BIOS 255 WEEK 5 Lab 5 - Key Lymphatic System & Disease Resistance 1. Describe lymphatic system functions. Along with the veins, the lymphatic system is responsible for draining fluid from the body tissues. In concert with the blood cells, it provides mechanisms for defense against disease and promotes repair of damaged tissues. 2.
Lymphatic System & Disease Resistance 1. Describe lymphatic system functions. The lymphatic system helps fluids circulate the body and helps defend against agents that cause disease. 2. Locate each of the following lymphatic vessels: right lymphatic duct, thoracic (left lymphatic) duct, right and left subclavian veins, and cisterna chyli.
BIOS255 BIOS 255 WEEK 5 Lab 5 - Lymphatic System & Disease Resistance 1. Describe lymphatic system functions. The primary functions of the lymphatic system are to drain and return interstitial fluid to the blood to absorb and return lipids from the digestive system to the blood, and to filter fluid of pathogens, damaged cells, cellular, and cancerous cells to help protect against invasion. 2. Locate each of the following lymphatic vessels: right lymphatic duct, thoracic (left lymphatic) duct, right and left subclavian veins, and cisterna chyli.
Hormones, internal secretions that help to control important body processes are also transported by blood to target organs. White blood cells are collectively called leukocytes and they play a major role in fighting infections and diseases. Blood helps to regulate the temperature in the body by absorbing large quantities of heat produced by the liver and the muscles; this is then transported around the body to help maintain a constant internal
Cardiovascular system has three main functions: Transport of nutrients, oxygen and hormones to cells throughout our body and removal of metabolic wastes such as (carbon dioxide and nitrogenous wastes). Protections of the human body by while blood cells, antibodies and complement proteins that circulate in the blood and defend our body against foreign microbes and toxic. Clotting mechanisms are also present that protect the human body from blood loss after injuries. Regulation of body temperature, fluid pH and water content of
Epithelial cells that produce secretions are called gland cells. Individual gland cells are scattered with other cells in an epithelium. In a glandular epithelium, most or all of the cells produce secretions and they are discharged as “exocrine”. Exocrine is discharged onto the surface of the epithelium. “Endocrine” secretions are released into the surround tissue fluid and blood.
The lymph vessels collect fluid, called lymph from the body tissues and return it to the blood, maintaining the fluid balance within the body. Lymph filters through the lymph nodes, which are packed with white blood cells known as lymphocytes. These are produced in the bone marrow, spleen and thymus, and they help to protect the body against infections. Spleen: This is the largest lymphatic organ. It is located on the left side of the body just above the kidney.
Reabsorption in the main sites of the Kidneys. Reabsorption in the proximal Convoluted tubule (PCT) The PCT is the main site of reabsorption it is here that most of the materials will be reabsorbed into the blood. The materials are not directly absorbed straight into the blood first the move through the cells of the PCT and taken into the interstitial fluid.From here the molecules will diffuse into the blood through capillaries. The molecules that are reabsorbed are glucose, water Na+ and amino acids. All of the glucose and amino acids are reabsorbed at this site as well as around 85% of mineral ions.

The CSF has two functions its primary function is to act as a shock absorber for the central nervous system. The secondary functions to circulate nutrients and remove waste products from the brain. Doctors use this fluid in diagnosing many different diseases involving the nervous system including Multiple Sclerosis. In MS doctors examine
