Food is a vital part of our life. Life is not possible without food. While food is very important in life, what is really important cannot be simply Food, but Healthy Food. Only when we plan what we eat, we can make sure we are running a healthy life.
We would have heard about saying like:

“An Apple a day keeps the Doctor Away”

“He who takes medicine and neglects to diet wastes the skill of his doctors”

and so on. These sayings insist on the importance of having the right kind of food. Only when we eat the right kind of food in the right amount at the right time, we can lead a healthy life. Only when we have a healthy food pattern every day we can lead a fresh routine on a daily basis.

We might be really wondering that though healthy food is important for a good life, is it possible to eat them alone always. Nowadays, we see a lot of junk foods in most of the restaurants. It is very human to start loving tasty food when compared to healthy food. But keeping ourselves strong towards making ourselves fit by having healthy food is a good habit.

WHAT DOES HEALTHY FOOD CONTAIN?
It might be difficult to accept eating healthy food that is bitter (or) sour (or) spicy. We might feel healthy food is not necessary on a daily basis. But, it is significant to understand that healthy food contains the right amount nutrients, vitamins, minerals and other essentials when had in the right proportion.

A balanced diet will help us to keep ourselves healthy always in life. Healthy Food not only give essential nutrients, but also generally:

Improve our concentration
Help in digestion
Improve Bowel Movements
Help children grow in a more healthy way
Prevent Aging
Avoid many serious illness and much more
WHAT DOES JUNK FOOD CONTAIN?
While healthy food are good in every means, eating junk food lacks all the essential nutrients. Once we eat Junk Food we might feel satisfied and full. But in reality, Junk Food gives us a sleepy feeling which is because the unwanted fat gets accumulated in the inner walls of arteries.

Also, it is very common and known that one of the major problem the world faces because of Junk Food is – Obesity. Studies also prove that even many school children are obese or overweight. Nowadays, school kids also prefer Junk Food over Healthy Food. Children are easily attracted by taste and colorful appearance of the Junk Food. Eating junk food namely:

Burger
Pizza
Wafers
Preserved or Canned Food and such other foods are totally unhealthy for the body. Over a period of time, this leads to serious illness and serious diseases. Children eating junk food often lack concentration. It is always good to restrict ourselves from eating Junk Food.

The Mesopotamian people transported their goods by carts, camels, boats off the river, and donkeys and horses. The good they transported where grain, textiles, and oil. They traded with Egypt, Phoenicians, and mostly between city-states. People got around by carts, camels, horse, boat, and donkey.

At sea-shore during the day cold air from the sea moves towards the beach because the land gets more heated than the sea water. Hot air above the land rises up, and cold air from the sea moves towards the land beach. This is called sea breeze as shown in Fig. (a).

During the night cold air from the land moves towards the sea because the land cools more quickly than the sea water. So hot air above the sea rises up and cold air from the land moves towards the sea. This is called land breeze as shown in Fig. (b).

The significant difference between them is the geographical area they cover. When we consider the order, PAN is capable of providing network connection around a person, next comes LAN which covers a smaller area; then comes MAN; it covers an area larger than LAN & WAN is the largest of all.

The organ's primary function is to secrete milk. Though it is present in both sexes, it is well developed in females and rudimentary in males. It is also a vital accessory organ of the female reproductive system.

The major parts of the digestive system:

• Salivary glands.
• Pharynx.
• Esophagus.
• Stomach.
• Small Intestine.
• Large Intestine.
• Rectum.
• Accessory digestive organs: liver, gallbladder, pancreas.

The placenta secretes hormones like human gonadotropins, human placental lactogen, oestrogen and progesterone that are necessary to maintain pregnancy. Due to the secretion of these hormones, it is called an endocrine gland.

The FSH secretion by the pituitary gland stimulates the ovarian follicles to secrete estrogen. Estrogen stimulates the proliferation of the endometrium of the uterine wall. After ovulation, the remaining cells of ovarian formed are stimulated by LH to develop corpus luteum which secrete a large amount of progesterone. Progesterone is essential for the maintenance of endometrium, for implantation of the fertilized ovum and other events of pregnancy.

During fertilization, the sperm and egg unite in one of the fallopian tubes to form a zygote. Then the zygote travels down the fallopian tube, where it becomes a morula. Once it reaches the uterus, the morula becomes a blastocyst. The blastocyst then burrows into the uterine lining — a process called implantation.

The process of germ cell development during spermatogenesis can be divided into five succesive stages: (1) spermatogonia, (2) primary spermatocytes, (3) secondary spermatocytes, (4) spermatids, and (5) spermatozoa.

Androgen, any of a group of hormones that primarily influence the growth and development of the male reproductive system. The predominant and most active androgen is testosterone, which is produced by the male testes.

FSH regulates the development, growth, pubertal maturation and reproductive processes of the human body. In both males and females, FSH stimulates the maturation of primordial germ cells. Follicle stimulating hormone is one of the hormones essential to pubertal development and the function of women's ovaries and men's testes. In women, this hormone stimulates the growth of ovarian follicles in the ovary before the release of an egg from one follicle at ovulation. It also increases oestradiol production.

Insulin helps control blood glucose levels by signaling the liver and muscle and fat cells to take in glucose from the blood. Insulin therefore helps cells to take in glucose to be used for energy. If the body has sufficient energy, insulin signals the liver to take up glucose and store it as glycogen.

Spermatogenesis is the process by which haploid spermatozoa develop from germ cells in the seminiferous tubules of the testis.  Thus, the primary spermatocyte gives rise to two cells, the secondary spermatocytes, and the two secondary spermatocytes by their subdivision produce four spermatozoa and four haploid cells.

The accessory glands of the male reproductive system are the seminal vesicles, prostate gland, and the bulbourethral glands. These glands secrete fluids that enter the urethra.

*******, in the male reproductive system, a thin external sac of skin that is divided into two compartments; each compartment contains one of the two testes, the glands that produce sperm, and one of the epididymides, where the sperm is stored.
