Cardiovascular Lecture 13

Question 1

Plasma Proteins

Answer 1

Albumin, Globulin, Fibrinogen

Question 2

Albumins

Answer 2

most abundant, osmotic pressure, transport lipid soluble substances

Question 3

Globulins

Answer 3

Transport substances, clotting, immune function

Question 4

Fibrinogen

Answer 4

precursor clotting protein

Question 5

Erythrocytes

Answer 5

• Red blood cells
• Biconcave, no nucleus
• Hemoglobin: transports 02, CO2, H+, CO

Question 6

Atria

Answer 6

upper chambers, receive blood from the body

Question 7

Ventricles

Answer 7

Lower chambers, pump blood out to body

Question 8

Atrioventricular valves

Answer 8

loose flaps of tissue between atria and ventricles, prevent backflow to atria

Question 9

Semilunar valves

Answer 9

• Stiff valves between ventricles and exit valves

- Prevent backflow to ventricles

Question 10

Right ventricle

Answer 10

-Pumps blood out pulmonary artery to (to lungs to get oxygenated)

Question 11

Left ventricle

Answer 11

pumps blood out Aorta (to body to deliver O2)

Question 12

Hear valves

Answer 12

• No valves between the atria and the veins
• Four interconnecting rings of dense connective tissue surround and support the four valves
• Electrical insulation between atria and ventricles
