Fill in the following flowchart to show the pathway of a red blood cell as
Alla [95]

Answer:

1. The pathway of a red blood cell from the right ventricle to the brain is:

<em>Right ventricle → pulmonary arteries → lungs → pulmonary veins → left atrium → left ventricle → artery aorta → arterial vessels → brain .</em>

2. The substance that forms hemoglobin in red blood cells when it passes through the lungs is oxyhemoglobin.

Explanation:

Red blood cells are structures present in the blood, whose function is to transport oxygen (O₂) and carbon dioxide (CO₂). This process requires travel throughout the body, through the blood vessels, and gas exchange at the pulmonary and tissue level.

1. A red blood cell in the right ventricle contains carbon dioxide and must pass to the lungs to be oxygenated. The route it takes from there includes Right ventricle (minor circulation) → pulmonary arteries → lungs → pulmonary veins → left atrium → left ventricle → (joining the major circulation) artery aorta → arterial vessels → brain .

2. The red blood cell or erythrocyte contains a molecule, called hemoglobin, which has an iron core that allows it to bind to O₂ and CO₂ in order to transport them. The affinity for one molecule or another depends on the presence of a certain gas in a certain place.

When the red blood cell passes through the lungs, the concentration of O₂ is higher than CO₂, so the latter is released and O₂ binds to hemoglobin, a conjugation that is called oxyhemoglobin.

Cells need oxygen to make energy. Oxygen-rich blood is transported to tissues. When the oxygen is dropped off, it needs to move
igor_vitrenko [27]

Answer: <u>Capillaries </u>

Explanation: There are two kinds of vessels which carry the blood throughout the body. These are veins and arteries. Now apart from these two, there is a third type which is called as capillaries, which are the connecting vessels between arteries and veins. These are relatively thinner and allow exchange of gases between tissues and the blood. Therefore, arteries and veins are incorrect options.

Heart is the pumping organ, and its function is to pump the blood to every cell of the body, so this can't be correct option.
