Q

which is brief, and which involves an increase in arousal.

A

Second stage is PLATEAU STAGE

25
Q

which involves waves of muscle spasms and pleasure that last several seconds. During this phase, the uterus has several contractions, and the penis has contractions at its base, causing semen, the fluid containing sperm, to ejaculate into the vagina.

The third phase is ORGASM

26
Q

during which the body relaxes to its original state.

A

The last stage is RESOLUTION

27
Q

In this process of reproduction, when semen is discharged in the vagina during sexual intercourse, the sperms begin moving up the vagina and uterus, finally reaching the FALLOPIAN TUBES. But only one sperm enters the ovum.

A

FERTILIZATION

28
Q

T or F
Most of the sperms die while climbing up the Fallopian tubes.

A

T

29
Q

A sperm can remain alive in the Fallopian tube for about 12 hours. In this span of time, if it meets the ovum, it is likely to enter the ovum. This is called?

A

fertilization

30
Q

In this process or reproduction, the ZYGOTE moves down the Fallopian tube and continuously undergoes cell division. Thus, it forms a hollow ball of cells, called EMBRYO.The embryo gets embedded in the wall of the uterus, which is thick and has muscles, glands and a large number of capillaries

A

Implantation

Q

A

THREE, PLACENTA

35
Q

38
Q

What is the total gestation period for an embryo to develop?

A

It is around 280 days, or 9 months, in humans.

39
Q

The wall of the uterus develops a thick layer of muscles during pregnancy. At the TIME OF BIRTH,the uterine muscles contract rhythmically and powerfully, causing labor pains to the mother. Finally, the baby is expelled by the contraction of the uterine muscles.

A

Birth “parturition”
