Front

What are the normal lab results for

Hemoglobin

Hematocrit

Serum Iron

Back

Hemoglobin: 12-15 g/dl

Hematocrit: 36-46%
Serum Iron: 50-70 mcg/dl

Front

How are the hemoglobin, hematocrit, and iron levels related in blood physiology?

Back

They all have to do with the red blood cell (RBCs)

Front

Why would the loss of so much blood cause these specific symptoms in this patient of muscle weakness, shortness of breath & fatigue

Back

The loss of so much red blood cells that carry oxygen caused LESS oxygen to reach her muscles and tissues

Front

What are the three functions of blood

Back

Transport

Regulation

Protection

Front

What does the transport function of blood include

Back

- Delivering O2 and nutrients to body cells (primary function of blood)

- Transporting metabolic wastes

* CO2 to lungs

* other substances to kidneys for elimination

- Transporting hormones from endocrine organs to target organs

Front

What does the regulation functions of blood include

Back

- maintaining body temperature by absorbing and distributing heat

• * Vasodilation and Vasoconstriction of peripheral vessels divert warm blood

- maintaining normal pH using buffers

* Carbonic acid (H2CO3)

* Bicarbonate (HCO3-)

- maintaining adequate fluid volume in circulatory system

* water hydration vital to plasma in blood

* Blood fluid volumes help BP and heart function

Front

What are the functions of protection in blood

Back

- Preventing infection

* immune-fighting compounds are carried in blood

~ White blood cells (WBCs)

~Antibodies

~ Complement proteins

- Preventing blood loss (hemorrhage)

* Plasma proteins and platelets in blood initiate clot formation

Front

What is the only fluid tissue in the body

Back

Blood

Front

What is the composition of blood

Meaning what kind of tissue it is

Back

Type of connective tissue

- matrix is nonliving fluid called plasma

- cells are living blood cells called formed elements

Front

What are the formed elements of blood

Back

1. Erythrocytes (red blood cells or RBCs)

2. Leukocytes (white blood cells or WBCs)

3. Thrombocytes (platelets- clot)
