The Human Body is An Example of Amazing Efficiency Essay

I obtained the results from the experiment supported my predictions because as the the concentration Na+ Cl- was increased from 5 mM to 10 mM (by adding more Na+ Cl-), the osmotic pressure also increased. However, after the membrane was changed to 50 MWCO, the Na+ Cl- molecules could diffuse easily through the membrane and did not caused an increase in osmotic pressure.

Everyday amazing things happen in the human body. One of the things that happens is the way we take a breath, how we are able to use that breath to sustain life. As a breath is taken in, there’s many different physical and gas laws that take place to allow it to happen. With Hooke’s law I will be discussing what it is, how it relates to respiratory care, and the medical advances it may include.

When air is pumped in a ball, the amount of air molecules crammed into one place is increasing. This leads to the rise of air pressure within the ball. Air pressure can be

The effect that increasing Na+Cl- concentration had on osmotic pressure was that the pressure also

In conclusion, without the assistance of Poiseuille’s law, a patient with bronchial constriction would not get the adequate amount of oxygen to feed the tissues. Poiseuille’s law states that if the radius of a tube decreases by sixteen percent, the flow rate will decrease by half. In today’s modern medicine

Think about the gas laws we are studying. Boyle’s law tells us that pressure and volume are inversely proportional. Charles’ law states that volume and temperature are directly proportional. We also know that pressure and temperature are directly proportional. Discuss at least one instance in your personal experience where you have seen one or more of these laws in action.

The presence of fluid in the alveolar space could potentially cause the lung capacity to be effected as well.

If an air bubble was present in the buret during titration, it would affect the calculated molarity of the HCl. The air bubble takes up volume in the buret, making the volume of NaOH in the buret artificially high. If the bubble came out during titration, then the volume of the NaOH added would appear to be higher than what it actually was, and would ultimately result in the calculated HCl concentration be higher than what it actually

The iron lung was a machine that used electrical bellows to generate a method of respiration. First, the patient would lie on a bed and the nurse would then position a rubber collar on the patient’s neck to latch them in tight. Next, the bed would be pushed into a metal cylinder. The rubber collar would then help secure the cylinder tight enough to not allow air in. After the collar is secured, the machine would then start respiration; furthermore, the process of inhaling was when air was released out of the tank from the expansion of electrical bellows because the pressure in the cylinder became greater than the air inside the lungs. During the process of exhaling, the pressure on the inside of the cylinder equals the pressure inside the lungs. This causes the bellows to contract which influences the contracting of the lungs

B. Given that lymph vessels carry under very low pressure, they require assistance in moving lymph, especially vessels below the level of the heart which must move lymph upwards against gravity. The 2 mechanisms which

The right side of heart will increase in size as the muscle builds up and the heart rate will increase due to compensation for the left ventricle. With auscultation, the lungs will sound crackly from the liquid in the alveoli and interstitial space and when assessing respiration rate it is likely to be above thirty breaths per minute (Lewis et al., 2014). The patient may report that they are experiencing dyspnea, nocturia, fatigue, and a productive coughing. They may appear anxious and their skin may look pale (Lewis et al., 2014).

Cystic fibrosis causes the alveoli to be filled with secretions that the patient cannot cough up or eliminate. The diffusion from the lungs to the blood is decreased because of the secretion filled alveoli. When the PaO2 is less than 60 mm Hg, the carotid bodies are triggered and send an afferent signal from the body to the brain and producing the feeling of dyspnea.

movement of water in tissues and maintain the fluidity of mucus and other secretions [3].

Imagine waking up in the morning to the discomfort of not being able to take a proper ventilation. Horrible, right? This is what people who have pleural effusions feel. I chose to do my paper on pleural effusions. Pleural effusions are a collection of fluid in the pleural space, the cavity surrounding the lungs. Typically, there is 10 mL of fluid in this space to lubricate the pleura, however when disrupted by diseases such as pneumonia, pulmonary embolisms, congestive heart failure, or cancer, fluid begins to third space and collect in abnormal amounts. The biggest challenge then becomes dyspnea and tachypnea. This is because the extra fluid decreases pressure making it difficult for the lung to fully expand. Pleural effusions

Humans today are using much more electricity than we need to in our houses and this is impacting our world more then we realise. Although electricity is a huge advantage to humans it has the complete opposite effects on our environment. By using more electricity, we are using more of the earth’s resources and if we keep going down this road then we are going to run out. The solution for this mass overuse of energy is to build houses which are more energy efficient. Features like LED lightbulbs, insulating and even positioning your house in the correct position for natural airflow instead of using air conditioning are all ways we can help improve this problem.
