-rapid
-produces a direct result
-drugs are absorbed directly into the bloodstream
Answer:
There are about 4 types of blood which are
Explanation:
A, B, AB and O, but all these can be positive and negative making it 8 blood types
Fun Fact: O negative blood is the rarest, meaning you can share it with anyone (donate).
Answer: Process, Tubercle, Condyle
Explanation:
Possible assortment of the influenza genome with swine and human strains
What is human h5n1 infections?
influenza virus strains that primarily affect birds but can also infect people.
The most common way to catch this disease is through contact with sick birds. Additionally, it can be spread from person to person.
Within two to eight days, symptoms start to appear, and they may resemble the common cold. Shortness of breath, muscle aches, headaches, fever, sore throat, and cough are possible symptoms.
In humans, the sickness may result in a high fatality rate. If administered within two days of symptoms, several antiviral medications may be helpful.
Types A, B, C, and D are the four different types of influenza viruses.
- Humans and a variety of animals are both susceptible to influenza A viruses.
- An influenza pandemic could be brought on by the appearance of a brand-new, radically different influenza A virus with the capacity to infect people and maintain sustained human-to-human transmission.
- Humans are exposed to influenza B viruses, which spread and lead to seasonal epidemics.
- Seals can contract infections, according to recent evidence.
- Both people and pigs can contract influenza C viruses, but illnesses are typically mild and hardly documented.
- Influenza D viruses are known to primarily infect cattle; they are not known to infect or afflict humans.
Hence, Possible assortment of the influenza genome with swine and human strains

Answer:
Kupffer cells, also known as stellate macrophages due to their particular structure while viewed under a microscope, were first identified by scientist Karl Wilhelm von Kupffer, after whom the cells were named, in 1876.
These cells, whose origin is in the yolk sack during fetal development, later on move to the liver where they will stay and further differentiate into their mature versions.
These cells are part of the liver cells, and are found particularly on the walls of the sinusoids, where they perform their two most important tasks. First, these cells are part of the immune system, as they are essentially macrophages. However, their role is pretty unique, as they are responsible not just for phagocytosis of invading bacteria, and other pathogens, and initiating immune responses, but also, this cell plays a role in decomposing red blood cells who are dying, and taking up the hemoglobin from them to further break that into reusable globin, and the heme group, from which iron is further extracted to be re-used and also to create bilirrubin, a part of bile.
Finally, these cells have been found to be connected to hepatic cirrhosis, as in their process of detoxifying ethanol, they produce toxins that force the liver cells to produce collagen, and thus to become fibrous.
