Circulatory System and Pathway of Blood through the heart

Question 1

Answer 1

away

Question 2

Veins carry blood __ the heart

Answer 2

to

Question 3

How does deoxygenated blood travel from the toe to the heart

Answer 3

Starts in the inferior vena cava,

then blood enters the right atrium,

blood is then contracted and pushed the blood to the Tricuspid Valve, and into the Right Ventricle

then blood is pumped through the Pulmonary Valve to the Pulmonary Artery which is taken to the Lungs

and now the blood is OXYGENATED!

Question 4

How does oxygenated blood travel through the body?

Answer 4

It starts in the LUNGS,

then travels through a Pulmonary Vein to the Left Atrium

the left atrium contracts and the blood travels through the Mitral Valve (aka bicuspid valve) and then into the Left Ventricle

the left ventricle contracts and pumps the blood through the Artic Valve and out a major artery called the Aorta
