Amenorrhea

Amenorrhea means no menstruation. It’s normally before puberty, during pregnancy and lactation and after menopause. Sometimes though menstruation either never starts which is called primary amenorrhea or suddenly stops in a person who's previously menstruating which is called secondary amenorrhea . The menstrual cycle as a whole are controlled by the hypothalamus and the pituitary gland all the way up in the brain. The hypothalamus secretes gonadotropin releasing hormone or GnRH which makes the nearby anterior pituitary gland release follicle stimulating hormone or FSH and luteinizing hormone or LH in the first two weeks of an average 28-day cycle. The ovaries go through the follicular phase meaning that out of the many follicles scattered throughout the ovaries a couple of them enter a race to become the dominant follicle that will be released at ovulation. All the developing follicles secrete loads of oestrogen which negatively inhibits pituitary FSH. In the meantime the ute...

A short note on human digestive system

The digestive system is the collective name used to describe the alimentary canal, some accessory organs and a variety of digestive processes which take place at different levels in the canal to prepare food eaten in the diet for absorption. The alimentary canal begins at the mouth, passes through the thorax, abdomen and pelvis and ends at the anus. It has a general structure which is modified at different levels to provide for the processes occurring at each level. The complex of digestive processes gradually breaks down the foods eaten until they are in a form suitable for absorption. For example, meat, even when cooked, is chemically too complex to be absorbed from the alimentary canal. It therefore goes through a series of changes which release its constituent nutrients: amino acids, mineral salts, fat and vitamins. Chemical substances or enzymes which effect these changes are secreted into the canal by specialised glands, some of which are in the walls of the canal and some outsid...

A short note on Blood

BLOOD Blood is a connective tissue. It provides one of the means of communication between the cells of different parts of the body and the external environment, e.g. it carries: • Oxygen from the lungs to the tissues and carbon dioxide from the tissues to the lungs for excretion • Nutrients from the alimentary tract to the tissues and cell wastes to the excretory organs, principally the kidneys • Hormones secreted by endocrine glands to their target glands and tissues • Heat produced in active tissues to other less active tissues • Protective substances, e.g. antibodies, to areas of infection • clotting factors that coagulate blood, minimising its loss from ruptured blood vessels. Blood makes up about 7% of body weight (about 5.6 litres in a 70 kg man). This proportion is less in women and considerably greater in children, gradually decreasing until the adult level is reached. Blood in the blood vessels is always in motion. The continual flow maintains a fairly consta...
