Yes, lymphocytes travel in both the bloodstream and the lymphatic system. They are produced in the bone marrow and circulate through the bloodstream to reach different tissues. They can also enter the lymphatic system to move between lymph nodes and lymphoid tissues.
Lacteals collect fats by absorbing chylomicrons (consisting of 90% triglycerides, 5% cholesterol, 4% phospholipids, 1% protein) in the small intestines and transports them to cardiovascular circulation. Chylomicrons travel through the lymphatic system via the thoracic duct to the bloodstream.
The cardiovascular system circulates blood throughout the body, delivering nutrients and oxygen to cells. The lymphatic system helps maintain fluid balance, transport fats, and remove waste products from tissues. Together, they work to support the immune system, filter out pathogens, and maintain overall health.
When an infection spreads from the appendix, bacteria or other pathogens can enter the lymphatic system through lymphatic vessels. These pathogens can then travel through the lymphatic system and eventually reach the bloodstream. Once in the bloodstream, the infection can be carried to other parts of the body, leading to systemic illness.
Lymph functions A lymph function is a defence that removes bacteria and foreign materials preventing infection and helps remove excess fluids. A lymph vessel is something that has valves along its length to prevent backflow of the fluid being carried to the nodes. Lymph nodes Lymphatic nodes can clean lymphatic fluid by filtering toxins. Produce lymphocytes, antibodies and antitoxins to fight infection and ingest pathogens. The following explains how the lymph interacts with the blood in the circulatory system ž Plasma in blood seeps through capillary walls. ž Plasma becomes tissue fluid and produces cells with nutrients and oxygen. ž Excess tissue fluids with waste passes into the lymphatic capillaries. ž Tissue fluids becomes lymph ž Clean lymph fluids pour into the subclavian veins to become part of the blood
Cancer cells that break free and travel to other parts of the body through the bloodstream or lymphatic system are called metastatic cancer cells.
White blood cells have their own lymphatic system which they travel around the body in. They are made in the lymph nodes. - I suppose the reason they don't stay in the blood is because of the pressure. Becuase the white blood cells are mostly within the lymphatic system, an immune response can be coordinated faster. - I believe.
At the cellular level, the cardiovascular system works with ALL the other body systems. Cardiovascular / Circulatory system: Circulates blood around the body via the heart, arteries and veins, delivering oxygen and nutrients to organs and cells and carrying their waste products away. Digestive system / Excretory system: The cardiovascular system helps bring extra fluids into the small intestines, and draws the water back out of the large intestines. The blood carries this to the kidneys to be processed. Endocrine system: Hormones travel through the bloodstream to the organs. Integumentary system/ Exocrine system: Blood flow to the skin helps warm us and keep us cool. Lymphatic system / Immune system: The blood stream assists lymph drainage. Muscular system/Skeletal system: Blood carries CO2 out of muscle cells and brings O2 to muscles Bones supporting the body and its organs. Without blood flow, muscles would die--necrotic-- and cause pain to bones. Nervous system: Blood flow assists with sensory and motor nerves. Without blood, the brain would have ischemic attacks, e.g. strokes. Renal system / Urinary system: The blood carries wastes to the kidneys Reproductive system: Blood causes male erections and sustains a pregnancy. Respiratory system Hemoglobin on RBCs exchange CO2 and O2
Yes, white blood cells have the ability to migrate from the bloodstream and lymphatic system into other tissues. This process, known as diapedesis or extravasation, allows white blood cells to travel to sites of infection or inflammation to combat pathogens and protect the body.

Lacteals (lymph capillaries) and then the larger vessels of the lymphatic system. However, contrary to some textbooks, the smaller fatty acid molecules do actually travel in blood to the liver, via the hepatic portal vein.
Lymphatic obstruction is a blockage of the lymph vessels that drain fluid from tissues throughout the body and allow immune cells to travel where they are needed. Lymphatic obstruction may cause lymphedema, which means swelling due to a blockage of the lymph passages
