Answer:

The correct answer is option - A, B, C, and D.

Explanation:

The adaptive immune system is also known as a specific immune system or acquired immune system is an immunization system that is made up of which is clonal as it expands rapidly the Lymphocytes that are T lymphocytes and B lymphocytes. The adaptive immune system also has memory this is the reason vaccination is used so it can generate antibodies and make memory cells. Vaccines induce the production of the immune cells or antibodies so it can be stated that it is inducible.

Thus, the correct answer is option - A, B, C, and D.

Explain the respiratory system of a frog and the importance of "vacularization" of the skin and the mesentery
fredd [130]

 The skin is composed of thin membranous tissue that is quite permeable to water and contains a large network of blood vessels. The thin membranous skin is allows the respiratory gases to readily diffuse directly down their gradients between the blood vessels and the surroundings. When the frog is out of the water, mucus glands in the skin keep the frog moist, which helps absorb dissolved oxygen from the air.

A frog may also breathe much like a human, by taking air in through their nostrils and down into their lungs. The mechanism of taking air into the lungs is however sligthly different than in humans. Frogs do not have ribs nor a diaphragm, which in humans helps serve in expand the chest and thereby decreasing the pressure in the lungs allowing outside air to flow in.

In order to draw air into its mouth the frog lowers the floor of its mouth, which causes the throat to expand. Then the nostrils open allowing air to enter the enlarged mouth. The nostrils then close and the air in the mouth is forced into the lungs by contraction of the floor of the mouth. To elimate the carbon dioxide in the lungs the floor of the mouth moves down, drawing the air out of the lungs and into the mouth. Finally the nostrils are opened and the floor of the mouth moved up pushing the air out of the nostrils.

Frogs also have a respiratory surface on the lining of their mouth on which gas exchange takes place readily. While at rest, this process is their predominate form of breathing, only fills the lungs occasionally. This is because the lungs, which only adults have, are poorly developed.

When the patient with emphysema was selected lung values changed (from those of the normal patient) in the spirogram are:

ERV, IRV, RV, FVC, FEV1, FEV1 %

<span>The reason behind the changes of these values are due to the loss or inability of electric recoil. A spirogram (graph like structure obtained by the respiratory movements) is measured by spirometer.</span>
