The Reproductive system Biology - The Reproductive system

In female, after how much time after fertilization, does the fertilized egg get implanted in the uterine wall?

The sperm is a specialised cell designed for the purpose of (i) ___________ It consists of a head, which contains the (ii) ___________ a midpiece packed with (iii) ___________ to provide energy, and a long (iv) ___________ that propels the sperm towards the egg. During (v) ___________ the sperm merges with the egg, leading to the formation of a zygote.

The human female gonads are ovaries. A maturing egg in the ovary is present in a sac of cells called ___________(i). As the egg grows larger, the follicle enlarges and gets filled with a fluid and is now called the ___________ (ii) follicle. The process of releasing the egg from the ovary is called ___________ (iii). The ovum is picked up by the oviduct funnel and fertilisation takes place in the ___________ (iv). In about a week, the blastocyst gets fixed in the endometrium of the uterus and this process is called ___________ (v).

The period of complete development of the foetus till birth is termed as ___________ .

___________ is the innermost membrane that closely covers the embryo when first formed.

Placenta is ___________ permeable.

What happens to the uterus, if fertilization fails to take place?

Given below is a portion of the diagram to show the diagrammatic highly magnified view of a single human sperm. Complete the diagram to show its normal structure.

Given below is the schematic diagram of the sectional view of the human male reproductive system.
State the functions of the parts numbered 1, 2, 3, 5, 8 and 11.

Given below is the schematic diagram of the sectional view of the human male reproductive system.

Name the parts numbered 1-11.

The following diagram represents the vertical sectional view of the human female reproductive system.

Label the parts indicated by the guidelines 1 to 8.

Given below is a diagram of two systems together in the human body.
Describe the functions of the parts 3, 4, 5 and 6.

Match the items in column I with those in column II and write down the matching pairs (some may not match)

	Column I		Column II
a	Acrosome	1	An embryo which looks likehuman baby
b	Gestation	2	Luteinizing hormone
c	Menopause	3	ovum producing cells
d	Foetus	4	complete stoppage of menstrualcycle
e	Oogenesis	5	spermatozoa
f	Ovulation	6	Complete stoppage of menstrualcycle.
		7	Time taken by a fertilized egg tillthe delivery of baby

 

Given below is the outline of the male reproductive system. Name the parts labelled 1 to 8 and state their functions. Also name the corresponding structure of part (4) in the female reproductive system.

Name and describe very briefly the stages in the development of human embryo.

Gestation period in humans is about 380 days.

Nutrition and oxygen diffuse from the mother’s blood into the foetus’s blood through amnion.

Uterus is also known as birth canal.

Fertilisation occurs in vagina.

The protective sac which develops around the developing embryo is called the pericardium.
