Slide 1

Plasma Straw colored, nonliving part of blood. 90% Water Helps to regulate body temperature Contains Electrolytes Plasma transports blood cells, products of digestion and hormones throughout the body.

Slide 2

How much blood is in the human body? About 5 liters

Slide 3

Red Blood Cells Erythrocytes Shaped like round plates indented in the center. Have no nucleus

Slide 4

Questions The Average adult has about __________ liters of blood? 5 Describe Plasma? Plasma is the straw colored, non-living part of blood. It is 90% water. Name 2 materials carried by plasma? RBC, Hormones, Digested materials.

Slide 5

Why is blood red? Blood is red because it contains hemoglobin and iron rich pigment.

Slide 6

What does hemoglobin do Hemoglobin picks up the oxygen molecules and drops off CO2

Slide 7

Carbon Monoxide Binds to RBC better than oxygen. Not good Kills us silently Cant smell it or taste it.

Slide 8

Questions Why is blood red? Because it contains hemoglobin What does hemoglobin do? Hemoglobin carries oxygen What is the shape of a red blood cell? How does carbon monoxide poisoning occur?

Slide 9

Anemia Occurs when the blood does not have enough hemoglobin. Treated by taking in more iron Because iron makes up hemoglobin

Slide 10

Whats wrong with this picture?

Slide 11

Sickle Cell Anemia Genetic disease Red blood cells become sickle shape Cant carry as much oxygen

Slide 12

Malaria Disease that attacks the RBC. Causes high fever If you have sickle cell shaped RBC can not get the disease.

Slide 13

White Blood Cells Fight infections Large in size Have a nucleus Phagocyte

Slide 14

Slide 15

Platelets Smallest part of blood No nucleus Live 2-4 days Involved in clotting of blood

Slide 16

http://learn.genetics.utah.edu/units/basics/blood/types.cfm There are 3 alleles or genes for blood type: A, B, & O. Since we have 2 genes, there are 6 possible combinations. Blood Types AA or AO = Type A BB or BO = Type B OO = Type O AB = Type AB Blood Types

A blood transfusion is a procedure in which blood is given to a patient through an intravenous (IV) line in one of the blood vessels. Blood transfusions are done to replace blood lost during surgery or a serious injury. A transfusion also may be done if a persons body can't make blood properly because of an illness. Who can give you blood? People with TYPE O blood are called Universal Donors, because they can give blood to any blood type. People with TYPE AB blood are called Universal Recipients, because they can receive any blood type. Rh + Can receive + or - Rh - Can only receive - Universal Donor Universal Recipient

Scientists sometimes study Rhesus monkeys to learn more about the human anatomy because there are certain similarities between the two species. While studying Rhesus monkeys, a certain blood protein was discovered. This protein is also present in the blood of some people. Other people, however, do not have the protein. The presence of the protein, or lack of it, is referred to as the Rh (for Rhesus) factor. If your blood does contain the protein, your blood is said to be Rh positive (Rh+). If your blood does not contain the protein, your blood is said to be Rh negative (Rh-). A+ A- B+ B- AB+ AB- O+ O- http://www.fi.edu/biosci/blood/rh.html RH Factors
