The partial pressure of oxygen in blood in the pulmonary artery.Explanation / Answer
31. When you become sick
A. Active ,acquired natural immunity is gained.
As we come in contact to a pathogen we produce antibodies and it is called active immunity. And induced is from vaccination but by infection it is natural
32. When arterial blood pressure increases
A. Net filteration pressure increases.
It increases the hydroststic pressure but colloid osmotic pressure is by the protein content and it is constant. So the net pressure of filetration increases.
33. The less likely function of respiratory system is
D. It prevents choking.
Because it is prevented by epiglottis. Which flattens and cover the trachea.
34. The correct statement is
B. The supressor cells limits the degree of immune system response.
All other statements are false.
The supressor t cells checks the antibody production by other lymphoid cells and thus prevent the over activity of immune system.
