Out with the old and in with the new—that's what the respiratory system does, delivering air to the lungs, bringing oxygen into the body, and expelling the carbon dioxide back into the air. Understanding the structure and intricacies of the respiratory system is vital to human anatomy. The respiratory system is made up of more than just the lungs; it also includes your nose, throat, larynx, windpipe, bronchi, alveolar ducts, and respiratory membrane.The function of the respiratory system is to deliver air to the lungs. Oxygen in the air diffuses out of the lungs and into the blood, while carbon dioxide diffuses in the opposite direction, out of the blood and into the lungs. Respiration includes the following processes:
External respiration is the process of gas exchange between the atmosphere and the body tissues. In order to accomplish this task, the following events occur:
1.Pulmonary ventilation is the process of breathing—inspiration (inhaling air) and expiration (exhaling air).
2. Gas transport, carried out by the cardiovascular system, is the process of distributing the oxygen throughout the body and collecting CO 2 and returning it to the lungs.
Internal respiration is the process of gas exchange between the blood, the interstitial fluids (fluids surrounding the cells), and the cells. Inside the cell, cellular respiration generates energy (ATP), using O 2 and glucose and producing waste CO 2.
Hi there! The correct answer is a) testosterone & serotonin.

<h2>
What is each hormone & neurotransmitter responsible for?</h2><h2>
</h2>
--------------------------------------------------------------------------------------------------------------
- Testosterone is the male sex hormone that is categorized as an anabolic steroid. With a heightened (normal) level of serotonin, males would experience pubescent effects - hair growth, development and regulation of a libido (sex drive), and increases your muscle mass.
- Serotonin is a neurotransmitter that is linked to mood and cognition (thinking). If you have a surplus of serotonin, you're usually happy, cheerful, and optimistic. If you have a deficit of serotonin, however, this can lead to gloominess, negative thoughts, and you would not be as interested in your hobbies or extracurricular activities.
- Dopamine is the neurotransmitter that is linked to pleasure (eating your favorite food, hearing your favorite song, or taking a nice, hot bath after a long school day). It is also linked to some vital functions - blood pressure, sleep, and the processing of pain. Consequently, if you have a normal measure of dopamine, your body would be homeostatic - normal heart rate & blood pressure, no injuries to cause pain, and your sleep would be normal (going to bed at a decent hour and waking up at a relative time). But, if your dopamine levels are high, you can actually experience both positive and/or negative effects - heightened anxiety levels, increased energy, and difficulty sleeping. If your dopamine levels were to be low, you can experience muscle cramps, depression, or chronic fatigue.

How do our findings apply to the question?</h2><h2>
</h2>
--------------------------------------------------------------------------------------------------------------
- <u>Serotonin</u> cannot be linked to aggression because deficits of this hormone would be linked to depression or negative thoughts, but it doesn't ultimately lead to aggression. Therefore, we know that testosterone is the hormone linked to aggression, eliminating options B and D.
- Because heightened levels of <u>dopamine</u> are associated with heightened anxiety levels (a.k.a. a stressful experience), this most likely would not suffice the requirements of the question. Therefore, this would eliminate option C.
- However, because serotonin can have lower levels and these are associated with depressive thoughts, this would be a better fit. When a person is stressed, they are usually focused on what is stressing them out and steering away from what makes them happier and what they are interested in doing. Therefore, serotonin would most likely be depleted, which leaves us with option A.
--------------------------------------------------------------------------------------------------------------
<h2> What can we conclude with this information?</h2><h2 />
--------------------------------------------------------------------------------------------------------------
Using our findings, we can finally come to the conclusion that:
- Testosterone is linked to aggression and would elevate in stressful scenarios.
- Serotonin would be depleted during stressful situations.
Answer: Lower levels of estrogen and Progesterone causes MENSURATION
High level of Estrogen and Progesterone leads to OVULATION
Reduction in the level of Leutenizing and follicles stimulation homones lead to the RELEASE OF EGGS and an increased level of PROGESTERONE.
Explanation: The Uterine cycle is a Three(3) stage process which includes OVULATION, MENSURATION AND LUTEAL PROCESS.
Lower levels of Estrogen and Progesterone causes the shedding of the uterine wall accompanied by blood ( MENSURATION)
High level of Estrogen and Progesterone leads to the formation of follicles containing Egg(OVULATION)
Reduction in the level of Leutenizing hormones leads to Ovulatiion.
A surge in the level of Leutenizing and follicles stimulation homones lead to the release of the egg(LUTEAL PROCESS) and a higher level of PROGESTERONE.
Answer:
During puberty, adolescents experience a number of physical changes. These changes include growth in the larynx (voice box). In males, the front of the thyroid cartilage that surrounds the larynx tends to protrude outward, creating a feature known as the “Adam’s apple.”
It serves no purpose, it is just how mens' larynx develops.
Answer:
Explanation:
The benefits of medicines are the helpful effects you get when you use them, such as lowering blood pressure, curing infection, or relieving pain. The risks of medicines are the chances that something unwanted or unexpected could happen to you when you use them.
