lymphatic system
The network of vessels that returns fluid to the bloodstream is called the Lymphatic System.
The structure responsible for the restriction of movement of large complex substances into the bloodstream is the endothelial cells that line blood vessels. These cells form a barrier known as the blood-brain barrier, which regulates the entry of substances from the bloodstream into the brain and spinal cord to protect the central nervous system.
Lymph is interstitial fluid that drains from the blood vessels and goes into the interstital space. Lymph retruns to the blood stream via the lymphatic vessels that drain into the subclavian vein.
The respiratory system is responsible for obtaining oxygen from the air and delivering it to the bloodstream. This process occurs in the lungs, where oxygen is inhaled and then diffuses into the blood vessels surrounding the air sacs called alveoli.
Fat reenters the bloodstream through lymphatic vessels known as lacteals. These vessels are located in the small intestine and absorb dietary fats in the form of chylomicrons, which are then released into the bloodstream to be delivered to tissues for energy or storage.
called lacteals. They are responsible for absorbing dietary fats and transporting them to the bloodstream. This process helps in the digestion and absorption of lipids in the small intestine.
Endothelial tissue, which lines the inner walls of blood vessels, is directly exposed to the bloodstream in the human body. These cells help regulate blood flow, transport nutrients and oxygen, and facilitate the removal of waste products.
If fiberglass fibers get into the bloodstream, they can cause irritation and inflammation of the blood vessels. In severe cases, this can lead to blood clots or blockages in the vessels. It is important to seek medical attention if fiberglass enters the bloodstream.
The circulatory system, specifically the blood vessels, is responsible for distributing nutrients to other parts of the body. Nutrients are transported in the bloodstream to various tissues and organs where they are needed for cellular functions.
The capitularies are responsible for bass exchange
One-way valves inside the lymphatic vessels prevent the backflow of lymph, helping to maintain a unidirectional flow towards the heart. This structural design ensures that lymph is pushed in the right direction, from the tissues towards the bloodstream.
Fats that are unable to be transported by the bloodstream are absorbed by the lacteals. They are lymphatic vessels.
