Fetal hemoglobin reaches higher saturation at lower oxygen partial pressure.īecause of cooperativity, adult and fetal oxygen-hemoglobin dissociation curves appear as follows.īeyond its ability to carry oxygen, hemoglobin is also effective as a blood buffer. One way in which hemoglobin accomplishes its goals is through the phenomenon of cooperativity. Cooperativity refers to the ability of hemoglobin to change its oxygen binding behavior as a function of how many other oxygen atoms are bound to the molecule.įetal hemoglobin shows a similar pattern of cooperativity, but has unique binding characteristics relative to adult hemoglobin. Natural selection has overcome this apparent contradiction by making hemoglobin exquisitely sensitive to conditions in its microenvironment. It must at once be optimized to absorb oxygen, and to offload oxygen. Hemoglobin thus has a fundamentally contradictory set of goals. Hemoglobin functions to maximize oxygen delivery to tissues, while simultaneously maximizing oxygen absorption in the lungs. It exists within erythrocytes, and binds up to four diatomic oxygen molecules simultaneously. I think a useful addition to the power point would be a slide containing information on how much blood is in the body and even things like how many times per minute the heart beats.Hemoglobin is the principal oxygen-carrying protein in humans. While power point is short and does not contain a lot of information, it does a very good job of describing exactly what happens every time the heart beats. Throughout the power point, Megan does a good job of using illustrations and drawings to show exactly what is happening at each stage of the heart beating. After exiting the heart, the oxygenated blood is sent to the entire body before returning back to the heart to start again. The left atrium pushes the blood into the left ventricle and then exits the heart through the aortic valve. After being oxygenated in the lungs, the blood returns to the heart and enters the left atrium before being pushed into the left atrium. The blood is then pushed form the right atrium into the right ventricle through the tricuspid valve and then pushed out of the heart to the lungs. One from the upper half of the body and one from the lower half. She begins her explanation stating that blood enters the heart in the right atrium from two different veins. She begins with a nice title screen letting us know exactly what she chose to do her project on. She chose to do her project as a PowerPoint slideshow. Megan did her project on the flow of blood into an out of the heart. ![]()
