Biology 30 Red Blood Cell Disorders & Blood Cell Activity
Red blood cels (erythrocytes) carry oxygen to the cells of the body. A condition called hypoxia (low oxygen)
can result if the number of red blood cells is diminished or if there is a problem with the hemoglobin within the
red blood cells. Study the chart below, and match the condition with the correct patient. Please note that the
information in the chart refers only to the patient's systemic circulation.

1. Which patient might be suffering from a dietary iron deficiency? How do you know?
2. Which patient may be experiencing heart failure and thus poor blood circulation? How do you know?
Which patient may recently have experienced high altitude (hiked up a mountain) where air is lower in
atmospheric coygen? How do you know?
4. Which patient may have been exposed to a poison that prevents the cells from using oxygen? How do you know?
5. Patient 2 is experiencing increased breathing. Describe the mechanism responsible.
6. Answer the following questions in relation to Patient 1:
a) How much blood is flowing through the lungs each minute?'
bj How much oxygen (in mL) is transported to the lungs each minute? Explain.
c) How much oxygen (in mL) is carried away from the lungs each minute? Explain.
dj Use the answers from bj and of to calculate the oxygen consumed each minute. Show and explain all
of your work.
Blood is often described as the "river of life" because It transports substances needed by the body. It has a fluid
pardon called plasma and a formed portion made up of the red blood cels, white blood cells, and platelets. Doctors
use blood as a diagnostic tool that can help them identify what may be happening with a patient.
Study the information in the chart below and match the patient with the correct condition.
RBCs (x 10'imL blood)
WBCs (x 10 imL blood)
Platelets (x 10'imL blood)

7. Which two patients may be having difficulty with blood dotting? How do you know?
8. Which two patients might appear tired and lack energy? How do you know?
9. Which patient is likely fighting off an infection? How do you know?
