An essential component of the immune system are lymphocytes. The majority of lymphocytes are found in the thymus, spleen, bone marrow, and lymph nodes. Option D is therefore accurate.

Monocytes are a subset of white blood cells that only live for ten to twenty hours. After being created in the bone marrow, they briefly circulate in the blood before settling in tissues and developing into macrophages. Macrophages contribute to the immune response and are in charge of clearing away debris and dead cells.

Atherosclerosis is a condition brought on by elevated blood cholesterol levels. Cells like lymphocytes, neutrophils, eosinophils, basophils, and phagocytes like macrophages make up the immune system. Additionally, it contains complement proteins that aid in the fight against the incoming pathogen. Released cytokines encourage inflammation, an immunological reaction to the infection.

Because it has three flaps, the valve that sits between the right atrium and the right ventricle is called the tricuspid valve.

The heart receives blood from every vein.

Option A is the right one since Carbonic anhydrase, an enzyme found in red blood cells, helps transform carbon dioxide into bicarbonate ions and carbonic acid.

(c) The upper region of the right atrium of the heart contains a specialized bundle of neurons called the SA (sinoatrial) node. The natural cardiac pacemaker that causes the heartbeat is called the SA node. Damage to this system could cause the heart chambers to receive ill-coordinated impulses, which could lead to symptoms like fatigue, lightheadedness, loss of consciousness, and an irregular heartbeat. An artificial pacemaker is implanted at the location of the SA node to replicate the node’s and conducting system’s functions and aid in heartbeat regulation because the pacemaker cells produce this rhythmic impulse.

“Xylem” is the response.
Justification: Phloem is typically located on the outside of xylem, which is in charge of carrying minerals and water in plants.
