where do immune cells monitor for the presence of pathogens that invade the interstitial space?

Answers

Answer 1

Immune cells monitor for the presence of pathogens that invade the interstitial space in the lymph nodes.

Lymph nodes are small, bean-shaped structures that are distributed throughout the body along the lymphatic vessels. They are part of the lymphatic system, which is a network of vessels and tissues that help maintain fluid balance in the body and defend against infection.

The lymph nodes act as filters for the lymphatic fluid, which contains immune cells, debris, and pathogens that have entered the interstitial space from the surrounding tissues.

When a pathogen enters the interstitial space, it is engulfed by immune cells called antigen-presenting cells (APCs), such as dendritic cells and macrophages. The APCs then transport the pathogen to nearby lymph nodes, where they present it to other immune cells, such as T cells and B cells. This process, known as antigen presentation, triggers an immune response that can lead to the elimination of the pathogen.

Therefore, lymph nodes serve as the site of immune cell activation and coordination in response to pathogens that have invaded the interstitial space.

how are viroids different from viruses​

Answers

Answer:

We are all familiar with the basics of viruses: These particles infect living cells and wreak havoc throughout the body. But viruses aren’t the only villains around causing chaos in living things. Other infectious agents called viroids and prions — which are also tiny but powerful — can take down both plant life and entire animals.

Viroids are free RNA molecules of low molecular weight without any protein coat, while viruses can have either RNA or DNA molecules encapsulated in a protein coat. Viroids are smaller in size than viruses.

Viroids not made of cells.

Viroids don’t transform energy.

Viroids can’t reproduce on their own.

Answers

D, because they are not heavy, so if they form 20 percent of the mass of all land animals combined it means that there are many ants in the world due to the fast breed

Ant breed faster than any other organism on earth, 20% of earth mass have land animals. Many ants are on the earth. Thus, option D is correct.

Explain the mechanism of ventilation in human lungs (you should talk about the diaphragm, abdominal muscles and rib cage and intercostal muscles)

Answers

Answer: When the diaphragm contracts, it moves inferiorly toward the abdominal cavity, creating a larger thoracic cavity and more space for the lungs. Contraction of the external intercostal muscles moves the ribs upward and outward, causing the rib cage to expand, which increases the volume of the thoracic cavity.

The movement of diaphragm and ribs govern the mechanism of ventilation in human lungs.

The ventilation in human lungs or pulmonary ventilation is defined as the process of intake of air during inhalation, and expiration as the release out of air. It is also termed as breathing.

What is the mechanism of pulmonary ventilation?

The lungs are present in the thoracic cavity, with the diaphragm below the lungs separating the thoracic cavity from the abdominal cavity. The rib cage is present outside lungs and prevent them.

Inhalation process in pulmonary ventilation

The inhalation is the process of taking in air. The increase in the volume of lungs results in the increased movement of diaphragm to the abdominal cavity.

The intercostal muscles move upwards and the rib cage move outwards. Thus, the air is inhaled in the system.

Exhalation process in pulmonary ventilation

The exhalation of air is performed antagonist to the inhalation. The relaxation of diaphragm and the movement of rib cage results in the decreased volume of the lungs, and the air is expelled.

Thus, the movement of diaphragm and ribs govern the mechanism of ventilation in human lungs.

How do you think about the invention of the microscope? Influenced the cell theory?
And what are the components of the cell theory?

Answers

Answer:

See the answer below

Explanation:

The invention of the microscope paved way for the development of the cell theory because, without it, the cell and all the organelles of the cell would not have been discovered and or studied in great detail. It was through the use of  a microscope that Robert Hooke was able to observe and name the cell and it was through the same microscope that the fine details of the cell were able to be studied by other scientists, culminating in the formulation of the cell theory.

The cell theory states that all living organisms are made up of cells, the cell is the basic unit of all life, and cells can only arise from already existing cells (via cell division). The components of the cell theory, therefore, are:

Living organisms are made up of cells.The cell represents the basic unit of life.Cells can only arise from preexsiting cells.
