What are the steps of the cardiovascular system?

Answer 1

The passage of blood through the heart Step 1De-oxygenated blood (coloured purple in this diagram) returns to the heart through the large veins called the Venae Cavae. The blood enters the right auricle, and passes through the tricuspid valve into the right ventricle. It is then pumped through the semi-lunar valve into the pulmonary artery and into the lungs where it loses carbon dioxide and picks up fresh oxygen. Step 2 The oxygenated blood (coloured red in this diagram) returns to the heart from the lungs through the pulmonary vein into the left auricle. It passes through the bicuspid valve and into the left ventricle. It is pumped through the semi-lunar valve into the aorta, and out to the rest of the body through the arteries.

Answer 2

1. First blood is pumped around the body from the left ventricle
2. It is then pumped from the heart to the lungs where it gives up the Co2(carbon dioxide) and picks up oxygene
3. the oxygen rich blood then returns to the heart right atrium
4. When this blood reaches the cells, it provides them with oxygen and picks up carbon dioxide and other wastes
5. The blood is then pumped to the body, stoping by kidneys for the removal of the other wastes along the way
6. The blood, now full of wastes returns to the heart left atrium

Answer 3

Systole-Atria contract, forcing blood into venticles. Deoxygenated blood from body enters right ventricle. Oxygenated blood from lungs enter the left ventricle. Then ventricles contract forcing blood through arteries to the lungs and out the aorta to the rest of the body.

Diastole-Cycle ends, and heart relaxes, blood fills the atria and begins to flow passively into the ventricles.

Answer 4

1. oxygen-depleted blood enters the right atrium

2. blood enters the right ventricle

3. blood is pumped to the lungs to receive oxygen

4. blood enters the left atrium

5. blood enters the left ventricles

6. blood is pumped to the entire body

Answer 5

go through nose, into blood vessles. vessels carry the oxygen to the heart, the heart turns the oxygen onto blood and delivers to lungs hope this helped.

Answer 6

Arteries, veins, heart, capillaries, and blood... at least that's what it says on my textbook

Answer 7

uranus, vincent, Pizza, and chicken

Answer 8

it starts with the heart

Answer 9

dont care
