Question

how are Oxygen and Carbon dioxide exchange in our body during respiration ​

Answer 1

Answer:

read below

Explanation:

We breathe, so the air is full of oxygen (high concentration)

- The air will enter the alveolus (ball structure above!)

- Due to its high concentration, oxygen will absorb into the capillaries as there is a difference in slope.

- Oxygen combines with red blood cells to form OKSIHEMOGLOBIN

- The blood will go to the body cells

- On the other hand, oxygen will be absorbed by the body's cells as there is a slope of diffusion too.

AND

- The blood will absorb the carbon dioxide present in the cell

- The blood will then return to the base of the lungs, and will exchange carbon dioxide with oxygen in the alveolus

and the process is repeated, and again, and again, and again ...

Answer 2

Answer:

The primary function of the respiratory system is to exchange oxygen and carbon dioxide. Inhaled oxygen enters the lungs and reaches the alveoli. ... Oxygen passes quickly through this air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled.

Explanation:

Oxygenated blood travels from the lungs through the pulmonary veins and into the left side of the heart, which pumps the blood to the rest of the body (see Biology of the Heart and Blood Vessels: Function of the Heart). Oxygen-deficient, carbon dioxide-rich blood returns to the right side of the heart through two large veins, the superior vena cava and the inferior vena cava. Then the blood is pumped through the pulmonary artery to the lungs, where it picks up oxygen and releases carbon dioxide (see Biology of the Heart and Blood Vessels: Function of the Heart).
