why does our nose get stuffy when we have a cold
Answer:
Due to dilation of blood vessels in the sinuses of the nose
Explanation:
Often times, we think our nose gets stuffed up due to the excess mucus in times of cold but it is not always so.
We get stuffed due to the body's homeostasis, a drive to internally control and balance the outside environment.
- During cold, blood vessels dilate so as to allow for more inflow of blood.
- Incoming blood brings in more heat to the body parts.
Answer:
Adaptive immune responses are triggered by activation of antigen-specific T cells that produce antibodies against foreign antigens such as, for example, harmful viruses. These immune responses are useful to eliminate dangerous molecules from the body. In a normal immune reaction, the antibodies produced by T-cells target antigen molecules in order to be subsequently absorbed by phagocytic macrophage cells.
Autoimmune diseases are triggered by the response of the adaptive immune system against self-antigen molecules. Since the immune system can not eliminate antigens from the own body, this immune reaction generates an excessive inflammatory response, and it may lead to the damage of tissues and organs.
Oxygen is made and so is glucose (its actually sugar, but glucose is better sounding) by combining carbon dioxide and water using light energy as a source of energy. Also like to make sugars.
From the data of pH, the type <span>and relative size of the carbon-based molecules, you can relate these to determine at which levels that a certain carbon-based molecule. Hope this answers the question. Have a nice day. Feel free to ask more questions.</span>
