Red blood cells, also known as erythrocytes, are responsible for carrying oxygen in the bloodstream. They contain hemoglobin, a protein that binds to oxygen in the lungs and transports it to tissues throughout the body.
A hormone is the compound secreted into the bloodstream by one type of cell that acts to control the function of another type of cell.
A rocket has it's own supply of oxygen.
Oxygen is transported in the body primarily by binding to hemoglobin in red blood cells. It can also dissolve in the blood plasma to a lesser extent. Once in the bloodstream, oxygen is delivered to tissues and organs where it is needed for cellular respiration.
Essentially the air inhaled, which includes oxygen, passes through the various bronchi and briochioles until it reaches the aveoli. Here is where oxygen diffuses due to a concentration gradient. The oxygen must diffuse 5 layers before it enters a red blood cell. The red blood cell can now deliver it to tissues. At the same time, carbon dioxide diffuses through 5 layers to reach the aveolar space and can be exhaled the 5 layers are as follows: (1) type 1 aveolar cell, (2) basal lamina of type 1 aveolar cell, (3) basal lamina of endothelial cell, (4) endothelial cell, and (5) plasma membrane of the red blood cell. Oxygen diffuses from 1 to 5 and Carbon dioxide difuses from 5 to 1. Oxygen and carbon dioxide are essentially trading places. Note: basal lamina is connective tissue that a cell adheres to. Bronchi and bronchioles are the tubes which air flows. aveoli are small sacs of empty space, which is the site for gas exchange. drazx is the original author of this answer
Oxygen is primarily transported into blood cells by binding to hemoglobin molecules within red blood cells. This process occurs in the lungs where oxygen diffuses from the alveoli into the bloodstream and binds to hemoglobin, forming oxyhemoglobin.

This type of respiration is called internal respiration. In internal respiration, oxygen diffuses from the bloodstream into the cells of tissues, while carbon dioxide diffuses from the cells into the bloodstream.

A flat-shaped cell found in the lungs is likely to be a type of epithelial cell, such as a type I alveolar cell. These cells are responsible for gas exchange in the lungs, allowing oxygen to pass from the air into the bloodstream. Their thin, flat shape maximizes surface area for efficient gas exchange.

The pulmonary artery carries blood away from the heart and it is low in oxygen.
Red corpuscles (red blood cells) carry oxygen in the bloodstream.
