2. Compare the development of lymphocytes with other formed elements. B lymphocytes develop in red bone marrow‚ T lymphocytes develop in red bone marrow and mature in the thymus; the other formed elements develop in red bone marrow 3. What is erythropoiesis? Which factors speed up and slow down erythropoiesis? Erythropoiesis is the process by which red blood cells (erythrocytes) are produced. If you lose a lot of blood‚ erythropoiesis will speed up; anemia can cause erythropoiesis to slow down

Fluid‚ Electrolyte‚ and pH Balance 1. The maintenance of normal volume and composition of extracellular and intracellular fluids is vital to life. List and briefly describe the kinds of homeostasis involved. In males and females‚ intracellular fluid has a greater proportion of total body water than does extracellular fluid. Give-and-take between the ICF and the ECF happens across plasma membranes by osmosis‚ diffusion‚ and carrier-mediated transport. The kinds of homeostasis involved are fluid

A&P – P 1 OF 2 This course is a study of “Human Anatomy and Physiology.” Humans can be classified as: - Animals (we are multicellular‚ motile organisms that lack cell walls) - Vertebrates (we have backbones) - Mammals (we have hair‚ mammary glands‚ 3 bones in each ear) - Primates (we have opposable thumbs‚ 2 clavicles‚ forward facing eyes) - Hominids (we are bipedal and have a large brain size to body size ratio). Anatomy is the study of animal structure. The word comes

Anatomy and physiology of the brain and spinal cord The brain is a spongy organ made up of nerve and supportive tissues. It is located in the head and is protected by a bony covering called the skull. The base‚ or lower part‚ of the brain is connected to the spinal cord. Together‚ the brain and spinal cord are known as the central nervous system (CNS). The spinal cord contains nerves that send information to and from the brain. The CNS works with the peripheral nervous system (PNS). The PNS
