Red and white blood cells are the two types of blood cells in the human body. Red blood cells transport oxygen around the body which is transferred through the bloodstream. It moves oxygen into the body and then removes it. They are absorbed through its haemoglobin.

Continued on in the semester Ms. Gussow has her students do extended drawings. In these drawings, they center in on certain parts of the human body. By now, they have shortened their time on them. "This is the best way

Dissecting helps students appreciate the complexity of organisms, by actually being able to come in contact and see up close instead of learning about it through a textbook. Students will become more involved if they are able to do something, rather than just listen as they will mostly not retain anything. Therefore, speaking from experience the dissection is geared more for hands- on learners, but, it enables all students to practice their observational and following instruction skills. Comparing notes with other students this dissection enabled everyone to come up with a better visualization of how all the organs are interconnected in the human body. Looking through the textbook at pictures does not give an

Write a brief description of the three slides (Neuron, Spinal Cord Smear and C.S of Myelinated Nerve Fibers) as though you were explaining it to someone who cannot see the slide.

1. Introduction Babesias are tick-transmitted hemoprotozoan parasites belonging to the phylum Apicomplexa. These parasites are etiological agents of babesiosis that infect a wide spectrum of mammals thereby causing major health and economic problems in the livestock industry throughout the world. Babesia bigemina is one of several Babesia species known to cause bovine babesiosis. The disease is clinically manifested by anemia, fever, hemoglobinuria, and the presence of parasites in the host erythrocytes (Homer et al., 2000).
