DISEASES AND ILLNESSES 




Infectious and noninfectious diseases

Infectious diseases, such as common colds, are caused by harmful organisms called pathogens entering our body.

Examples Different kinds of pathogens cause different kinds of diseases. Here are some example diseases caused by each type of pathogen: Viruses - Viruses are extremely small and consists of DNA with a protective coating of protein. Diseases caused by viruses include influenza, the common cold, measles, yellow fever, and hepatitis. Bacteria - Bacteria are small microorganisms. They can cause diseases such as tuberculosis, cholera, typhoid fever, and tetanus. Parasites - Parasites are organisms that live off their hosts. Some parasitic diseases include malaria, sleeping sickness, and scabies. Fungi - Fungi are microorganisms such as yeasts and molds. They can cause diseases such as fungal meningitis, ringworm, and thrush.

The most common pathogens are bacteria and viruses. Other microorganisms, such as some kinds of fungi and protists, can also cause diseases.

Non-infectious diseases, such as diabetes, are not caused by organisms. They are caused by different factors and cannot be spread from person to person.

 A healthy lifestyle helps prevent diseases. This includes a healthy diet, exercise, regular check-ups, and saying no to drugs and alcohol and an excessive use of video games.

ADVANCES IN MEDICINE



One way of developing immunity to some infectious diseases is through vaccination.

 Doctors and physicians use a variety of diagnostic techniques to identify an illness, such as X-rays, electrocardiographs, blood tests, ultrasound scans and CT scans.

 

 There have been lots of scientific advances in the treatment of illnesses, such as antibiotics, which are used to treat infections caused by bacteria. 

 

Since the invention of anaesthesia in 1800, there have been lots of advances in surgery and in other medical fields.

6º. Unit 3 .REPRODUCTION.

6º. Unit 3.REPRODUCTION
The miracle of life
 Like other living things, human beings reproduce. It's what keeps the population going. In humans, the male and female reproductive systems work together to make a baby.

Fertilisation

During sexual intercourse the man's penis releases semen into the woman's vagina. Sperm cells travel in semen from the penis and into the top of the vagina. They enter the uterus through the cervix and travel to the egg tubes. If a sperm cell meets with an egg cell there, fertilisation can happen. Fertilisation happens when an egg cell meets with a sperm cell and joins with it.
The fertilised egg divides to form a ball of cells called an embryo. This attaches to the lining of the uterus and begins to develop into a foetus (pronounced "fee-tuss") and finally a baby.

Female Reproductive System

Ovaries

The two ovaries contain hundreds of undeveloped female sex cells called egg cells or ova. Women have these cells in their bodies from birth - whereas men produce new sperm continually.

Egg tubes

Each ovary is connected to the uterus by an egg tube. This is sometimes called an oviduct or Fallopian tube. The egg tube is lined with cilia, which are tiny hairs on cells. Every month, an egg develops and becomes mature, and is released from an ovary. The cilia waft the egg along inside the egg tube and into the uterus.

Uterus and cervix

The uterus is also called the womb. It is a muscular bag with a soft lining. The uterus is where a baby develops until its birth.
The cervix is a ring of muscle at the lower end of the uterus. It keeps the baby in place while the woman is pregnant.

Vagina

The vagina is a muscular tube that leads from the cervix to the outside of the woman's body. A man's penis goes into the woman's vagina during sexual intercourse. The opening to the vagina has folds of skin called labia that meet to form a vulva. The urethra also opens into the vulva, but it is separate from the vagina, and is used for passing urine from the body.

Male Reproductive System

About the Male Reproductive System

Most species have two sexes: male and female. Each sex has its own unique reproductive system. They are different in shape and structure, but both are specifically designed to produce, nourish, and transport either the egg or sperm.
Unlike the female, whose sex organs are located entirely within the pelvis, the male has reproductive organs, or genitals, that are both inside and outside the pelvis. The male genitals include:
  • the testicles
  • the duct system, which is made up of the epididymis and the vas deferens
  • the accessory glands, which include the seminal vesicles and prostate gland
  • the penis

Testes

The two testes (one of them is called a testis) are contained in a bag of skin called the scrotum. They have two functions:
  • to produce millions of male sex cells called sperm
  • to make male sex hormones, which affect the way a man's body develops.

Sperm duct and glands

The sperm pass through the sperm ducts, and mix with fluids produced by the glands. The fluids provide the sperm cells with nutrients. The mixture of sperm and fluids is called semen.

Penis and urethra

The penis has two functions:
  • to pass urine out of the man's body
  • to pass semen into the vagina of a woman during sexual intercourse.
The urethra is the tube inside the penis that can carry urine or semen. A ring of muscle makes sure that there is no chance of urine and semen getting mixed up.
