1. What are two major functions o the lymph node. a. Body Defense b. WBC Formation c. Maturation of T Cells d. Storage of RBC’s e. Both a & B f. Both a & C 2. What is a function of the lymphatic system g. Absorb digested fats h. Produce & Mature immune cells i. Reabsorb extracellular fluid & Return it to the bloodstream j.
What are the thymus gland functions? The thymus functions chiefly to develop T lymphocytes. Once mature, these cells leave the thymus and are transported via blood vessels to the lymph nodes and spleen. T-lymphocytes are responsible for cell mediated immunity, which is an immune response that involves the activation of certain immune cells to fight infection. 4.

Homeostatic Imbalance/Unit 8 Assignment William Thornbury Introduction to Anatomy and Physiology SC121 Instructor: Eric D. Steelman, DHSc(c), MPH, MS, RLATG 10/17/14 Homeostatic Imbalance The endocrine system helps regulate and maintain various body functions by synthesizing (making) and releasing hormones, chemical messengers. The major areas of control and integration include responses to stress and injury, growth and development, absorption of nutrients, energy metabolism, water and electrolyte balance, reproduction, birth, and lactation. The endocrine system is composed of glands that release their hormones directly into the bloodstream for chemical signaling of target cells. Typically, the body synthesizes hormones in one part and transports it to another through the bloodstream or lymph. Endocrine glands have a rich blood supply through which hormones travel to reach their target organs.

Hormones and Behaviors Ronnie Gordon BEH/225 8/21/2015 George Green Hormones and Behaviors The Endocrine system is how the human body communicates feelings and emotions. Along with the endocrine system, the nervous system works to assist the lungs with breathing. Both the endocrine system and the nervous system work together to make the heart to pump as well as assist the brain in making decisions. The endocrine system works by using hormones or chemical responses to affect the physiological activity inside a person’s body. Hormones cause cells to activate and once activated, the cells must have a receptor spot for the hormone.
Genetics Intro and Stem Cell Medical Research Lab Names: Period: Ref. : learn.genetics.utah.edu/content/begin/tour/ (copy and paste this link into your browser) Select Tab: “What is DNA” 1. What are the 4 letter “bases” found in a DNA coil? 2. How do the 4 letters always pair?
The endocrine activity is also controlled by hormonal stimuli or changes in the levels of circulating stimuli. The hypothalamus provides the highest level of endocrine control by acting as an important link between the nervous and endocrine systems. (pg
Hormones are chemical messengers secreted by the endocrine glands or other glands in the body. These chemical messengers send messages between cells. Hormones take many different actions in the body. They can stimulate or inhibit growth, trigger or suspend programmed cell death, activate or inhibit the immune system, regulate metabolism, and prepare for new activity or phase of life. They can also control the making and releasing of other hormones.
