Testes
Penis
• There are two testes, located on the outside of the body within sac like structures called a scrotum, within the pelvic region, posterior to the penis and anterior to the anus. (David, 2014)
• The testes each weigh about 25 grams; they are 4 – 5cm in length and 2 – 3 cm in width.(David, 2014)
• The testes are covered by a fibrous capsule called tunica Albuginea (David, 2014).
• The Tunica is divided by fibrous tissues to form web shaped lobes. Each lobe is 3 to 10 coiled tubules called seminiferous tubules surrounded by connective tissue. (David, 2014)
• The penis has three parts: the root which is attached to the wall of the abdomen, the body or shaft and the glans. The glans is the head of the penis which is covered by a loose layer of skin called the foreskin.
The opening of the urethra is at the tip of the glans and is contained in the corpus spongiosum.
• The penis contains a number of sensitive nerve endings, lymphatic and blood vessels, also two suspensory ligaments made up of elastic fibers.
• The body of the penis is cylindrical in shape and consist of three internal chambers the corpus spongiosum,
• All three chambers are made up of sponge like erectile tissues called corpus cavernosa. They contain large spaces which fill with blood; the skin is loose and elastic.
• The erectile tissues are in tinny pools of blood vessels called cavernous sinuses.
• Each of these muscles are surrounded by smooth muscles and supported by elastic fibrous tissues, made up of protein called collagen.

The Uterus
• The uterus is a thick muscular organ located medial with abdomen. In an adult female the uterus is 7.5 cm long 5 cm wide and 2.5 cm thick before pregnancy. (Dr.Barbara,2014 )
• The more slender part of the uterus known as the cervix. The anterior part of the uterus body is known as the corpus uteri. This more circular. (Dr.Barbara,2014 )
• The uterus consists of three layers: the Myometrium, which forms most of the uterus muscular very firm and consist of densely packed unstripped smooth muscle fibers. The serous membrane , the outer layer which covers most of the uterus, then folds back to form the uterus ligament on each side. The endometrium the inner most membrane that lines the uterine cavity of the uterus. (Dr.Barbara,2014 )

The testes are the primary reproductive organs in the male; they are responsible for the production of sperm. The testes are responsible for the production of testosterone, and are almost nonexistent prior to puberty. Testosterone affects vary to the sound of your voice to hair baldness. The epididymis is a firm structure that consists of three parts, sperm that passes through the epididymis after they are formed. The male urethra is approximately 18-20 cm long. The urethra allows the passage of both urine and sperm. There are two main parts of the penis; the root and body. The three main parts of the root of the penis are, the midline bulb, and the left and right crura on either side of the bulb. While the body is formed by three cylindrical masses of erectile tissue, they are the corpus spongiosum in the midline, and the two-corpus cavernosa on either side. The urethra leaves the head of the penis at the end of the corpus spongiosum.
The penis consists of basically three cylinders, covered by several sheaths of tissue and, finally, by skin. A pair of corpora cavernosa form the erectile tissue that becomes engorged with blood during erection, acting like the inner tube of a tyre. They are surrounded by the tunica albuginea, a tough, inelastic, fibrous sheath, which might be compared with the tyre itself. When the penis becomes erect, the inner tubes (corpora cavernosa) inflate, filling the space within the tyre (tunica albugenia), making it more rigid.

Rectum is a chamber that contain around 8 inch of tube, the rectum are connected to the large intestine and anus. Rectum have a function of release the unnecessary product.
Here is where serous fluid is secreted by the pleural membranes lubricating the inside of the pleural cavity therefore stopping possible irritation to the lungs during respiration. The lung is shaped like a cone-shaped, the superior end of the lung that forms the point and the inferior end at the base. The apex is found at the superior end of the lungs. And the inferior end known as the base rests on the diaphragm. The base of the lungs is concave which follows the contour of the diaphragm.
The four tissue layers are the mucosa, submucosa, muscularis externa, and the serosa. The mucosa is the inner most layer which also composes of its own; the epithelial, lamina propia, and muscularis mucosa. The mucosa secretes hormones, digestive enzymes and also mucus as well. The submucosa is composed of areolar connective tissue, which contains a rich blood supply, nerve fibers and lymphatic vessels and follicles. The muscularis external is the layer that is responsible for the function of segmentation and peristalsis. It contains an inner circular layer and also an outer longitudinal layer both of smooth muscle cells. The serosa is the layer that is the outermost. It is also called the visceral peritoneum and it is areolar connective tissue that is covered with mesothelium.

Endometriosis is when the endometrial lining of the uterus bleeds and attaches to other organs and healthy tissues in the body. There is no one organ endometriosis favors it had been known to attach to the bladder, bowel, intestines and fallopian tubes. All though it has been found in the lungs and heart.

Epithelial tissue covers the surface of the human body and lines most internal cavities. Epithelial tissue is found in the body’s skin, lining of the stomach and intestines, the kidney, and glands, as well as other locations within the body (Amsel, 2012). The two types of epithelial tissue are (1) covering and lining epithelium and (2) glandular epithelium. The covering and lining epithelium are found lining the integumentary, digestive, cardiovascular, and respiratory systems as well as the ventral body cavity and the organs this cavity houses (Hoehn, et al., 2007, p. 118). The glandular epithelium is found within the glands of the entire human body. Not only are their two types of epithelial tissue found in the human body, there are also multiple classifications and various shapes. These classific...
The male reproductive system is a set of organs that works together to produce sperm which will later in life fertilize females eggs. The testes are the most important part of the system because it produces sperm cells. It is similar and looks similar to ovaries of a female’s reproductive system because it also holds what they need to reproduce. Its job is to produce the sperm cells needed to reproduce. Due to hormonal imbalances the production of sperm cells may not even be possible in some males. Testosterone is the male the hormone that gives men there manly characteristics. It is made up of hydrogen, carbon, and oxygen with a white color. In the male body it helps develop sex organs, a deeper voice, and facial hair (Khalid, 2013). Cancer or a genetic disorder in males is the most common thing that cause the reductions of testosterone production in the body. Behind the testes is the epididymis which lets sperm go through the vas deferens from the testes (Dictionary, 2014). It looks like leach the way it is position right on the testes but it is thinner. When sperm is produces the ...
...urpose is to clean the urethra of harmful bacteria and other substances prior to ejaculation. The penis, not composed of muscle or bone, is the next step for the sperm. It’s three main purposes are to transport urine, transport semen, and to provide sensation. Inside the penis is the urethra. The urethra’s functions are to carry urine from the bladder to outside the body, and to ejaculate semen during sexual intercourse. The tip of the penis is called the scrotum, and it’s three main functions are to act as a thermometer for the testicles, protect and hold the testicles, and to provide various sensations.
Dynamic equilibrium functions in the three semicircular ducts, the saccule and the utricle. The two ventical ducts are the anterior and posterior semicircular ducts. The lateral semicircular duct is horizontal. In the dilated portion of each duct, the ampulla, is a small elevation called the crista. This contains hair cells and supporting cells which are also covered by a mass of gelatinous material which is called cupula. When the head moves the attached semicircular ducts and hair cells move with it.
