Answer:
All the arteries except pulmonary artery carry pure blood..it is so because blood flows with a high pressure and speed And because Arteries are situated deeper under the skin have thick-walled with Narrow lumen(cavity) and pulmonary artery carries deoxygenated blood i.e without oxygen..
Explanation:
lumen means Empty space within an object(solid)

Answer:
Inflammation
Explanation:
Inflammation is an immune response produced in the body in response to the damage or trauma caused by physical or chemical factors.
The injured tissue can allow the entry of the microorganism in the body which could cause disease therefore the immune response gets activated to eliminate the pathogen.
The inflammation is marked by the swelling and redness in the injured portion due to the increased flow of blood carrying the White blood cells in that area. The immune cells interact with the pathogen and kill the pathogen.
Thus, Inflammation is the correct answer.
Answer:
here is ur answer
Explanation:
The control group is defined as the group in an experiment or study that does not receive treatment by the researchers and is then used as a benchmark to measure how the other tested subjects do.
Answer:
A diploblast has no mesoderm.
A pseudocoelom has the same functions as a true coelom. In a coelomate, the tissue lining the inner side of the body cavity arises from the same germ layer as the tissue lining the outer side of the body cavity.
Explanation:
Diploblast organisms are the ones that have only two primary germ layers. These organisms have outer ectoderm and inner endoderm but no mesoderm. Example: Cnidarians
A true coelom is derived from mesoderm and is completely lined with tissue derived from mesoderm. The outer and inner linings of the coelom are made of muscle layers that are developed from the mesoderm.
A pseudocoelom is the one that is incompletely lined with mesoderm. Both pseudocoelom and a true coelom serve as shock absorber and provide space wherein the internal organs can be placed. The fluid present in them sere as medium for transport of nutrients, gases, etc.
