Forks over Knives

Remember that your homework is to watch Forks over Knives. If you can't find it on Netflix or Hulu or whatever service like that you have here is a link to a free version. You will have a lot of commercials and pop ups with this one so if you have access to it through another source it would be more pleasant to watch there. cosmosdocumentaries3.blogspot.ca/2013/07/forks-over-knives-documentary-film.html
If you get interested and want to pursue this further, I suggest reading The China Study by T Colin Campbell. 


Circulatory, Respiratory, and Nervous System Test.
The information listed below is supplemental(not in place of) to the book and what we talked about in class. Everything will be fair game for the test.

Read the following information and article. It is information about the circulatory system. We talked about a lot of this in class but it is a good resource. 
  1. Life cycle of the red blood cell
Red blood cells (also called erythrocytes) are shaped like slightly indented, flattened disks. RBCs contain the iron-rich protein hemoglobin. Blood gets its bright red color when hemoglobin picks up oxygen in the lungs. As the blood travels through the body, the hemoglobin releases oxygen to the tissues.
Hematopoeisis-is the formation of all blood cells. Erythropoeisis is the specific formation of RBC. Red blood cells form from stem cells in the marrow of bones of the skull, vertebrae, sternum, ribs, pelvis, and ends of long bones.
The formation of a red blood cell takes about 2 days. The body makes about two million red blood cells every second.
  • The body contains more RBCs than any other type of cell, and each has a life span of about 4 months.
  • Each day, the body produces new RBCs to replace those that die or are lost from the body.
  • The life span of a red blood cell is approximately 120 days but may be removed out of circulation at any time if it is severely damaged and non-functional.
  • Most of the red blood cellsself destruct rather than being actively removed from the circulation and destroyed. The primary site where this occurs is in the spleen.
  • Red blood cells are being made all of the time in the bone marrow inside many bones of the body, such as the bones of the pelvis and thighs.
  • They live for about 4 months, then are broken up and much of the contents are used to make new blood cells.
  • Phagocytic cells (macrophages ) remove the oldest cells from the bloodstream; amino acids are returned to the blood, iron to the marrow, and heme groups converted to bilirubin.
Hypoxia is the stimulus to tell the kidneys to produce erythropoietin(hormone). Erythropoietin stimulates the bone marrow to begin erythropoeisis.
Red cell count remains rather constant at 5.4 million/microliter for males and 4.8 for females.

No Test This week. With the move I am not going to be able to get your test out to you before Tues at the earliest. Come to class next Tuesday prepared to do lab and I will send the test out next week and it will be Due Wed, Sep 7. Don't wait to study. Go ahead and start studying so if you have questions about the material you can ask them in class next week. 
Here is a simplified and clarified description of the Endoplasmic Reticulum
  • If the endoplasmic reticulum (ER) has ribosomes attached to it, it is called rough ER; if it does not, then it is called smooth ER.
  • The proteins made by the rough endoplasmic reticulum are for use outside of the cell.
  • Functions of the smooth endoplasmic reticulum include synthesis of carbohydrates, lipids, and steroid hormones; detoxification of medications and poisons; and storage of calcium ions.
