Oxygen from the respiratory system is delivered by the circulatory system.
<h3>What is the relationship between respiratory and circulatory system?</h3>
The respiratory system is responsible for delivering oxygen to the circulatory system that is made up of blood vessels which carry blood to the heart and then all cells of our body. Arteries carry blood that is loaded with oxygen from the heart to all cells whereas veins carry deoxygenated blood back to the heart and then to the lungs for disposing carbondioxide. The circulatory system carries oxygen and nutrients to the cells, and removes waste products such as carbon dioxide.
So we can conclude that Oxygen from the respiratory system is delivered by the circulatory system.

Answer:
1. sports medicine
2. gene therapy
3. Adrenal gland
4. false
5. Hormones
6. To regulate body activities (like growth and immunity) by sending chemical messages
Explanation:
1. Sports medicine is the branch of medicine that is related to physical fitness, so if the question ask for someone who is interested in athletic activity, the correct answer is number 4.
2. Gene therapy is an experimental technique that in order to treat or even to prevent disease genes are used to help with their treatment, so a person who is interested in genetics and its relation with health, the correct answer is number 2.
3. Adrenal gland this is the gland that sintetice Adrenaline also known as epinephrine which is a hormone or also a medicine that plays an important role in the fight or flight response, this hormone is the one in charge of giving us several symptom like tachycardia or dilated pupils in order to survive in dangerous situations, so the correct answer to Sarah's problem is number 1.
4. False the endocrine system serves as a messenger to regulate hormone synthesis and are secreted to the circulatory system.
5. Hormones, as we have answer before hormones are regulated by the endocrine system.
6. To regulate body activities (like growth and immunity) by sending chemical messages hormones play an important part in human development and growth, these chemical messages serve to regulate the synthesis (creation) and secretion (liberation) of the hormones in the specific quantity as the body needs them.
The right answer to this question is option A. O2 in the atmosphere.
The main reason why it's a true that organisms would grow larger than we have today with more oxygen available is pretty simple to understand, their respiratory systems were smaller than we have today, and even though it was a small one, it was enough because of the higher presence and concentration of O2 in the atmosphere.
Some studies were held nowadays to check this possibility, to see if the O2 was the real main reason for this, and the animals used in it really grew bigger than usual, so by that, they confirmed their hypothesis by testing it.
