Who examined plant cells?

Who examined animal cells?

What is the statements in one of the basic principles of biology?

Levels of Biological Organization

What is Male Reproductive System?

What is Reproductive system?

Loose pouch-like sac of skin that hangs behind and below the penis Contains the testicles, as well as many nerve and blood vessels Acts as temperature regulation for the penis

Recognized as the male gonads A pair of oval organs that lie in the scrotum Responsible for making testosterone and for generating cells

Testes is secured at either end by a structure called?

The primary male sex hormone

Within the testes are coiled masses of tubes called? It is also the specific location of meiosis, and the subsequent creation of male gametes, namely spermatozoa

Long muscular tube that travels from the epididymis into the pelvic cavity, to just behind the bladder. Transports mature sperm from the epididymis to the urethra, the tube that carries urine or sperm outside of the body, in preparation for ejaculation.

It is a long, coiled tube that rest on the backside of each testicle Transport and stores sperm cells It nourish the sperm sperm to maturity, since the sperm which emerges from the testicle are immature and incapable of fertilization

Tube which carries the urine from the bladder to the outside of the body, and is also responsible of ejaculating semen when the man reaches orgasm

Sac-like pouches that attach to the vas deferens near the base of the bladder Produce a sugar-rich fluid (fructose) that provides sperm with a source of energy

The male organ used in sexual intercourse Holds the urethra, the tube that transports semen and urine

3 parts of penis a.) Atteches to the wall of the abdomen b.) Shaft C.) Cone shaped part of the end of the penis

Penis is covered with a loose layer of skin called?

It contains the sperm is ejaculated through the tip of the penis when the man reaches sexual climax (orgasm)

Responsible for the normal development of organs of the male reproductive system Brings about the changes experienced during puberty

Growth of facial, underarm, chest, pubic and body hair. Deepening of the voice. Development of male musculature and genitals. Increased secretion of sweat and oil.

it is responsible for male's muscular strength.

What is female reproductive system?

Recognized as the female gonads Small, oval-shaped glands that are located on either side of the uterus Responsible for the production of eggs cells and hormones, such as estrogen and progesterone

Narrow tube that attach to the upper part of the uterus and serve as a tunnels for the ova (egg cells) to travel from the ovaries to the uterus Site of conception or fertilization

The union of the egg and sperm cell is called?

Commonly referred to as the womb. A hollow, pear-shaped organs that is home to a developing fetus

what is the two parts of uterus?

(parts of uterus) it is located in the lower part that opens into the vagina; a channel through _____ allows sperm to enter and mentrual blood to exit.

(part of uterus) the main body of the uterus; expands during pregnancy to support a developing baby

The muscular, elastic tube or canal with soft , flexible lining that provides lubrication and sensation; joins the cervix (lower part of uterus) to he outside of the body Also know as the birth canal Reception of the penis and the semen during penetrative sexual intercourse

The outer vaginal opening is normally partly covered by a membrane called?

Responsible for female physical feature and reproduction Helps control the menstrual cycle and is important for chlidbirth Helps bring about the physical changes that turns a girl into a woman during puberty

Growth of the underarm and pubic hair. Breast development, wider hips, smaller waist Menstruation Increased secretion of sweat and oil

The process in which blood and other tissues are shed from the uterus and leave the body through vagina.

Is the monthly cycle of changes that happen in female reproductive system. It last roughly 28 day and begins at puberty.

What are the four main phases of menstrual cycle?

The egg from the previous cycle isn't fertilized Levels of the hormone estrogen and progesterone, drop (include the day of the phase) The uterus in this phase shed its inner lining of tissue and blood vessel which exits the body from the vagina in the form of menstrual fluid.

the following events occurs in this phase of menstruation: The hyphothalamus sends a signal to your pituary gland to secrete the egg cells in the ovaries to grow. One of these egg cells begins to mature in a sac-like structure called follicle It takes 13 days for the egg cells to reach maturity While the egg cell matures, its follicle secrete a hormone that stimbulates the uterus to develop a lining of blood vessels and soft tissue called the endometrium

(types of menstrual phase) Stimulates the process of the ovary releasing the mature egg.

(Mentrual Phase) (Include the day of the phase) The egg cell released during the ovulstion phase stays in the fallopian tube for 24 hours. If the egg cell is fertilized by the sperm cell, the fertilized egg will be implanted in the endometrium of the uterus. if the sperm cell does not impregnate the egg cell, the endometrium disintegrate leading to menstruation

What do you call to the first menstruation?

adult --> end It is the time that marks the end of your menstrual cycles.
