Flashcards in CIRCULATORY SYSTEM PT 3 - BLOOD & BLOOD PRESSURE Deck (25):
1

Describe the characteristics of Blood.
such as: (Fluid/Cell %, pH #, male/female BV)

- 55% fluid / 45 % cell
- pH 7.4
-MALE BV: 5-6L
-FEMALE BV: 4-5L

2

What is Plasma?

Fluid matrix of blood contaning nutrients, wastes, and hormones

3

Define the function of this plasma protein: Albumin

Transports protein

4

Define the function of this plasma protein: Globulins

Transport protein and immune responses

5

Define the function of this plasma protein: Fibrinogen

Blood clotting

6

Describe Erythrocytes.

(Red Blood Cell)
Oxygen carrying protein, living to 120 days.

7

Define Hemopoiesis/Hematopoiesis.

Forms RBCs

8

Define Hematocrit.

Percentage of BV occupied by RBCs

9

Define Anemia.

Low hematocrit

10

Define Polycythemia.

High hematocrit

11

Describe Leukocytes.

(White Blood Cell)
A phagocytosis in immune responses

12

Name the 3 Granular Leukocytes.

- Neutrophils/Polymorphonuclears
- Eosinophils
- Basophils

13

What is the function of Neutrophils/Polymorphonuclears?

Most common phagocytosis

14

What is the function of Eosinophils?

Allergic reactions and Parasitic infections

15

What is the function of Basophils?

Stress and allergic responses

16

Name the 2 Agranular Leukocytes.

- Lymphocytes
- Monocytes

17

What are the cells contained in Lymphocytes?

B Cells
T Cells
Natural Killer Cells

18

Define Leukocytosis.

Increase WBC count

19

Define Leukopenia.

Decrease WBC count

20

Describe the function of Platelets.

They stop bleeding and promote clotting, living to 5-9 days

21

Define Blood Pressure.

Generated by Ventricular Contractions - pressure from blood vessel walls

22

Define Systolic BP.

High arterial pressure during ventricular systole

23

Define Diastolic BP.

Low arterial pressure during ventricular diastole

24

What is Mean Arterial Pressure (MAP)?

Average blood pressure in arteries

25

Explain Vascular Resistance.
(What decreases/increases to increase blood pressure?)

Decrease lumen size
Increase blood viscosity
Increase vessel length

=
Increase in Blood Pressure
