Did you know… • A newborn baby has about 1 cup of blood in his body. • It would take 1, 200, 000 mosquitos, each sucking once, to completely drain an average human of blood. • Blood makes up about 7% of your body weight. • It only takes 20 to 60 seconds for a drop of blood to travel from the heart, through your body, and back to the heart again.

Describe blood. • Liquid tissue • Transports SUBSTANCES throughout the body

1. Identify the 3 types of blood cells. • Red blood cells • White blood cells • Platelets

2. Identify another name for red blood cells. • Erythrocytes

3. Describe the function of red blood cells. • Transport oxygen and carbon dioxide to and from cells

• HEMOGLOBIN (protein)

4. Describe the shape of RBC’s. (What do they look like? ) • Circular • No nucleus • Disc shaped

• Biconcave

• Most numerous https: //www. youtube. com/watch? v=_ZV 5140 Oyk. E

Did you know… • A red blood can make a complete circuit of your body in 30 seconds. • There are 150 Billion red blood cells in one ounce of blood

5. Identify another name for white blood cells. • Leucocytes

6. Describe the function of white blood cells. • Identify and destroy pathogens (disease-causing organism) • Produce antibodies

• ENGULF pathogens • Produce ANTIBODIES

7. Describe the shape of white blood cells. (What do they look like? ) • Circular • Have a nucleus • Larger than rbc’s https: //www. youtube. com/watch? v=z_p. JBsqw 8 v k https: //www. youtube. com/watch? v=0 Tv. Tyj 5 FAa. Q

8. Identify another name for platelets. • Thrombocytes

9. Describe the function of platelets. • Involved in blood clotting and repair and regeneration of connective tissue https: //www. youtube. com/watch? v=--b. ZUeb 83 u. U

A. Platelets stick to edge of cut

B. FIBRIN is produced (long, sticky string) that sticks to cut vessel

C. Web like complex of strands forms to stop bleeding CLOT

D. Clot becomes hard & dry (SCAB) E. Skin cells repaired under scab and scab falls off

10. Place the blood cells in correct sequence (order) from largest to smallest. • WBC’s RBC’s Platelets

11. Identify the liquid that transports red blood cells, white blood cells and platelets. • Plasma • 90% water

12. Identify other substances that are transported by plasma. • • • Nutrients Metabolic wastes Enzymes Salt Proteins Antibodies https: //www. youtube. com/watch? v=_Wr. GROWd 3 KI

Did you know… • Coconut water can be used (in emergencies) as a substitute for blood plasma.

You can donate your plasma. During the actual blood donation process, your blood is drawn through a needle placed in a vein in one arm. Then a special machine separates the plasma (and often the platelets) from your blood sample. This process is called plasmapheresis. The remaining red blood cells and other blood components are then returned to your body, along with a little saline (salt) solution. Plasmapheresis is also used to treat the following: • Autoimmune diseases • Neurological diseases • Very high levels of cholesterol that are not reduced by diet and medications • Toxins that can get into your blood

An average adult’s body normally contains over 35 billion WBC’s. That’s 1 for every 600 -700 RBC’s.

One grain of rice = 1 cubic mm • 5 million RBC’s • 5, 000 – 10, 000 WBC’s • 400, 000 platelets

Let’s summarize… 1. Identify the four parts of the blood. 2. Describe the function of plasma. 3. Describe the function and shape of red blood cells. 4. What do red blood cells contain? 5. Describe the function and shape of white blood cells. 6. Describe the function and shape of platelets.
