If you are talking about periods, it is to dispose of the egg that was not fertilized. While it runs out, it gathers tissue with it.

because you have blood in your body and when you cut open yourself blood comes out (not necessarily cut yourself i mean in that way)
it's like a tube of ketchup, you cut it open and red stuff comes pourin out.
or it can be the time of the month.

because there is blood running through your entire body, piercing your skin or something could make you bleed and is the most common cause of it.

I require more elaborate explanations

Such as why blood comes out when you get a scar or something worse. I need you to explain it physically, and what blood consists of chemically to determine that something can float in it (i.e. argue that blood is a fluid).

And no, periods are small dots you put after your sentences, in order for things you write to make sense, because of you forget punctuation and connotation, your crap gets weird.

necessarily didn't say period
said time of the month
surely you can put that together as not at the end of a sentence (.) but seriously, common sense?

just research, c&g aren't full of doctors and everything.

You still have capillaries supplying blood to the skin cells. They are typically what are ruptured when you're cut or bruised.

Actually, I have a PhD in internet behavior analysis, and through studies similar to these, I would be able to tell you that your armpits are likely to smell.

Here's a better explanation, sir.

Blood is a bodily fluid in animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells.[1] When it reaches the lungs, gas exchange occurs when carbon dioxide is diffused out of the blood into the pulmonary alveoli and oxygen is diffused into the blood. This oxygenated blood is pumped to the left hand side of the heart in the pulmonary vein and enters the left atrium. From here it passes through the mitral valve, through the ventricle and taken all around the body by the aorta. Blood contains antibodies, nutrients, oxygen and much more to help the body work.[citation needed]

In vertebrates, it is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume),[2] and contains dissipated proteins, glucose, mineral ions, hormones, carbon dioxide (plasma being the main medium for excretory product transportation), and blood cells themselves. Albumin is the main protein in plasma, and it functions to regulate the colloidal osmotic pressure of blood. The blood cells are mainly red blood cells (also called RBCs or erythrocytes), white blood cells (also called WBCs or leukocytes) and platelets. The most abundant cells in vertebrate blood are red blood cells. These contain hemoglobin, an iron-containing protein, which facilitates oxygen transport by reversibly binding to this respiratory gas and greatly increasing its solubility in blood. In contrast, carbon dioxide is almost entirely transported extracellularly dissolved in plasma as bicarbonate ion.[citation needed]

Vertebrate blood is bright red when its haemoglobin is oxygenated and dark red when it is deoxygenated. Some animals, such as crustaceans and mollusks, use hemocyanin to carry oxygen, instead of hemoglobin. Insects and some mollusks use a fluid called hemolymph instead of blood, the difference being that hemolymph is not contained in a closed circulatory system. In most insects, this "blood" does not contain oxygen-carrying molecules such as hemoglobin because their bodies are small enough for their tracheal system to suffice for supplying oxygen.

Jawed vertebrates have an adaptive immune system, based largely on white blood cells. White blood cells help to resist infections and parasites. Platelets are important in the clotting of blood. Arthropods, using hemolymph, have hemocytes as part of their immune system.

Blood is circulated around the body through blood vessels by the pumping action of the heart. In animals with lungs, arterial blood carries oxygen from inhaled air to the tissues of the body, and venous blood carries carbon dioxide, a waste product of metabolism produced by cells, from the tissues to the lungs to be exhaled.

Medical terms related to blood often begin with hemo- or hemato- (also spelled haemo- and haemato-) from the Greek word αἷμα (haima) for "blood". In terms of anatomy and histology, blood is considered a specialized form of connective tissue, given its origin in the bones and the presence of potential molecular fibers in the form of fibrinogen.
