please help me guys please give me answer of this question plz

Explanation:
The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation).

What Are the Parts of the Respiratory System?The respiratory system includes the nose, mouth, throat, voice box, windpipe, and lungs.Air enters the respiratory system through the nose or the mouth. If it goes in the nostrils (also called nares), the air is warmed and humidified. Tiny hairs called cilia (SIL-ee-uh) protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose through the breathed air.

Tiny hairs called cilia (SIL-ee-uh) protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose through the breathed air.The two openings of the airway (the nasal cavity and the mouth) meet at the pharynx (FAR-inks), or throat, at the back of the nose and mouth. The pharynx is part of the digestive system as well as the respiratory system because it carries both food and air.
Answer:
a. Transport into capillaries:
Diffusion of gases takes place from higher to lower pressure until it's partial pressure reach in equilibrium.
- The partial pressure of O2 in pulmonary capillaries is high than alveoli hence O2 transport from alveoli into capillaries
b. In and our air passage:
The gases exchange occure at the area of in and out passage that is between the alveolar air and the blood.
c. Alveoli:
It consists of two layer-
1) simple squamous epithelial
2) capillary wall
1st layer is associate with dense network of capillaries
Both layers have similar structure and thin walled ad together they make respiratory membrane for exchange of gases between alveolar air and blood.
d. RBC's :
RBC's are also called erythrocyte. They are red colored circular, biconcave and enuecleated.
Their lifespan is of 120 days
RBC's are 1stly blur in colored but, in alveolar network of capillaries takes the O2 gas from the passage of alveoli and RBC's convert themself into red color due to presence of hemoglobin.
RBC's transport the gases and also maintain the pH and viscosity too.
Explanation:
The given diagram shows the processes takes place between alveoli and the capillaries.
