Urea is the body's principal vehicle for excreting unused nitrogen.
Nitrogen is an essential component of proteins and other biomolecules, and it is obtained from dietary sources.
When the body breaks down proteins for energy or other purposes, excess nitrogen is produced.
The liver converts this excess nitrogen into urea, which is then transported to the kidneys and excreted in the urine.
This process helps to maintain the balance of nitrogen in the body and prevent the buildup of toxic nitrogen-containing compounds.
Hydrogen, carbon, and oxygen are also important components of biomolecules, but they are not excreted as urea.
Instead, they are used in a variety of metabolic processes and are typically recycled or excreted in other forms, such as carbon dioxide and water.

i scream for ice cream lactase persistence in humans quizlet
Lactase persistence in humans refers to the ability to continue producing the enzyme lactase into adulthood, allowing individuals to digest lactose, the sugar found in milk and dairy products like ice cream.
Lactase persistence is a genetic trait that allows people to consume and tolerate lactose without experiencing symptoms of lactose intolerance. Historically, after infancy, many humans experienced a decrease in lactase production, which made the digestion of lactose difficult. However, lactase persistence has evolved in certain populations, primarily in areas where dairy farming and milk consumption were prevalent.
The ability to digest lactose in adulthood is most common in populations with a long history of dairy farming, such as populations in Northern Europe, parts of Africa, and some parts of South Asia. This lactase persistence trait is believed to have evolved due to the selective advantage provided by the ability to digest milk as a valuable food source.
The genetic variation associated with lactase persistence is most commonly found in the LCT gene, which codes for lactase production. Different variants of the LCT gene can determine the level of lactase production and the ability to digest lactose.
It's important to note that lactase persistence is not universal, and the ability to digest lactose varies among individuals and populations. Those who do not have lactase persistence can experience symptoms of lactose intolerance, such as bloating, gas, and diarrhea when consuming milk or dairy products like ice cream.

The tube that food travels in after it leaves the oral cavity is called the esophagus.
The esophagus is a muscular tube that connects the pharynx (the back of the throat) to the stomach.
It is responsible for moving food and liquids from the mouth to the stomach through a series of muscular contractions known as peristalsis.
Once food reaches the stomach, it is further broken down by stomach acid and digestive enzymes before being passed on to the small intestine for further digestion and absorption.
The esophagus is a muscular tube that connects the throat (pharynx) to the stomach. Its main function is to transport swallowed food and liquids from the mouth to the stomach for further digestion and absorption.
When food is swallowed, it passes through the esophagus via a series of coordinated muscular contractions called peristalsis. These contractions propel the food downward and help push it along the esophagus towards the stomach.
The esophagus has a sphincter called the lower esophageal sphincter (LES) located at the junction where it connects to the stomach. The LES opens to allow food to enter the stomach and then closes to prevent stomach acid from flowing back up into the esophagus, which can cause acid reflux or heartburn.

sleeping on one's stomach can reduce low-back pain
true or false
Answer:
False.
This is clearly false. It causes back pain.
False. Sleeping on one's stomach can actually increase low-back pain as it puts pressure on the spine and can lead to misalignment.
Here is a detailed explanation of how stomach sleeping can contribute to low-back pain:
1. Spinal Alignment: When you sleep on your stomach, your spine is forced into an unnatural position. The natural curvature of the spine, including the lordotic curve in the low back, is disrupted when you lie face down. This can lead to increased stress and strain on the muscles, ligaments, and joints of the lower back.
2. Increased Pressure: Stomach sleeping often involves turning the head to one side, which can further exacerbate the misalignment of the spine. Additionally, this position puts pressure on the vertebral discs in the lower back. The discs act as cushions between the vertebrae and are responsible for absorbing shock and providing stability. The pressure exerted on these discs when sleeping on the stomach can lead to compression and potential pain.
3. Hyperextension of the Neck: Stomach sleeping usually requires turning the head to one side to facilitate breathing. This position can result in hyperextension of the neck, where the head is tilted backward. Hyperextension can strain the muscles and ligaments in the neck and contribute to discomfort or pain in the cervical spine. Furthermore, this extended position of the neck can further disrupt the alignment of the entire spine.
4. Strained Muscles: Stomach sleeping can cause the muscles in the low back and neck to remain in a contracted and shortened position for an extended period. This can lead to muscle imbalances and tightness, causing discomfort and stiffness upon waking up.
5. Restricted Breathing: Sleeping face down can restrict the ability to breathe naturally, as the weight of the body puts pressure on the chest and abdomen. This can lead to shallow breathing, and in some cases, may result in a decrease in oxygen intake during sleep. Poor oxygenation can affect overall sleep quality and potentially contribute to musculoskeletal issues, including low-back pain.
In summary, sleeping on your stomach can increase low-back pain due to the pressure it puts on the spine and its potential to cause misalignment. By adopting alternative sleeping positions that promote better spinal alignment, you can reduce the risk of low-back pain and wake up feeling more refreshed and comfortable.
