Answer:
C reproductive cells ( sex cells)
For an animal to be extinct none more of that specific species must exist on Earth. This makes it impossible for that species to come back to life.
External respiration (correct answer) involves the exchange of oxygen and carbon dioxide within the environment.
The exchange of wastes through the skin is just called excretion by sweating.
There is no exchange of nutrients that occur in the lungs but rather absorption of nutrients is the function of the gastrointestinal tract.
The exchange of oxygen and carbon dioxide within the cell is called cellular respiration and involves carrying oxygen from the blood to the cell then the cell uses it as the final electron acceptor in the electron transport chain. The metabolic wastes of the cell, primarily carbon dioxide, goes now to the bloodstream to be exchanged for oxygen in the lungs.
The total blockade comes with the biggest potentially fatal complication of an epidural or intrathecal anesthesia. Many women choose this type of spinal epidural or intrathecal anesthesia during labor to block all labor pains. The primary symptom is hypotension. Hypotension is low blood pressure. Nausea is usually the first symptom of hypotension. A nurse will be able to intervene when the vital machine shows the blood pressure dropping. This why hospitals always have someone connected throughout labor to a vital signs machine when having an epidural or intrathecal anesthesia.
