Answer 14

Amphibian has no septum and has incomplete seperation
Reptile has partial septum and has partial seperation
Human has a full septum and has full separation

Question 15

Flow of blood in fish

Answer 15

Atrium - Ventricle - Artery - Gill capillaries (Is oxygenated) - Systematic capillaries (is used and deoxygenated) - vein - repeat

Question 16

Flow of blood in amphibians and reptiles

Answer 16

Systematic capillaries(deoxygenates) - right atrium - ventricle - lung capillaries and skin (Oxygenates) - left atrium - ventricle- repeat

Question 17

Flow of blood in humans

Answer 17

Inferior or superior Vena Cava
Right Atrium
Tricuspid valve
Right ventricle
Pulmonary semilunar valve
Pulmonary artery
Lung capillaries (Oxygenates blood)
Pulmonary vein
Left atrium
Bicuspid Valve
Left Ventricle
Aortic semilunar valve
Aorta
Systematic capillaries (Deoxygenates blood)

Question 18

Pulmonary circulation vs Systematic circulation

Answer 18

first - De brought to lungs for gas exchange
second - Ox brought to systematic capillaries for gas exchange

Question 19

Function of Aorta

Answer 19

The main artery transporting oxygenated blood to body

Question 20

Function and type of Vena Cava

Answer 20

Inferior (bottom) and superior (above)
Main vein transporting deoxygenated blood to heart

Question 21

Function of Pulmonary artery

Answer 21

Transport deoxygenated blood from heart to lungs

Question 22

Pulmonary veins

Answer 22

Transport oxygenated blood from lungs to heart

Question 23

Semilunar valves location and function and type

Answer 23

Pulmonary semilunar valves - located at base of pulmonary artery
aortic semilunar valves - located at base of aorta
Ensures the blood flowing out of heart doesn’t flow back to ventricle when it relaxes

Question 24

Tricuspid valve location and function and characteristic

Answer 24

Between right atrium and right ventricle
Ensure blood flow into right ventricle does not flow back into right atrium
Has three leaflets

Question 25

Septum

Answer 25

Separate left part and right part and oxygenated and de blood

Question 26

Bicuspid valve location and function

Answer 26

located between left atrium and ventricle
Blood flows into left ventricle does not flow back into left atrium
