The clot grows. Proteins in your blood called clotting factors signal each other to cause a rapid chain reaction. It ends with a dissolved substance in your blood turning into long strands of fibrin. These get tangled up with the platelets in the plug to create a net that traps even more platelets and cells.
The Male Reproductive System The main role of the male reproductive system is to make and deliver sperm. The testes are the main organs of the male system. Two testes are held in an external sac called the scrotum. The testes make sperm in tiny tubes called seminiferous tubules.The sperm mature and are stored in an epididymis. A tube called a vas deferens carries sperm from each testis to the urethra within the penis.Along the way, secretions of several glands form a nutrient-rich fluid called seminal fluid.he sperm mature and are stored in an epididymis.

1 Thecal sac refers to the the sac which is a membrane (called dura mater) that contains the spinal cord and cerebrospinal fluid. 2  All this statement implies is that the disc bulge is contacting the membrane that contains the spinal cord.  3 minimal narrowing of the neuro foramina - probably you meant neural foramina. At each level in the spine where there is a disc, right and left nerve roots come out to innervate tissues in the body. 2  The holes that they come out are called neural foramina. 3  This statement means that the size, or diameter, of those holes has been minimally narrowed by this diffuse disc bulge.
