Question 1

How is short term cont of blood pressure achieved

Answer 1

Via baroreceptors in carotid sinus and aortic arch detecting changes and sending signals to medulla oblongata

Question 2

How is blood controlled long term

Answer 2

Via kidneys and hormones of Vasopressin (ADH) and RAAS

Question 3

Heart chamber carrying deoxygenated and oxygenated blood

Answer 3

Left atrium, right atrium

Question 5

Answer 5

Left ventricle

Question 6

Arterial aanatomisis

Answer 6

A connection between 2 or more arteries to back up just in case one js blocked

Question 7

Closing opening aortic valves

Question 8

8 large blood vessels at the heart

Answer 8

Superior vena cava
Inferior vena cava
Pulmonary trunk
Aorta

Left pulmonary veins x2

Question 9

Pressures that drive filtration in capillary outwards?

Answer 9

Interstitial fluid colloid osmotic
Capillary hydrostatic

Question 10

Pressures that drive reabsorption inwards?

Answer 10

Capillary osmotic pressure
Interstitial hydrostatic

Question 11

Alternative name for av valve

Answer 11

L: bicupid and mitral
R: tricupid

Question 12

Calculate stroke volume, CO, MBP, PP

Answer 12

SV= EDV- ESV

CO = HR x SV

MBP= DBP + (1/3 PP)

PP= SBP - DBP

Question 13

HOW TO increase SV

Answer 13

Inc pre load EDC
Dec afterload Arterial pressyre
Increase contractility
