Valves are like flaps or lids that are used to transport blood from the atria to the ventricles. They act as inlets and outlets of blood.
Explanation:
The atrioventricular valves are located Left and right that are in the middle of atria and ventricle on both sides of the heart while two semilunar valves separate the right and left ventricles from the pulmonary valve and aortic valve.
The Atrioventricular valves are the mitral valve and the tricuspid valve. Mitral valve is in the left side and tricuspid valve is in the right. they both are separated by the atrium and ventricle
The two semilunar valves are the pulmonary valve and aortic valve. the pulmonary valve is on the right side separated by the right ventricle and pulmonary artery. The aortic valve is on the left and is separated by the left ventricle and aorta.
Answer:
The correct answer is the duodenum.
Explanation:
Pancreatic juice is an alkaline fluid which contains important enzymes for the digestion of proteins, carbohydrates and fats.
Pancreatic juice is secreted by the pancreas when food enters the stomach which is released into the "duodenum" of the small intestine. The pancreatic juice enters duodenum through a pancreatic duct which joins with the bile duct coming from the liver and form "ampulla of Vater" in the duodenum.
Pancreatic juice helps in digestion of carbohydrates, proteins and fats as it contains pro-enzymes and enzymes like trypsinogen, chymotrypsinogen, lipase and many more. It also makes the acidic stomach solution alkaline due to the presence of HCO₃.
Thus, the duodenum is the correct answer.
Answer:
Small branches may be damaged at 25° to 29°F, and large branches and mature trees may be killed at temperatures of 20° to 24°F. Symptoms of freezing damage include leaf wilting, water soaking, desiccation, and drop; stem and limb dieback; fruit drop; and tree death.
