Step by Step. Write a set of directions for a red blood cell to deliver oxygen to the brain. Include all the words in the word bank. Lungs, Heart, Brain, Aorta, arteries, veins. Each word has to be used in a sentence in the correct order that it happens.

Explanation:

.1)Your AORTA pumps OXYGENATED blood out of your heart to your BRAIN

The aorta stretches across the back of your heart and pumps blood to your BRAIN

As oxygenated blood goes to your cells, it drops off oxygen and picks up waste

Cells in your BRAIN need oxygen so that they can perform cellular respiration to get energy

Blood also picks up carbon dioxide from the cells as the waste product of cellular respiration

2. DEOXYGENATED blood returns to your heart through the SUPERIOR VENA CAVA and INFERIOR VENA CAVA to your RIGHT ATRIUM

Capillaries separate oxygenated blood from deoxygenated blood and arteries from veins

After passing through the capillaries, blood is deoxygenated and needs to head back to the heart to be pumped to the lungs to pick up oxygen

The Superior Vena Cava is the vein that gets deoxygenated blood from the upper body and returns it to the heart

The Inferior Vena Cava is the vein that gets deoxygenated blood from the lower body and returns it to the heart

3. The right atrium pumps it to the RIGHT VENTRICLE

From the superior and inferior vena cava, blood goes through the Right Atrium

First, the SA Node (sinoatrial node) (pacemaker) sends electrical signals to pump blood from right atrium to right ventricle

Then, as blood enters the right ventricle, the AV Node (atrioventricular node) receives a signal to act as the gateway to the right ventricle

Blood goes through the tricuspid valve/right AV valve (makes sure blood flows in only one direction) as it enters the right ventricle

4. Your RIGHT VENTRICLE pumps deoxygenated blood up to your PULMONARY ARTERY, where it heads to lungs to pick up oxygen

First, the right ventricle pumps blood through your Pulmonary Valve (makes sure blood flows in only one direction)

Then, the Pulmonary Artery carries the blood away from the heart to the lungs for oxygen

5. DEOXYGENATED blood BECOMES OXYGENATED and drops off waste

Deoxygenated blood becomes oxygenated and arteries become veins in the capillaries

In the lungs, capillaries are tied around alveoli, which are little sacks storing the oxygen that we inhale

Oxygen is transferred into the blood and waste is transferred out of the blood through the capillaries

6. Oxygenated blood leaves the lungs and returns to the heart through the PULMONARY VEINS and enters the LEFT ATRIUM

Now that it’s oxygenated, it’s ready to go and get pumped back to the body!

7. The LEFT ATRIUM pumps blood to the LEFT VENTRICLE, and then it is pumped to the AORTA to do the same thing ALL OVER AGAIN

As it goes from left atrium to left ventricle, blood passes through the bicuspid valve/left AV valve (makes sure blood flows in only one direction)

Blood then is pumped from left ventricle through the aortic valve (makes sure blood flows in only one direction) back into the aorta to repeat the whole cycle again

Heart - lungs -arteries - capillaries - Veins

Explanation:

The step by step transfer of oxygen from red blood cells to the brain is as follows -

a) Heart - from the heart blood circulation starts and then it will go to lungs for taking up oxygen

b) Lungs - Lungs provide oxygen to the red blood cells

c) Arteries - Blood from lungs is sent to other parts of the body through arteries

d)  Capillaries - Capillaries exchange oxygen from blood with the cells of other body part and taken in carbon dioxide from them.

e) Veins - Blood then returns to the heart through the veins (
