Anus :
Is muscles control bowel evacuation.
Appendix:
It is a vestige of man’s primitive past.
Bladder:
Acts as reservoir for urine which has been excreted by kidneys.
Bone marrow:

Kidneys:
Filters excretes and reabsorbs and thus helps to control balance of blood constituents.
Larynx:
Controls act of speaking.
Liver:

Pharynx:
Commonly called the throat, it is the passageway for food and drink and also for air which is breathed.
Pituitary gland:
A most important gland whose hormone secretions, directly or indirectly, control metabolism. It is responsible for growth and for proper thyroid, adrenal and ovarian gland function.
Prostate gland:
I secrets fluid in which sperm are transported during ejaculation.
Pylorus:
Its strong muscle fibres regulate outflow of stomach contents into duodenum.
Rectum:
It conveys stool toward outlet of intestinal truct.
Seminal vesicles:
Store semen for discharge through the ejaculatory ducts when orgasm takes place.
Spinal cord:
This structure contains the nerves which travel from and to the brain and thus are responsible for sensation and movements.
