Question

which statement best describes an interaction between the muscular system and the respiratory system?
a the hormone adrenaline causes blood vessels to contract and send more blood to major muscles.
b metabolic wastes generated by muscle cells are eliminated in urine.
c the diaphragm contracts causing the chest cavity to expand, which draws air into the lungs.
d nutrients absorbed in the small intestine are transported in blood to the brain.
1)
the body sometimes needs to send messages long distances by releasing hormones into the bloodstream. the hormones are then carried to the target location.
which body systems are involved in this interaction?

1. move the correct answer to each box. not all answers will be used.

digestive circulatory respiratory nervous endocrine immune
the system releases hormones into the bloodstream, and the system carries them to the target location.

Explanation:

1. For the first question, the diaphragm is a muscle. When it contracts, it expands the chest - cavity and allows air into the lungs, which is an interaction between the muscular and respiratory systems. Option A is about the cardiovascular and endocrine systems, option B is about the muscular and excretory systems, and option D is about the digestive and circulatory systems.
2. Hormones are released by the endocrine system and carried to target locations by the circulatory system.

Answer:

1. C. The diaphragm contracts causing the chest cavity to expand, which draws air into the lungs.
2. The endocrine system releases hormones into the bloodstream, and the circulatory system carries them to the target location.
