Yes they do.
Oxygen goes from the lungs to the tissues via the blood stream and CO2 goes back to the lungs via the blood stream

The lymphatic system is closely associated with the cardiovascular system. The primary organs of the lymphatic system are the bone marrow and thymus gland, and the secondary lymphatic organs include the lymph nodes and spleen. These organs work together to transport excess tissue (interstitial) fluid back to the blood stream, transport dietary fat, and help defend the body against disease causing agents. I would consider it more of the recycling system than a drainage system. The urinary system fits that description better since you are getting rid of wastes instead of recycling fluids.
The normal cycle of the circulatory system involves the arteries which carry blood away from the heart. Veins carry the deoxygenated blood back to the heart. In addition, there is the lymphatic system which is a one-way drainage system that transports interstitial fluid back into the blood stream.
In the case of multi-cellular organisms such as human beings, cells receive food by way of the blood, which carries nutrients to them, which they then absorb through their cell membranes.
The term used for excess fluid in tissues is edema. The more complete name is lymphedema and is usually the result of the lymphatic system not being able to move lymphatic fluid from tissues back into the blood stream, which results in the 'bloating' associated with it.
The lymphatic system picks up fluid leaked from blood vessels and returns it to the blood; disposes of debris in the lymphatic stream; and houses white blood cells involved in immunity.
They probably have to remember where they were born.

Lymph is a fluid. It flows through the lymphatic vessels by one way valves which allows lymph move way through lymphatic system. Subclavian suction, and skeletal muscle pumps help to propel the lymph through the lymphatic vessels.
Lymph cisterna chyli has a conduit for the product of digestion while the general lymphatic stream gets intersistual fluids and white blood cells and goes through the lymph nodes to be cleaned before being sent back to the blood.
Yes, all hormones are released into the blood stream and then circulate to all tissues; only those target tissues that are designed to react to specific hormones will react to the presence of the hormone. Hormones are chemical messengers that are released into the blood stream, designed to cause changes in only certain tissues.

Lacteals are lymphatic vessels found in small intestinal villi. While other nutrients such as amino acids and saccharides are absorbed into the blood stream, lacteals and the lymphatic system are used to absorb fats.
Meanders are created in the stream bed when a shallow graded stream cuts from side to side in its erosion process.It will create cliffs on the outside of the bends, and smooth banks on the inside of the stream. These features will migrate upstream.
Oxygen goes from the lungs to the tissues via the blood stream and CO2 goes back to the lungs via the blood stream
once any cancer metastasizes it can spread anywhere, including the colon, via the blood stream or lymphatic system.
