Blood Cell Circulation....in body

"An individual blood cell takes about 60 seconds to make a complete circuit of the body."

A blood cell (also called blood corpuscle) is any cell of any type normally found in blood. In mammals, these fall into three general categories: 

red blood cells — Erythrocytes 

white blood cells — Leukocytes 

platelets — Thrombocytes 

Together, these three kinds of blood cells sum up for a total 45% of blood tissue by volume (55% is plasma). This is called the hematocrit and can be determined by centrifuge or flow cytometry.

Lack of Sleep - Death

"A person will die from total lack of sleep sooner than from starvation. Death will occur about 10 days without sleep, while starvation takes a few weeks."

Cough - Spped

"A cough releases an explosive charge of air that moves at speeds up to 60 mph."

A cough, in medicine, is a sudden and often repetitively occurring defense reflex which helps to clear the large breathing passages from excess secretions, irritants, foreign particles and microbes. The cough reflex consists of three phases: an inhalation, a forced exhalation against a closed glottis, and a violent release of air from the lungs following opening of the glottis, usually accompanied by a distinctive sound. Coughing can happen voluntarily as well as involuntarily, though for the most part it is involuntarily.

A cough is a protective, primitive reflex in healthy individuals, and thus can occur while a person is unconscious. The cough reflex is initiated by stimulation of two different classes of afferent nerves, namely the myelinated rapidly adapting receptors, and nonmyelinated C-fibers with endings in the lungs.

Crocodile - Tounge

"A Crocodile cannot stick out its tongue".

A crocodile is any species belonging to the family Crocodylidae (sometimes classified instead as the subfamily Crocodylinae). The term can also be used more loosely to include all members of the order Crocodilia: i.e. the true crocodiles, the alligators and caimans (family Alligatoridae) and the gharials (family Gavialidae), or even the Crocodylomorpha which includes prehistoric crocodile relatives and ancestors. Crocodiles are large aquatic reptiles that live throughout the tropics in Africa, Asia, the Americas and Australia. Crocodiles tend to congregate in freshwater habitats like rivers, lakes, wetlands and sometimes in brackish water. They are believed to be 200 million years old whereas dinosaurs became extinct 65 million years ago; crocodiles survived great extinction events.

The word crocodile comes from the Ancient Greek κροκόδιλος (crocodilos), "lizard," used in the phrase ho crocodilos ho potamós, "the lizard of the [Nile] river."

Crocodiles do not have sweat glands and release heat through their mouths. They often sleep with their mouths open and may even pant like a dog.
