should be an increase in the release of oxygen by haemoglobin. The oxygen dissociation curve (ODC), which was created, using the data collected in the experiment, demonstrates that the hypothesis was accurate. In a similar experiment titled, “Continuous Determination of the Oxygen Dissociation Curve for Whole Blood”, Rossi-Dernardi et al. (1975) found that the pH of the blood used and the partial pressure of oxygen had an effect on the affinity of oxygen in haemoglobin. The shape of the ODC in…

The heart works by pumping the blood throughout the internal circulatory system to deliver the oxygen and nutrients to the body cells. There are some features about the heart which allows more efficient respiration system. The heart have a left atrium and left ventricle. The left side of the heart is called systemic circulation which only pumps the…

supplemental oxygen is valuable in many clinical situations, excessive or inappropriate supplemental oxygen can be harmful”(Malhotra). This is known as oxygen toxicity.” Too much oxygen can have negative effects on brain, eyes, and lung development. All NICU infants are at risk for oxygen toxicity because of the increased exposure to oxygen and decreased antioxidant defenses”). Since oxygen toxicity is a reality in the NICU we should always treat oxygen as a drug. We should limit oxygen to an as…

A) The Earth’s early atmosphere had no oxygen and was made mostly of nitrogen, with some carbon dioxide, water vapour and hydrogen compounds such as methane and ammonia. Within million of years life evolved in the oceans. 3.2 billion years ago photosynthesis had evolved with the first oxygen producing cyanobacteria, similar to today’s blue-green algae. At first, the oxygen given off simply reacted with the rocks, but gradually it built up in the oceans and started to bubble out into the…

The uptake of oxygen into muscles is what facilitates muscle contraction. Oxygen that is obtained through breathing by the lungs is transported to the rest of the body, as well as the heart by means of haemoglobin. The rate of liberation of oxygen from haemoglobin has an effect on the quantity of oxygen available in the muscles for a muscle contraction to ensue. The higher the oxygen concentration in the muscle the greater the force of muscle contraction. Temperature has an effect on the…

The pH of something can be determined by using the specific pH scale. The scale is based off of numbers ranging from 0 to 14. The lower the number is the more acidic something will be and the higher the number is the more basic something will be. It is important to note that 7 act as the neutral number, where neither it is considered acidic of basic (5). It is found that rain water that is unpolluted is coincides with carbon dioxide and has a pH of 5.6. Often, the pH around the world of…

the effect of light intensity on plant growth through counting the amount of oxygen produced. Hypothesis: If the light intensity increases, than so does the rate of photosynthesis (which a major factor for plant growth). If the rate of photosynthesis increases, than the rate of Oxygen produced as a product also increases, if the rate of photosynthesis decreases than the exact opposite will happen to the amount of oxygen. Scientific explanation: As the light intensity increases so will…

1) With the increase in aquatic depth, Po2 & Pn2 increase. Increasing Po2 in the atrial blood will provide the necessary oxygenation to other vital organs as well as the brain unless the diver depletes his/her oxygen supplies which results in a state of hypoxia (Caton-Richards. M, 2013). It is also said that Po2 along with increasing depth plays a role with inhibiting the urge respirate thus, allowing the diver to stay under water longer. Pn2 on the other hand activates the urge to respirate.…

The respiratory system is a system that deals with how animals receive their oxygen, and not so surprisingly there are many ways different ways animals do this. Humans have an organ called the lungs which helps us inhale oxygen, but fish do not. Fish usually use gills to breathe but there are some exceptions such as the lungfish. The lungfish is one of the only types of fish that have lungs. This is why today we will compare the differences between the lungfish and human respiratory systems. We…

takes on the R (relaxed) state (Hudon-Miller, 2012b). Another difference arises when oxygen binds to the hemoglobin, resulting in a change in the shape of the protein. In the deoxygenated state, the heme group forms a domed shape; and in the oxygenated state, the heme group takes on a planar shape (Hudon-Miller, 2012b). A2) The relationship between pH and the ability of hemoglobin to bind and release oxygen is referred to as the Bohr Effect. The blood’s pH level is greatly influenced by the…
