Please do not include #2's information about glands removing things from the blood, because that is incorrect. (I believe he has confused glands with lymph nodes, which is a common mistake.) Glands are small organs which produce hormones and other special secretions. Endocrine glands release their secretions into the bloodstream, while exocrine glands release theirs onto a body surface either internally (the gastric glands that made stomach acid) , or externally (sweat glands).

Since you are working on hormones, you need to concentrate on the endocrine glands. You should read up a bit on them at this link. Endocrine glands are made up of specialized tissues that secrete various hormones and release them into the bloodstream. Hormones are chemicals that adjust the activity of specific cells in various areas of the body.

The endocrine system includes the pineal gland and the pituitary gland, which are at the base of the brain; the thyroid, which sits on top of the larynx; the thymus gland in the chest; the adrenals, which sit like a cap on top of each kidney, and the ovaries or testes. Every hormone you have studied comes from one of these glands, so you should go back over the material on hormones and try to match each on up with its endocrine gland.

Why don't you focus on how both hormones and glands need to be healthy for a healthy body. Research diseases that relate to hormone problems and gland problems, and perhaps you can also compare and contrast them. Sometimes seeing what happens when something is missing from our body best helps us understand what it does.

I believe your project refers to endocrcine glands. These produce hormone, chemical messengers which travel in the bloodstream to target organs and cause a response to occur. Hormones have long-lasting effects in the body. An example of a gland is the pituitary gland and one of its hormones is human growth hormone. The target organs are bones. This causes the bones to grow at puberty.

Glands are specialized cells which remove "things" from the blood in order for removal from the body or to be used in other ways by the body. Glands are defined as either exocrine or endocrine types.

Endocrine glands are present in the body whose purpose is to release hormones for specific tasks directly into blood stream (as they are ductless), to specific tissues and organs in order to make them exert their functions. Functions include growth, sexual process, reproduction, etc.

Where as hormones are the chemical messengers that are sectreted by endocrine glands, that travel throughout the body  to tissues and organs instructing them to carry out their functionsfunctions when the cells are affected.
