1If blood were to travel from the heart to the big toe, outline the major vessels it passes through after leaving the left ventricle.
- AAorta > Abdominal aorta > Common Iliac Artery > External Iliac Artery > Femoral Artery > Popliteal Artery > Posterior Tibial Artery

- AGreat saphenous, deep
- BGreat saphenous, superficial
- CPopliteal, deep

3We have [blank_start]5[blank_end] jugular veins. The right and left [blank_start]internal[blank_end] jugular vein, the right and left external jugular vein, and the [blank_start]anterior[blank_end] jugular vein.
We only have [blank_start]4[blank_end] carotid arteries, though: the right and left internal, and right and left [blank_start]external[blank_end].- A5
- B4
- Canterior
- Dposterior
- Einternal
- Fexternal
4Which sub-layer and layer of the blood vessels could be described as "A simple squamous epithelium
which lines the lumen of all vessels."- ASub-endothelium of the Tunica Intima
- BEndothelium of the Tunica Media
- CEndothelium of the Tunica Intima
- DInternal Elastic Lamina of Tunica Adventitia
5What is the structure and function of the sub-endothelium of the Tunica Intima?
- AA sparse pad of loose FCT, to cushion the endothelium.
- BA sparse pad of loose FCT, to prevent clotting
- CA simple squamous epithelium, to prevent clotting
- DA condensed sheet of elastic tissue, to reinforce the endothelium.
6The IEL (Internal elastic lamina) of the tunica intima is well developed in veins and less developed in arteries.
- AVerdadero
- BFalso
7The Tunica Media is mainly:
- ASmooth muscle
- BSquamous Epithelium
- CLoose FCT
8The Tunica Media has a [blank_start]variable[blank_end] content of connective tissue fibres, mainly elastin and [blank_start]collagen[blank_end].
Thickness of the media is proportional to both vessel diameter and [blank_start]blood pressure[blank_end], so is typically thickest in [blank_start]arteries[blank_end].- Avariable
- Bconstant
- Ccollagen
- Dkeratin
- Eblood pressure
- Fvolume
- Garteries
- Hveins
9Choose the correct statements about the Tuinca Adventitia.
- AIt is mainly loose FCT
- BIt is mainly smooth muscle
- CIt has a high elastin content
- DIt has a variable collagen content
- EIt contains the vasa vasorum
- FIt contains lymphatics and autonomics.
10The Tunica Media is often the thickest layer of veins.
- AVerdadero
- BFalso
11The Tunica Media often has two distinct layers in veins, and is thin compared to the Tunica Media in arteries.
- AVerdadero
- BFalso
12A 'vascular bundle' contains:
- Anerves, arteries, veins
- Barteries, veins, capillaries
- Carteries, veins, lymphatics
13Capillaries are the exchange site of the blood vascular system. They thus need walls that are very [blank_start]thin[blank_end], smooth and [blank_start]slow[blank_end] blood flow, and a [blank_start]large[blank_end] total cross sectional area.
- Athin
- Bthick
- Cslow
- Dquick
- Elarge
- Fsmall
14Precapillary sphincters are composed of [blank_start]smooth muscle[blank_end] cells. They [blank_start]limit[blank_end] access to a local capillary bed and are controlled [blank_start]autonomically[blank_end].
- Asmooth muscle
- Bepithelial
- Cautonomically
- Dsomatically
- Elimit
- Fcontrol
15Epithelial cells of the capillary wall make intercellular junctions to themselves.
- AVerdadero
- BFalso
16Continuous capillaries are the most [blank_start]common[blank_end]. They are tight and not meant to leak, and can be found in [blank_start]skeletal and cardiac muscle.[blank_end]
Fenestrated capillaries have fenestrations—pores [blank_start]smaller[blank_end] than cells—in their inner wall, but have a basement membrane which is still intact. An example of where these are needed is [blank_start]the kidney's glomerulus.[blank_end]
Sinusoidal capillaries are leaky, with many holes and pores and an only partially intact basement membrane. They are also the only type of capillary which is wide enough for [blank_start]more than one cell[blank_end]. They can be found in [blank_start]the liver[blank_end].- Acommon
- Bskeletal and cardiac muscle.
- Cthe liver
- Dsmaller
- Elarger
- Fthe kidney's glomerulus.
- Gmore than one cell
17Which of these could NOT be a distinguishing feature between veins and lymph channels?
- Aone way valves vs. no valves
- Bred blood cells vs. no red blood cells
- Cthin walls vs. thick walls
18Which of these is not a function of lymph?
- ADrainage of excess fluid and plasma proteins from tissues back to the blood
- BFiltering and immune response to antigens
- CFat absorption from intestine
- DProviding nutrients and removing metabolic waste from tissue
19Right axillary nodes and right cervical nodes drain into the [blank_start]right lymphatic duct[blank_end], which drains into the [blank_start]right subclavian vein[blank_end].
- Aright lymphatic duct
- Bcentral lymphatic drainage
- Cright subclavian vein
- Dright subclavian artery
20Lymph node structure could be described as trabecular.
- AVerdadero
- BFalso
21Label the sides/pumps of the heart.
- Aright
- Bleft
22Which of these methods could increase the force of contraction of the heart?
- AIncrease myocyte recruitment
- BIncrease cytosolic Ca++ to increase cross bridge formation
23What could explain a calcium leak in heart cells?
- AHealthy cells being under forceful contraction.
- BUnhealthy cells not able to contract forcefully enough.
24Actin is needed to uncouple cross bridges.
- AVerdadero
- BFalso
25The heart twists and contorts as it contracts. What is the structural explanation for this and what advantages does it present?
- ACardiac muscle fibres in helical pattern, increased efficiency and force of contraction
- BCardiac muscle fibres in helical pattern, decreased energy expenditure when contracting
- CCardiac muscle fibres in a perpendicular pattern, increased efficiency and force of contraction
- DCardiac muscle fibres in a perpendicular pattern, decreased energy expenditure when contracting
26Diastole is [blank_start]two[blank_end] "phases" of the cardiac cycle while systole is [blank_start]three[blank_end]. More time is spent in [blank_start]diastole[blank_end].
- Atwo
- Bthree
- Cdiastole
- Dsystole
27The mean arterial pressure can be found lying closer to systole on a graph.
- AVerdadero
- BFalso
28Pulmonary blood pressure is much [blank_start]lower[blank_end] than systemic blood pressure because the pulmonary circuit is [blank_start]shorter[blank_end] and has a [blank_start]smaller[blank_end] volume.
- Alower
- Bhigher
- Cshorter
- Dlonger
- Esmaller
- Flarger
29Which wave travels faster(after ejection from the aorta)?
- APressure wave
- BBlood wave
30How can pulmonary and systemic blood flows be equal when their respective pressures are so different?
- AResistance is higher in the pulmonary circuit
- BResistance is higher in the systemic circuit.
