What changes occur in the male reproductive system during puberty?

Circulatory System

Arteries carry oxygenated blood away from the heart to the rest of the body.
The right ventricle pumps deoxygenated blood into the lungs.
Left ventricles have thicker and muscular walls because they need to pump blood to the entire body, requiring more pressure.
A septum separates the heart chambers to prevent mixing of oxygenated and deoxygenated blood.
The pulmonary artery carries deoxygenated blood to the lungs.
Arteries carry blood away from the heart into different body parts.
Capillaries allow for the exchange of oxygen and nutrients with cells.
Veins return blood back to the heart.

Heart Function

It is important for oxygenated and deoxygenated blood not to mix inside the heart to maintain proper oxygenation and circulation.
Valves are responsible for preventing the back flow of blood in the heart.

Puberty

Puberty generally begins in boys around 10-14 years old.
Testosterone is responsible for the development of secondary sexual characteristics in males during puberty.
The female gonads (ovaries) are located in the pelvis.
FSH (follicle-stimulating hormone) stimulates the development of follicles in the ovaries during puberty.
The male reproductive system undergoes a growth spurt during puberty, leading to the development of testes, epididymis, vas deferens, and penis.
During puberty, the male reproductive system matures, allowing for sperm production and fertility.

Test your knowledge of the human circulatory system with this quiz. Explore the pathways of oxygenated and deoxygenated blood flow, and learn about the structures, such as valves, that help maintain the circulation of blood throughout the body.
