The Cardiovascular System And Its Blood Transporters Essay

In conclusion, the respiratory and cardiovascular systems are directly related in a complex manner, relying on one another to perform their physiological functions. Only together can both systems work to maintain the body’s internal balance, this is evident when physical demand is higher than normal. In order to meet this demand, the heart must pump more nutrient-rich blood around the body; however it needs oxygen to do this, in response the

Spectroscopy is the study of light. A spectrophotometer is a machine used to determine the absorbance of light at any given wavelength. It does this by using a source of white light through a prism, which gives multiple wavelengths that can be individually focused (Ayyagari and Nigam, 2007). Substances are put into cuvettes that are glass or quartz containers that light can easily travel through. The light that is being focused travels through the substance gets absorbed by the

A spectrophotometer’s purpose is to use colors of the light spectrum to determine the concentration of light absorbing molecules in a solution. (p.59) In this particular lab, our mission was to determine the protein concentration and the standard curve of the unknown sample of BSA. This, by preparing five dilutions of the unknown solution of BSA together with other known concentrations, and then experimenting by observing how the concentrations were passed through the spectrophotometer. The outcome resolved in the absorption levels being decreased, and this

Transportation has many roles in the cardiovascular system. First, our blood carries oxygen from our lungs to all of our tissues. While taking oxygen to our tissues, it also picks up carbon dioxide from them and takes it to our lungs to be removed from our body. Second, it delivers nutrients from our digestive tract to all of our body’s tissues. Third, it takes waste to our kidney’s to be removed from our body. Fourth, it

Composed of the heart, blood vessels, and blood, the cardiovascular system is the body system that carries out the tasks of pumping and transporting blood, oxygen, nutrients, and waste products, and other substances throughout the body.

Scientists use an instrument called a spectrometer to quantitatively determine the amount of light absorbed by a solution. The primary inner parts of a typical spectrometer are described below. The spectrometer has a light source that emits white light containing a vast mixture of different wavelengths of electromagnetic radiation. The wavelength of interest is then selected using a monochromator (“mono” meaning one and “chromate” meaning color) and an additional exit slit. The separation of white light into different colors (wavelengths) is known as diffraction. The selected light then reaches the sample and depending on how the light interacts with the chemical compound of interest, some of the light is absorbed and some passes straight through. By comparing the amount of light entering the sample (P0) with the amount of light reaching the detector (P), the spectrometer is able to tell how much light is absorbed by the sample.

The heart, blood and blood vessels make up the basis of the cardiovascular system also known as the circulatory system. The average human body contains approximately 5 litres of blood which is carried around the body via a network of blood vessels split into three types; arteries, veins and capillaries. The arteries are the largest of the three vessels and carry blood away from the heart. Veins carry blood to the heart and are smaller than arteries, then finally the smallest vessels known as capillaries distribute the oxygen rich blood to organs whilst simultaneously picking up the waste carbon dioxide and water from the organs to transport back to the heart where it can be pumped into the lungs to be exhaled.

A spectrophotometer is an instrument which measures the amount of light of a specified wavelength which passes through a medium. This instrument is usually used for the measurement of reflectance of solutions. Light is separate into different wavelengths and is being passed through the sample solution. The sample solution will have its own wavelength and will absorb a certain amount of light. The higher the molecular concentration, the higher the absorbance value.

Vertebrates have the ability to sustain in high and low altitude environments. Depending on the levels of oxygen in the environment, the body of a vertebrate accommodates to the changes internally through adjusting the efficiency of gas exchange in organs (lungs, skin, etc) and in the circulation of blood in the heart, vascular, and capillary systems (Webber, 2007). Four molecules of oxygen bind to a protein molecule called hemoglobin. It is made up of globulin chains that contain alpha or beta chains with an iron (Fe) atom in the center forming a haeme group. Oxygen has a high affinity to hemoglobin, and hemoglobin is essential for transporting oxygen from the lungs to the cells of tissue in the body and also returning carbon dioxide (CO2) back to lungs (Davis, 2015). Hemoglobin is essential for the survival of vertebrates, and this lab

Haemoglobin is a protein molecule found in red blood cells (RBC). Its role in the body is to transport oxygen from the lungs to the body 's tissues and then returns carbon dioxide from the tissues back to the lungs. The transportation of oxygen is only possible when haemoglobin (Hb) within the RBC binds to oxygen. (Martini & Nath, 2006)

The cardiac cell is in the heart, which is in the cardiovascular system. The cardiovascular system acts like a highway in your body. This system also includes blood vessels and blood. According to the textbook, Human Biology and Health Prentice Hall Science Explorer it states, “The cardiovascular system also transports cells that attack disease causing microorganisms” (79). This means that this system helps attack diseases that are in your body. It also eliminates waste products that are in the body. The blood in this system will carry different substances that need to be transferred into the body. There are two kinds of blood in the cardiovascular system which are oxygen-poor and oxygen-rich. This is the cardiovascular system.

Chemical equilibrium processes have a strong impact on the interactions between hemoglobin and oxygen in the circulatory system. Hemoglobin is a protein in red blood cells that carries oxygen from the lungs to body tissues and delivers carbon dioxide from the tissues back to the lungs. The delivery of oxygen to the body uses a biological equilibrium process to ensure that cells receive ample quantities of oxygen to allow for proper function and efficiency. The reaction between hemoglobin and oxygen forms the product, oxyhemoglobin, represented through the chemical equation:
