What do aquatic arthropods exchange gases through?
Aquatic arthropods typically exchange gases through gills. Gills are structures that are rich in blood vessels and provide a large surface area for gas exchange to occur, allowing the arthropods to extract oxygen from the water and release carbon dioxide.
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
What is the effect of histamine on small as well as large blood vessels?
Histamine causes the dilation of the small blood vessels while constrict the large blood vessels.
How does the tiny flaps covered with blood vessels in the gills of the fish help it to survive?
The tiny flaps, or filaments, in the gills of fish are rich in blood vessels and play a crucial role in respiration. They facilitate the exchange of oxygen and carbon dioxide between the water and the fish's bloodstream, allowing fish to efficiently extract oxygen from the water as it flows over the gills. This adaptation is essential for survival, especially in aquatic environments where oxygen levels can fluctuate. Additionally, the large surface area provided by the filaments enhances this gas exchange, supporting the metabolic needs of the fish.
Why is it important that the gills of a crayfish give them a large surface area?
It is important that the gills of a crayfish give them a large surface area because it helps the crayfish to breathe. The bigger the surface area, the more oxygen in the crayfishes system.Ê
What is the large peripheral blood vessels into which extra-embryonic blood vessels open?
vitilline vein
What blood vessel has bigger activities?
Blood vessels are structures that carry the blood from the heart to all the tissues of the body and then back to the heart.arteries: large blood vessels running away from the heartveins: large blood vessels running toward the heart
What makes villi good at absorbing food?
large surface area, thin epithelium, highly profused with blood vessels and lymphatics
Which feature is common to gills lungs and tracheae?
Large surface area
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.
