Answer 1

Arteries

Question 2

Which blood vessels carry blood from lungs to the heart

Answer 2

Veins

Question 3

Name the structure of the heart

Answer 3

Superior vena cava
Inferior vena cava
Right atrium
Left atrium
Right ventricle
Left ventricle
Triscupid valve
Pulmonic valve
Biscupid valve or mittal valve
Aortic valve

Question 4

Muscles of the heart

Answer 4

S node
AV node
Purkinje Fibre
Bundle of His Tawara branches

Question 5

How does blood flow through the heart

Answer 5

The superior vena cava collects deoxygenated blood form the upper body and inferior vena cava collects deoxygenated blood from the lower body which is together collected into the right atrium.
Then blood is ejected to right ventricle through triscupid valve.
Blood is then contracted through the pulmonary valve to the pulmonary artery which divided into left and right pulmonary arteries to the respective lungs where gas exchange occurs in the alveoli.
Then the Oxygenated blood is transported through the pulmonary veins from the lungs to the left atrium which contracts through the biscupid valve to enter the left ventricle. Blood is then ejected through the aortic valve to the aorta where is transported to the rest of the body parts.
