High concentrations of suspended solids can lower water quality by absorbing light. Waters then become warmer and lessen the ability of the water to hold oxygen necessary for aquatic life. Because aquatic plants also receive less light, photosynthesis decreases and less oxygen is produced. The combination of warmer water, less light and less oxygen makes it impossible for some forms of life to exist. Suspended solids affect life in other ways. They can clog fish gills, reduce growth rates, decrease resistance to disease, and prevent egg and larval development. Particles that settle out can smother fish eggs and those of aquatic insects, as well as suffocate newly-hatched larvae.
Scientists estimate the volume of blood in a human body to be approximately 7 percent of body weight. An average adult body with a weight of 150 to 180 pounds will contain approximately 4.7 to 5.5 liters (1.2 to 1.5 gallons) of blood. An average child with a body weight of 80 pounds will have approximately half the amount of blood as an adult. Blood carries out many critical functions in the body.
Report Abuse. The human body has about 6 liters of blood. Some people have as few as 5, some have as much as 7, and some people may even fall outside that range. But the average is about six. Children have an average of 1.5 liters of blood, and infants have about 300 mililiters of blood. As for how much bloodloss is needed to kill a person, well.... that's rough. Some people's bodies are better at compensating than others.
