Biology Fall 2011-2012 Exam Review [pic][pic] The graphs above show the results of two separate experiments on the same species of plant. Students now want to determine how the use of rainwater or bottled water affects the growth of this plant. Which conditions should be used for optimal growth as the two water types are tested?

Anemia A blood type is a classification of blood based on the presence or absence of inherited antigenic substances on the surface of red blood cells (RBCs). These antigens may be proteins‚ carbohydrates‚ glycoproteins‚ or glycolipids‚ depending on the blood group system. Some of these antigens are also present on the surface of other types of cells. Some of these red blood cell surface antigens can stem from one allele and collectively form a blood group system. It is called The ABO system and it

Spending the day in the operating room (OR) can be an exhilarating experience‚ throughout this paper I will discuss the different aspects of surgery as you follow my journey. I will discuss pre- operative care and testing preformed; operative care‚ anesthesia‚ and possible complication; and post-operative care and recovery. My day in the Operating room began with an introduction to my patient‚ an 87 year old man who was here for a left hip revision. He previously had a left total hip arthroplasty

A hematocrit measures the percentage of blood that is comprised of RBC’s and can determine a needed transfusion. Fluid volume in the blood affects hematocrit values. Hematocrit levels rise with an increase in the number of RBC’s or a decrease in the plasma volume. An elevated hematocrit is most often associated with severe burns‚ diarrhea‚ and dehydration‚ where water in tissues decreases. The low level of plasma water concentrates the RBC’s leading to the condition‚ hemoconcentration. An elevated

This condition occurs when there is an incompatibility between the blood types of the mother and baby. * "Hemolytic" means breaking down of red blood cells * "Erythroblastosis" refers to making of immature red blood cells * "Fetalis" refers to fetus ------------------------------------------------- What causes hemolytic disease of the newborn (HDN)?

The cell has no nucleus‚ so more haemoglobin molecules can be included. 2 Function of haemoglobin in Transporting Oxygen: * transport of O2 * transport of some CO2 from body cells to the lungs * conversion of CO2 to HCO3- by the action of the enzyme carbonic anhydrase in the RBC; HCO3- produces H+

The Blur of Having a Premature Baby In the United States‚ there are one in ten babies is born premature. It is important to know the complications of premature babies and how to try prevent having a preemie. “A premature birth is when a baby is born before 37 completed weeks of pregnancy. A full-term pregnancy is 40 weeks” ("Premature Babies." MedlinePlus.). Knowing a person that has had a premature baby makes knowing the possible affects interesting. Things that are good to know are health

and Physiology II Unit 5 Gas Exchange Explain how the gas laws and the properties of gases affect the gas exchange between the lung‚ blood‚ and tissues. The major function of the respiratory system is to provide the body with oxygen and rid the body of carbon dioxide. Gas exchange occurs between blood and alveolar air (external respiration) and between blood and tissues (internal respiration).Gas exchange process depends on properties of gasses. Based upon the Basic properties of Gases; Dalton’s

Lecture 1 Slide 1 ● The first type of blood cells that we will focus on are the erythrocytes‚ also called the red blood cells. These are the cells that transport oxygen in the blood from the lungs to the tissues. These cells also help transport some of the carbon dioxide from the tissues to the lungs. The main function of erythrocytes‚ namely oxygen transport‚ is carried out by the protein that makes up the majority of the protein composition of the cell‚ hemoglobin. We will also be looking at how hemoglobin delivers oxygen
