d. sensory input from receptors in joints, neural input from the motor cortex, and other factors is the correct answer
Explanation:
- sensory input from receptors in joints, neural input from the motor cortex, and other factors stimulates increased respiration at the beginning of exercise.
- As we do exercise our muscles gets active, it produces lactic acid that enters the blood and hydrogen ions are a release that reduces the pH due to a decrease in the pH stimulates the sensory receptors to carry nerve impulses to respiratory muscles and this increase respiration at the beginning of the exercise.
- In medual the respiratory center is stimulated by increasing the carbon dioxide concentration.
Answer:
b. insertion of a cannula into the external iliac vein
Explanation:
A saphenous cutdown refers to a skin incision associated with insertion of a cannula into the external iliac vein.
It is a more invasive method of exposing the saphenous vein. A cut is made into the skin which is not very deep. A part of vein is exposed which is then cut out for the insertion of cannula. It does not stop the flow of blood, instead it just changes the course. It is also known as the circulatory blood flow.
