Pulmonary Circulation: It's All in the LungsPulmonary circulation is the movement of blood from the heart, to the lungs, and back to the heart again. This is just one phase of the overall circulatory system.The veins bring waste-rich blood back to the heart, entering the right atrium throughout two large veins called vena cavae. The right atrium fills with the waste-rich blood and then contracts, pushing the blood through a one-way valve into the right ventricle. The right ventricle fills and then contracts, pushing the blood into the pulmonary artery which leads to the lungs. In the lung capillaries, the exchange of carbon dioxide and oxygen takes place. The fresh, oxygen-rich blood enters the pulmonary veins and then returns to the heart, re-entering through the left atrium. The oxygen-rich blood then passes through a one-way valve into the left ventricle where it will exit the heart through the main artery, called the aorta. The left ventricle's contraction forces the blood into the aorta and the blood begins its journey throughout the body.
The one-way valves are important for preventing any backward flow of blood. The circulatory system is a network of one-way streets. If blood started flowing the wrong way, the blood gases (oxygen and carbon dioxide) might mix, causing a serious threat to your body.
You can use a stethoscope to hear pulmonary circulation. The two sounds you hear, "lub" and "dub," are the ventricles contracting and the valves closing.
What else can I help you with?
If you wanted to find the glands that produce salivary amylase where would you look?
You would look for the salivary glands, including the parotid, submandibular, and sublingual glands, which produce salivary amylase. These glands are located in and around the mouth and release saliva containing the enzyme salivary amylase to help break down carbohydrates in the mouth.
How is salivary amylase active in the stomach?
Amylase is not active in the stomach, the environment is too acidic. This is why the pancrease produces and secretes amylase into the duodenum after food leaves the stomach, to replace the amylase secreted by salivary glands and denatured by stomach acid.
What might happen if salivary amylase was not present or didn't work properly?
If salivary amylase was not present or didn't work properly, it would impede the breakdown of starches in the mouth, making it harder for the body to digest carbohydrates. This could lead to poor nutrient absorption and possibly result in digestive issues like bloating and discomfort.
What substrate would fit into the active site of amylase?
Starch would fit into the active site of amylase. Amylase is an enzyme that catalyzes the hydrolysis of starch into smaller sugar molecules such as maltose. The active site of amylase has a specific shape that allows it to bind to the starch substrate and break it down into simpler sugars.
What temperature does amylase work best at?
Amylase works best at body temperature, which is around 37 degrees Celsius. This is because if the temperatre is too low, the amylase will collide slow as the kinetic energy will be low. It reacts fastest and best in this temperatue as lota of kinetic energy is given to the molecules and the particles therefore collide faster. Although, when the temperature is too high, the enzymes (amylase) gets denatured which means that they loose their shape. This way they do not react.
If you wanted to find the glands that produce salivary amylase where would you look?
You would look for the salivary glands, including the parotid, submandibular, and sublingual glands, which produce salivary amylase. These glands are located in and around the mouth and release saliva containing the enzyme salivary amylase to help break down carbohydrates in the mouth.
How does the effect of freezing differ from the effect of boiling in salivary amylase and cellulose?
Freezing would denature salivary amylase by disrupting its molecular structure, rendering it inactive. However, boiling would also denature salivary amylase but much more rapidly and completely. Cellulose is not affected by freezing but boiling can break down its rigid structure, making it more digestible.
A mutation in the genes for salivary amylase will greatly affect the chemical digestion of what?
Amylase is responsible for the digestion of starches in the body. If a mutation occurred in the genes coding for the production of amylase, this would interfere with the body's ability to digest starches and other complex carbohydrates (which begins in the mouth with enzymes from the salivary glands).
After a meal of greasy french fries which enzymes would you expect to be most active?
salivary and pancreatic amylase, dissaccharideases, lipase
How is salivary amylase active in the stomach?
Amylase is not active in the stomach, the environment is too acidic. This is why the pancrease produces and secretes amylase into the duodenum after food leaves the stomach, to replace the amylase secreted by salivary glands and denatured by stomach acid.

If salivary amylase was not present or didn't work properly, it would impede the breakdown of starches in the mouth, making it harder for the body to digest carbohydrates. This could lead to poor nutrient absorption and possibly result in digestive issues like bloating and discomfort.
What is the kind of enzyme?
Enzymes are chemicals that accelerate chemical processes. They are like a catalyst where they do not participate in the reaction itself; they just make it happen more quickly. Enzymes can usually be found in the digestive system. An example would be salivary amylase.
Which enzyme will help you hydrolyze polymers into disaccharides or monomers after eating carbohydrates?
The most common enzyme would be salivary/pancreatic amylase which hydrolyzes the polysaccharide amylose.
Would amylase be active in the stomach?
Salivary amylase works well around pH 7 (inside the mouth), but inside the stomach are gastric juices which contain HCl. Since the HCl drops the pH of the solution significantly, it denatures the amylase so that it will no longer function as it normally would, breaking down starch and glycogen.
Can hemorrhoids cause high amylase levels?
Hemorrhoids themselves do not typically cause high amylase levels. Elevated amylase is usually associated with conditions affecting the pancreas, such as pancreatitis, or issues with the salivary glands. If someone has both hemorrhoids and high amylase levels, it is likely that the two are unrelated, and further investigation would be needed to determine the cause of the elevated amylase. Consulting a healthcare professional is advisable for accurate diagnosis and treatment.
