Which organ system is different in males and females?
The reproductive system is the only body system that differs substantially between males and females. Both male and female reproductive systems produce sex-specific sex hormones (testosterone in males, estrogen in females ) and gametes (sperm in males, eggs in females ).
Are male and female organs the same?
Male and female sex organs develop from the same tissue. Whether this tissue becomes male organs or female organs depends on the chromosomes and the presence or absence of male hormones. In males, a region on the Y chromosome triggers the development of testicles, which produce male hormones.
Which are both external organs of male and female?
The male external genitalia include the penis, the male urethra, and the scrotum. The female external genitalia include the clitoris, the labia majora, and the labia minora, which are collectively called the vulva.
How can you tell the difference between a male and female skeleton?
A female’s skeleton is usually much smoother and less knobby than a male’s. A male’s skeleton is usually thicker, rougher and appears more bumpy. ○ Due to the fact that males have larger muscles and therefore their skeletons require stronger attachment sites.
What is the largest organ in the body?
The skin is the body’s largest organ.
What are the 12 organs of the body?
Some of the easily recognisable internal organs and their associated functions are:
- The brain. The brain is the control centre of the nervous system and is located within the skull.
- The lungs.
- The liver.
- The bladder.
- The kidneys.
- The heart.
- The stomach.
- The intestines.
Can a human hermaphrodite have a baby with itself?
Hermaphrodites can either reproduce by virtue of self-fertilization or they can mate with a male and use the male derived sperm to fertilize their eggs. While virtually the entire progeny that is produced by self-fertilization is hermaphroditic, half of the cross-progeny is male.
What animal is both male and female?
A hermaphrodite is an organism that has both male and female reproductive organs and can perform both the male and female parts of reproduction. In some hermaphrodites, the animal starts out as one sex and switches to the other sex later in its life.
Is cervix male or female?
The cervix is part of the female reproductive system. Around 2–3 centimetres (0.8–1.2 in) in length, it is the lower narrower part of the uterus continuous above with the broader upper part—or body—of the uterus.
Does male have uterus?
The uterus is the womb, which is where the fetus develops. Male reproductive organs include testicles and a penis but no uterus.
At what period of life do a girl is already capable of reproduction?
Girls attain reproductive maturity about 4 years after the first physical changes of puberty appear. In contrast, boys accelerate more slowly but continue to grow for about 6 years after the first visible pubertal changes.
Who has more bones males or females?
Within the same population, males tend to have larger, more robust bones and joint surfaces, and more bone development at muscle attachment sites. However, the pelvis is the best sex-related skeletal indicator, because of distinct features adapted for childbearing.
Do females have more ribs than males?
Most people have the same number of ribs, regardless of their sex. However, researchers have noted that although they are rare in the general population, cervical ribs are more common in females than males.
Do girls have an extra rib?
The takeaway. The Adam and Eve story has led some people to believe that men have one fewer rib than women. This isn’t true. The vast majority of people have 12 sets, or 24 ribs, no matter their sex.
