Composition Of The Blood

Question 1

Plasma

Answer 1

Watery, salty fluid making up more than half the volume of blood
Red,white blood cells & platelets carried in plasma
Waste carbon dioxide from cells dissolves in plasma to be transported to lungs

Question 2

Red blood cell

Answer 2

Carry oxygen to tissues, red color provided by hemoglobin

Question 3

White blood cell

Answer 3

Destroys microorganisms and produces antibodies

Question 4

Platelets

Answer 4

Membrane enclose fragments of specialized cells, when fragments activated they form blood clots

Question 5

Blood buffer

Answer 5

Regulation of body pH through chemicals transported in blood

Question 6

Central pulses

Answer 6

Carotid & femoral, all others are peripheral pulses

Question 7

Blood pressure

Answer 7

Force blood exerts on walls of blood vessels
Pressure created by pulse (heart contracts) is called systolic BP
Pressure remaining after heart relaxes is called diastolic BP
Ex. 120/80

Question 8

Perfusion

Answer 8

Adequate supply of oxygen and nutrients to cells with removal of waste products

Question 9

Hypoperfusion

Answer 9

Inadequate flow of blood, not enough oxygen and nutrients transported

Question 10

ATP

Answer 10

Energy converted from glucose by cells
With oxygen: process called aerobic metabolism
Without oxygen: anaerobic metabolism - less energy more waste like lactic acid, WP make body acidotic

Question 11

Ventilation perfusion match (V/Q)

Answer 11

Coupling of sufficient amount of air with sufficient amount of blood

Question 12

Anemia

Answer 12

Reduces number of oxygen carrying red blood cells
