Sperm
Testes
In order, SPERM, TESTES, SCROTUM, EPIDIDYMIS, VAS DEFERENS, PENIS, SEMINAL VESICLE, PROSTATE, COWER'S GLAND, SEAMEN, ORGASUM, ERECTION, URETHRA, URINE, NOCTURNAL EMISSIONS.
Maturity occurs around 11-12 years of age. But the brain doesn't reach full maturity until 25.
Male humans don't have the same reproductive organs as females do. By the way this is by an 11 year old female.
11 or 12, I listed them below: 1). Skeletal 2). Circulatory (Cardiovascular) 3). Immune (Lymphatic) 4). Integumentary 5). Respiratory 6). Digestive 7). Endocrine 8). Excretory 9). Nervous 10). Muscular 11). Reproductive is broken into two: male and female but it's one system So 11 or (if you separate male and female reproductive) 12 organ systems :-)
Circulatory System (heart, blood, vessels) Respiratory System (nose, trachea, lungs) Immune System (many types of protein, cells, organs, tissues) Skeletal System (bones) Excretory System (lungs, large intestine, kidneys) Urinary System (bladder, kidneys) Muscular System (muscles) Endocrine System (glands) Digestive System (mouth, esophogus, stomach, intestines) Nervous System (brain, spinal cord, nerves) Reproductive System (male and female reproductive
1. Digestive System 2. Circulatory System 3. Respirator System 4. Skeletal System 5. Muscular System 6. Endocrine System 7. Immune System 8. Lymphatic System 9. Nervous System 10. Male Reproductive System 11. Urinary System 12. Excretory System 13. Cardiovascular System 14. integumentary system 15. Female Reproductive System
1. digestive system 2. excretory/urinary system 3. skeletal system 4. muscular system 5. respiratory system 6. cardiovascular/circulatory system 7. endocrine system 8. reproductive system 9. nervous system 10. immune system 11. integumentary system
There are 11, Respiratory System Digestive System or Excretory System Cardiovascular or Circulatory System Renal System or Urinary System Endocrine System Nervous System Muscular System Integumentary System or Exocrine System Lymphatic System or Immune System Reproductive System Skeletal system
when girls develop their reproductive system, or before periods. age 9 to 11, I'm sure.
The 11 body systems are as followed (not in order): the muscular,immune, skeletal, digestive, nervous, endocrine, circulatory, reproductive, integumentary, excretory, and the respitory system.
* circulatory system * digestive system * endocrine system * integumentary system * immune system * muscular system * nervous system * reproductive system * respiratory system There are actually more than nine. The ones not mentioned are: * skeletal system * excretory(urinary) system
The ovary is the female reproductive cell.And sperm is the male reproductive cell.-Samantha A. Agge : 12
