Answer:
b) Blood carries carbon dioxide to body tissues and removes oxygen for use by other organs.
Explanation:
Options a, c, d, e are all true statements about the contributions of the cardiovascular system to other body systems except option b which states that “Blood carries carbon dioxide to body tissues and removes oxygen for use by other organs”.
Actually, the cardiovascular system works together with the respiratory system to supply oxygen to body tissues as blood is circulated in the body, while carbon dioxide is removed from the body at the lungs. <em>In order words, carbon dioxide is removed, while oxygen is picked up as blood is transported through the capillaries of the lungs.

Explanation:
The sympathetic nervous system stimulates many parts of the body for action during times of danger.
This signalling starts when the postganglionic neuron depolarizes, and postganglionic neuron releases acetylcholine, then the acetylcholine binds to nicotinic receptor in order to transmit impulse, and further the acetylcholine binds to sweat gland’s muscarinic receptor to disrupt or inactivate the action of acetylcholine. Finally, the neuron releases acetylcholine, and the neuron exits lumbar segment of spinal cord.
The danger has now been fully interpreted.
