Question

Which sequence correctly shows oxygen movement during respiration?


capillaries, alveoli, body cells


alveoli, capillaries, body cells


alveoli, body cells, capillaries


body cells, capillaries, alveoli

Answer 1

Answer:

Explanation:

During resporation process the movement of oxygen takes place from the Alveoli to the capillaries and at last to the body cells. The alveoli refer to the tiny air sacs present in the lungs which help in the rapid movement of air circualtion.

These tiny air sacs are actually surrounded by a number of blood vessels which are referred to as the capillaries. Both capillaries and alveoli have thin walls which allows for a proper passing of the oxygen into the blood.

Answer 2

alveoli, capillaries, body cells shows oxygen movement during respiration

Explanation:

• The main function of respiratory system is to take in oxygen and eliminate the carbon dioxide that enters the lungs and reaches the alveoli.

• The layers of the thick cells that surrounds the alveoli and capillaries are one cell thicks and are close to each other.

• The exchange of the gases takes place in millions of alveoli in the lungs and the capabilities that envelop them

• Thus the inhaled O2 moves from the alveoli to the blood in the capillaries and form were the carbon dioxide moves out and of the capillaries into the air through the alveoli.

• Hence the oxygenated blood flows from the lungs to the pulmonary veins and then enters the left part of the heart, which pumps the blood to other parts of body.
