VERTEBRAL ARTERIES and INTERNAL CAROTID ARTERIES

36
Q

The VERTEBRAL ARTERIES pass through the TRANSVERSE FORAMINA of which bones?

A

The CERVICAL VERTEBRAE

37
Q

What does CVA stand for?

A

CEREBROVASCULAR ACCIDENT

38
Q

What is a more common term for a CEREBROVASCULAR ACCIDENT?

A

A STROKE

39
Q

Give 3 symptoms of a CVA

A

1) Sudden numbness or weakness on one side
2) Drooping of the facial muscles
3) Difficulty speaking
(F.A.S.T)

40
Q

Why is the MIDDLE CEREBRAL ARTERY a common site for a CVA?

A

Because the MIDDLE CEREBRAL ARTERY is located coming just off to the side of the CIRCLE OF WILLIS and the sharp turn is a site for blood turbulence.

41
Q

What is a HEMORRHAGIC STROKE?

A

A STROKE occurring from a ruptured BLOOD VESSEL

42
Q

What is a THROMBOTIC STROKE?

A

A STROKE occurring from blocked blood flow because of a clot
