I believe, for the artery, they have, an open, circular lumen an a thick media
Veins on the other hand, have somewhat collapsed lumen and a thinner media. Arteries are blood vessels that carry blood out of the heart to other parts of the body, all arteries carry oxygenated blood except the pulmonary artery which carries deoxygenated blood from the heart to the lungs. Veins carry blood from other body parts to the heart, all veins carry deoxygenated blood except the pulmonary vein which caries oxygenated blood from the lungs to the heart.

Salts and sugars work to preserve foods by creating a
Ne4ueva [31]

Answer: Hypertonic Environment

Explanation:

The salt solution and sugar solution is used for the process of food preservation as the bacteria and microorganism are not able to grow in such conditions that is being created by the solution.

The amount of the solute is more and the solution is less concentrated. The bacteria cell has less solutes and more solvent.

As per osmosis the water from the salt or sugar solution moves out from bacterial cell shrinks and dies.

This is how the bacterial cell dies and the food is prevented from spoilage.

adelina 88 [10]

Answer:

Haemoglobin; liver; binds; stored; bile duct; small intestine; lipids.

Explanation:

Serology can be defined as the study of blood and the reactions between antibodies and antigens in the blood.

In Biology, blood pH can be defined as a measure of the hydrogen ion (H¯) concentration of blood i.e the level of alkalinity or acidity of blood.

Basically, the normal blood pH of a human being should be between 7.35 and 7.45.

Hence, one of the ways in which the body regulates blood pH is with proteins. Proteins help regulate blood pH by accepting and releasing hydrogen ions. Typically, when the blood pH falls, the hydrogen ions (H¯) are accepted (absorbed) while hydrogen ions are released when the blood pH rises.

For example, a protein such as haemoglobin which makes up a composition of the red blood cells, binds an amount of acid required to regulate blood pH.

In the spleen, haemoglobin from red blood cells is broken down to form (unconjugated) bilirubin. Unconjugated bilirubin is insoluble in blood plasma so binds to albumens in the blood and is sent to the liver. Bilirubin binds with glucuronic acid to form conjugated bilirubin. It forms part of the bile, which is stored in the gall bladder. Food in the gut stimulates gall bladder contraction and the bile passes down the bile duct to the small intestine, where it aids in the digestion of lipids.
