Anatomy and Physiology of Respiratory System
Overview

Cells in the body require oxygen to survive. Vital functions of the body are carried out as the body is continuously supplied with oxygen. Without the respiratory system exchange of gases in the alveoli will not be made possible and systemic distribution of oxygen will not be made possible. Thetransportation of oxygen in the different parts of the body is accomplished by the blood of the cardiovascular system. However, it is the respiratory system that carries in oxygen to the body and transports oxygen from the tissue cells to the blood. Thus, cardiovascular system and respiratory system works hand in hand with each other. A problem in the cardiovascular system would affect the other and vice versa.
Functional Anatomy of the Respiratory System
Nose
The nose is the only external part of the respiratory system and is the part where the air passes through. During inhalation and exhalation, air enters the nose by passing through the external nares or nostrils. Nasal cavity is found inside the nose and is divided by a nasal septum. The receptors for the sense of smell, olfactory receptors are found in the mucosa of the slit-like superior part of the nasal cavity which is located beneath the ethmoid bone. Respiratory mucosa lines the rest of the nasal cavity and rests on a rich network of thin-walled veins that warms the air passing by.
Important information about nose is the presence of the sticky mucus that is produced by the mucosa’s gland. This important characteristic moistens the air and traps the incoming bacteria and other foreign debris passing through the nasal cavity. Cells of the nasal mucosa are ciliated and it creates a gentle current that moves the contaminated mucus posteriorly towards the throat, where it is swallowed and digested by stomach juices.
In cases where the temperature of the…...

The Anatomy and Physiology of the Respiratory System

...deeper parts of the respiratory tract. So again, those meatuses act as sped bumps. They're going to kick up turbulence in the air to sallow us to filter and humidify better. And we know that the air we take in is humidified because if breathed into your hand. And next we have the hard and soft palate, which you should still be familiar with from API. The hard palate if what we call the roof of our mouth. And the palate here is made up of the maxillary bone and the palatine bone. And then hanging off the hard palate, we have the soft palate, which is made up of cartilage. That's why it's called soft because it's much more flexible. Hard palate, maxillary bone and palatine bone. And then soft palate, which is made up of cartilage. We then have the internal nares. The internal nares, this is the space right behind the meatuses, those opened space here. Next on your list is the nasal mucosa. This is the epithelial tissue that lines the inside of the nasal cavity that's going help filter and humidify that incoming air. And finally, we have the nasal septum. And the word, "septum," just means to separate or divide, It's a division. The septum, we actually learned about in our heart lab. We used that word in the interventricular septum, which separates the heart into left and right sides. So the nasal septum, as you can imagine, is going to divide the nose, the nasal cavity into a left and right side. The pharynx shared by the digestive and respiratory systems, and is......

Sc121 Unit 1 Lets Talk Anatomy

...Let’s talk anatomy Anatomy is the science of body structures and the relationships among them. It is all around us, it is basically us. The human anatomy deals with basically all the parts of humans, dealing with molecules to bones to the way we function, but that can also get misinterpreted for Physiology which is the study of body functions and how the body parts work, which in this case it is something different. Anatomy and Physiology are two concepts that are related to each other, as stated before anatomy is the science of body structures and the relationship among them, while Physiology is the study of body functions and how body parts work together. Now, with all of that being said Anatomy differs from physiology in many ways, the study of anatomy usually focuses on the shape, size, and where they are usually located at. In my perspective anatomy is more like dissection of the body, you can easily cut up the body and with your very own eyes see what the body is, or in more scientific forms using a microscope for a more detailed view. A person can easily see what they are encountering on a body and what system is connected to what. In physiology its rather more vigorous mostly involving different types of properties (chemical, physical or electrical) that make the body function. Beginning from the process of how our heart rate is regulated to more difficult systems involving different visual perceptions. Physiology is usually involved with the work of......

Seven Oraginational Approaches

...Phoenix Seven organizational approaches There are seven organizational approaches to studying the human body. The Body planes and body directions, body cavities, quadrants and regions, anatomy and physiology, microscopic, body systems, and medical specialties. Body plans and directions divide the body into many different sections such as, the front and back, the right and left and the top and bottom. The body direction stands for movement towards and away from the planes. This approach may be used in a MRI in a hospital or treatment facility. MRI’s, are used to help create an image of the body slices. This would also help divide the human body into anterior, posterior, superior, and inferior as well as distal and proximal. The body cavities are surrounded by bones and muscles in order to help support and protect the body’s organs, as well as the structure within the body’s cavities. The abdominal cavity is a part of the reproductive system which is also used for giving child birth. Quadrant and regions helps divide the abdominopelvic area in to either four quadrants or nine regions. All health care specialists’ refer to the quadrants during an internal exam. An internal exam could be done to check many things such as the colon, the pelvic, as well as all internal organs. Anatomy and physiology are used to study the structure of the body as well as how the body functions as a whole. The body can be examined as well as studied according to the functions and the......

Why Can't I Say What I Want?

...Anatomy and Physiology 1-1 Explain the importance of studying anatomy and physiology. Studying anatomy and physiology is important because knowing how normal physiology helps you recognize when something goes wrong with the body. 1-2 Define anatomy and physiology, describe the origins of anatomical and physiological terms, and explain the significance of Terminologia Anatomica (International Anatomical Terminology). Anatomy is the study of internal and external body structures. Physiology is the study of how living organisms perform functions. There are four basic building blocks of anatomical and physiological terms. Word roots, prefixes, suffixes, and combining forms. Terminologia Anatomica serves as a worldwide official standard of anatomical vocabulary. So people all over the world can have the same anatomical terms. 1-3 Explain the relationship between anatomy and physiology, and describe various specialties of each discipline. All specific functions are performed by different structures. Meaning the way a body part is made up (anatomy) gives clues on how that body part will function (physiology). Specialties in gross anatomy is surface anatomy, regional anatomy, systemic anatomy, clinical anatomy, and developmental anatomy. Specialties in physiology is cell physiology, organ physiology, systemic physiology and pathological physiology. 1-4 Identify the major levels of organization in organisms, from the simplest to the most complex...

Anatomy Intro

...Lewis: Human Anatomy and Physiology, 12th ed. Chapter 1: Introduction to Human Anatomy and Physiology Chapter 1: Introduction to Human Anatomy and Physiology I. Introduction A. The interests of our earliest ancestors most likely concerned injuries and illness because healthy bodies demand little attention from their owners. B. Primitive people certainly suffered from occasional aches and pains, injuries, bleeding, broken bones, and diseases. C. Before agriculture, infectious diseases did not spread easily because isolated bands of people had little contact with each other. D. With agriculture, humans became susceptible to worm diseases because excrement was used in fertilizers and less reliance was placed on wild plants that offered their protective substances. E. With urbanization, humans became more susceptible to infectious diseases and malnutrition. F. Tooth decay was lowest among hunter-gathers and highest among city residents. G. Preserved bones from children can reflect malnutrition because when a child starves or suffers from severe infection, the ends of the bones stop growing. When health returns, growth resumes, but leaves behind areas of dense bone. H. At first healers had to rely on superstitions and notions about magic. I. The forerunners of modern drugs were herbs and potions. J. Early medical providers developed the language of anatomy and physiology from Greek and Latin. II. Anatomy and Physiology A.

...molecules that the cells use for a variety of purposes, both functional and structural. The cardiovascular system consists of the heart, blood vessels and blood. It's a relatively simple -- though critically important -- body system, in that it operates much like a pump and series of pipes through which water might move. The purpose of the system is to circulate oxygen to your body cells, but also to circulate nutrients. Your blood then returns the waste products -- including carbon dioxide -- of various metabolic reactions to the lungs and to excretory organs, Dr. Laurlaee Sherwood explains in her book "Human Physiology."
