What are the main parts of the male reproductive system?
in human the main parts of reproductive system are
1. the external genitalia (penis and vulva)
2.the internal organs (gametes producing gonads)(testicles and ovaries)
Penis, Vagina, Testes, Ovaries, Sperm, Egg,
*These are only parts, not functions.
What are the function of the female reproductive system?
The uterus is the pear-shaped organ that protects the baby while it is growing. The lining of it sheds once a month when a woman is not pregnant.
The cervix is a flap of tissue between the vagina and the uterus that closes when a woman is pregnant.
The vagina is the entrance to the uterus.
The fallopian tubes carry the eggs from the ovaries to the uterus. If it is fertilized, then the egg will attach itself to the lining of the uterus. If not, it will be expelled from the body through the vagina.
The ovaries are the egg-shaped storehouses for the ovum(eggs). A baby girl is born with all the eggs she will use for her entire life, which is about 800,000.
What prevents the breakdown of the corpus luteum?
The hormone human chorionic gonadotropin (hCG) helps maintain the corpus luteum during early pregnancy by signaling to the ovary to continue producing progesterone. This is important for supporting the early stages of pregnancy until the placenta is fully developed and can take over hormone production. If the corpus luteum breaks down before the placenta is capable of producing enough hormones, it can lead to a miscarriage.
What is the main functions of the circulatory system?
The circulatory system is an organ system that passes nutrients (such as amino acids and electrolytes), gases, hormones, blood cells, etc. to and from cells in the body to help fight diseases and help stabilize body temperature and pH to maintain homeostasis. This system may be seen strictly as a blood distribution network, but some consider the circulatory system as composed of the cardiovascular system, which distributes blood, and the lymphatic system, which distributes lymph. While humans, as well as other vertebrates, have a closed cardiovascular system (meaning that the blood never leaves the network of arteries, veins and capillaries), some invertebrate groups have an open cardiovascular system. The most primitive animal phyla lack circulatory systems. The lymphatic system, on the other hand, is an open system.
The main components of the human circulatory system are the heart, the blood, and the blood vessels. The circulatory system includes: thepulmonary circulation, a "loop" through the lungs where blood is oxygenated; and the systemic circulation, a "loop" through the rest of the body to provide oxygenated blood. An average adult contains five to six quarts (roughly 4.7 to 5.7 liters) of blood, which consists of plasma,red blood cells, white blood cells, and platelets. Also, the digestive system works with the circulatory system to provide the nutrients the system needs to keep the heart pumping.
Two types of fluids move through the circulatory system: blood and lymph. The blood, heart, and blood vessels form the cardiovascular system. The lymph, lymph nodes, and lymph vessels form the lymphatic system. The cardiovascular system and the lymphatic system collectively make up the circulatory system.
What is the function of the corpus luteum?
The corpus luteum secretes progesterone & other hormones to maintain early pregnancy which maintains the uterine lining during the first months of pregnancy.
The corpus luteum in the ovary results from the release of an egg. It now produces progesterone to maintain the endometrium of the uterine walls.
The corpus luteum is a "yellow body". Before it released the egg, it was white and referred to as the corpus albicans (white body).
What are the main functions of female reproductive system?
The main functions of the female reproductive system are to produce eggs, facilitate fertilization by sperm, provide a suitable environment for a developing fetus in the uterus, and give birth to a baby. Additionally, the system produces hormones that regulate the menstrual cycle and support pregnancy.

How does a ciliated cell move an ovum?
Cilia are present in your fallopian tubes. They push the egg to wards the uterus. By the time the fertilized egg reaches the uterus, it is ready for implantation. That is the beauty of nature.
Why is the ovum big and why it doesn't move?
The ovum is bigger than sperm because it contains nutrients and organelles needed to support early embryonic development. It does not move due to its size and structure, as well as the surrounding cells and reproductive structures that help guide it toward the sperm for fertilization.
What are the disorders of the reproductive system?
Disorders that may affect the proper functioning of the reproductive system include abnormal hormone secretion, sexually transmitted diseases , and the presence of cancerous tissue in the region.
Why does the endometrium have many cells but no collagen and elastic fibers?
Because the endometrium is an epithelial tissue. Collagen and elastic fibers are produced by Fibroblasts which are found in connective tissue not epitheliam. Does that answer your question? Or do you want a more indepth response?
What is the function of the ovary?
The ovary is an organ in female animals which produces eggs. It also produces hormones which regulate other female sex organs.
What are the 3 main functions of the circulatory system?
there are more than 4.
transports deoxygenated blood from heart to lungs and oxygenated blood from the lungs to teh heart.
transports oxygenated blood from teh heart to tissues and deoxygenated blood from teh tissues to teh heart.
distributes nutrients (e.g. glucose, free fatty acids, amino acids) to cells
removes metabolic wastes (e.g. carbon dioxide, urea, lactate) from periphery for elimination or reuse.
regulates pH to control acidosis and alkalosis
transports hormones and enzymes to regulate physiological function
maintains fluid balance to prevent dehydration
maintains body temperature by abosorbing and redistributing heat.
What is the main function of reproductive system?
The major function of the reproductive system is to ensure survival of the species, by creating the gametes (sperm and ova, or eggs) that will combine to create new offspring for the parents.
What effect does marijuana have on the reproductive system?
Marijuana use can affect the reproductive system by decreasing sperm count, disrupting the menstrual cycle in women, and potentially impacting fertility in both men and women. Additionally, smoking marijuana may lead to decreased libido and sexual dysfunction.
No, only men do. That includes male-born transgendered persons who choose live as females and never get surgery to create a vagina.
Now a man born with female-to-male transsexualism who has this surgically corrected will have a penis analog that is created from the vaginal tissues and other grafts. However, it will not function in the same way as a genetic male's penis. Despite being born with a female body, this person has always been a male inside.
The term transsexual is only used for person who will eventually get surgery. The purpose of the surgery is to treat or cure the transsexualism and get rid of it. So after the surgery, the person is only called a man or a woman, depending on their social role and genitalia obtained. If someone is never going to get surgery, they are simply called transgendered. Often, a person is born with transsexualism and seeks to get rid of it and become a part of mainstream society, while transgenderism is often thought to be more of a choice and a type of LGBT behavior.
How does the female reproductive system work?
When females ae born they already have all of the eggs that they will produce in their lifetime: located in the OVARIES. Each month an egg is released.It travels through the FALLOPIAN TUBES and then goes to the UTERUS. If fertilization occures(sperm meets the egg) then the egg will attach to the UTEREAN WALL and a baby will form.
The female reproductive system is designed to carry out several functions. It produces the female egg cells necessary for reproduction, called the ova or oocytes. The system is designed to transport the ova to the site of fertilization. Conception, the fertilization of an egg by a sperm, normally occurs in the fallopian tubes. After conception, the uterus offers a safe and favorable environment for a baby to develop before it is time for it to make its way into the outside world. If fertilization does not take place, the system is designed to menstruate (the monthly shedding of the uterine lining). In addition, the female reproductive system produces female sex hormones that maintain the reproductive cycle.
During menopause the female reproductive system gradually stops making the female hormones necessary for the reproductive cycle to work. When the body no longer produces these hormones a woman is considered to be menopausal.
Is it possible to fertilize an ovum with another ovum?
No, it is not possible to fertilize an ovum with another ovum. In sexual reproduction, fertilization typically involves the fusion of a sperm cell with an ovum.
How many genes are ona human chromosome?
In recent study it has been found that there are about 20,000 to 25,000 genes in our genome.
Most of the sequences in our genome does not code for anything. Junk DNA or introns constitute about 90% of our genome.
What are reproductive cells called?
Reproductive cells are called gametes. In males, the gametes are called sperm and in females, the gametes are called eggs.
Whats the magor organs and tissues of the reproductive system?
The organs are...
(Female)
Ovary, Fallopian Tubes, Uterus, Cervix, and Vagina
(Male)
Scrotum, Testis, Epididymis, Vas Deferens, Seminal Vesicle, Prostate Gland, Urethra, Penis
And they have all four tissues
Muscular, Connective, Epithelial, and Nervous
What is the males reproductive cell called?
The male reproductive cell is called sperm. It is produced in the testes and is necessary for fertilizing the female egg to create offspring.
Whats the condition called where the earthworm has both female and male sex organs?
The condition is called hermaphroditism. In earthworms, hermaphroditism means possessing both male and female reproductive organs, allowing them to reproduce with any other earthworm.
What is the reproductive system of a monkey?
The reproductive system of a monkey is similar to that of other mammals. It includes organs such as the testes in males and the ovaries in females, as well as structures like the penis and vagina. Monkeys reproduce sexually through mating, leading to the fertilization of eggs by sperm.
