Answer:
pulmonary ventilation and external respiration
Explanation:
Respiration includes pulmonary ventilation, external respiration, and internal respiration. Pulmonary ventilation is also called breathing and is the process of flow of air into and out of the lungs. It includes the flow of air between the atmosphere and the alveoli of the lungs and is driven by alternating pressure differences created by contraction and relaxation of respiratory muscles.
External respiration is also called pulmonary respiration. It refers to the exchange of gases between the alveoli of the lungs and the blood in pulmonary capillaries. The exchange occurs through the respiratory membrane. External respiration males the capillary blood rich in O2. The capillary blood loses CO2 during the process.
Answer:
The arteries (red) carry oxygen and nutrients away from your heart, to your body's tissues. The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body's tissues.

This species that we would be killing off is innocent and not volunteering for this.
Water stratification is a phenomenon in which regions of water with different properties, such as salinity, oxygen content, density and temperature, form barriers to mixing of the water.
These barriers also create channels, referred to as sound fixing and ranging (SOFAR) channels. In these channels, the sound has a specified path. It travels slower than normal, but due to reduced dissipation to the surroundings, the sound travels for larger distances.
