Human Reproduction Powerpoint Presentation

Major Structures and Functions

—Endocrine system:  it a glands network that contains glands such as testis, ovary, pancreas, adrenal gland, thymus, thyroid gland, pituitary gland and pineal gland. These glands secrete hormones which regulate a number of processes such as reproduction, metabolism, and growth in the body.

—Skeletal System:  it is a flexible, strong connective tissue and bones framework that provides body support and protection internal organs of the body.

—Muscular System: it contains muscles layers which cover skeleton bones and spread out across joints. These muscles layers cam relax and contract to enhance movement (Anatomy and Physiology, 2013).

—Reproductive System:  the male reproductive system contains the penis, urethra, vas deferens, and testis. The female reproductive system contains the vagina, uterus and ovary. Its function in both genders is to propagate the species via reproduction.

—Nervous System: It consists of two parts that include the peripheral nervous system and central nervous system. The central nervous system is created by a combination of  spinal cord and brain. The nerves transmit messages from and to the central nervous system to the peripheral nervous system or the entire body. The nervous system thus control all activities of the body

Diseases Risk Factors

—Men are more at the risk of getting cardiovascular and coronary heart diseases as compared to women.

—Women have a higher risk to blindness, osteoporosis, and osteoarthritis as compared to men

—Men are more probable to suffer from cancer apart from breast cancer that is more common to women than men

—Men are more probable to be diagnosed with tuberculosis as compared to women

—Women are more easily infected with STDs as compared to men.

—Women are more probable to get Alzheimer’s at old age as compared to men.

Male vs. Female body structure and function

—The obvious difference between male and female is the reproductive organs where men have a penis and testis and thus they are responsible of manufacturing sperms, while women have vagina and large breasts, and uterus and thus they are responsible of carrying pregnancy and lactating the kids.

—Men contain larger lungs and hearts, with high testosterone level and thus, they have a high production of red blood cells.  On the contrary women have larger appendix, liver, kidneys, and stomach, with their blood having a higher percentage of water. In this regard, men have a lower heart rate than women and they can manage more strenuous work for a long time without demanding extra oxygen as compared to women.

—An average man is heavier and taller as compared to average woman with stronger upper body as compared to women and thus, men can handle more demanding jobs than women.

—The brain of an average man contains about 100 grams of extra brain tissues and 4%extra cells as compared to brains of an average brains.

—Women has a high percentage of body fat as compared to men due to their role in reproduction (Heidi, 2014).

Structural difference

—Visible penis and testis for male, while women have vagina and large breast.

—Men are much taller and heavier as compared to women

—Women have longer truck, shorter legs, less protruding chin, broader face, and shorter head than men.  Women first finger is longer than the third while this is vice vasa on the man’s hand.

Sexual Reproduction and Development in Human

—Sexual reproduction is the fusion of unique haploid sex cells. It involves the fusion of egg and sperm cells in a process known as fertilization.

—Fertilization happens in the body of a woman when an egg moving down to the fallopian tube meets with a sperm. Fertilization results in the development of a diploid zygote in which a new person develops.

—The reproductive structures for both females and males contain 3 organization levels that include hormones secreting glands, transport tubes and sex cells production.

—The fertilized egg is embedded in the uterus lining around six to nine days after fertilization, amnion membrane develops around the it and later a placenta that attach the child to the mother develops in a period of three months (Leaving Bio, 2015).

—After fertilization, the ovum divides immediately into two cells. This division continues with each new cell dividing again to ensure the growth of a fetus immediately after fertilization to billions of cells that end up creating a grown child with all body structures.

—A fetus remain in the mother’s womb after fertilization for a period of 9 month where the child is born and normal growth continue through the same process of cell division.

—Fertilization  only takes place only when a man and a woman have unprotected sex and the women is in her fertile days of the menstrual cycle

—Unprotected sex can result to pregnancy or transmission of sexually transmitted diseases, if one partner is infected. This include HIV Aids, syphilis, and gonorrhea among others.

—However, all this can be prevented by applying protected sex  where a condom is applied.

Diseased State and Hemostasis

—Homeostasis is the static state of physiological systems of the body. It is maintenance of physical mechanisms of the body at a moderate stable condition in the internal environment of the body, irrespective of changes happening both outside and inside the body.

—The body internal environment in this case include chemical concentrations like particular hormones in the blood, PH, blood pressure, and body temperature, while possible changes include pregnancy, exercise, eating or external conditions variations.

—The homeostatic mechanisms of the body are managed mainly through the endocrine system and nervous system.

—On the contrary, a disease is a state of the body when a foreign material or body is trying to destroy the body functionality. It is a threat for harm which comes in different forms that include pathogens such as bacteria, viruses or genetic hereditary conditions.

—Disease is a malfunction or abnormality of some part of the body which is characterized by unique recognizable symptoms and signs (vIvyRose Holistic, 2015).
