1. The components of blood

2. Three major parts of the circulatory system
Blood
The fluid that serves as the medium of transport
Blood vessels
A system of channels that conduct the blood through the body
Heart
A pump that keeps the blood circulating through the body

3. Function of blood Transports substances throughout the body
Dissolved nutrients
Gasses
Hormones
Wastes

4. Two components of blood
Fluid component
plasma
Cellular component
Erythrocytes= Red blood cells
Leukocytes= White blood cells
Thrombocytes= Platelets

5. Plasma Made up of 90% water Straw coloured
Makes up the largest portion of blood

6. Plasma Different substances are dissolved in the plasma Hormones
Nutrients
Glucose, vitamins, amino acids, lipids
Salts
Sodium, potassium, magnesium
Wastes
urea

7. Plasma Plasma proteins Albumins Globulins Fibrinogen
Maintain osmotic pressure
Globulins
Transport nutrients
Play a role in the immune system
Fibrinogen
Blood clotting

8. Plasma

9. Cellular Components of Blood
Erythrocytes
Leukocytes
Thrombocytes

10. Erythrocytes= Red Blood Cells
Most numerus type of blood cell
Make up about 40-45% of blood
Fun Fact!
One drop of blood can contain 5million RBCs!

11. Erythrocytes= Red Blood Cells
The shape of a erythrocyte is due to the cell losing it’s nucleus over time
This shape gives the cell more surface area allowing it to absorb and release oxygen through it’s plasma membrane

12. Erythrocytes= Red Blood Cells
Red colour of erythrocytes is due to hemoglobin
Hemoglobin
Large iron containing protein
Carries about 97% of the blood’s oxygen
Picks up oxygen in the lungs- High oxygen level
Drops off in low oxygen body tissue
Picks up carbon dioxide from tissue and takes it back to lungs

13. Anemia Insufficient iron in a person’s diet can cause anemia
Results in too few blood cells in a persons body to keep tissue oxygenated
Small amounts of iron are excreted daily
Iron deficiency can also be caused by large amounts of blood loss

14. Sickle-Cell Disease Erythrocyte disorder
Have abnormal hemoglobin in their red blood cells
Hemoglobin S.
Changes the shape of erythrocytes into a crescent or sickle shape
Non flexible and can cause blood cells to bunch up and stop blood flow
Inherited disease
Passed down from parent to child

15. Sickle-Cell Disease

16. Erythrocytes= Red Blood Cells
Have a relatively short life span
About 4 months
Formed in bone marrow
Soft interior of bones
Chest
Upper arms
Upper legs
Hips

17. Erythrocytes= Red Blood Cells
Dead or damaged red blood cells are removed from circulation by the
Liver
Spleen
RBCs are broken down and release their stored iron
The blood carries the iron back to the bone marrow where it is used to make new hemoglobin for new erythrocytes

18. Liver
Spleen

20. Leukocytes= White Blood Cells
Make up less than 1% of blood
Play a function in the immune system

21. Leukocytes= White Blood Cells
Five common types of Leukocytes
Neutrophils, Basophils, Eosinophils
Ingest bacteria by phagocytosis
Originate from Bone Marrow
Monocytes
Turn into Macrophages
Migrate into liver, lymph nodes, and lungs
Lymphocytes
B and T cells
Immediate immune response

22. Leukocytes= White Blood Cells
Leukemia- Cancer of the leukocytes
Abnormal leukocytes are produced in the bone marrow
Cells continue to grow and divide and crowd normal leukocytes
Results in difficulty in the body to
fight infection
Control bleeding
Transport oxygen
