**Follow up: the lymphatic vessels of the testes terminate in the lateral and preaortic sets of lumbar nodes. Source: Gray's Anatomy.\n\nThe lymph nodes in the groin or inguinal region drain the penis and testicles.\n\nIf you have swelling in any area that you suspect is a lymph node, you should have a physician check it immediately. There are a variety of infections that can cause a lymph node to swell, but this could also be a symptom of lymphoma - cancer of the lymph nodes. \n\nGood luck - it isn't fun to have a lump near the "boys".

That would be calcium phosphate.  It has a very high compressive strength.

Lymph nodes are any of numerous oval bodies, distributed throughout the lymphatic system, that produce and house lymphocytes (white blood cells formed in lymphatic tissue) and filter microorganisms and other particles from lymph. \nThey are a defense mechanism of the body against infection and disease.

Hmmm, good question.  I guess I automatically assumed capillaries, but they might not be small enough to be considered capillaries.  On second thought, I'd go with arterioles because these vessels have oxygenated blood in them (meaning they came from the heart), are too small to be arteries but not small enough to be capillaries, and are obviously not viens.

Lymph nodes are like  filters the body uses to rid it self of infections . They are  filled with leucocytes (white cells) which gather bacteria and viruses and then destroy them. So when this are working  they swell and become tender .

The circulatory system absorbs the stuff you eat once it's broken down.  The lymphatic system helps protect you from bad stuff you've eaten.

The Cardiovascular System\n\n\n The cardiovascular system and the lymphatic system form what is collectively called the circulatory system. Together, these systems transport oxygen, nutrients, cell wastes, hormones, and many other substances to and from all cells in the body. The trillions of cells in the human body take up nutrients and excrete wastes every minute of every day. Although the pace of this exchange may increase with activity or slow with rest, it happens continuously. If it stops, so does life. Of the two systems, the cardiovascular system is the primary transport operator; the lymphatic system aids it in its function.\n\n\nDesign: Parts of the Cardiovascular System\n\nCardiovascular comes from the Greek word cardia, meaning "heart," and the Latin vasculum, meaning "small vessel." The basic components of the cardiovascular system are the heart, the blood vessels, and the blood. The system can be compared to a large muscular pump (the heart) that sends a fluid (blood) through a series of large and small tubes (blood vessels). As blood circulates through the increasingly intricate system of vessels, it picks up oxygen from the lungs, nutrients from the small intestine, and .....

Ah ha.  Thermite.  Magnesium ribbon would be the usual method to start this reaction.\n\nBe careful with this reaction...

The outermost layer is known as the tunica adventitia or the adventitia, and is composed of connective tissue. Inside this layer is the tunica media, or media, which is made up of smooth muscle cells and elastic tissue. The innermost layer, which is in direct contact with the flow of blood is the tunica intima, commonly called the intima. This layer is made up of mainly endothelial cells. The hollow internal cavity in which the blood flows is called the lumen.

Salt - sodium chloride.\n\nIf you need something a bit more unusual, I believe there is imitation salt which is potassium chloride.
