Margaret Sanger, born September 14, 1879, was a women’s rights activist who led the birth control movement and dedicated her life to fighting for access to sexual health information for women. The impact of her work can still be felt today as reproductive health is no longer a forbidden topic and access to birth control or other contraceptives is mainstream. Sanger fought for women to have access to sexual health information so they could properly educated themselves about the control they have over
Mariana Aponte Professor Leiderman ENC 1101 March 15, 2017 Abortion and Birth Control Feminism has been an important topic since the end of the 19th century. That is when the first wave of Feminism began by Elizabeth Cady Stanton who drafted the Seneca Falls Declaration to outline the new movement. Three hundred men and women joined together to rally towards equality for women. Their initial goal was to give women the chance to vote “so that [they] might have some influence over their fate”.
mouth in a bird? The choanae Where is the “voice box” for a bird? The voice box of a bird is called the syrinx and is the enlargement at the base of the trachea. Do birds have a diaphragm? They do not have a diaphragm, but they have air sacks instead. What is the function of a diaphragm in a mammal? The diaphragm separates the abdominal cavity from the thoracic cavity. It aids in inspiration of the lungs and air flow. How is a bird’s respiratory system different from a mammal’s? (Include structures
The Diaphragm muscle form and its function Summary; This essay is established or focused on the main respiratory muscle and its function. The diaphragm muscle is a skeletal muscle, which is a large flat, or the dome-shaped sheet of muscle of the body. It separates the lungs from the stomach area, or the thoracic and abdominal cavities from one another, that is used for breathing. Also, the main function occurs during breathing. It reduces intrathoracic pressure and contracts to enlarge the thoracic
MAE 546 Final Project Interferometry-based optical fiber microphone using graphene diaphragm Introduction of conventional microphones and optical fiber microphone Microphone is a kind of device which includes an acoustic-to-electric sensor that converts sound into electrical signals. Conventional microphones use the mechanism of electromagnetic induction (dynamic microphone) or capacitance change (condenser microphone). Microphones have a great many of applications in our daily lives such as telephones
In the World, the liquid medium that we know as water is the main component that keeps humans, animals and their respective ecosystems alive. Everything from trees down to the smallest leaf requires it, and it is required for any lifeform to continue to grow. Though as humanity expands and continues on an upward slope, humans as a lifeforce continue to need more. Water is a defining aspect of a community, and with the ever-rising population and human-crafted climate change coming to an all-time high
Buyer’s Spotlight: Electromagnetic vs. Electrostatic Loudspeakers In this buyer’s spotlight the physics behind electromagnetic and electrostatic loudspeakers will be used to compare, contrast and justify which is best option for sound section of an integrated home theatre system. (main points, headings) What physics principles are behind: Electromagnetic loudspeakers convert the electrical signal back into sound by the voice coils vibrating. The original sound is recorded by a microphone and is amplified

require too much expertise to be explained in short here. Without regard to price, it can be assumed that the electrostatic speakers paired up with a woofer would be the first choice for audio quality oriented consumers. The light and widespread diaphragm provides clearer and more precise sound reproduction with a greater surround effect than what one would get from standard electromagnetic speakers.
much, certain infections and disorders, and troubles with the functioning of nerves controlling the diaphragm. The diaphragm is the major muscle involve in inhalation. Occasionally the cause of a person’s hiccups is not ever discovered. Even though hiccupping is a very common to take place, scientists actually fail to know the exact result of hiccups. From studies it is concluded that the diaphragm undergoes spasms throughout a hiccup attack and that the vocal cords are engaged make the hiccup sound
and expiration. In a resting person the action of inhaling and exhaling is done passively. Inspiration involves air flowing into the lungs whereas expiration involves gases leaving the lungs. The muscles involved in the act are diaphragm and intercostal muscles. The diaphragm is an essential part of the breathing process. It is a muscle located underneath the lungs and has an ascending and descending motion (Better Health Channel, 2013). Intercostal muscles are located between ribs and differentiate
Home Remedies for Hiccups Why do we get hiccups? Hiccups is a kind of condition whereby the diaphragm unwillingly contracts. Hiccups is also a form of digestive disorder. As the diaphragm contract, the stomach breathes in air and the vocal cords closes up afterwards. And this is what result into th hiccup sound. Hiccups may be for a shorter period or longer periods. Longer hiccups could be as a result of irritation, alcoholism, medications, diabetes, metabolic disorders, nervous system disorder
posterior end of the nasal passages, then passes into the pharynx, through the glottis, and into the larynx and ultimately the trachea. Air then passes through the voice box and over the vocal cords which vibrate when air passes over them. The diaphragm is a sheet of muscle that seperates the abdonimal cavity from the thoracic cavity. The thoracic cavity is divided into three areas by membranes: The right and left pleural cavities, which surround the lungs, and the pericardial cavity where the
this stage becomes an active process such as when exercising. The diaphragm is a large muscle, shaped like a dome, which is what separates the thoracic cavity (floor of thorax cavity) and the abdominal cavity (roof of abdominal cavity). The diaphragm contracts in inspiration and relaxes in expiration. The diaphragm and external intercostal muscles contract and pulls the chest out and down (expands) to allow intake of air. As the diaphragm contracts and the chest expands, it pulls the parietal pleura
Introduction: A lung transplant is great for when your lung has got lung disease. Lung Transplant impacts the respiratory system. Some of the organs that are used in the respiratory system would be the Lungs, Trachea, Bronchi and Diaphragm. These organs listed are located in the respiratory track in the human body. Why do we need the respiratory system? We need the respiratory system so that we can have the red blood cells collect oxygen from the lungs to be transferred around the body and to have
The respiratory system is a biological system consisting of specific organs and a specific structure used for the process breathing. Respiration is accomplished through the nose, mouth, trachea, diaphragm and the lungs. The respiratory system is responsible for the inhalation of oxygen and exchanged to carbon dioxide when oxygen is exhaled. Respiration or ventilation takes place in the respiratory system. Organs of the respiratory system extend from the nose to the lungs. Respiration takes place
PRESSURE GAUGES Introduction: Pressure gauges are devices that measure the rise and fall of pressure in a contained field. Eugene Bourdon was the first person to receive the first ever patent for a tube pressure gauge. Bourdon tube pressure gauge measures the pressure of various types of fluids including steam, water and air. Gears are connected to a coiled tube. The gears measure the pressures of fluids up to 10^5 psi. There is a wide variety of pressure gauges used in transportation
knowledge of a concept called diaphragmatic breathing. Diaphragmatic breathing occurs when you consciously control the breathing mechanisms of the diaphragm. Normally, the diaphragm controls breathing involuntarily, however, the diaphragm allows for voluntary control of breathing to an extent. To breathe correctly, you must breathe into the diaphragm, feeling the stomach and sides expand. Practice this by breathing in for four beats and out for six beats. As you improve you will be able to take in
The system that we were assigned to was the respiratory system (explain what is it) Kamal-Nasal cavity: The nasal cavity is the organ that is located in the middle of face. There are many functions of this organs such as trapping large particles so they may not be inhaled and be able to harm the lungs and it also helps to take in oxygen for the lungs. Mohammed-Pharynx: Although the pharynx is a part of the digestive system it is also a part of the respiratory system. The pharynx or the throat is
it the diaphragm and the other electrically charged plate vibrate they vibrate back and forth between each other and produce an electric current which then makes its way through the electrical cord and into the speaker and amplifies the sound. So when you talk your sound waves go through the microphone and come out as a electric waves. But underneath the dynamic and condenser microphones become into even more categories. In these categories there is 9 different types, The large diaphragm condenser
