Those amounts are equivalent to about 2 cups of air in a single breath. Since the average person at rest breathes about 12 times per minute, with a tidal volume of a half liter per breath, that equates to a rate of about 6 ...
How many liters of blood filter by our kidneys per day? What is the percentage of plasma in the total blood volume in human beings? What is the pH value of Human blood? How much blood does a person have in their body? How much do they have to lose for it to be fatal? Choose t...
In contrast, a cigarette delivers about 23 nanograms per milliliter of nicotine in the first five minutes, but by 30 minutes the levels of nicotine in the body are comparable between the two products [source: Gartner et al.]. To substitute for the flavor that's lost in the pasteurization ...
The ratio of breath alcohol concentration to blood alcohol content is 2,100:1. This means that 2,100 milliliters (ml) of alveolar air will contain the same amount of alcohol as 1 ml of blood. For many years, the legal standard for drunkenness across the United States was 0.10, but ...
The average human being inhales and exhales a total of 11,000 liters of air per day. Inhaled air has about 20 percent oxygen and exhaled is roughly 15 percent oxygen by mass. Are oxygen bars harmful? Oxygen bars should not be used by anyone with pre-existing respiratory or vascular cond...
It's not really the number of seconds that's key, however, so much as the amount of air you're taking in during that breath. Helpfully, the ideal amount is also easy to remember: It's 5.5 liters. McKeown feels that timing your breaths is a distraction from making sure each one is...
What are the advantages of a closed circulatory system over an open circulatory system? Explain why slow, deep breathing ventilates the alveoli better than rapid, shallow breathing. Be sure to relate your response to tidal volume. (a) How many vessels does the ci...
**Tidal volume (VT)** is the amount of gas expired in each breath, usually about half a liter. **Dead space volume (VD)** is the sum of the "anatomic" dead space, which is wasted airway space, and the "physiologic" dead space, resulting from alveoli that are getting...
What is someone's sugar level during a diabetic coma? Blood sugar levels usually exceed 600 milligrams per deciliter in hyperosmolar hyperglycemia syndrome, which can cause diabetic coma. Untreated low blood sugar (below 60 milligrams per deciliter) can also put you at a risk of diabetic coma...
While we hate to pick favorites… fall is our favorite season for being outdoors. There, we said it. After a hot & sticky summer, that first cool day of fall feels like an absolute breath of fresh air! Whether it’s going on a fall day hike or packing up for afall camping trip, ...
