RESPIRATORY
COPD- The airways and alveoli in lungs lose ability to stretch and shrink back. Walls between alveoli destroyed. Walls become inflamed and make excess mucus, clogging them and blocking air flow. Phlegm or dry Cough, frequent respiratory infections, short of breath, fatigue, chest pressure
Asthma- Airways inflamed, produce more mucus. Easier to inhale than to exhale. Cough at night, exercise, can be chronic, dry or with phlegm, difficulty breathing,, breathing through mouth, frequent respiratory
Spinal Cord Function and Neuron Types
Function of Spinal Cord:
It receives the information transmitted by the sensory organs. It interprets that information and prepares adequate responses. It transfers the necessary signals to the effector organs. It coordinates all the organs so that they function correctly in our body. It carries out intellectual and mental functions. It is responsible for our emotions and feelings.
Type of Neurons:
- Structure: Unipolar, multipolar, bipolar.
- Function: Sensory neurons (transmit info from the receptor to
Complement Pathways and Functions
Classical Pathway
Initiated when the complement component C1 recognizes a microbial surface directly or binds to antibodies bound to the surface of a pathogen. C1 is comprised of a recognition particle of C1q which is associated with the serine proteases C1r and C1s. C1r and C1s interact non-covalently forming C1r:C1s pairs, two or more of these pairs fold into the arms of C1q. C1q binds directly to the pathogen’s surface or Fc region of antibody bound to the microbial surface. The recognition function

UPSTREAM in bioprocess: STERILIZATION: It is used so only the biocatalyst grows. In the sterilization vapors are introduced through the equipment increasing the temperature. The sterilization cycle implies a rise in temperature, which is why the temperature drop must be taken into account. There are different levels of sterility: 1) Disinfection: destruction or removal of vegetative pathogens but not bacterial endospores. Usually used obly on inanimate objects. 2)Sterilization: complete removal
