A
  • It assists with the maturation of the immune system in young rats

6
Q

Function of the left anterior vena cava

A

Carries deoxygenated blood from the right side of the body (from the brain to the lungs) to the heart

7
Q

Function of the posterior vena cava

A

Carries deoxygenated blood from the bottom/ tail of the body to the heart

8
Q

Function of the left pulmonary vein

A

Transports oxygenated blood from the lungs to the left atrium of the heart

9
Q

Function of the right pulmonary vein

A

Transports oxygenated blood from the lungs to the left atrium of the heart

10
Q

How do you account for the differences in thickness

A
  • ventricles = thicker muscular wall = blood pumped out at greater pressure to rest of body
11
Q

Why are veins darker in colour and thinner walled

A
  • deoxygenated blood = darker in colour

- lower pressure = thinner walls

12
Q

Which venous system drains the alimentary canal and it’s associated organs?

A

The portal venous system

13
Q

What causes asymmetry between the right and left adrenal veins

A

Look for answer

14

A
  • makes, stores and releases thyroxin

= aids in metabolic activities

15
