Lymphatic System

Leukocytes, also known as white blood cells, are responsible for protecting the body against infections and foreign invaders. They play a crucial role in the immune system by identifying and destroying pathogens such as bacteria, viruses, and other harmful substances. Leukocytes are produced in the bone marrow and circulate throughout the body in the blood.

A leukocyte esterase is an enzyme found in the urine that indicates the presence of white blood cells, specifically leukocytes. It is often used as a marker for urinary tract infections. High levels of leukocyte esterase can suggest inflammation or infection in the urinary tract.

Lymphocytes can live for weeks to years, depending on the specific type. B cells can live for a few days to several weeks, while memory T cells can persist for a lifetime. Factors such as the type of lymphocyte, presence of infections, and overall health can influence their lifespan.

When a protein is subcutaneously injected, it is the lymphatic system which will collect and remove that protein from the injected area. Therefore, the preferred method of delivering synthetic or naturally-formed proteins is a subcutaneous injection.

Yes, there are oil glands on the back. These glands, also known as sebaceous glands, produce sebum, an oily substance that helps keep the skin moisturized and protected. The distribution of these glands varies among individuals, with some people having more active oil glands on their backs than others.

M protein is a surface protein on Streptococcus pyogenes that can prevent phagocytes from recognizing and engulfing the bacteria. This evasion tactic allows the bacteria to evade the host immune response and persist in the body.

Neither! Protists are mainly simple organisms made of a single cell. They are small enough to obtain their oxygen and remove wastes by diffusion. Diffusion is also rapid enough to distribute substances inside the cell. Therefore a circulatory system is not needed. No a fucn circulkatory sdmaskjofnmdsijp fadsm [fas fcds

However Fungi are not protists.

Activated Tc cells can differentiate into both cytotoxic T-lymphocytes, which directly kill infected or cancerous cells, and memory T cells, which are long-lived and provide a rapid response upon re-exposure to the same pathogen. This differentiation allows the immune system to mount a faster and more efficient response upon encountering the same threat in the future.

Cell division plays a crucial role in growth, development, and repair of an organism by allowing for the formation of new cells to increase the size of the organism, replace damaged or old cells, and facilitate tissue regeneration. During growth and development, cell division is essential for increasing the number of cells and shaping the structure of tissues and organs. In the repair process, cell division helps replace damaged cells and tissues with new healthy ones.

The three main functions of the lymphatic system are fluid balance, immune defense, and lipid absorption. It helps to maintain fluid balance in the body by draining excess fluid from tissues, supports the immune system by producing and transporting white blood cells, and absorbs fats and fat-soluble vitamins from the digestive system.

Interstitial fluid (or tissue fluid) is a solution that surrounds the cells of animals. It is the main component of the extracellular fluid, it includes plasma and transcellular fluid. The interstitial fluid is found in the interstitial spaces, also known as the tissue spaces.

The fatty layer in the integumentary system, known as the subcutaneous layer or hypodermis, serves various functions. It acts as an insulator to regulate body temperature, stores energy in the form of fat, provides cushioning and protection for underlying tissues and organs, and helps in the attachment of the skin to the underlying muscles and bones.

What are the organs of the immune system?

Our immune system is made up of both individual cells and entire organs and organ systems which fight against foreign infection from harming our bodies

Starting from Organs that function as barriers Your skin and mucous membranes are the first line of defense against germs entering from outside the body. ** 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.

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, reason why you need to strengthen your immune system with healthy food and supplements like these (linktr.ee/HealthyAid ) to help strengthen the immune system.

Thymus 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.

Secondary lymphoid organs: These organs include the lymph nodes, the spleen, the tonsils and certain tissue in various mucous membrane layers in the body

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.

Spleen It stores various immune system cells. When needed, they move through the blood to other organs. 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. ** Tonsils** The tonsils are also part of the immune system. Because of their location at the throat and palate, they can stop germs entering the body through the mouth or the nose. The tonsils also contain a lot of white blood cells, which are responsible for killing germs.

Mucous membranes

The bowel plays a central role in defending the body against germs: More than half of all the body's cells that produce antibodies are found in the bowel wall, especially in the last part of the small bowel and in the appendix. These cells detect foreign substances, and then mark and destroy them. They also save information about the substances in order to be able to react more quickly the next time. The large bowel also contains harmless bacteria called gastrointestinal or gut flora. Healthy gut flora make it difficult for germs to spread and enter the body.

Mucous membranes support the immune system in the body, The immune system cells are directly beneath the mucous membranes, where they prevent bacteria and viruses from attaching

The eight organs of the immune system are the tonsils, thymus, bone marrow, spleen, lymph nodes, adenoids, appendix, and Peyer's patches in the small intestine. These organs play crucial roles in the immune response, such as producing and storing immune cells, filtering pathogens from the bloodstream, and coordinating immune responses.

White blood cells

The lymph nodes trap the white cells (bacteriophages) coming in from the periphery of the body.

The medical term for the removal of a mediastinal organ is mediastinal organ resection. This procedure involves the surgical removal or partial removal of an organ located in the mediastinum, the central compartment of the chest cavity. It is typically performed to treat conditions such as tumors or infections affecting organs in this region.

Sebum, an oily substance produced by the sebaceous glands in the skin, can help protect the skin and hair follicles from harmful microbes. It has antimicrobial properties that can help fight off bacteria and fungi, thus supporting the immune system's defense against infections.

The inguinal nodes are located in the groin area, near the crease between the thigh and the lower abdomen. These nodes play a role in filtering lymphatic fluid from the lower extremities, genitals, and pelvic region.

The organ you are referring to is the spleen. It plays a crucial role in filtering and recycling old and damaged blood cells, as well as producing new blood cells in times of need. The spleen also stores extra blood cells that can be released into circulation when necessary.

Based on these percentages alone, it is not possible to determine if someone has HIV/AIDS. Diagnosis of HIV/AIDS requires specific laboratory tests to detect the presence of the virus. It is recommended to consult a healthcare professional for further evaluation and testing.

A lymph blood test is used to measure the levels of lymphocytes, a type of white blood cell, in the bloodstream. This test helps in evaluating the immune system's function and can be used to diagnose infections, autoimmune disorders, and certain types of cancer.

Smoking affects your immune system because when you smoke, not enough oxygen is able to enter your lungs, which can lead to lung cancer; lung cancer eventually leads to death If not cared for properly. Smoking also kills enzymes and causes your immune system to weaken & when the res blood cells are in need of nourishment, [white blood cells were killed for smoking too much] there are no WBC's to aid them.

Lymph nodes are located throughout the entire body, linked by the lymphatic vessels.
