PACITA COMPLEX NATIONAL HIGH SCHOOL SY 2020-2021 GRADE 10 WEEK 1 – 2 Introductory Reading on Reproductive System The system involved in sexual reproduction is called the reproductive system. There is a striking difference between the male and female reproductive systems, although they also share a number of similarities. For example, the reproductive organs of the male and female are developed from the same embryological structures, and some hormones are commonly found in both male and female, in varying quantities and produce different responses. The Male Reproductive System Parts of the Male Reproductive System 1.Add the following labels to the diagram of the reproductive system of a male dog shown below. Write your answer in your answer sheet. Penis, vas deferens, urethra, bladder, rectum, prostate gland, ureter, testes, seminal vesicle, epididymis Science Department | Grade 10 1 PACITA COMPLEX NATIONAL HIGH SCHOOL SY 2020-2021 2.Fill in the table using the choices in the list below.

Label the structures in the diagram with letters A to E as described. A. Seminiferous tubules in which the sperm are made. B. Collecting ducts where the sperm are stored. C. Epididymis in which sperm mature and become motile. D. Fibrous coat surrounding and protecting the testis. E. Vas deferens or sperm duct.

Directions: For each body part, do the following: Copy the body parts in your answer sheet. Write “M” if the part is found in people who were born male. Write “F” if the part is only found in females. Write both “M” and “F” if they are found in people of all sexes. Write “1” if most Science Department | Grade 10 5 PACITA COMPLEX NATIONAL HIGH SCHOOL SY 2020-2021 people have one of that part. Write “2” if most people have two. The first one is done for you as an example. Answer the questions below. The answers are not on the list above. Spelling counts. A. What is the common word for spermatazoa? _______________________ B.

What is the medical word for “period”? _______________________ E. What is the medical term for “wet dream”? _______________ The Endocrine System The endocrine system is composed of glands that secrete different types of hormones that affect almost every cell, organ, and function of our body. It is essential in regulating growth and development, metabolism, as well as reproductive processes and mood. Endocrine glands secrete chemicals known as hormones into the bloodstream, which carries them throughout the body. When hormone in the blood reaches the target organ, it produces a notable effect. The endocrine system sends signals all over the body, much like nervous system, but unlike the instant responses activated by the nervous system, the effects can take a few hours or even weeks. Endocrine Glands and Their Hormones The endocrine system contains a group of glands that release hormones into the body. The following table lists all the major glands in the body, with their functions, locations, and the hormones they release.
