The structure of organs is always relevant to function. The function of respiratory surfaces is gaseous exchange. The structure would therefore facilitate this as follows:
1. A single layer of squamous epithelial cells.
2. A large blood supply to the surface.
3. A large surface area.
4. Counter-current flow of medium to blood. (This means that the blood and air/water are flowing in opposite directions so as to increase the concentration gradient).

What four ways that pathogens can infect humans?
Pathogens can infect humans through inhalation of respiratory droplets, contact with contaminated surfaces and objects, ingestion of contaminated food or water, and through bites from infected animals.
How many years do respiratory therapists have to attend college?
Most colleges that offer programs in Respiratory Care are Community Colleges. However, there are several four year colleges now starting to offer four year degrees in Respiratory Care. I'm a Respiratory Therapist who graduated from a four year college. In my education, I was taught that a four year program is designed to prepare prospective therapists for the advanced level of Respiratory Therapy. A two year degree allows one to enter the field "entry level". As a Respiratory Therapist (RT), you have different credentials awarded by the NBRC (National Board of Respiratory Care). The entry level therapist is known as a CRT (Certified Respiratory Therapist. After passing the NBRC's CRT exam, a person with a four year degree is eligible to sit for the RRT exam (RRT is Registered Respiratory Therapist). This can be somewhat important because not only does it provide you with a little more job security, but in a lot of cases, an RRT earns more money. Unfortunately for me, this is not the case. I am an RRT, but at my hospital, it doesn't mean more money. But I do have several friends who I went to RT school with who do make more with the RRT credential. In summary, I guess you really only need to go to college for two years, but a four year program should take you further.
What four body systems that are involved in getting oxygen to your cell?
The respiratory system helps to take in oxygen through breathing, the cardiovascular system transports the oxygen-rich blood to cells, the circulatory system distributes the oxygen to tissues, and the cellular system utilizes the oxygen for various metabolic processes within the cells.
How many lounges does the human body have?
The human body has three lounges: the mental lounge (brain), the digestive lounge (stomach), and the respiratory lounge (lungs).
The four main groups of tissues are?
Four types of tissues are: 1. connective (connects between body organs) 2. epithelial (covers the surfaces. Some conatin cilia which moves substances) 3.nervous ( conducts nerve impulses around the body for coordination) 4. muscles ( contracts to bring about locomotion/ movement)
