- 1. Construct your Interactive Notes • 5 pages of binder paper • On cover page, write: Chapter 11: Blood, your name and period, and a picture • Number the pages
- 2. Notes: Functions and Characteristics of the Blood (page 2)
- 3. Notes: Functions and Characteristics of the Blood (page 2) • Blood is the only liquid tissue in the body. It is a connective tissue.
- 4. Notes: Functions and Characteristics of the Blood (page 2) • Blood is the only liquid tissue in the body. It is a connective tissue. • Consists of formed elements (cells and cell fragments) in a liquid intercellular matrix (plasma)
- 5. Notes: Functions and Characteristics of the Blood (page 2) • Blood is the only liquid tissue in the body. It is a connective tissue. • Consists of formed elements (cells and cell fragments) in a liquid intercellular matrix (plasma) • Average adult blood volume is around 5 liters (8% of body weight)
- 6. Notes: Functions and Characteristics of the Blood (page 2) • Blood is the only liquid tissue in the body. It is a connective tissue. • Consists of formed elements (cells and cell fragments) in a liquid intercellular matrix (plasma) • Average adult blood volume is around 5 liters (8% of body weight) • Heavier and more viscous than water. pH = 7.4
- 7. Blood Functions • Transportation: Blood transports oxygen and nutrients to cells, CO2 and waste away from cells, hormones to target tissues
- 8. Blood Functions • Transportation: Blood transports oxygen and nutrients to cells, CO2 and waste away from cells, hormones to target tissues • Regulation: Helps maintain stable body temperature, pH, water and electrolyte levels
- 9. Blood Functions • Transportation: Blood transports oxygen and nutrients to cells, CO2 and waste away from cells, hormones to target tissues • Regulation: Helps maintain stable body temperature, pH, water and electrolyte levels • Protection: Clotting prevents fluid loss, white blood cells protect body against disease
- 10. Blood Composition • Plasma (55%): Yellow liquid that is 90% water, with dissolved proteins, salts, and nutrients
- 11. Blood Composition • Plasma (55%): Yellow liquid that is 90% water, with dissolved proteins, salts, and nutrients • Formed elements (45%): Cells and cell fragments
- 12. Blood Composition • Plasma (55%): Yellow liquid that is 90% water, with dissolved proteins, salts, and nutrients • Formed elements (45%): Cells and cell fragments 1. Erythrocytes (Red Blood Cells): 99% of formed elements. Transport oxygen and carbon dioxide
- 13. Blood Composition • Plasma (55%): Yellow liquid that is 90% water, with dissolved proteins, salts, and nutrients • Formed elements (45%): Cells and cell fragments 1. Erythrocytes (Red Blood Cells): 99% of formed elements. Transport oxygen and carbon dioxide 2. Thrombocytes (Platelets): < 1%. Cell fragments. Involved in blood clotting
- 14. Blood Composition • Plasma (55%): Yellow liquid that is 90% water, with dissolved proteins, salts, and nutrients • Formed elements (45%): Cells and cell fragments 1. Erythrocytes (Red Blood Cells): 99% of formed elements. Transport oxygen and carbon dioxide 2. Thrombocytes (Platelets): < 1%. Cell fragments. Involved in blood clotting 3. Leukocytes (White Blood Cells): < 1%. Function as part of the immune system
- 15. Color a sample of centrifuged blood (page 3) • Glue the picture in at the top of page 3 • Use accurate colors (yellow for plasma, red for erythrocytes)
