Hi
It is true that the point of entry of a pathogen inside a body hold importance for the spread of pathogen. However, <em>organ and tissue specific manifestation is the real impact of a pathogen in any organism's body. Firstly we need to understand what is meant by Organ and tissue specific manifestation:</em>
It means that the specific organ or specific tissue is when affected by the entry of microbes or pathogens in the body, For example: The bacteria that cause tuberculosis enters the body through nose but manifests its action in lungs when multiplies there and affects the lungs' functionality and ultimately, depict the symptoms such as shortness and difficulty of breathing, this is basically organ specific manifestation.
Moreover, thee are some microbes that enter the body and damage certain tissues, for example HIV virus enters the body through sexual organs and travels to different tissues like nerve tissues, lymphatic system and damage them in a way that body's own immune system when counter reacts the microbes, it causes inflammation in the body and damage to overall tissues, This is called Tissue specific manifestation.
Hope it helps!
Answer:
Exocytosis: It is defined as the process of membrane-bound vesicles fusing with the plasma membrane and later releasing their contents to the extracellular part of the cell.
Endocytosis: It is defined as the process of capturing a particle from outside the cell by the engulfing process with the cell membrane. It is basically two types:
1) Pinocytosis: Cellular drinking.
2) Phagocytosis: Cellular eating.
There are many internal factors which living organisms respond to, two of them are temperature and hormone levels. Organisms respond to internal factors in order to stay healthy and survive. The internal environment of living organisms has to be kept relatively constant, this is constancy is achieved through the process of homeostasis.
Answer:
Gases, liquids and solids are all made up of atoms, molecules, and/or ions, but the behaviors of these particles differ in the three phases.
Explanation:
gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.
Answer: Ligand gated channel
Explanation:
Ligand gated channel is an essential membrane protein that has pores and allows the passage of specific ions across the plasma membrane when it is activated by a specific chemical . Examples of such ions that pass through Ligand gated channels are Sodium ions, Potassium ions, Calcium ions. Ligand gated channels are found in extensions of the nerve cells.
