During acclimatization over a few days to weeks, the body produces more red blood cells to counteract the lower oxygen saturation in blood in high altitudes. Full adaptation to high altitude is achieved when the increase of red blood cells reaches a plateau and stops.Heart rate is controlled by the two branches of the autonomic (involuntary) nervous system. The sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS). ... At the beginning of exercise, your body removes the parasympathetic stimulation, which enables the heart rate to gradually increase.
D)all of them
Answer:
Explanation:
hepatic portal vein is a blood vessel that carries blood from the gastrointestinal tract and spleen to the liver. This blood are usually rich in nutrient because it contains extraction from digested materials or food substances in the gastrointestinal tract and it is processed in the liver for removal of toxins before the blood returns to the heart.
The small intestine absorbs most digested food molecules, as well as water and minerals, and passes them on to other parts of the body for storage or further chemical change. Specialized cells help absorbed materials cross the intestinal lining into the bloodstream.
True. Lipase is an enzyme that catalyzes the breakdown of lipids by hydrolyzing triglycerides. This is important for digestion and promoting absorption of fats in the intestines.
Lipase is a type of enzyme that breaks down fats, such as triglycerides, into glycerol and fatty acids. This process is essential for the proper digestion and absorption of fats in the intestines.
The breakdown of triglycerides begins with lipase. Lipase is produced by the pancreas and is secreted into the small intestine. Once it is secreted, it binds to the triglyceride molecules, breaking them down into glycerol and fatty acids. The glycerol and fatty acids are then absorbed into the bloodstream, where they can be used as energy or stored for future use
In conclusion, the statement that lipase is an enzyme that catalyzes the breakdown of lipids by hydrolyzing triglycerides is true. This is important for digestion and promoting absorption of fats in the intestines. Without the presence of lipase, fats would not be able to be broken down and properly absorbed. Therefore, it is essential for lipase to be present in order for the proper digestion and absorption of fats in the intestines.
