Your question is the same as "Do people sink or float in fresh water?" When I breath in, I float in the swimming pool; when I breathe out, I sink. Try it.
The [human] population density.

Demographics
The density of blood plasma is approximately 1025 kg/m3 and the density of blood cells circulating in the blood is approximately 1125 kg/m3. Blood plasma and its contents is known as whole blood. The average density of whole blood for a human is about 1060 kg/m3.

The density of human fingernails and toenails is around 1.1 grams per cubic centimeter.
The density of a human tooth typically ranges from 1.2 to 1.6 grams per cubic centimeter. This density can vary depending on factors such as age, tooth type, and overall tooth health.
The density of the human head is approximately 1.04 g/cm³.
The density of a tooth can vary depending on its composition and type. On average, human teeth have a density ranging from 2.5 to 3.0 grams per cubic centimeter. This density is similar to that of bone tissue.
There are about 100 million nerve cells (neurons) in a cubic centimeter of the human brain.
muscle density and bone density
Density is defined by how compact a particular substance is. In the case of the density of water verses the human body, your body is slightly less dense than water that is why humans can float.
It can be if it is lean. If it is fat no. Note that water is 1 gram per mL. If an object floats it is less than 1g/mL If it sinks in water it is greater than 1g/mL
The same as it is for humans. Once we are buried, there we stay. Our skeletons remain where we're laid to rest. The same goes for dogs. Unless we are moved by human hands, or in the wild, possibly by another animal, both a human and dog's skeleton stays where he lays last.
The gluteus medius and minimus muscles attach to the greater trochanter in the human body.

On average, human hair has a density of about 1.06 grams per cubic centimeter. To calculate how much human hair would equal one pound, you would need approximately 453.6 grams of human hair, which is roughly equivalent to 16 ounces or one pound. The amount of human hair needed can vary depending on the thickness and length of the hair.
