Cardiovascular System Blood: Red Blood Cells (13:04)
From YouTube, produced by mrfordsclass
Red Blood Cells also known as red blood cells (RBCs) or erythrocytes are around 7.5μm in diameter. The average number (red blood cell count) is typically:

*5,200,000 per cubic millimeter ± 300,000 men

*4,700,000 per cubic millimeter ± 300,000 women



Red blood cells are made of hemoglobin. When the hemoglobin combines with oxygen it is called oxyhemoglobin, when oxygen has been released it is known as deoxyhemoglobin. The RBC initially have a nuclei during the early stages of development, they then remove the nuclei to help make room for hemoglobin. This is Lesson 4 in our Cardiovascular System (Blood) series. This is part of our Anatomy and Physiology lecture series. (05:10)

Cellular Service (Interactive Quiz Game)
From pbslearningmedia.org, produced by WGBH Educational Foundation
In order to survive, every living cell in the body needs a constant supply of oxygen and nutrients and needs to have wastes removed. In this interactive game, you'll follow a small sample of blood as it travels throughout the body. The goal is to keep a few cells located at the tip of the nose alive and healthy. At various locations within the body -- locations that include the lungs, small intestine, pancreas, lymph nodes, and the target cells -- you will need to pick up or deliver oxygen, nutrients, hormones, carbon dioxide, and bacteria.

Cell Biology
From howstuffworks.com, produced by Discovery
This video explores the reproduction of cells. All forms of life have the same base and biochemistry -- cells. The DNA in a cell varies depending on the species. This clip from "Assignment Discovery" on Discovery Channel shows the differences. It moves rapidly and so a word wall or handout would be of benefit to the review of the material. If you let the video run there are additional videos that add depth to the lesson. (01:21)

How Cells Divide: Mitosis vs. Meiosis (Interactive)
From pbslearningmedia.org, produced by WGBH Educational Foundation
All cell division is not the same. Cells can divide by mitosis, so each daughter cell retains a full set of chromosomes, or by meiosis, which halves the chromosomes and produces sperm and eggs. Making a baby with the correct number of chromosomes is therefore crucially dependent on meiosis. This Flash feature from NOVA: "18 Ways to Make a Baby" provides a step-by-step, side-by-side comparison of meiosis and mitosis.

Halo Explains the Plant Cell
From YouTube, produced by Dalton Bishop, Ian Groenert, and Josh Baber
A student made video project was made using Halo PC. It highlights the plant cell and structures. Uses halo figures to show how a plant cell defends itself against outsiders. It goes through each of the parts and talks about their jobs. Audio quality is somewhat low due to the amateur video production but information is accurate and the Halo characters are relevant to students.  Key words include: cell wall, microtubule, ribosome, vacuole, chloroplast, endoplasmic reticulum, golgi body, mitochondria, and nucleus. The project ends with a music video and images of each organelle. Run time 08:14.
