B lymphocytes get their name because they were initially identified in the Bursa of Fabricius, a structure present in birds.

Option D is accurate because “hemoglobin,” which boosts blood’s ability to carry oxygen by roughly 75 times, is the most significant protein found in many animals, including humans. Both Punjabi and Federal books contain this information.

In the circumstances, this choice is the appropriate one. The immune response in which plasma cells produce antibodies is referred to as the humoral response. In this case, β-cells are generating plasma cells that produce and release antibodies into tissue fluid and blood plasma. The procedure described in the sentence is appropriately described by this.

Since hemoglobin is 98% saturated at an oxygen tension of 115 mm mercury, there are 19.6 (approximately 20) milliliters of oxygen per 100 milliliters of blood.

The heart’s pacemaker is known as the sinoatrial (SA) node. The heart’s rhythm is set by a tiny cluster of cells in the right atrium that produce electrical impulses. For this reason, the SA node is frequently called the heart’s natural pacemaker.

‘Active immunity’ is described in the scenario.

When the body is exposed to an antigen, it produces memory cells that provide lifelong or long-lasting immunity against the specific agent. This process is known as “active immunity.” It might take a while for this response to form.

This is not the same as “passive immunity,” in which the body produces its own antibodies to fight an infection, but instead receives antibodies from outside sources. However, the action is quick because premade antibodies are administered.

‘Artificially induced immunity’ and ‘naturally induced immunity’ are two more categories into which these fit.

“Artificial active immunity” refers to immunity that is created by purposefully exposing a person to antigens in a vaccine (the term “artificial” comes from the fact that exposure did not occur naturally).

The endodermis, which has a cell membrane with a lower specific permeability than the other cells, is where the continuous flow domain of the cell-to-cell pathway is interrupted.

Your heart beats (contracts) due to electrical impulses coming from the heart muscle. At the top of the right atrium, the heart’s upper-right chamber, is the sinoatrial (SA) node, where this electrical signal starts. The heart’s “natural pacemaker” is the SA node. Electrical impulses are transmitted from the AV node, which is situated between the atria and the ventricles, to the point of the apex of the fascicular branches through the bundle of His, a group of heart muscle cells that are specialized for electrical conduction. One component of the heart’s electrical conduction system that regulates the upper chamber of the heart is the atrioventricular node, or AV node. It joins the ventricles and atria electrically.

Every day, about 30 liters of fluid flow from the blood capillaries into the interstitial space, while only 27 liters flow back into the blood capillaries from the interstitial fluid. The remaining three liters of fluid enter the lymphatic capillaries, where it is referred to as lymph, which means “clear spring water,” and then returns to the bloodstream via the lymphatic vessels.
