Transcript The major organs involved in the cardio

The major organs involved in the
cardio-vascular system are:
A.
B.
C.
D.
lungs and kidney
kidney and bladder
heart and lungs
blood vessels and
heart
• cardio= HEART
vascular=
• A & b Don’t have nothing
to do with the blood
lungs are pulmonary
syrtem
The pulmonary system
transports:
A. blood from the heart to
the body organs
B. blood from the body
organs to the lungs
C. blood between the
heart, lungs and body
organs
D. blood from and to the
body organs and heart
• Pulmonary = lungs
which supplies 0^2 to
the body removes co^2
• A & B are only ½ the
answer D is missing
the lungs
The kidney maintains
homeostasis by
A. regulating the
balance of sugar
and water levels
B. regulating the
balance of waste
and water levels
C. regulating blood
oxygen levels
D. removing excess
water from the body
• Kidney doesn’t
balance sugar or
oxygen
• D. no such thing as
excess water we want
to hold on to water
Cell
Sugar Concentration of
solution
Change in cell weight
Cell A
20%
- 0.8 g
Cell B
10%
Cell C
5%
• Cell A lost weight because:
A. Due to osmosis it lost water
because it had higher
concentration than the solution
B Due to osmosis it gained water
because it had higher
concentration than the solution
C Due to osmosis it lost water
because it had lower
concentration than the solution
D Due to osmosis it lost water
because it had higher
concentration than the solution
+0.2 g
• Osmosis = movement of
water from low solute
Concentration to high
water left the cell
• A & D do not have what
osmosis needs
Cell
Sugar Concentration of
solution
Change in cell weight
Cell A
20%
- 0.8 g
Cell B
10%
Cell C
5%
+0.2 g
• You look at cell A & C
The most likely
the environment’s sugar
change in cell B
concentration must be
would be?
between 5% to 20%
A. Lose greater than 0.8
g
B. Gain more than 0.2 g
C. Remain about the
same
•
• Solution turns form blue
to yellow increase in
acid snails don’t exhale
O^2
• carbon dioxide is acidic
snails exhale CO^2
a) Body of the snail is slightly basic
b) Snail is exhaling carbon dioxide
into the water
c) Snail is exhaling oxygen from
the water
d) Snail ingested some of the blue
liquid
Which statement concerning gas
transport in humans is correct?
A Carbon dioxide is
transported to body
cells by lymphocytes
B Carbon dioxide is
transported to body
cells in the form of lactic
acid.
C. Oxygen is transported to
body cells in theform of
oxyhemoglobin by blood
vessels.
D. Oxygen is transported to
body cells in the form of
lactic acid by lymph
vessels.
• A and B are both incorrect
because they
The correct pathway for urine to
flow out of the human body is
• Ureter and the urethra are
A. bladder → ureter
both tubes connecting
→ kidney
bladder and kidney
→ urethra
• Bladder stores the
B. kidney → ureter
→ bladder
→ urethra
C. urethra → bladder
→ kidney → ureter
D. kidney → urethra
→ bladder
→ ureter
• All digestion begins in the month – enzymes in
the month break down starch
• Chewing starts digestion
