Question

Can someone please help me???
Describe the voyage of a red blood cell through the circulatory system.

Answer 1

The alveoli are in the lungs. This is where the red blood cell releases carbon dioxide from the car and picks up an oxygen passenger. The seats where the oxygen sits is the hemoglobin.

The heart pumps the blood so the car is always moving in one direction.

The roads that leave the heart are called arteries. These are the roads where the red blood cells have oxygen as passengers. The roads that return to the heart are called veins. Capillaries are tiny roads.

White blood cells are like the firefighters and ambulances. When there is an infection, the white blood cells rush to the scene.

Bone marrow is where red blood cells are made.

Platelets help stop bleeding. If you ever had a scab form after a cut, that was the work of platelets.
