UNIT III-LESSON 2: BODILY CHANGES THAT OCCUR IN MALES AND FEMALES DURING PUBERTY WEEK 2 (OCTOBER 13-17) OBJECTIVES oDescribe the changes that happen during puberty.  PUBERTY Is the time when your body starts to change from that of a child to that of an adult. During puberty, many changes occur in physical traits, personality, and behavior. You may sometimes feel very conscious about these changes. CHANGES THAT OCCUR DURING PUBERTY FOR BOYS AND GIRLS  Growth Spurt – Sudden increase in height which usually lasts for two to three years.  Bone Growth – growth of bones and muscles during puberty  Changes in Weight – Adolescent girls develop a greater part of body fat than boys. While boys also have an increase in the growth of body fat, their muscle growth is faster. PHYSICAL CHANGES FOR BOYS His voice becomes deeper due to the growth of the larynx. Hair starts to grow under his armpits and around his genitals. His chest and shoulders become broader. Some experience slight breast development but is usually temporary and disappears after a while. PHYSICAL CHANGES FOR GIRLS  Her breasts begin to develop.  Hair begins to grow under her armpits and around her genitals.  The tone of her voice becomes higher and her skin becomes finer.  When menstruation starts, her hips will get wider and her waist will get smaller. She grows fast in height and starts to build up fat in her stomach and legs. UNIT III-LESSON 2: BODILY CHANGES THAT OCCUR IN MALES AND FEMALES DURING PUBERTY WEEK 2 (OCTOBER 13-17) OBJECTIVES oDescribe the changes that happen during puberty. CONDITIONS OR CONCERNS ASSOCIATED TO PUBERTY  Acne – inflammation of the sebaceous glands and hair follicles of the skin. During puberty, the skin gets oilier and they may start to sweat more which then makes them prone to acne.  Scoliosis – abnormal curvature of the spine. It can be worsened or apparent during puberty due to rapid growth.  Vision changes – Have a high incidence during puberty because of growth in the axial diameter of the eye. PROPER ATTITUDE TOWARD CHANGES UNIT III-LESSON 3: THE MENSTRUAL CYCLE WEEK 2 (OCTOBER 13-17, 2024) OBJECTIVES o Explain the menstrual cycle. o Relate the menstrual cycle in females and semen production in males to the ability to reproduce. o Reflect critically on learning experiences and processes in growing up.  MENSTRUAL CYCLE Menstruation is a part of the menstrual cycle. The cycle is the process that prepares a woman for pregnancy. The cycle repeats itself every 28 days (on average) during the reproductive years of most women.  MENSTRUAL CYCLE It is the time from the first day of a woman’s period to the first day of her next period. The average menstrual cycle is 28 days long. Cycles can range anywhere from 21 to 35 days in adults and 21 to 45 days in young teens. PHASES OF MENSTRUAL CYCLE  THE MENSTRUAL PHASE A woman’s monthly bleeding is commonly referred to as a period. It usually lasts for 3 to 7 days. The first day of menstrual cycle is your first day of menstruation. This is the time when you have cramping abdominal pains caused by the contraction of the uterine and the abdominal muscles that help in expelling the menstrual fluid.  THE FOLLICULAR PHASE  The lining of the uterus starts to grow or proliferate due to estrogen.  Follicle-stimulating hormone (FSH), increases and in turn, stimulates the growth of ovarian follicles that contain an egg.  Menstrual bleeding stops as the estrogen level increases.  The pituitary gland releases a hormone that travels to the ovaries and causes the most mature egg to be released.  THE OVULATION PHASE  Ovulation is when your ovary releases a mature egg (ovum).  The only phase in the menstrual cycle is when you have a high chance of getting pregnant.  If you have a regular 28-day cycle, ovulation usually starts on the 14th day.  It takes about 3 to 4 days for the egg to travel toward the uterus. If fertilization is to occur, it must happen within 24 hours of ovulation or the egg will die.  THE LUTEAL PHASE  The follicle develops into a hormone-producing structure called the corpus luteum which produces estrogen and a high amount of progesterone.  The hormone signals the uterus to thicken to provide nutrients for the coming baby in case a sperm fertilizes the egg.  If the egg cell is not fertilized, the thickening of the uterus breaks down and comes out of the body through menstruation. PHASES OF MENSTRUAL CYCLE UNIT III-LESSON 3: THE MENSTRUAL CYCLE WEEK 2 (OCTOBER 13-17, 2024) OBJECTIVES o Explain the menstrual cycle. o Relate the menstrual cycle in females and semen production in males to the ability to reproduce. o Reflect critically on learning experiences and processes in growing up. HOW FERTILIZATION TAKES PLACE? When a sperm cell unites with an ovum, the ovum becomes fertilized and a new life begins. This is the process known as fertilization. After a sperm cell and an ovum unite to form a fertilized egg or zygote, the fertilized egg will grow and develop in the uterus for about nine months.  PROBLEMS THAT OCCUR DURING MENSTRUATION Premenstrual Stress or PMS – before the period, women may experience problems like headache, irritability, nervousness, fatigue, crying spells, and depression with no apparent cause. Dysmenorrhea – also known as menstrual cramps. Amenorrhea – lack of menstrual period. It is not normal and healthy when you miss a menstrual period.
