The human respiratory system is comprised of special organs designed to take in oxygen for the air we breathe and expel carbon monoxide, keeping us alive. Let's take a closer look at these organs and explore respiratory physiology in more detail.
of these vessels was not yet known; because they were all empty in cadavers, early anatomists supposed they all carried air. As medical knowledge advanced, however, students of anatomy realized that arteries carry blood and only the windpipe and bronchial tubes carry air. To specify the windpipe...

A STRUCTURAL peculiarity of the ``king cobra'' which I have recently ascertained while studying the anatomy of the Ophidia seems to me to be so remarkable that it must have been noticed in such comprehensive works as Bronn's ``Thierreich'' and Dr. Gadow's account of serpents in the ``...
The physical structure of the insect gut is the first line of defense against invasion by foreign pathogens [1]. The peritrophic membrane (PM) is one of the important members of the insect intestinal physical defense system, which is mainly composed of chitin and protein [1,37]. The mucus ...
Skeletal: Our bodies are supported by the skeletal system, which contains between 206 and 213 bones in an adult human body, due to slight variations in people's anatomy, according to the medical resource StatPearls. These bones are connected by tissues called tendons, ligaments and cartilage. As...
The anatomy of the digestive tract causes food to be broken down as it travels through its muscular structures. Learn through an example how the...
Respiration.When you breathe, the air enters the nasal cavities and comes in contact with the mucus membranes, which warms the air’s temperature to a more suited degree for your lungs. From the nasal cavity, the air moves down thetrachea, commonly known as the “windpipe,” and down to...
