Hypertension effects on heartBilim
In pathologic conditions such as "systemic hypertension" (elevated arterial pressure in the systemic circulation), the left ventricle must perform even more pressure work than it does normally. Because aortic pressure is elevated, the left ventricular wall hypertrophies (thickens) as a compensation for the increased workload.

Aging and arteriesBilim
The characteristics of the arterial walls change with increasing age: The walls become stiffer, less distensible, and less compliant. At a given arterial pressure, the arteries can hold less blood. Another way to think of the decrease in compliance associated with aging is that in order for an "old artery" to hold the same volume as a "young artery", the pressure in the "old artery" must be higher than the pressure in the "young artery". Indeed, arterial pressures are increased in the elderly due to decreased arterial compliance.

LymphocytesBilim
T lymphocytes (T cells) are so named because they undergo differentiation in the thymus. B lymphocytes (B cells) are so named because they were first recognized as a separate population in the bursa of Fabricius in birds or bursa-equivalent organs (e.g., bone marrow) in mammals. Natural killer (NK) cells develop from the same precursor cell as B and T cells and are so named because they are programmed to kill certain types of transformed cells.
