Nostrils-Pharynx-Trachea(Wind Pipe)-Bronchi-Bronchioles-Alveoli
External Nares (Nostrils) --> Nasal Cavity --> Inferior, Superior, & Middle Nasal Conchae --> Pharynx --> Larynx --> Trachea --> Primary Bronchi (Left & Right) --> Hilus --> Bronchioles --> Respiratory Bronchioles --> Alveolar Ducts --> Alveoli (the grape-like sacs) --> the the "spider web" of Pulmonary Capillaries.
After entering it takes the left pump after entering
Yes, and back again, having picked up oxygen and dumped CO2.

The blood flows from the veins into the vena cava (inferior and superior) then into the right atrium. The right side of the heart sends the blood to the lungs to exchange carbon dioxide for oxygen.
The heart pumps your blood (cardio), into your lungs (respitory), to give them oxygen. Then it makes itsway around the body to supply oxygen to where it is needed. Then then new blood, without oxygen, goes on the exact same path.
The path followed by the blood when it supplies and drains the heart muscle
The path followed by the blood when it supplies and drains the heart muscle
The path of the blood has a definite purpose--to supply the blood with oxygen and deliver it to the body's cells. The blood carries oxygen to the body's cells and returns for more. When blood enters the right atrium of the heart, it is returning from the body where it has dropped off its supply of oxygen via osmosis and diffusion into body cells. At the same time, it has picked up waste in the form of carbon dioxide. You can think of the atrium as the "entry way" to the heart.

Plant releases oxygen. Oxygen molecules diffuse. Bear inhales.
