What are the organs of the immune system?

Publication Details

Our immune system is made up of both individual cells and proteins as well as entire organs and organ systems. The organs of the immune system include skin and mucous membranes, and the organs of the lymphatic system too.

Organs that function as barriers

Your skin and mucous membranes are the first line of defense against germs entering from outside the body. They act as a physical barrier with support from the following:

Antibacterial substances can kill germs right from the start. A certain enzyme found in saliva, the airways and tear fluid destroys the cell walls of bacteria.

Mucus in the bronchi helps trap many of the germs we breathe in so they can be moved out of the airways by hair-like structures called cilia.

Stomach acid stops most of the germs that enter the body in the food we eat.

Harmless bacteria on our skin and many of the mucous membranes in our body also act as part of the immune system.

In addition, the reflexes that cause us to cough and sneeze help to free our airways of germs.

The parts of the immune system

Lymphoid organs

The lymphatic system is composed of:

Primary lymphoid organs: These organs include the bone marrow and the thymus. They create special immune system cells called lymphocytes.

Secondary lymphoid organs: These organs include the lymph nodes, the spleen, the tonsils and certain tissue in various mucous membrane layers in the body (for instance in the bowel). It is in these organs where the cells of the immune system do their actual job of fighting off germs and foreign substances.

Bone marrow

Bone marrow is a sponge-like tissue found inside the bones. That is where most immune system cells are produced and then also multiply. These cells move to other organs and tissues through the blood. At birth, many bones contain red bone marrow, which actively creates immune system cells. Over the course of our life, more and more red bone marrow turns into fatty tissue. In adulthood, only a few of our bones still contain red bone marrow, including the ribs, breastbone and the pelvis.

Thymus

The thymus is located behind the breastbone above the heart. This gland-like organ reaches full maturity only in children, and is then slowly transformed to fatty tissue. Special types of immune system cells called thymus cell lymphocytes (T cells) mature in the thymus. Among other tasks, these cells coordinate the processes of the innate and adaptive immune systems. T cells move through the body and constantly monitor the surfaces of all cells for changes.

Lymph nodes

Lymph nodes are small bean-shaped tissues found along the lymphatic vessels. The lymph nodes act as filters. Various immune system cells trap germs in the lymph nodes and activate the creation of special antibodies in the blood. Swollen or painful lymph nodes are a sign that the immune system is active, for example to fight an infection.

Spleen

The spleen is located in the left upper abdomen, beneath the diaphragm, and is responsible for different kinds of jobs:

It stores various immune system cells. When needed, they move through the blood to other organs. Scavenger cells (phagocytes) in the spleen act as a filter for germs that get into the bloodstream.

It breaks down red blood cells (erythrocytes).

It stores and breaks down platelets (thrombocytes), which are responsible for the clotting of blood, among other things.

There is always a lot of blood flowing through the spleen tissue. At the same time this tissue is very soft. In the event of severe injury, for example in an accident, the spleen may rupture easily. Surgery is then usually necessary because otherwise there is a danger of bleeding to death. If the spleen needs to be removed completely, other immune system organs can carry out its roles.

Answer:

B. Blood in the left ventricle is deoxygenated.

Explanation:

Human heart consists of four chambers namely: right atrium, right ventricle, left atrium and left ventricle. These chambers work hand in hand to perform the function of circulating blood throughout the body.

- The RIGHT ATRIUM receives deoxygenated blood from the heart and passes it to the RIGHT VENTRICLE, which pumps it to the lungs in order to be oxygenated.

- The LEFT ATRIUM receives oxygenated blood from the lungs and passes it to the LEFT VENTRICLE, which pumps it into the body.

- Also, the pulmonary artery carries deoxygenated blood into the lungs for oxygenation while the pulmonary veins carry oxygenated blood from the lungs

Based on the above explanation of the right & left atria and the right & left ventricles, it is FALSE that the blood in the left ventricle is deoxygenated. It is rather oxygenated.

RNA interference is a mechanism of eukaryotic gene regulation. In this mechanism, the enzyme “dicer” cuts dsRNA into smaller fragments called siRNA, which form a complex with RISC and degrade specific RNA.

siRNA or small interfering RNA as a part of RISC complex finds and binds to complementary mRNA and it induces the cleavage of mRNA. This causes degradation of that mRNA. This is the way RNA interference prevents translation.

Answer:

B. the two strands of DNA are antiparallel, and DNA polymerase can only add new nucleotides onto a 5' end

Explanation:

Deoxyribonucleic acid, known as DNA, is the genetic material of a cell, which must first undergo replication i.e produce two identical copies of itself, before a cell can divide. During replication, the double stranded DNA unwinds into a replication fork consisting of two single strands of DNA.

These single strands of DNA are called leading strand (runs from 3'-5') and lagging strand (runs from 5'-3'). These single strands that runs at opposite direction from one another exists at the replication fork because the two strands of DNA are antiparallel i.e. are opposite to one another, and DNA polymerase can only add new nucleotides onto a 5' end.

Leading and lagging DNA strands exist at a replication fork because the two strands of DNA are antiparallel, and DNA polymerase can only add new nucleotides onto a 5 'end.

A replication fork is the juncture between two strands of DNA when it is replicating itself.

In each of them (speaking of the homologous strands) the opposite chain is carried out to have the double genetic information when approaching cell division.

Therefore, we can conclude that leading and lagging DNA strands exist at a replication fork because the two strands of DNA are antiparallel, and DNA polymerase can only add new nucleotides onto a 5 'end.

Somewhere in the Fourteen-ish and Eighteen-ish, that's just my opinion of this matter.

Eighteen is the perfect age does a person to begin to think about education and career goals over relationships with friends.

Being an adult means being responsible for yourself. So instead of doing everything you want to do, you start to compromise. You learned that you need to take care of your problems instead of running away from them. Instead of pulling out an all-nighter, you learn to manage your time better.

After the eighteenth of a person, a person should be considered an adult. Adulthood is a stage where a person considers themselves more responsible for their lives and carrier goals.

Explanation:

The idea that the brain of an infant is like a blank slate is known as Tabula rasa. It is given in Locke's philosophy. Thus, the correct option is A.

Tabula rasa is the theory which describes that individuals are born without a built-in mental content, and therefore all the knowledge comes from experience or perception in life. The epistemological proponents of the tabula rasa disagree with the doctrine of innatism, that holds the fact that the mind is born already in possession of certain knowledge eithout experience.

In Locke's philosophy, tabula rasa was the theory that at birth the infant mind is a blank slate without rules for processing data, and the data is added and rules for processing are formed solely by one's sensory experiences in life.

Therefore, the correct option is A.

All of Earth's biomes considered together represent biosphere.

A biome is an amalgamation of plants and animals with similar traits for their habitat. Biomes can be found in many different locations. They are biological communities that have developed as a result of the area's common physical climate.

The biosphere is a small area of the earth's surface where soil, water, and air work together to support life. Only in this region is life possible.

A population is a collection of people who can interbreed, share resources, or compete with one another for those resources.

A community is defined as a collection of individuals belonging to various species who reside in the same region.

An ecosystem is a biotic and abiotic component-based functioning unit of nature. Air, water, and soil are examples of abiotic components. The biotic components are producers, consumers, and decomposers.
