Body System: Reproductive – Male The male reproductive system consists of several external organs (on the outside of the body) and internal organs (inside the body). An enlarged drawing and other diagrams are on page 2. Parts of the Reproductive System The major parts of the reproductive system are: Penis - the organ that urine and sperm (seminal fluid) go through to the outside of the body. Foreskin - a loose fold of skin covering the head of the penis. It may be removed during a surgical procedure called circumcision. Bladder Testicles (testes) - 2 walnut-sized organs that make sperm Prostate cells. The sperm unites with an egg from a woman for a baby Gland to begin. Penis Scrotum - the sac located on the outside below the penis that Urethra Scrotum holds the testes. Urethra - the tube that goes from the urinary bladder through Testicle the penis to the outside. Vas deferens - the tube that carries sperm from the testes to the urethra. Sperm move through the penis to the outside during ejaculation. Prostate gland - a gland that is inside the body at the base of the urethra. It secretes fluid that helps sperm move more easily. If you have any questions, be sure to ask your doctor or nurse.

This miracle is a characteristic that all living things have in common and sets them apart from nonliving things. But even though the reproductive system is essential to keeping a species alive, it is not essential to keeping an individual alive. In human reproduction, two kinds of sex cells or gametes are involved. Sperm, the male gamete, and an egg or ovum, the female gamete must meet in the female reproductive system to create a new individual. For reproduction to occur, both the female and male reproductive systems are essential. While both the female and male reproductive systems are involved with producing, nourishing and transporting either the egg or sperm, they are different in shape and structure. The male has reproductive organs, or genitals, that are both inside and outside the pelvis, while the female has reproductive organs entirely within the pelvis. The male reproductive system consists of the testes and a series of ducts and glands. Sperm are produced in the testes and are transported through the reproductive ducts. These ducts include the epididymis, ductus deferens, ejaculatory duct and urethra. The reproductive glands produce secretions that become part of semen, the fluid that is ejaculated from the urethra. These glands include the seminal vesicles, prostate gland, and bulbourethral glands.

The Reproductive System Main Idea Males and Females Have Different Reproductive Structures and Functions
Regulation and Human reproduction and growth and development involve the interactions of all body systems. Reproduction SECTION 1 The Endocrine System Main Idea Hormones from endocrine glands affect many body functions including reproduction. SECTION 2 The Reproductive System Main Idea Males and females have different reproductive structures and functions. SECTION 3 Human Life Stages Main Idea Before birth and until death, a human changes continuously. Where’s the emergency? This fire station control room has panels of blinking buttons and monitors. Dispatchers can access and relay emergency information quickly using this complex monitoring system. In a similar way, your body’s endocrine system monitors and controls the actions of many of your body’s functions.

Male Reproductive Anatomy
Male Reproductive Anatomy Words To Know: Testosterone: Male hormone. Causes hair growth, deeper voice, sperm production. Bladder: Organ that holds urine until excreted from the body. Testicle / Testes: Male organ that produces the sperm. 100 million sperm produced a day. The testes are developed high in the body and nerve endings are still there. Sperm Cells: Male reproductive cell produced in the testes. Scrotum: This is a sac that regulates the temperature of the testes. Keeps temperature at 95℉ and will rise closer to the body (to get warmer, use body heat) and lower (cool down) to help with this. Epididymis: Sperm is stored here. Can hold sperm for 6 weeks or until mature. Vas Deferens: A tube that travels from the epididymis to the urethra. Sperm travel along this tube. Seminal Vesicle: This vesicle adds a sugary fluid to the semen. Prostate Gland: This gland adds a chemical fluid to the semen. Cowper’s Gland: Secretes a fluid that helps make the environment safer for the sperm. Urethra: Brings urine and semen out of the body. Penis: Is made up of a spongy tissue. Erection: When the penis becomes engorged with blood and hard. Semen: Fluid ejaculated from the penis. Six Ways to Care for the Male Reproductive System! 1. Choose Abstinence. Abstinence is choosing not to be sexually active. Choosing abstinence prevents infection with sexually transmitted diseases. It also keeps you from becoming a teen father. 2. Have Regular Medical Checkups. Your physician can examine you and discuss body changes. 3. Bathe or Shower Daily. Keep your external reproductive organs clean.

Day 6 Urogenital System
Day 6 Urogenital System: Urinary System The structures of the reproductive and urinary systems are often considered together as the urogenital systems, since they have common embryological origins. However, the emphasis in this dissection is on identifying the structures of the urinary tract with only a few references to contiguous reproductive structures. The anatomy of the reproductive system is studied in the next section. Identifying Organs of the Urinary System 1. Obtain your dissection specimen and place it on your dissection tray. Reflect the abdominal viscera (most importantly the small intestine) to locate the kidneys high on the dorsal body wall. Note that the kidneys in the cat, as well as in the human are retroperitoneal (behind the peritoneum). 2. Carefully remove the peritoneum, and clear away the bed of fat that invests the kidneys. Then locate the adrenal (suprarenal) glands that lie superiorly and medial to the kidneys. 3. Identify the renal artery (red latex injected), the renal vein (blue latex injected), and the ureter at the hilus region of the kidney. (You may find two renal veins leaving one kidney in the cat but not in humans). 4. Trace the ureters to the urinary bladder, a smooth muscular sac located superiorly to the small intestine. If your cat is a female, be careful not to confuse the ureters with the urine tubes, which lie superior to the bladder in the same general region. See Figure D8.1. Observe the sites where the ureters enter the bladder. How would you describe the entrance point anatomically? 5. Cut through the bladder wall, and examine the region of the uretheral exit to see if you can discern any evidence of the internal sphincter.
