Why do gills have a large surface area and are rich in blood?
because in many organisms like fish etc it is an organ for respiration the gills are supplied with capillaries so that the oxygen absorbed can diffuse into the blood it has large surface area so that more oxygen can be diffused in and more co2 can be removed
Why is the feathery nature of gills gives them a very large surface area is important?
Without the large surface are, the gills would have to be much larger and that may have prevented the development of the organisms that use gills.
What is the effect of histamine on small as well as large blood vessels?

The feathery nature of the gills gives the crayfish a very large surface area why is this important?
To acquire more oxygen from water as the large SA of the gills allow more water to pass through and thus more O2 from the water to transfer into the gill-bearing creature's bloodstream for respiration
What is the blood that supplies the blood vessels?
small blood vessels called Vaso Vasorum these are for large arteries others by diffusion
How do gills extract oxygen from H2o?
Whale shark gills are similar in structure to other fish gills. Oxygenated water is passed over the gills which have a rich, near surface blood supply and gases are exchanged between the blood and the water. The gills are feathery and have a large surface area so that there is enough gas exchange to keep the fish supplied with the oxygen it needs.
What are the vessels involved in supplying and draining blood from the small and large intestines?
The blood vessels that are involved for supplying and draining blood from the small intestine are called the superior mesenteric. The blood vessels that supply and drain the large intestines are called the inferior mesenteric.
