Description

Lymphatic system 10 – Homeostasis in body systems: Integumentary system: - Lymphatic vessels drain the excess interstitial fluid and any leaked plasma proteins from the dermis of the skin. - The immune system cells which are called intraepidermal macrophages are what help protect the skin - Lymphatic tissue provides IgA antibodies in sweat.

Skeletal system: - Lymphatic vessels drain excess interstitial fluid and plasma proteins from the connective tissue around bones.

Muscular system: - Vessels drain excess interstitial fluid and plasma proteins from the muscles.

Endocrine system: - Lymph flow can help distribute some hormones and cytokines - Drain excess interstitial fluid and plasma proteins from endocrine glands Cardiovascular system: - Lymph returns excess fluid that is filtered from blood capillaries and the leaked plasma proteins to the venous blood. - Macrophages located in the spleen, destroy aged blood cells and remove any debris from the blood. Respiratory system: - Tonsils, alveolar macrophages and mucosa associated lymphatic tissues are what help protect the lungs from pathogens. - The lymphatic vessels drain excess interstitial fluid from the lungs. Digestive system: - Tonsils and MALT defend against toxins and pathogens that are able to penetrate the body from the gastrointestinal tract. - The digestive system provides IgA antibodies in saliva and gastrointestinal secretions - Lymphatic vessels are able to pick up absorbed dietary lipids and fat-soluble vitamins from the small intestine and then transport these to the blood. - Drain excess interstitial fluid and plasma from organs of digestive system Urinary system: - Drain excess interstitial fluid and plasma proteins from organs of urinary system - MALT is what helps to defend the urinary system against toxins and pathogens able to penetrate the body via the urethra.

Reproductive systems: - Lymphatic vessles drain excess interstitial fluid and plasma proteins from these organs - MALT is what helps to defend against toxins and pathogens that are able to penetrate the body via the vagina and the penis. - Females, sperm deposited in vagina are not attacked as foreign due to inhibition of immune responses. - IgG antibodies are able to cross the placenta providing protection to foetus. - Lymphatic tissue provides IgA antibodies in milk when breastfeeding....
