B. testes - the Sertoli cells of the Testes are where sperm mature and the Leydig cells of the Testes generate Testosterone
The vas deferens is a delivery tube connecting the testes to the prostate/urethra for export, and the penis is only a conduit to deliver the sperm inside semen during coitus.
The epididymis only stores mature sperm in preparation for the next ejaculation.
Smoking cigarettes will kill you, but before you die, you could experience some pretty terrible diseases and health conditions from smoking. Here are some of the most gruesome diseases caused by smoking
1. lung cancer: More people die from lung cancer than any other type of cancer. Cigarette smoking is the number one risk factor for lung cancer; it's responsible for 87 percent of lung cancer deaths. Your chance of still being alive five years after being diagnosed is less than 1 in 5.
2. COPD (chronic obstructive pulmonary disease): COPD is an obstructive lung disease that makes it hard to breathe. It causes serious long-term disability and early death. COPD starts by making it hard to be active, such as playing with a grandchild, then usually gets worse, until climbing a short set of stairs or even walking to get the mail is exhausting or impossible. It can leave people stuck in their homes, unable to do the things they want or see friends. About 80 percent of all COPD is caused by cigarette smoking. COPD is the third leading cause of death in the United States.
3. Heart Disease: Smoking harms nearly every organ in your body, including your heart. Smoking can cause blockages and narrowing in your arteries, which means less blood and oxygen flow to your heart. When cigarette consumption in the U.S. decreased, so did the rates of heart disease. Yet, heart disease still remains the number one cause of death in the U.S.
4. stroke: Because smoking affects your arteries, it can trigger stroke. A stroke happens when the blood supply to your brain is temporarily blocked. Brain cells are deprived of oxygen and start to die. A stroke can cause paralysis, slurred speech, altered brain function and death. Stroke is the fourth leading cause of death in the United States and a leading cause of adult disability.
5. Asthma: Asthma is a chronic lung disease that makes it harder to move air in and out of your lungs—otherwise known as "breathing." Because cigarette smoke irritates air passages, it can trigger sudden and severe asthma attacks. Asthma is a serious health condition that affects more than 26 million Americans. Smoking only makes it worse.
